Going to share some nice 4k wallpapers from our 3D models over on twitter shortly. Here's the link if would like to snag some of those. twitter.com/thebrianmcmanus
I just wanted to say thank you for all the hard work you do on these videos, surely they are serving as inspiration for a new young generation of engineers. Keep it up!
@@RealEngineering Sorry, but its not even a Turbo ramjet, it doesn't use ram compression for the after burning bypass. There is a link to a playlist of documentaries and interviews in my last comment, i suggest you look at some of those videos and see for yourself.
To Think That We Had The Worst Technology In The 1950's & They Had This Futuristic Machine MAKES ME WONDER What Else Was Made & What Technology Was Stashed From The Public
Wade but even if they had the technology, they most likely just had more current technology stuffed together to make a more powerful thing, instead of a more efficient system. Like there’s no way they had the format and size and efficiency of modern technology but they could’ve had the same level of power with older technology. You get what I’m saying?
My step Dad, now 95 years next month, November 2020 was the lead engineer for the SR-71 engine, when he worked for Pratt and Whitney Aircraft back when we all lived in Connecticut. I forwarded this to him today. Lots of memories for him.
It actually softens, it doesn't melt. It can cause the metal to creep at stress points. Most materials tend to soften as their temperature rises. A very stark example is certain plastics like polyethylene have glassy properties below certain temperatures. It's not a smooth transition, it happens quite suddenly.
I served with the 9th SRW in the early 70's in the Supply section (they call it Logistics now). We had a list of all the items that could (and could not) be used near the aircraft, down to even the brands of coffee. The tools used were all deplated, ie soaked in acid to remove the outer layer of rust protection. We were told this was to remove the cadmium from the tools, which would react with the titanium in the aircraft. Then in mid 1973, someone came up with a money saving idea (yes, they received an award) that every maintenance man on the line did not need his own tool kit, that each shop could have a couple of sets for everyone to use. So, there was a mass turn in of wrenches, screwdrivers, sockets, etc to us in Supply. However, we could not declare them as serviceable item because they did not have plating, and needed to be sprayed with protectant to keep them from rusting. We tried to send them to Redistribution and Marketing (Surplus Sales), but they refused to take them because they looked serviceable. These were the early days of $800 hammers and $1200 toilet seats, and they were wary of trouble. Typical Catch-22, not serviceable, not unserviceable. We were locked down during the October 1973 Israeli war, (flying missions over the Suez from New York and then South Carolina), we had 4 large (pallet sized) boxes of tools that were "Redistributed " to people in the wing. Problem solved. I am proud to have worked with the Blackbird, my part of it included keeping 70 lb and 140 lb rolls of film in refrigerated storage sorted by pull date, and getting up at 4 in the morning in our Operating Location to help put drip pans under the Aircraft after it had taken pictures of jungle.

I was under the impression that the Sr-71, or Rs-71 XD, used two different types of fuel. JP7 for getting off the ground and another when refueled. Do you have any first hand knowledge of this?
@NOVA Guy Yeah, except the video is for people who love the SR-71, so I was kind of appealing to them. But I'm sure the aliens will appreciate your comment when they get here.
imagine.. this thing is 50 years old.. what do they have today.. it is awesome to think about what technologies they developed that we dont even know about.. I mean, the engineering behind this plane is simply stunning edit: grammar
The coolest thing about the blackbird, seeing footage of it creeping out of a hangar you’d swear the plane was just revealed the day before, but then you see the chase cars from the 60’s to show its actual age. Beautiful plane
Some people call it the fastest, highest flying and most badass aircraft ever build... They are of course wrong. It is the slowest and lowest flying spaceship ever build. Only badass part is right. :)
@@mattclark5866 3 dislikes versus 1k likes is one of the best ratios I have seen. On a lot of videos the ratio is ~1:10. I still don't get why someone would dislike a SR-71 video (could be a former tsar).
@@howtogaintime739 you know how hard it could be for non academics and non industry professionals to get literature on highly niche topics? Local libraries usually only have introductory texts to a lot of stuff like this. The internet is a much more efficient method of information proliferation than books ever could be or ever were. Although they also increase the amount of false information out there, which is the risk, but the rewards have far surpassed the risks in that regard, even despite all the insanity with stuff like "fake news" and what not.
I prefer the A-12, just because no-one remembers it. And it was the precursor of the SR-71. The SR-71 just was a bit more developed version. en.wikipedia.org/wiki/Lockheed_A-12
My grandfather, James Plummer, got to fly in an SR-71B when he was Under Secretary of the Air Force. He remarked on his experience in a letter to me before he passed away: "...it was the smoothest flight I have ever made in any airplane. Even at the minimum turn radius permitted in the aircraft, there was no sensation of Gs or any other discomfort. Most spectacular, of course, was to sense the extremely high altitude where the sky is near black rather than blue and where cumulus clouds are in miniature. The only sensation of speed was watching the digital navigator tick of the miles, one every two seconds."
Caden Howlett That is incredible. And to think, your grandfather flew this. This plane still looks futuristic. I would love to hear more pilots stories from this era.
When in middle school and high school I loved planes like the SR-71 but after going to school for mechanical engineering and learning how each of these individual parts work, I have so much more of an appreciation of what a work of utter genius this plane is. The question they always asked was, how can we get more. And no matter what the obstacles were that stood in the way, they still managed to find a way to make it work. Even more key, they were able to do it WITHOUT compromising their previous breakthroughs. THAT is what makes this such an incredible plane. There were no tradeoffs in the engineering. They somehow managed to make EVERYTHING work together. I will forever be enamored with this plane. It's just nuts.
If anyone wants to see an SR-71 in person, there’s one in the Dulles Air and Space Museum in Northern Virginia. It has a bunch of other aircraft, but the SR-71 is pretty much one of the highlights of the museum. It’s massive, and the lights at the bottom make it absolutely menacing. Definitely worth it in my opinion.
There were a lot of things we couldn't do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment. It occurred when Walt and I were flying our final training sortie. We needed 100 hours in the jet to complete our training and attain Mission Ready status. Somewhere over Colorado we had passed the century mark. We had made the turn in Arizona and the jet was performing flawlessly. My gauges were wired in the front seat and we were starting to feel pretty good about ourselves, not only because we would soon be flying real missions but because we had gained a great deal of confidence in the plane in the past ten months. Ripping across the barren deserts 80,000 feet below us, I could already see the coast of California from the Arizona border. I was, finally, after many humbling months of simulators and study, ahead of the jet. I was beginning to feel a bit sorry for Walter in the back seat. There he was, with no really good view of the incredible sights before us, tasked with monitoring four different radios. This was good practice for him for when we began flying real missions, when a priority transmission from headquarters could be vital. It had been difficult, too, for me to relinquish control of the radios, as during my entire flying career I had controlled my own transmissions. But it was part of the division of duties in this plane and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. Walt was so good at many things, but he couldn't match my expertise at sounding smooth on the radios, a skill that had been honed sharply with years in fighter squadrons where the slightest radio miscue was grounds for beheading. He understood that and allowed me that luxury. Just to get a sense of what Walt had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Los Angeles Center, far below us, controlling daily traffic in their sector. While they had us on their scope (albeit briefly), we were in uncontrolled airspace and normally would not talk to them unless we needed to descend into their airspace. We listened as the shaky voice of a lone Cessna pilot asked Center for a readout of his ground speed. Center replied: "November Charlie 175, I'm showing you at ninety knots on the ground." Now the thing to understand about Center controllers, was that whether they were talking to a rookie pilot in a Cessna, or to Air Force One, they always spoke in the exact same, calm, deep, professional, tone that made one feel important. I referred to it as the " Houston Center voice." I have always felt that after years of seeing documentaries on this country's space program and listening to the calm and distinct voice of the Houston controllers, that all other controllers since then wanted to sound like that, and that they basically did. And it didn't matter what sector of the country we would be flying in, it always seemed like the same guy was talking. Over the years that tone of voice had become somewhat of a comforting sound to pilots everywhere. Conversely, over the years, pilots always wanted to ensure that, when transmitting, they sounded like Chuck Yeager, or at least like John Wayne. Better to die than sound bad on the radios. Just moments after the Cessna's inquiry, a Twin Beech piped up on frequency, in a rather superior tone, asking for his ground speed. "I have you at one hundred and twenty-five knots of ground speed." Boy, I thought, the Beechcraft really must think he is dazzling his Cessna brethren. Then out of the blue, a navy F-18 pilot out of NAS Lemoore came up on frequency. You knew right away it was a Navy jock because he sounded very cool on the radios. "Center, Dusty 52 ground speed check". Before Center could reply, I'm thinking to myself, hey, Dusty 52 has a ground speed indicator in that million-dollar cockpit, so why is he asking Center for a readout? Then I got it, ol' Dusty here is making sure that every bug smasher from Mount Whitney to the Mojave knows what true speed is. He's the fastest dude in the valley today, and he just wants everyone to know how much fun he is having in his new Hornet. And the reply, always with that same, calm, voice, with more distinct alliteration than emotion: "Dusty 52, Center, we have you at 620 on the ground." And I thought to myself, is this a ripe situation, or what? As my hand instinctively reached for the mic button, I had to remind myself that Walt was in control of the radios. Still, I thought, it must be done - in mere seconds we'll be out of the sector and the opportunity will be lost. That Hornet must die, and die now. I thought about all of our Sim training and how important it was that we developed well as a crew and knew that to jump in on the radios now would destroy the integrity of all that we had worked toward becoming. I was torn. Somewhere, 13 miles above Arizona, there was a pilot screaming inside his space helmet. Then, I heard it. The click of the mic button from the back seat. That was the very moment that I knew Walter and I had become a crew. Very professionally, and with no emotion, Walter spoke: "Los Angeles Center, Aspen 20, can you give us a ground speed check?" There was no hesitation, and the replay came as if was an everyday request. "Aspen 20, I show you at one thousand eight hundred and forty-two knots, across the ground." I think it was the forty-two knots that I liked the best, so accurate and proud was Center to deliver that information without hesitation, and you just knew he was smiling. But the precise point at which I knew that Walt and I were going to be really good friends for a long time was when he keyed the mic once again to say, in his most fighter-pilot-like voice: "Ah, Center, much thanks, we're showing closer to nineteen hundred on the money." For a moment Walter was a god. And we finally heard a little crack in the armor of the Houston Center voice, when L.A.came back with, "Roger that Aspen, Your equipment is probably more accurate than ours. You boys have a good one." It all had lasted for just moments, but in that short, memorable sprint across the southwest, the Navy had been flamed, all mortal airplanes on freq were forced to bow before the King of Speed, and more importantly, Walter and I had crossed the threshold of being a crew. A fine day's work. We never heard another transmission on that frequency all the way to the coast. For just one day, it truly was fun being the fastest guys out there.
Unforuntately this has been shown to probably not be true. Great story though: www.reddit.com/r/todayilearned/comments/8x5ndw/til_when_the_sr71_was_retired_in_1990_it_went/e21c0jt/
Dave Churchill great story. So outside the window of the small population that could relate to this story tho... so I would have no clue if it were true or not... your assessment has detracted from my reading experience. Hopefully due to truth and not due to the troll epidemic that has graced internet culture. Edit: he does have a linguistic similarity to online erotica... I’ll say that much
I agree, you went back on that horse real fast. Congratulations, my interest is renewed. Plus I'm glad you expressed your concerns, it made me feel connected to your work in a special way.
CIA: Yes The SR-71 predecessor was actually an aircraft developed by the CIA. Surprised it wasn’t mentioned. Airforce planes piloted by CIA, not Airforce pilots.
No, they were CIA planes. It’s actually why lots of the SR-71 was so ramshackle. They couldn’t design a brand new Mach 3 engine. They had to make one out of an engine designed for a flying boat. They had to figure out a starting system for it using a couple of Buick V8s because no existing APUs or air starters were powerful enough.
This isn't unusual for Jet aircraft. The Challenger 300 for example has multiple Fuel/Oil heat exchangers, and Hydraulic/Fuel heat exchangers. The Hydraulic lines are simply routed INSIDE then out the fuel tank which dissipates some of the heat of the Skydrol Hydraulic fluid which is under very high pressure
@@skiebroth2462 at least in the third world, we don't pretend to be a know it all smartass when we don't understand something. A trait that you should consider to integrate to your annoying self
Probably my favorite plane. The SR-71 Blackbird and the A-10 Warthog. I know that they're on the opposite ends of the spectrum in just about every way, but they're both incredible places. The Blackbird designed around an engine, the Warthog designed around a gun.
Grandad was a P-47 Thunderbolt fighter pilot in WWII in the pacific theater. Passed away in ‘02, but man can I remember some of his stories…(miss you grandad❤) never did he think that his daughter (my mom) would marry a guy who was in flight school who would spend the next 25 some years flying none other than the A-10 Thunderbolt II, the Hog. Upon retiring my dad was given one of the barrels from the Gau-8 Avenger Gatling gun mounted on a beautiful one-piece of solid mahogany for wall mounting. But being my dad, he had to one-up that; he had the barrel removed from its mount and had the entire thing custom-dipped into a vat of liquid chrome, both it and the unfired round he got with it. Fast-forward to now and you go into his office adorned with all sorts of badass A-10 memorabilia and all of it kinda fades away at the sight of the barrel with its bullet both in flawless/fingerprintless, flawless shiny chrome. 🤤 Suffice it to say, the Warthog is very near n dear to me. But the SR-71 is, most definitely, solidified as a close runner-up. _She is the uncontested absolute King of the Skies. And she only ever flew for the Red White N Blue_ ❤🫡🇺🇸
Titanium can be tough to work on but the stainless steel alloys can be a nightmare in the machine shop. Hastalloy, Inconel and the other wear resistant alloys work harden quite easily and will make you pull your hair out !! I just cant imagine working on this stuff back in the late fifties. Lots of respect to those machinists and engineers !
From the era of slide rules and #2 pencils comes one of the most technologically advanced pieces of engineering ever. Setting records even on her last flight. Superb film! Excellent presentation!
My grandfather flew one of these. Fun fact, Titanium was extremely rare outside the USSR. So the US gov't set up a hoard of shadow companies to buy titanium from the Soviet union to build these. That's right, we spied on Russia with Russian metal.
Edwin Jansen YES! It’s purpose was defeating the evil empire of the Soviet Union! Mission Accomplished! 🇺🇸 That makes the SR-71 even more beautiful! And has been used by NASA for scientific research as well!
Holy shit they essentially put a jet engine in a jet engine wtf! I knew this plane looked cool but wow this is some insane engineering! Thanks for the awesome video!
No, they adjust a cone inside a venturi to pressurize the airflow as needed...airspeed utilization. Insane NO, Clarence L. "Kelly" Johnson surrounded himself with sharp engineers. INSANE IN THIS CONTEXT IMPLIES THAT YOU SHOULD BE wowed...... In essence they created a natural first stage compressor, the turbine would have increased MUCH in weight with a mechanical first stage.
Walter: Well, we do have one option. However, it was decommissioned in 1998. Alucard: The Lockheed SR-71 Blackbird. An advanced long-range strategic reconnaissance aircraft capable of Mach 3 at an altitude of 85,000 feet. Integra: You sure do seem to know a lot about it. Alucard: DO YOU EVEN READ MY CHRISTMAS LIST?!
Satellites? Because it was satellites. Spy planes are still useful though. Satellites are predictable and if you are fast you can move things out of their sight quickly.
@@RealEngineering So predictable I even managed to take a photo of one of them. Unfortunately, it isn't moch more than a bunch of blue pixels, I need better equipment :)
Mig-25s (and Mig-31) played a role as well. Although they are not as fast (Mig-25s can fly Mach 3 but it will cause severe engine damage), they can fly as high and close enough to potentially fire Mach 3+ AA missiles. At those speeds AA missile avoidance is impossible. It is the same reason why XB-70 was cancelled. After U-2 shot down incident, US stopped all Soviet flyovers.
@@RealEngineering Well, at the time (1999) I was working inside 'The Beltway' (Metro Washington, D.C.). We were not government or military. According to the 'knowledgeable' among our group we (the US) had a vehicle that could get people "anywhere in the world within 90 minutes". That sounded like some sort of ballistic transport. I agree satellites can 'see' everywhere. But they cannot transport. Anyway, the conversations my fellow 'unknowledgeables' and I had on this topic have long stayed with me. I mean, they created the SR-71 in the 50's. Imagine what was created in the 90's that we still wont know about for some time?
I was speaking with someone recently who used to design propellers for submarines. He was contracted once by the Swedish Navy because of a design flaw in one of their new subs, the prop was too noisy. I asked him how he figured out what the problem was and he told me with his slide rule!!!! I couldn't believe it, with computer technology this guy was still using s slide rule!
I have been researching about this beast for a very long time. i have the same theme for this on my car(R32 GTR Gunmetal colour). You did a great job in summarizing this all in one video. I used to know a guy who was stationed in Okinawa - He told me that it was so excruciatingly loud on take off.. the whole town knew when one of these were there!
I see things like this all the time given the current situation with masks. (I'm talking about COVID-19 for all you future readers that will have forgotten about the Great Plague of 2020). People will walk around with their masks on their forehead or chin, until someone gets near them. Then they pull them down. After that person leaves their vicinity, they partially remove them and scratch their nose, rub their eyes, touch their mouth; having just touched all the stuff around them moments before. But I don't know what's a bigger waste of time because I often see the following as well: Two people with masks on approach each other and begin to talk. After a moment of talking, they both remove their masks off their mouths so they can talk easier. Then as they leave their close proximity, they put their masks back on. I don't think people understand how masks and gloves work.
@J B Yes, I was being completely sarcastic. Though it will be interesting to see how this plays out in future references to this time. I mean the entire world is dealing with this in one respect or another. I was at a auto dealership the other day and noticed that a family had just bought a car and having their picture taken next to it. They were wearing their masks around their chins and over their mouths but not their noses as you described. Before the photo I heard them mention to the car salesman to wait a moment while they put their masks on so they could remember the time when they bought their car during the pandemic. This has been a life changing time for many people with the economy failing, jobs lost, families and friends separated, and lifestyles changed drastically in so many areas. Of course, it has devastated families with lives lost, and not to sound heartless, but that's life in general every year, but a plague? Certainly not on the scale of past plagues in history, and let's hope that continued stupidity with people ignoring common sense approaches to health does not allow this or any other pandemic to grow to that scale.
I think we as humans have regressed with the advance in technology; that or we are no longer excited by advancement for its on sake. Everything is about cost and who consolidates power.
@@Belioyt I wouldn't say that, look at Spacex for example. And the SR-72 he mentioned at the end of the video. There's some amazing innovations happening, it's just not everywhere and it isn't done with the same limitations as a few decades ago.
If anyone could do it, the skunkworks and Kelly Johnson could... will for sure be remembered as the ultimate aerospace engineering firm / engineer of all time (in my opinion!) I am a huge fan of Jack Northrop also though.
I saw the SR-71 at the Boeing Museum of Flight in Seattle some years ago, and I was in awe, it is HUGE when you are standing near it and it is very intimidating, it looks like a deadly alien spaceship. It is hard to express with words, but it was the most powerful object I've ever seen in my life. A true marvel of engineering by many brilliant minds. Now if only we could use more of that kind of thinking for peaceful endeavors :)

@@fst-timer7107 Hahahaha, don't know what Chevy he was driving, but I get what he meant. It was probably laid out in a very similar way and I imagine thwy probably used some of the same process to build cockpit components that the chevy guys were doing on those 50 dashes.
This is definitely my favorite aircraft in history. And I appreciate this video since it cleared a misinformation I had regarding the leaking fuel issue. In a previous documentary (cannot remember what it was called or where I've seen it) they said that the leaking fuel was by design. Given the expanding and contracting properties of the fuselage, it was designed like this so the gaps would seal themselves during flight. Your video cleared that up for me, thank you!
This took a solid month to make, but definitely worth it! Going to make this "The Insane Engineering of ____" a series. Each one will have nice 3D renders like this and explore the engineering concepts in different machines.
Early on in development, the test pilots found out in the event of an unstarted engine that unstarting both engines and restarting them both at the same time was far safer than trying to restart the unstarted engine. So that eventually made into the engine management computer. This plane turned really badly due to the risk of unstarting an engine. Standard procedure to dodge a missile was to climb and accelerate. It couldn't outrun soviet missiles back then. Those could easily reach mach 4 already if launched from an already fast moving aircraft. But it flew so fast and so high the time between detection and scrambling interceptors meant it was already out of range by the time they could take off and climb for interception. Regarding SAMs, the tech at the time didn't allow for on-the-fly calculations of interception vectors, so instead they relied on radar pings, mening they would have to follow and then catch up to the SR for a kill. They ran out of fuel before they could catch it. By now, SAMs can detect and cut the corner to catch a Blackbird, making the plane tactically unwise to use. That's why the USAF retired it in 1998 with no plans for a replacement, until scramjet engines came along. The soviet plane of choice for interception would be either the MiG-25 or the 31 after 1975. Those could sustain Mach 2.8 greatly sacrificing range or Mach 3.2 while the engines destroy themselves. One SR-71 pilot claims he reached Mach 3.5 flying away from one interceptor. And speaking of the USSR, most of the Titanium for the SR-71 was purchased by CIA front companies in foreign countries from them.
Well, not 100% true as to why it was retired. Spy satelites are better(now, compared to back in 70-80) and cheaper in the long run to maintain. SR had to undergo full refit after flight due to damage those planes sustained on "normal basis" - like missing panels etc etc. JP7 awas also problematic - TEB is toxic and hard to handle, each flight == risk of running out of it. So all in all, it was expensive gamble to operate.
my brother married the daughter of one of the skunkwork engineers. lady is crazy as a loon. she tried to burn her parents house down with them inside. i met her father only once. seemed like a really nice guy. he talked about the fuel tanks that would leak when the aircraft was on the ground and the science around their design. It was way above my head. when her parents died they left her with a nice tidy sum which she promptly blew thru. that was money he earned building that airplane.
When I was in 3rd grade, one of my teachers had flown one of these for a living before retiring from the Air Force. I'm 46 now. It's insane that such a futuristic looking aircraft has been around so damn long. It's a gorgeous machine.
I've watched just about every SR71 documentary, and it never quells the pride I feel. From a little kid playing with the miniatures, to model airplanes of the thing, to an engineer that gets the work of thousands of engineers and scientists, it never gets old.
@@MulaBatiswaHutagaol it's it great? If you ever get the chance to go to Evergreen in Oregon, or the one hard in Arizona, it's like being a kid again. Srs, spitfires, guppies, spruce goose, it's like you're ten years old again.
Pretty much every engine uses fuel for cooling. Look up power enrichment. The phase change of fuel from liquid to vapour is one of the best air conditioners, ever.
@@iliketopumpit :) yes, indeed, you are correct. And I believe a lot of liquid fuel rocket engines do that, too. But still, the way I phrased it is technically correct AND cheesy, and I find it fun to put it this way. this aside, shout out to "Original Skunk Works" talk by Nicholas Means @ LeadDev; and Tim "The Everyday Astronaut" Dodd's video on Raptor Engine; those two videos are something I'd recommend to aviation/tech enthusiasts :) Cheers!
As a former SR-71 pilot, and a professional keynote speaker, the question I'm most often asked is "How fast would that SR-71 fly?" I can be assured of hearing that question several times at any event I attend. It's an interesting question, given the aircraft's proclivity for speed, but there really isn't one number to give, as the jet would always give you a little more speed if you wanted it to. It was common to see 35 miles a minute. Because we flew a programmed Mach number on most missions, and never wanted to harm the plane in any way, we never let it run out to any limits of temperature or speed. Thus, each SR-71 pilot had his own individual “high” speed that he saw at some point on some mission. I saw mine over Libya when Khadafy fired two missiles my way, and max power was in order. Let’s just say that the plane truly loved speed and effortlessly took us to Mach numbers we hadn’t previously seen. So it was with great surprise, when at the end of one of my presentations, someone asked, “what was the slowest you ever flew the Blackbird?” This was a first. After giving it some thought, I was reminded of a story that I had never shared before, and relayed the following. I was flying the SR-71 out of RAF Mildenhall, England , with my back-seater, Walt Watson; we were returning from a mission over Europe and the Iron Curtain when we received a radio transmission from home base. As we scooted across Denmark in three minutes, we learned that a small RAF base in the English countryside had requested an SR-71 fly-past. The air cadet commander there was a former Blackbird pilot, and thought it would be a motivating moment for the young lads to see the mighty SR-71 perform a low approach. No problem, we were happy to do it. After a quick aerial refueling over the North Sea , we proceeded to find the small airfield. Walter had a myriad of sophisticated navigation equipment in the back seat, and began to vector me toward the field. Descending to subsonic speeds, we found ourselves over a densely wooded area in a slight haze. Like most former WWII British airfields, the one we were looking for had a small tower and little surrounding infrastructure. Walter told me we were close and that I should be able to see the field, but I saw nothing. Nothing but trees as far as I could see in the haze. We got a little lower, and I pulled the throttles back from 325 knots we were at. With the gear up, anything under 275 was just uncomfortable. Walt said we were practically over the field-yet; there was nothing in my windscreen. I banked the jet and started a gentle circling maneuver in hopes of picking up anything that looked like a field. Meanwhile, below, the cadet commander had taken the cadets up on the catwalk of the tower in order to get a prime view of the fly-past. It was a quiet, still day with no wind and partial gray overcast. Walter continued to give me indications that the field should be below us but in the overcast and haze, I couldn't see it.. The longer we continued to peer out the window and circle, the slower we got. With our power back, the awaiting cadets heard nothing. I must have had good instructors in my flying career, as something told me I better cross-check the gauges. As I noticed the airspeed indicator slide below 160 knots, my heart stopped and my adrenalin-filled left hand pushed two throttles full forward. At this point we weren't really flying, but were falling in a slight bank. Just at the moment that both afterburners lit with a thunderous roar of flame (and what a joyous feeling that was) the aircraft fell into full view of the shocked observers on the tower. Shattering the still quiet of that morning, they now had 107 feet of fire-breathing titanium in their face as the plane leveled and accelerated, in full burner, on the tower side of the infield, closer than expected, maintaining what could only be described as some sort of ultimate knife-edge pass. Quickly reaching the field boundary, we proceeded back to Mildenhall without incident. We didn't say a word for those next 14 minutes. After landing, our commander greeted us, and we were both certain he was reaching for our wings. Instead, he heartily shook our hands and said the commander had told him it was the greatest SR-71 fly-past he had ever seen, especially how we had surprised them with such a precise maneuver that could only be described as breathtaking. He said that some of the cadet’s hats were blown off and the sight of the plan form of the plane in full afterburner dropping right in front of them was unbelievable. Walt and I both understood the concept of “breathtaking” very well that morning, and sheepishly replied that they were just excited to see our low approach. As we retired to the equipment room to change from space suits to flight suits, we just sat there-we hadn't spoken a word since “the pass.” Finally, Walter looked at me and said, “One hundred fifty-six knots. What did you see?” Trying to find my voice, I stammered, “One hundred fifty-two.” We sat in silence for a moment. Then Walt said, “Don’t ever do that to me again!” And I never did. A year later, Walter and I were having lunch in the Mildenhall Officer’s club, and overheard an officer talking to some cadets about an SR-71 fly-past that he had seen one day. Of course, by now the story included kids falling off the tower and screaming as the heat of the jet singed their eyebrows. Noticing our HABU patches, as we stood there with lunch trays in our hands, he asked us to verify to the cadets that such a thing had occurred. Walt just shook his head and said, “It was probably just a routine low approach; they're pretty impressive in that plane.” Impressive indeed. Little did I realize after relaying this experience to my audience that day that it would become one of the most popular and most requested stories. It’s ironic that people are interested in how slow the world’s fastest jet can fly. Regardless of your speed, however, it’s always a good idea to keep that cross-check up…and keep your Mach up, too.As a former SR-71 pilot, and a professional keynote speaker, the question I'm most often asked is "How fast would that SR-71 fly?" I can be assured of hearing that question several times at any event I attend. It's an interesting question, given the aircraft's proclivity for speed, but there really isn't one number to give, as the jet would always give you a little more speed if you wanted it to. It was common to see 35 miles a minute. Because we flew a programmed Mach number on most missions, and never wanted to harm the plane in any way, we never let it run out to any limits of temperature or speed. Thus, each SR-71 pilot had his own individual “high” speed that he saw at some point on some mission. I saw mine over Libya when Khadafy fired two missiles my way, and max power was in order. Let’s just say that the plane truly loved speed and effortlessly took us to Mach numbers we hadn’t previously seen. So it was with great surprise, when at the end of one of my presentations, someone asked, “what was the slowest you ever flew the Blackbird?” This was a first. After giving it some thought, I was reminded of a story that I had never shared before, and relayed the following. I was flying the SR-71 out of RAF Mildenhall, England , with my back-seater, Walt Watson; we were returning from a mission over Europe and the Iron Curtain when we received a radio transmission from home base. As we scooted across Denmark in three minutes, we learned that a small RAF base in the English countryside had requested an SR-71 fly-past. The air cadet commander there was a former Blackbird pilot, and thought it would be a motivating moment for the young lads to see the mighty SR-71 perform a low approach. No problem, we were happy to do it. After a quick aerial refueling over the North Sea , we proceeded to find the small airfield. Walter had a myriad of sophisticated navigation equipment in the back seat, and began to vector me toward the field. Descending to subsonic speeds, we found ourselves over a densely wooded area in a slight haze. Like most former WWII British airfields, the one we were looking for had a small tower and little surrounding infrastructure. Walter told me we were close and that I should be able to see the field, but I saw nothing. Nothing but trees as far as I could see in the haze. We got a little lower, and I pulled the throttles back from 325 knots we were at. With the gear up, anything under 275 was just uncomfortable. Walt said we were practically over the field-yet; there was nothing in my windscreen. I banked the jet and started a gentle circling maneuver in hopes of picking up anything that looked like a field.How's it going gamers? Y'know, online dating is a modern day miracle.

The fuel leak information isn't entirely accurate. The truth is no sealant was ever found that would work at all temperature ranges. Instead, realizing the expansion properties of titanium, the gaps that allowed the leaks were deliberately engineered into the design. So when the aircraft got to operating temperature, the leaks were sealed off mechanically. The sealant applied to limit the leaks only ever worked at ground temperatures and shortly after take off. By the end of each mission the sealant was mostly useless.
You are correct. As a maintenance airman on the SR in the late sixties, I got to experience the leaking fuel and resulting drip pans for four years. Loved it.
That's also the reason for the grooves in the wings which you can see at 8:51. Thermal expansion could cause the wings to bend but instead now the grooves just get a little deeper and the wings remains straight.
Something else caught my eye, the leak table, showing Zone 15, Dry Bay areas, 950 cc/Minute/Side. That seems unbelievable. By my calcs, that 950cc is 1/4 Gallon. So that would be 2 sides x 1/4 gallon, per minute, or 1/2 gallon/minute. 720 Gallons/Day. Come on... I've never heard of a leak like that. Is that right? th-cam.com/video/3hYSnyVLmGE/w-d-xo.html
@ Muchen Tuchen You couldn’t be more wrong... lol. The US was almost completely dependent on British jet engines until well after WWII. The Soviet Union used German jet engines in the immediate postwar and bought British engines which they reverse engineered until they designed their own in the 1950s The first jet aircraft was indeed flown by Nazi Germany.
Crazy how this was built in the 60's, even if it was built today it would still look futuristic. God knows what kind of projects they're working on now.
@@nosamuigbinnosa4081 engineers back in the day didn't know calculus and built perfect 70km roads. Today's engineers can't do shit when Autocad breaks.
For my money, this aircraft represents a greater achievement than even the actual space program. Or at least equals it. The ability to fly in so many different regimes of flight is astonishing. The absolute controllability of all systems from idle speeds to ramjet mach 3+ speeds in everything from sea level air to very nearly not any air at the top of the atmosphere is just incredible.
It's a classic engineering understatement to refer to Unstarting as "a sudden yaw". Pilots were knocked unconscious several times. The "solution" was to detect the unstart and snuff the other engine. Pilots reawaken in the world's largest lawn dart on a course to slam into the ground at mach 2-3. Fortunately, they were starting from such a high altitude that there was time before impact to restart the engines and start aviating again. Compared to the risk of the aircraft killing you in a flat spin, Soviet missiles were not seen as dangerous.
Fascinating stuff. When I was a boy I had a model of the SR-71.I was intrigued then, and still am. When I got the model, it's specs were top secret. After watching your You tube documentary, I now know much more about the "Blackbird" that I didn't before. Cool stuff.

Hey, I know, let's end a few more myths about the SR-71. I was in ECM, was trained by SAC to work them so, in a pinch, I could be moved TDY to work them, and had friends who did work them. First, from what we were taught in 1972, the shape of the SR-71 was not just for speed. Contrary to what you have been taught about the FB-117, the SR-71 was the first plane to use shape for stealth. The U-2 was the first to use radar absorbing paint and materials for stealth. We could tell when the Ruskies were tracking an SR-71 because they would say something to the effect that eagles don't normally fly that fast because that is how big an SR-71 was on their scopes, which, if you are familiar with radar scopes, that alone would make them difficult to see. Imagine trying to track something on your radar scope that is the size of an eagle and traveling at Mach 3+. Just a wee bit difficult. Then, when you add in the ECM, which masked an already small picture on the scope, it was almost impossible to see. Plus the thing flew so fast that, if they entered the range of the scope just behind the radar sweep (I know this from talking to radar weenies) the plane could fly cross a significant part of the scope and out of range before the radar sweep could get back around and see the bird making it even harder to see. The way the Ruskies ended up having to track an SR-71 was to see it on one radar scope and tell another radar further down range the time, location, direction, and altitude of their siting and the next one or two radar units would note when they saw the bird, time how long it took to get there, and then have to calculate the speed of the plane for a guess shot with a missile. It was ye ole poke and hope. The bird was significantly faster than they tell you. They only tell you the "declassified" top speed not its actual top speed. That is still classified.
Add more than 25k ft to elevation... my dad flew A-12 Oxcarts and SR-71 for the "Company" and everyone in his squadron had astronaut patches on flight suites... the AF drivers were forbidden from going outside of the performance envelope. The Company drivers didnt have these restrictions... but because they flew so high above 100k ft most of them passed away from acute leukemia from over exposure to unshielded UV radiation from the sun. This is what my dad died from shortly after retiring.

As interesting as the 3D printed titanium parts are for the future planes, I'm much more impressed by the Blackbird's clever engineering from the 1960's.
Most of the SR-71's design came from the A-12 which was designed in the late 50's and built around the turn of the decade. Kelly Johnson and the Skunk Works were incredible.
"One day, high above Arizona, we were monitoring radio traffic pf all the airplanes below us. First of all, a Cessna pilot asked the Air Traffic Controller to check his ground speed. '90 Knots', ATC replied. A twin Bonanza made the same request. '120 on the ground' was the reply. To our surprise, an S-18 came on the radio with a ground speed check. I knew exactly what he was doing. Of course, he had a ground speed indicator on his cockpit, but wanted to let all the bug-smashers in the valley what real speed was. 'Dusty 52, we show you at 620 on the ground', ATC responded. The situation was too ripe. I heard the click of Walter's mike in the rear seat. In his most innocent voice, Walter startled the controller with a ground speed check from 81000 feet. In a cool professional, the controller replied, 'Aspen 20, I show you at 1,982 knots on the ground. We did not hear another transmission on that frequency all the way to the coast."

I was born and raised in Yuba City California, a 10 minute drive from Beale AFB, home of the SR-71 from 1966 to 1990 (when it was retired the first time). My dad would take my best friend Nick Jones and I to the air shows every year and all we cared about was the Blackbird. One of the highlights of my life was running into a very well known SR-71 pilot who was a member of the same gym Nick and I belonged to, and though in our 20's then I'm sure we looked like awestruck 10 year olds that day. It was a sad day when we realized we weren't going to hear those planes breaking the sound barrier over our town anymore.

It was only free because the US wouldn't allow Concorde to fly over their mainland. Of the two, I still nod towards an airliner that anyone could book a flight and sip champagne even though the SR71 was faster and higher. It was a staggering piece of commercial engineering on a par with the SR71's military engineering.
@@adventtrooper Concorde was really amazing but I can totally understand why they didn't fly over anything but the Ocean. Can you imagine some of those jet trails that you see be accompanied with a Sonic Boom? Talk about incredibly obnoxious, which is the exact reason they didn't do that.
I’m sure that many of the UFO sightings back in the 60’s and 70’s were due to top secret flight testing of planes such as this. Even today to see one roll out it looks like something state of the art for today. Actually it looks futuristic still. I can’t imagine what people thought about it if they saw it in the 60’s, not knowing that it even existed yet. It amazes me how advanced planes like this were built in such a short time period. I mean in 1945 99% of airplanes were slow lumbering piston engined airplanes. True, by the end of the war there were some very early turbojet fighters around that proved the concept and demonstrated the speeds that could be achieved. But the thrust was small and the failure rate was very high, with those surviving having very short overhaul periods. In a little over 15 years, engineers went from very few unreliable turbojets, to the incredibly reliable and incredibly complicated turbojets on the SR-71. And not only that plane but the Concorde as well. The only thing that made Concorde possible as a long range passenger jet was the fact that it could fly at Mach 2 without afterburner. Afterburner was used during takeoff, then was turned off during the noise abatement procedure. Then once they were over open ocean they would go to full throttle and turn the afterburners back on and leave them on until they made it to around Mach 1.7 I believe. Then they would leave the throttles at full, but shut off the switches to the afterburners. The Soviet supersonic passenger jet couldn’t be flown supersonically without the afterburners on all the time, greatly reducing the range. The engineers took a different route on Concorde. They installed a series of movable doors on the intake nacelle for each engine. Those doors were controlled by two computers for each engine, one being a backup. When supersonic, the doors would move to a position that would slow the incoming air to around 500mph, where the turbojet could use it and still generate adequate thrust. It amazes me that engineers in the 60’s designed these two advanced aircraft when only 2 decades earlier jets didn’t even exist in significant numbers. The sr-71 and the Concorde both look like they could be rolled out the door today and accepted as modern state of the art aircraft. Of course us and the Soviets were going into space during this time as well. It sure was a time of major technological advances and lots of major achievements.
When I was stationed on Okinawa, we used to watch the tanker take off and then the Habu (what we called the Blackbird) would come bouncing out of its hangar, line up and take off. Nothing better than the smell of JP7.
From one engineer to another, it's a joy listen to these videos. Your explanations are clear and just the right ratio of technical to approachable. As someone whose core educational training was in fluid dynamics, I can get very touchy sometimes when necessary simplifications in popular explanation obscure important truths. Your core simplifications are the most effective yet essentially correct I've ever seen in a more popular science oriented video. Well done.
I would be crying a lot if I'm there to see this thing at one of the museums that have them. I saw and read about this beautiful bird in a book when I was a kid far 700 kilometers away from Bangkok. Books were bery hard to find, and I can't read English back then, translated books were my only choice, even super more harder to find. I could only dreamed of how it would fly, it was all wonder for a kid in a developing country. A truly remarkable step of humanity for sure. Thank you for this great video. ❤️
I personally found the fuel storage part the most interesting. Always thought it would be in a long tank and insulated to keep it away from the scorching exterior when up to speed. Never would have guessed that it WAS the insulation for the plane's components.
Getting fuel hot isn't a problem because fuel by itself doesn't burn. As long as you don't allow oxygen in the tank and you have pressure valves it doesn't matter what temperature the fuel gets. Something like what happened with TWA 800 happened because there was oxygen in the tank. I don't know if the SR-71 had a nitrogen gas system or if they just didn't let the tank run dry. Liquid fuel doesn't burn, it's vapor that does and only within a certain ratio. The only time you have a risk of explosion is if you let the tank run dry.
@@nicksalvatore5717 do we need this though? With how high fidelity satellites are and how much more cost effective drones are I don't know if it makes sense to design something like the SR 71.
@@danaolsongaming exactly... when this was developed, that sort of capability was unheard of at the time. Just think of things that are unheard of at this point in time... that's what they're developing. Things you can't comprehend in this point in time.
I still can't get over the fact that they designed a plane with an engine that proved to be *too powerful* for the airframe even when they specifically used the best materials available to them, forcing them to cap the engine to a much lower level of power than it's actual maximum.
Kelly had a great team. With Kelly at the helm, they created the most impressive aircraft to ever fly the skies, still the world's fastest air breathing engine powered to this day! And she's been decommissioned since the 90s I believe
The range of the SR-71 was limited to approximately 11.5 hours, by the amount of liquid nitrogen stored in its dewars, used to inert and pressurize the fuel tanks. The inlet system was designed by Ben Rich and his small team. He was awarded the American Institute of Aeronautics and Astronautics Award in 1972 for designing the Blackbird's propulsion system. The SR-71 had "tactical limits" of Mach 3.35 with a maximum Compressor Inlet Temperature of 427 C. In addition to the air, by-passing the engine to the afterburner for additional cooling and thrust, the front of the inlet, with its associated doors and spike, provided an inlet duct pressure of 18 psi, while the outside air pressure at 82,000 ft. was only 0.4 psi. This large pressure differential provided a forward thrust vector, pushing on the back of the spike and providing 54 % of the total thrust, while 29 % was produced by the ejector, and only 17 % by the engine. The speed of the SR-71 was limited by thermal temperatures, recoveries from "unstarts", and the shock wave, coming off its nose, entering the inlets, creating "unstarts." Above 3.35 Mach, there was a high probability that the aircraft would be unable to recover, if an "unstart" occurred.
I had thought that triethylborane was the primary limitation on the max number of mid-air refuelings. I didn't know about the nitrogen tanks; thank you!
@@justinhannan1713 The SR-71 had 16 "shots" of TEB (Triethylborane) per engine, which was more than enough to accomplish its missions, regardless of their duration, 1 shot to start each engine, leaving the remaining TEB to relight its afterburners after refuelings or, in the event of a flameout, to restart the engine.

"Before their atoms begin to diffuse and slide over each other" - that has to be the most scientific way of saying "before it melts".

It actually softens, it doesn't melt. It can cause the metal to creep at stress points. Most materials tend to soften as their temperature rises. A very stark example is certain plastics like polyethylene have glassy properties below certain temperatures. It's not a smooth transition, it happens quite suddenly.

You really think that titanium melts at 300 degrees centigrade?
I served with the 9th SRW in the early 70's in the Supply section (they call it Logistics now). We had a list of all the items that could (and could not) be used near the aircraft, down to even the brands of coffee. The tools used were all deplated, ie soaked in acid to remove the outer layer of rust protection. We were told this was to remove the cadmium from the tools, which would react with the titanium in the aircraft. Then in mid 1973, someone came up with a money saving idea (yes, they received an award) that every maintenance man on the line did not need his own tool kit, that each shop could have a couple of sets for everyone to use. So, there was a mass turn in of wrenches, screwdrivers, sockets, etc to us in Supply. However, we could not declare them as serviceable item because they did not have plating, and needed to be sprayed with protectant to keep them from rusting. We tried to send them to Redistribution and Marketing (Surplus Sales), but they refused to take them because they looked serviceable. These were the early days of $800 hammers and $1200 toilet seats, and they were wary of trouble. Typical Catch-22, not serviceable, not unserviceable.
We were locked down during the October 1973 Israeli war, (flying missions over the Suez from New York and then South Carolina), we had 4 large (pallet sized) boxes of tools that were "Redistributed " to people in the wing. Problem solved. I am proud to have worked with the Blackbird, my part of it included keeping 70 lb and 140 lb rolls of film in refrigerated storage sorted by pull date, and getting up at 4 in the morning in our Operating Location to help put drip pans under the Aircraft after it had taken pictures of jungle.

Although they also increase the amount of false information out there, which is the risk, but the rewards have far surpassed the risks in that regard, even despite all the insanity with stuff like "fake news" and what not.

The SR-71 is my favorite aircraft ever built.
mine too
Yeah me too!
I prefer the A-12, just because no-one remembers it. And it was the precursor of the SR-71. The SR-71 just was a bit more developed version.

Agreed, hands down it's top 71 for me
This one and X-15!
My grandfather, James Plummer, got to fly in an SR-71B when he was Under Secretary of the Air Force. He remarked on his experience in a letter to me before he passed away: "...it was the smoothest flight I have ever made in any airplane. Even at the minimum turn radius permitted in the aircraft, there was no sensation of Gs or any other discomfort. Most spectacular, of course, was to sense the extremely high altitude where the sky is near black rather than blue and where cumulus clouds are in miniature. The only sensation of speed was watching the digital navigator tick of the miles, one every two seconds."
I mean if the minimum turn radius is the size of Texas I can see why he wouldn't feel any G's
Would you be willing to share such a letter?
@@bronsonpadmore3565 I believe he just did...
The SR-71 was limited to 2.5 Gs. Even a Cessna 150 can pull more.
Caden Howlett That is incredible. And to think, your grandfather flew this. This plane still looks futuristic. I would love to hear more pilots stories from this era.
When in middle school and high school I loved planes like the SR-71 but after going to school for mechanical engineering and learning how each of these individual parts work, I have so much more of an appreciation of what a work of utter genius this plane is. The question they always asked was, how can we get more. And no matter what the obstacles were that stood in the way, they still managed to find a way to make it work. Even more key, they were able to do it WITHOUT compromising their previous breakthroughs. THAT is what makes this such an incredible plane. There were no tradeoffs in the engineering. They somehow managed to make EVERYTHING work together. I will forever be enamored with this plane. It's just nuts.
If anyone wants to see an SR-71 in person, there’s one in the Dulles Air and Space Museum in Northern Virginia. It has a bunch of other aircraft, but the SR-71 is pretty much one of the highlights of the museum. It’s massive, and the lights at the bottom make it absolutely menacing. Definitely worth it in my opinion.
Also one on the Intrepid (Aircraft Carrier) Museum in NYC.
There's also at the Pima Air and Space Museum in Tucson, AZ. So very cool!
Museum of flight in Seattle
Also Evergreen aviation and space museum in Hillsboro Oregon. Bonus* there is also the spruce goose.

There were a lot of things we couldn't do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment.
It occurred when Walt and I were flying our final training sortie. We needed 100 hours in the jet to complete our training and attain Mission Ready status. Somewhere over Colorado we had passed the century mark. We had made the turn in Arizona and the jet was performing flawlessly. My gauges were wired in the front seat and we were starting to feel pretty good about ourselves, not only because we would soon be flying real missions but because we had gained a great deal of confidence in the plane in the past ten months. Ripping across the barren deserts 80,000 feet below us, I could already see the coast of California from the Arizona border. I was, finally, after many humbling months of simulators and study, ahead of the jet.
I was beginning to feel a bit sorry for Walter in the back seat. There he was, with no really good view of the incredible sights before us, tasked with monitoring four different radios. This was good practice for him for when we began flying real missions, when a priority transmission from headquarters could be vital. It had been difficult, too, for me to relinquish control of the radios, as during my entire flying career I had controlled my own transmissions. But it was part of the division of duties in this plane and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. Walt was so good at many things, but he couldn't match my expertise at sounding smooth on the radios, a skill that had been honed sharply with years in fighter squadrons where the slightest radio miscue was grounds for beheading. He understood that and allowed me that luxury.
Just to get a sense of what Walt had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Los Angeles Center, far below us, controlling daily traffic in their sector. While they had us on their scope (albeit briefly), we were in uncontrolled airspace and normally would not talk to them unless we needed to descend into their airspace.
We listened as the shaky voice of a lone Cessna pilot asked Center for a readout of his ground speed. Center replied: "November Charlie 175, I'm showing you at ninety knots on the ground."
Now the thing to understand about Center controllers, was that whether they were talking to a rookie pilot in a Cessna, or to Air Force One, they always spoke in the exact same, calm, deep, professional, tone that made one feel important. I referred to it as the " Houston Center voice." I have always felt that after years of seeing documentaries on this country's space program and listening to the calm and distinct voice of the Houston controllers, that all other controllers since then wanted to sound like that, and that they basically did. And it didn't matter what sector of the country we would be flying in, it always seemed like the same guy was talking. Over the years that tone of voice had become somewhat of a comforting sound to pilots everywhere. Conversely, over the years, pilots always wanted to ensure that, when transmitting, they sounded like Chuck Yeager, or at least like John Wayne. Better to die than sound bad on the radios.
Just moments after the Cessna's inquiry, a Twin Beech piped up on frequency, in a rather superior tone, asking for his ground speed. "I have you at one hundred and twenty-five knots of ground speed." Boy, I thought, the Beechcraft really must think he is dazzling his Cessna brethren. Then out of the blue, a navy F-18 pilot out of NAS Lemoore came up on frequency. You knew right away it was a Navy jock because he sounded very cool on the radios. "Center, Dusty 52 ground speed check". Before Center could reply, I'm thinking to myself, hey, Dusty 52 has a ground speed indicator in that million-dollar cockpit, so why is he asking Center for a readout? Then I got it, ol' Dusty here is making sure that every bug smasher from Mount Whitney to the Mojave knows what true speed is. He's the fastest dude in the valley today, and he just wants everyone to know how much fun he is having in his new Hornet. And the reply, always with that same, calm, voice, with more distinct alliteration than emotion: "Dusty 52, Center, we have you at 620 on the ground."
And I thought to myself, is this a ripe situation, or what? As my hand instinctively reached for the mic button, I had to remind myself that Walt was in control of the radios. Still, I thought, it must be done - in mere seconds we'll be out of the sector and the opportunity will be lost. That Hornet must die, and die now. I thought about all of our Sim training and how important it was that we developed well as a crew and knew that to jump in on the radios now would destroy the integrity of all that we had worked toward becoming. I was torn.
Somewhere, 13 miles above Arizona, there was a pilot screaming inside his space helmet. Then, I heard it. The click of the mic button from the back seat. That was the very moment that I knew Walter and I had become a crew. Very professionally, and with no emotion, Walter spoke: "Los Angeles Center, Aspen 20, can you give us a ground speed check?" There was no hesitation, and the replay came as if was an everyday request. "Aspen 20, I show you at one thousand eight hundred and forty-two knots, across the ground."
I think it was the forty-two knots that I liked the best, so accurate and proud was Center to deliver that information without hesitation, and you just knew he was smiling. But the precise point at which I knew that Walt and I were going to be really good friends for a long time was when he keyed the mic once again to say, in his most fighter-pilot-like voice: "Ah, Center, much thanks, we're showing closer to nineteen hundred on the money."
For a moment Walter was a god. And we finally heard a little crack in the armor of the Houston Center voice, when L.A.came back with, "Roger that Aspen, Your equipment is probably more accurate than ours. You boys have a good one."
It all had lasted for just moments, but in that short, memorable sprint across the southwest, the Navy had been flamed, all mortal airplanes on freq were forced to bow before the King of Speed, and more importantly, Walter and I had crossed the threshold of being a crew. A fine day's work. We never heard another transmission on that frequency all the way to the coast.
For just one day, it truly was fun being the fastest guys out there.
I really like this story

It's hard to believe how old this aircraft is now. Mind boggling! This was my favorite airplane growing up, and I had multiple models of it!
Engineers: How much fuel can you afford to burn?
Airforce: Yes

engineers; refer to prior answer
CIA: Yes
The SR-71 predecessor was actually an aircraft developed by the CIA. Surprised it wasn’t mentioned. Airforce planes piloted by CIA, not Airforce pilots.
I mean, when the plane costs a billion dollars, a couple bucks in extra gas doesn't really matter.
No, they were CIA planes.
It’s actually why lots of the SR-71 was so ramshackle.
They couldn’t design a brand new Mach 3 engine. They had to make one out of an engine designed for a flying boat. They had to figure out a starting system for it using a couple of Buick V8s because no existing APUs or air starters were powerful enough.
hi E W...
'
not important about currency to burn the fuel
This plane is such a technological marvel that it uses it's own fuel as a coolant
thats kinda normal for high performance jets
This isn't unusual for Jet aircraft. The Challenger 300 for example has multiple Fuel/Oil heat exchangers, and Hydraulic/Fuel heat exchangers. The Hydraulic lines are simply routed INSIDE then out the fuel tank which dissipates some of the heat of the Skydrol Hydraulic fluid which is under very high pressure
Jet-A used in normal day to day jets fuel also isnt special really. Glorified Diesel. You can absolutely run Jet-A in your Diesel car or truck.
A marvel? This is more like a miracle to you third-worlders! lol.
@@skiebroth2462 at least in the third world, we don't pretend to be a know it all smartass when we don't understand something. A trait that you should consider to integrate to your annoying self
Probably my favorite plane. The SR-71 Blackbird and the A-10 Warthog. I know that they're on the opposite ends of the spectrum in just about every way, but they're both incredible places. The Blackbird designed around an engine, the Warthog designed around a gun.
totally agree with love for both.
The A-10 Thunderbolt II, F-22 Raptor, & SR-71 Blackbird. Top 3 in my list of favorite jets to date.
Same A-10 then SR71
Grandad was a P-47 Thunderbolt fighter pilot in WWII in the pacific theater. Passed away in ‘02, but man can I remember some of his stories…(miss you grandad❤) never did he think that his daughter (my mom) would marry a guy who was in flight school who would spend the next 25 some years flying none other than the A-10 Thunderbolt II, the Hog.
Upon retiring my dad was given one of the barrels from the Gau-8 Avenger Gatling gun mounted on a beautiful one-piece of solid mahogany for wall mounting. But being my dad, he had to one-up that; he had the barrel removed from its mount and had the entire thing custom-dipped into a vat of liquid chrome, both it and the unfired round he got with it.
Fast-forward to now and you go into his office adorned with all sorts of badass A-10 memorabilia and all of it kinda fades away at the sight of the barrel with its bullet both in flawless/fingerprintless, flawless shiny chrome. 🤤
Suffice it to say, the Warthog is very near n dear to me. But the SR-71 is, most definitely, solidified as a close runner-up.
_She is the uncontested absolute King of the Skies. And she only ever flew for the Red White N Blue_ ❤🫡🇺🇸
Why's it called a warthog? Looks more like a puma to me.
Titanium can be tough to work on but the stainless steel alloys can be a nightmare in the machine shop. Hastalloy, Inconel and the other wear resistant alloys work harden quite easily and will make you pull your hair out !! I just cant imagine working on this stuff back in the late fifties.

THIS is literally the reason why i want to know more about this plane.
My first thought when they retired this in the 90's was.... "What did they replace this with that we wont know about for 50 years?"
Satellites? Because it was satellites. Spy planes are still useful though. Satellites are predictable and if you are fast you can move things out of their sight quickly.
@@RealEngineering Keep in mind that they used the RQ-170 for a decade before it became publicly known in 2011.
@@RealEngineering So predictable I even managed to take a photo of one of them. Unfortunately, it isn't moch more than a bunch of blue pixels, I need better equipment :)
Mig-25s (and Mig-31) played a role as well. Although they are not as fast (Mig-25s can fly Mach 3 but it will cause severe engine damage), they can fly as high and close enough to potentially fire Mach 3+ AA missiles. At those speeds AA missile avoidance is impossible.
It is the same reason why XB-70 was cancelled. After U-2 shot down incident, US stopped all Soviet flyovers.
@@RealEngineering Well, at the time (1999) I was working inside 'The Beltway' (Metro Washington, D.C.). We were not government or military. According to the 'knowledgeable' among our group we (the US) had a vehicle that could get people "anywhere in the world within 90 minutes". That sounded like some sort of ballistic transport. I agree satellites can 'see' everywhere. But they cannot transport. Anyway, the conversations my fellow 'unknowledgeables' and I had on this topic have long stayed with me. I mean, they created the SR-71 in the 50's. Imagine what was created in the 90's that we still wont know about for some time?
The most amazing part is that it was designed on a drawing board with a rule slide. No fancy 3D modelling and simulations.
I was speaking with someone recently who used to design propellers for submarines. He was contracted once by the Swedish Navy because of a design flaw in one of their new subs, the prop was too noisy. I asked him how he figured out what the problem was and he told me with his slide rule!!!! I couldn't believe it, with computer technology this guy was still using s slide rule!

I see things like this all the time given the current situation with masks. (I'm talking about COVID-19 for all you future readers that will have forgotten about the Great Plague of 2020). People will walk around with their masks on their forehead or chin, until someone gets near them. Then they pull them down. After that person leaves their vicinity, they partially remove them and scratch their nose, rub their eyes, touch their mouth; having just touched all the stuff around them moments before.
But I don't know what's a bigger waste of time because I often see the following as well: Two people with masks on approach each other and begin to talk. After a moment of talking, they both remove their masks off their mouths so they can talk easier. Then as they leave their close proximity, they put their masks back on.
I don't think people understand how masks and gloves work.
@J B Yes, I was being completely sarcastic. Though it will be interesting to see how this plays out in future references to this time. I mean the entire world is dealing with this in one respect or another. I was at a auto dealership the other day and noticed that a family had just bought a car and having their picture taken next to it. They were wearing their masks around their chins and over their mouths but not their noses as you described. Before the photo I heard them mention to the car salesman to wait a moment while they put their masks on so they could remember the time when they bought their car during the pandemic.
This has been a life changing time for many people with the economy failing, jobs lost, families and friends separated, and lifestyles changed drastically in so many areas. Of course, it has devastated families with lives lost, and not to sound heartless, but that's life in general every year, but a plague? Certainly not on the scale of past plagues in history, and let's hope that continued stupidity with people ignoring common sense approaches to health does not allow this or any other pandemic to grow to that scale.

This is definitely my favorite aircraft in history. And I appreciate this video since it cleared a misinformation I had regarding the leaking fuel issue. In a previous documentary (cannot remember what it was called or where I've seen it) they said that the leaking fuel was by design.

@@RealEngineering Will definitely watch them all! I've even shared that one to my gramps!
Early on in development, the test pilots found out in the event of an unstarted engine that unstarting both engines and restarting them both at the same time was far safer than trying to restart the unstarted engine. So that eventually made into the engine management computer.
This plane turned really badly due to the risk of unstarting an engine. Standard procedure to dodge a missile was to climb and accelerate.
It couldn't outrun soviet missiles back then. Those could easily reach mach 4 already if launched from an already fast moving aircraft. But it flew so fast and so high the time between detection and scrambling interceptors meant it was already out of range by the time they could take off and climb for interception. Regarding SAMs, the tech at the time didn't allow for on-the-fly calculations of interception vectors, so instead they relied on radar pings, mening they would have to follow and then catch up to the SR for a kill. They ran out of fuel before they could catch it. By now, SAMs can detect and cut the corner to catch a Blackbird, making the plane tactically unwise to use. That's why the USAF retired it in 1998 with no plans for a replacement, until scramjet engines came along.
The soviet plane of choice for interception would be either the MiG-25 or the 31 after 1975. Those could sustain Mach 2.8 greatly sacrificing range or Mach 3.2 while the engines destroy themselves. One SR-71 pilot claims he reached Mach 3.5 flying away from one interceptor.
And speaking of the USSR, most of the Titanium for the SR-71 was purchased by CIA front companies in foreign countries from them.
Well, not 100% true as to why it was retired. Spy satelites are better(now, compared to back in 70-80) and cheaper in the long run to maintain. SR had to undergo full refit after flight due to damage those planes sustained on "normal basis" - like missing panels etc etc. JP7 awas also problematic - TEB is toxic and hard to handle, each flight == risk of running out of it.
So all in all, it was expensive gamble to operate.
And to think this design was made a concept in the 1950's. Those skunkwork engineers were badass.
my brother married the daughter of one of the skunkwork engineers. lady is crazy as a loon. she tried to burn her parents house down with them inside. i met her father only once. seemed like a really nice guy. he talked about the fuel tanks that would leak when the aircraft was on the ground and the science around their design. It was way above my head. when her parents died they left her with a nice tidy sum which she promptly blew thru. that was money he earned building that airplane.

When your plane is so dope that you use fuel for cooling
The Su-144 had the same cooling system and that plane was NOT dope
Pretty much every engine uses fuel for cooling. Look up power enrichment. The phase change of fuel from liquid to vapour is one of the best air conditioners, ever.
What you meant to say, is: "SR-71 - even it's fuel makes it somehow cooler"
A lot of planes use fuel for cooling think fuel oil heat exchanger
@@iliketopumpit :) yes, indeed, you are correct. And I believe a lot of liquid fuel rocket engines do that, too.
But still, the way I phrased it is technically correct AND cheesy, and I find it fun to put it this way.

As a former SR-71 pilot, and a professional keynote speaker, the question I'm most often asked is "How fast would that SR-71 fly?" I can be assured of hearing that question several times at any event I attend. It's an interesting question, given the aircraft's proclivity for speed, but there really isn't one number to give, as the jet would always give you a little more speed if you wanted it to. It was common to see 35 miles a minute. Because we flew a programmed Mach number on most missions, and never wanted to harm the plane in any way, we never let it run out to any limits of temperature or speed. Thus, each SR-71 pilot had his own individual “high” speed that he saw at some point on some mission. I saw mine over Libya when Khadafy fired two missiles my way, and max power was in order. Let’s just say that the plane truly loved speed and effortlessly took us to Mach numbers we hadn’t previously seen. So it was with great surprise, when at the end of one of my presentations, someone asked, “what was the slowest you ever flew the Blackbird?” This was a first. After giving it some thought, I was reminded of a story that I had never shared before, and relayed the following. I was flying the SR-71 out of RAF Mildenhall, England , with my back-seater, Walt Watson; we were returning from a mission over Europe and the Iron Curtain when we received a radio transmission from home base. As we scooted across Denmark in three minutes, we learned that a small RAF base in the English countryside had requested an SR-71 fly-past. The air cadet commander there was a former Blackbird pilot, and thought it would be a motivating moment for the young lads to see the mighty SR-71 perform a low approach. No problem, we were happy to do it. After a quick aerial refueling over the North Sea , we proceeded to find the small airfield. Walter had a myriad of sophisticated navigation equipment in the back seat, and began to vector me toward the field. Descending to subsonic speeds, we found ourselves over a densely wooded area in a slight haze. Like most former WWII British airfields, the one we were looking for had a small tower and little surrounding infrastructure. Walter told me we were close and that I should be able to see the field, but I saw nothing. Nothing but trees as far as I could see in the haze. We got a little lower, and I pulled the throttles back from 325 knots we were at. With the gear up, anything under 275 was just uncomfortable. Walt said we were practically over the field-yet; there was nothing in my windscreen. I banked the jet and started a gentle circling maneuver in hopes of picking up anything that looked like a field. Meanwhile, below, the cadet commander had taken the cadets up on the catwalk of the tower in order to get a prime view of the fly-past. It was a quiet, still day with no wind and partial gray overcast. Walter continued to give me indications that the field should be below us but in the overcast and haze, I couldn't see it.. The longer we continued to peer out the window and circle, the slower we got. With our power back, the awaiting cadets heard nothing. I must have had good instructors in my flying career, as something told me I better cross-check the gauges. As I noticed the airspeed indicator slide below 160 knots, my heart stopped and my adrenalin-filled left hand pushed two throttles full forward. At this point we weren't really flying, but were falling in a slight bank. Just at the moment that both afterburners lit with a thunderous roar of flame (and what a joyous feeling that was) the aircraft fell into full view of the shocked observers on the tower. Shattering the still quiet of that morning, they now had 107 feet of fire-breathing titanium in their face as the plane leveled and accelerated, in full burner, on the tower side of the infield, closer than expected, maintaining what could only be described as some sort of ultimate knife-edge pass. Quickly reaching the field boundary, we proceeded back to Mildenhall without incident. We didn't say a word for those next 14 minutes. After landing, our commander greeted us, and we were both certain he was reaching for our wings. Instead, he heartily shook our hands and said the commander had told him it was the greatest SR-71 fly-past he had ever seen, especially how we had surprised them with such a precise maneuver that could only be described as breathtaking. He said that some of the cadet’s hats were blown off and the sight of the plan form of the plane in full afterburner dropping right in front of them was unbelievable. Walt and I both understood the concept of “breathtaking” very well that morning, and sheepishly replied that they were just excited to see our low approach. As we retired to the equipment room to change from space suits to flight suits, we just sat there-we hadn't spoken a word since “the pass.” Finally, Walter looked at me and said, “One hundred fifty-six knots. What did you see?” Trying to find my voice, I stammered, “One hundred fifty-two.” We sat in silence for a moment. Then Walt said, “Don’t ever do that to me again!” And I never did. A year later, Walter and I were having lunch in the Mildenhall Officer’s club, and overheard an officer talking to some cadets about an SR-71 fly-past that he had seen one day. Of course, by now the story included kids falling off the tower and screaming as the heat of the jet singed their eyebrows. Noticing our HABU patches, as we stood there with lunch trays in our hands, he asked us to verify to the cadets that such a thing had occurred. Walt just shook his head and said, “It was probably just a routine low approach; they're pretty impressive in that plane.” Impressive indeed. Little did I realize after relaying this experience to my audience that day that it would become one of the most popular and most requested stories. It’s ironic that people are interested in how slow the world’s fastest jet can fly. Regardless of your speed, however, it’s always a good idea to keep that cross-check up…and keep your Mach up, too.As a former SR-71 pilot, and a professional keynote speaker, the question I'm most often asked is "How fast would that SR-71 fly?"

The fuel leak information isn't entirely accurate. The truth is no sealant was ever found that would work at all temperature ranges. Instead, realizing the expansion properties of titanium, the gaps that allowed the leaks were deliberately engineered into the design. So when the aircraft got to operating temperature, the leaks were sealed off mechanically. The sealant applied to limit the leaks only ever worked at ground temperatures and shortly after take off. By the end of each mission the sealant was mostly useless.
You are correct. As a maintenance airman on the SR in the late sixties, I got to experience the leaking fuel and resulting drip pans for four years. Loved it.
That's also the reason for the grooves in the wings which you can see at 8:51. Thermal expansion could cause the wings to bend but instead now the grooves just get a little deeper and the wings remains straight.
Larry Fry did you work at Area 51?
Something else caught my eye, the leak table, showing Zone 15, Dry Bay areas, 950 cc/Minute/Side. That seems unbelievable. By my calcs, that 950cc is 1/4 Gallon.

For my money, this aircraft represents a greater achievement than even the actual space program. Or at least equals it. The ability to fly in so many different regimes of flight is astonishing. The absolute controllability of all systems from idle speeds to ramjet mach 3+ speeds in everything from sea level air to very nearly not any air at the top of the atmosphere is just incredible.
It's a classic engineering understatement to refer to Unstarting as "a sudden yaw". Pilots were knocked unconscious several times. The "solution" was to detect the unstart and snuff the other engine. Pilots reawaken in the world's largest lawn dart on a course to slam into the ground at mach 2-3. Fortunately, they were starting from such a high altitude that there was time before impact to restart the engines and start aviating again. Compared to the risk of the aircraft killing you in a flat spin, Soviet missiles were not seen as dangerous.
Exactly, not a sudden yaw. But a violent shaking that caused pilots head to hit the cockpit windows and walls... Not a really nice behavior

Hey, I know, let's end a few more myths about the SR-71. I was in ECM, was trained by SAC to work them so, in a pinch, I could be moved TDY to work them, and had friends who did work them. First, from what we were taught in 1972, the shape of the SR-71 was not just for speed. Contrary to what you have been taught about the FB-117, the SR-71 was the first plane to use shape for stealth. The U-2 was the first to use radar absorbing paint and materials for stealth. We could tell when the Ruskies were tracking an SR-71 because they would say something to the effect that eagles don't normally fly that fast because that is how big an SR-71 was on their scopes, which, if you are familiar with radar scopes, that alone would make them difficult to see. Imagine trying to track something on your radar scope that is the size of an eagle and traveling at Mach 3+. Just a wee bit difficult. Then, when you add in the ECM, which masked an already small picture on the scope, it was almost impossible to see. Plus the thing flew so fast that, if they entered the range of the scope just behind the radar sweep (I know this from talking to radar weenies) the plane could fly cross a significant part of the scope and out of range before the radar sweep could get back around and see the bird making it even harder to see. The way the Ruskies ended up having to track an SR-71 was to see it on one radar scope and tell another radar further down range the time, location, direction, and altitude of their siting and the next one or two radar units would note when they saw the bird, time how long it took to get there, and then have to calculate the speed of the plane for a guess shot with a missile. It was ye ole poke and hope. The bird was significantly faster than they tell you. They only tell you the "declassified" top speed not its actual top speed. That is still classified.
That's really cool! By the way, what do ECM and SAC stand for?

"One day, high above Arizona, we were monitoring radio traffic pf all the airplanes below us.

I wanted to subscibe for the second time
I’m sure that many of the UFO sightings back in the 60’s and 70’s were due to top secret flight testing of planes such as this. Even today to see one roll out it looks like something state of the art for today. Actually it looks futuristic still. I can’t imagine what people thought about it if they saw it in the 60’s, not knowing that it even existed yet.
It amazes me how advanced planes like this were built in such a short time period. I mean in 1945 99% of airplanes were slow lumbering piston engined airplanes. True, by the end of the war there were some very early turbojet fighters around that proved the concept and demonstrated the speeds that could be achieved. But the thrust was small and the failure rate was very high, with those surviving having very short overhaul periods. In a little over 15 years, engineers went from very few unreliable turbojets, to the incredibly reliable and incredibly complicated turbojets on the SR-71.
And not only that plane but the Concorde as well. The only thing that made Concorde possible as a long range passenger jet was the fact that it could fly at Mach 2 without afterburner. Afterburner was used during takeoff, then was turned off during the noise abatement procedure. Then once they were over open ocean they would go to full throttle and turn the afterburners back on and leave them on until they made it to around Mach 1.7 I believe. Then they would leave the throttles at full, but shut off the switches to the afterburners. The Soviet supersonic passenger jet couldn’t be flown supersonically without the afterburners on all the time, greatly reducing the range.
The engineers took a different route on Concorde. They installed a series of movable doors on the intake nacelle for each engine. Those doors were controlled by two computers for each engine, one being a backup. When supersonic, the doors would move to a position that would slow the incoming air to around 500mph, where the turbojet could use it and still generate adequate thrust. It amazes me that engineers in the 60’s designed these two advanced aircraft when only 2 decades earlier jets didn’t even exist in significant numbers. The sr-71 and the Concorde both look like they could be rolled out the door today and accepted as modern state of the art aircraft. Of course us and the Soviets were going into space during this time as well. It sure was a time of major technological advances and lots of major achievements.
I swear that knowing that they made this absolute beast of a machine in the damn 60s makes me wonder even more what they have right now

I personally found the fuel storage part the most interesting. Always thought it would be in a long tank and insulated to keep it away from the scorching exterior when up to speed. Never would have guessed that it WAS the insulation for the plane's components.
Getting fuel hot isn't a problem because fuel by itself doesn't burn. As long as you don't allow oxygen in the tank and you have pressure valves it doesn't matter what temperature the fuel gets. Something like what happened with TWA 800 happened because there was oxygen in the tank.
I don't know if the SR-71 had a nitrogen gas system or if they just didn't let the tank run dry. Liquid fuel doesn't burn, it's vapor that does and only within a certain ratio. The only time you have a risk of explosion is if you let the tank run dry.

If the US gov built this in the 60's just imagine what they have built since.
Sadly not much lol. F-35?
@@nicksalvatore5717 do we need this though? With how high fidelity satellites are and how much more cost effective drones are I don't know if it makes sense to design something like the SR 71.
Imagine if the US built it during the 1930s
@@danaolsongaming exactly... when this was developed, that sort of capability was unheard of at the time. Just think of things that are unheard of at this point in time... that's what they're developing. Things you can't comprehend in this point in time.
German engineering!
I still can't get over the fact that they designed a plane with an engine that proved to be *too powerful* for the airframe even when they specifically used the best materials available to them, forcing them to cap the engine to a much lower level of power than it's actual maximum.
“Skunkworks” is such a good read. SR71 is easily my favorite aircraft. Great video!
I could not agree more! Amazing book!
Yes! Was looking for this comment! Fantastic book - audible has an excellent audiobook version.
That transition to the commercial in the end is so smooth
Kelly had a great team. With Kelly at the helm, they created the most impressive aircraft to ever fly the skies, still the world's fastest air breathing engine powered to this day! And she's been decommissioned since the 90s I believe
Good video. My grandfather was an engineer for the skunkworks. He was a big part of that engine.
The range of the SR-71 was limited to approximately 11.5 hours, by the amount of liquid nitrogen stored in its dewars, used to inert and pressurize the fuel tanks. The inlet system was designed by Ben Rich and his small team. He was awarded the American Institute of Aeronautics and Astronautics Award in 1972 for designing the Blackbird's propulsion system. The SR-71 had "tactical limits" of Mach 3.35 with a maximum Compressor Inlet Temperature of 427 C. In addition to the air, by-passing the engine to the afterburner for additional cooling and thrust, the front of the inlet, with its associated doors and spike, provided an inlet duct pressure of 18 psi, while the outside air pressure at 82,000 ft. was only 0.4 psi. This large pressure differential provided a forward thrust vector, pushing on the back of the spike and providing 54 % of the total thrust, while 29 % was produced by the ejector, and only 17 % by the engine. The speed of the SR-71 was limited by thermal temperatures, recoveries from "unstarts", and the shock wave, coming off its nose, entering the inlets, creating "unstarts." Above 3.35 Mach, there was a high probability that the aircraft would be unable to recover, if an "unstart" occurred.
I had thought that triethylborane was the primary limitation on the max number of mid-air refuelings. I didn't know about the nitrogen tanks; thank you!
@@justinhannan1713 The SR-71 had 16 "shots" of TEB (Triethylborane) per engine, which was more than enough to accomplish its missions, regardless of their duration, 1 shot to start each engine, leaving the remaining TEB to relight its afterburners after refuelings or, in the event of a flameout, to restart the engine.
