Imagine the silence after hearing that engine running for over 2 months.
Loud silence
That makes me really uncomfortable for some reason...

IIAndersII they probably had earprotection or what ever it means in english
What silence? Don't you hear that weak engine? We should land in four more days

Yup
But you gotta admit 64 days and 22 hours was pretty close to 65
Minecraft, Nintendos, number of unique values with 6-bit binary, and now flight duration (in days).
A stack of days.
I bet after they landed they still heard and felt the vibration and engine noise for a few days, the quiet would be hard at first.
Vets with PTSD sometimes say that you tune out the noise not matter how deafening it is but the loudest moment is when it stops
I used to come home and hear the conveyer belts from the job i had at the time running while i was trying to fall asleep
I sometimes go to my parents home 300km away, in my motorcycle.
After I stop, I'll feel like my entire body is vibrating and my fingers curl up to the shape of handlebar.
If I lie down in bed, I can feel the bed slowly bobbing left and right.
And if I close my eyes, I suddenly wake up feeling like I went off the road.
And 300km isn't even very far...
@@phs125 Yep, I rode over 1,000mi (1600km) in a few days on a crotch rocket (bad for long distance) and never had this problem. I did flatten one side of the soft tires from leaning into the wind, so coming back through the mountains was scrary. It'd get really squirrely in the curves to the point I couldn't even keep up with a Harley (my friends bike).

@@jordanabendroth5568 hmm I wonder how much a c47 is if I bought one that wasn't used for civilian use.
@@jordanabendroth5568 i'm pretty sure a plane with a fuckton of flight hours is going to be worth less than one with just a few flight hours
A piston engine with thousands of trouble-free, perfectly-documented hours is WAY more desirable than a brand new engine of the same type, because new engines of the same type are (intentionally) outrageously expensive and there's no way of knowing if they have any defects that will show up later.
Obviously with thousands of hours on it, that Continental 145hp engine would need to be cleaned, overhauled and rebuilt, but that's obligatory for aircraft engines per FAA regulations anyway. It's not like cars where the engines are disposable.

In the event of alternator/generator failure, cabin heating would remain unaffected because it is a mechanical system that pulls heat off of an exhaust shroud and into the cabin... just a note
And directed there by means of a fan one would presume
@Tefans97 no fan needed. The aircraft's front cowling has inlets for incoming air. Using a system of tubing that runs from this area to an exhaust shroud and then to the cockpit provides an efficient means of heating.

Don't waste time scrolling down, it's literally just people complaining about how he didn't use the metric system
Ariq Rashid just give me a oz of meth and I'll break the record lol
It is kinda annoying to anybody that isn't from the US. Non-Metric is outdated. People need to move on, and not be stubborn.
Pro-metric people are pompous.
An 18th Century survey crew measured a portion of the Earth's surface (if I recall, one member of the crew died in this farcical accomplishment) in order to derive the length of the meter (metre, if you're both pompous and British), which is about 3.37 inches longer than our familiar three-foot-long yard.
Yes. Quite an accomplishment.
"The metre is defined as the length of the path travelled by light in a vacuum in 1/299 792 458 seconds.
"The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. In 1799, it was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. In 1983, the current definition was adopted." (Wikipedia)
The original definition of the meter (as mentioned above) is a reflection of the fantasy at the time that it was important that the new system be defined in terms of the planet upon which we live (Earth worship). It was a rejection of the notion that the derivation of a unit of measure should be the length of a bodily member of the King of England, whether it be a foot, or the length of one of his finger segments. This might today be called xenophobia on the part of the Continental Europeans. Except that the idea that the metric system is vastly superior to the standard system has reached something close to a universally religious fervor, that particular belief approaching that of the idea that an airplane wing derives its lift in accordance with the Bernoulli principle.
I never read about this: "No. Don't send us any equipment measured in inches. The occupying Germans must be shot with metric bullets. Take away those tons of artillery rounds from our shores. We insist on kilograms, you fools."
The worship of the metric system is a strange phenomenon, when it is taken into consideration that most people in the "metric countries" don't access the system at any level closer than a kilogram of butter, or kilograms per square centimeter of tire pressure. "But, it is a decimal system," which alone makes it worth of worship.
Okay. It is a decimal system. Hooray. You win.
.
LONG LIVE THE IMPERIAL/STANDARD MEASURE SYSTEM! Sadly we Aussies surrendered to the metric system in the 70s, though I still say miles, feet, and other units of imperial measurement in day-to-day conversation. Bloody Froggie and Pommie wogs and their horrid metrics down the world's throat, save for the Septics of course.
Metric is the new 'Standard'. Imperial sucks. Get over it. Seeing a drawing with simple measurements down to whole or 0.1mm increments of a Millimetre is rather easy to read. Which many do. If you know you do need a specific dimension tighter than 0.1mm you know it's for a good reason. Otherwise make the dimension rounded up, for clarity. It's close enough. Can't do that with an Inch, too large. Many American drawing are always using Fractions, so they are always using needless decimals. Is '.1875 IN' really that far off from '.2 IN' Use that instead. Another thing that's easy to follow is Drill sizes. MM is straightforward and you don't have to get a damn chart to know wtf is a "B" drill or "#27". Fuck that guy for coming up with that.

I didn’t know Cessna 172s had a full-functioning autopilot back in the ‘50s!
It's a long reach to even call it an autopilot, much less full-functioning. It's a simple two-servo device for holding heading and altitude.

@@imluvinyourmum no, i say 10 kilometers
And then why was there this NASA accident, because Boeing decided to use the imperial system when everyone agreed to use the metric system? 🤔
Even so, i honestly don't care what system they're using, as long as they put it together and it works in the end. Would just be more intuitive to use the metric system ^^
@CheatyTycoon 2 No, if I get a contract to build a 50 meter long ship, then build a 50 feet long ship, its my fault. You always build what the contractor wants, so if the contractor wants his software to use the Dublin Spire as the system of measurement, then he gets his software with Dublin Spires as the unit of measurement. Oh, and you know, the reason why the metric system is superior, is that metre means everywhere in the world roughly the same, while your inch is in germany elle and in french pouce. So yea all countries just say metro meter or métre.

Side note, the cabin heat for a C172 is mechanical in nature. If the alternator failed, it wouldn’t effect the cabin heat at all.
Anyways. This record and the execution of it is absolutely awesome.
They said generator, and given the time frame involved it probably was a generator. You are correct on the heat system, which works just like an old VW Bug.
@@davidedmundson8402 You’re correct. It was a generator back then instead of alternator. I’m still trying to figure out why the heat failed. I’ve talked to Mr. Cook’s son on the phone. Their heat definitely stopped working. That would have been miserable. Not to mention having to hand fly 24/7 after the autopilot took a dump due to the generator failure. The two pilots were incredible.
Two issues I have with this as a Cessna 172 pilot. First, he said a hose or line was connected from a truck to the fuel tanks/engine to refuel the aircraft. A C172 is gravity fed meaning the avgas in the tanks uses gravity to go down into the engine (oversimplified), unless they used a pump and some interesting engineering it would not be possible to get fuel from ground level into the engine. Without the refuelling, a C172 with the extra tank can only fly for just under 3 days (assuming the mixture was perfected leaned). The other smaller issue is when he said the generator failed... a C172 doesn't have a generator, it has a battery and engine which works very similar to a car. If the engine was running it would be supplying the battery with power thus, like a car the electrics would be fine, there was no mention that the battery had a technical issue. Even if the battery charge supply fail (which the gauge would indicate), depending on the exact conditions they would have around 20 minutes of electricity and no time if the battery itself failed. In this case, the pilots would be making an urgent landing and they wouldn't be able to keep flying for days on end.
I'm not in denial that this happen, I just think a lot of key elements of this story haven't been told.
I’d love to see their logbook entry!!!
Just buy a Boeing 747 and fill all the compartments with fuel spare parts and get some on air mechanics and your good to go
Have fun flying that thing close to ground to refuel
@@heinrichmirgrautsvordir6613 you’d have in air refuelling. Airforce one can stay in the air for a stupid amount of time. I’m pretty sure it’s something like 28 days. Until it runs out of food.

The engine in a 172 is normally rated to go 1800 hours between overhauls, so it was nearing the end of it's rated service life. Another fun fact is that the 172 came out in 1956, so the plane was only 2 years old when this was done. New ones are available today, but not as cheap as they were back then. It will run you $486,000 to get the newest model, which isn't much different from a 1958 except for the addition of a rear window, avionics and the added liability insurance Cessna carries on each plane it sells in case of a crash (about $100,000 of the total cost). I would guess that the price for this plane when new in 1956 was probably around $9000.

Btw for those wondering the avg cessna 172 flys and cruises about 2300rpm (rotations of the crankshaft per min) so
2300rpm X 60 min an hour X 24 hours a day X 64 days = 211,968,000 rotations before the engine had trouble
Generator has absolutely nothing to do with heat
Doesn't the 172 use the engine oil for heat?
yegfreethinker no, it uses an air to air heat exchanger. It’s commonly called a heater muff or shroud among other names. This is a metal tube or box that surrounds an exhaust pipe. It has an opening for fresh air from the outside which is heated by the exhaust pipe (there is no mixing with the exhaust gases) and an outlet for cabin heat and carb heat.
They need electrics to function to actually turn the heater on
So I can only imagine the stench from reliving themselves in cups must have been overwhelming.🤢
probably not
Out the window!!
If you have been inside of that thing for some time it would have no smell because your nose will be accustomed to it.

Dang, i wanted to know what happened to the plane after. Like how bad the engine was and it’s overall condition etc.
I don’t know. It’s hanging up in McCarran. Why don’t you look?
Seriously though... it made it past its regular TBO and didn’t have the challenges most aircraft engines have of cold starts and years of neglect. The inside was probably pretty shiny.
And really, on a normal overhaul all they do it measure everything and if it’s within service limits it gets thrown back in. Only the main and conrod bearing shells as well as consumable hardware are replaced.
But based on experience... the spark plugs would likely be very worn and fouled, the magneto breaker points would be very pitted and burned, and there would be quite a lot of carbon plus more than a bit of metal in the oil screen, the cylinder interiors would be relatively carbon free given their continuous operation at high RPM and temperature, and the exhaust valves would be fairly eroded and probably starting to leak and hot spot.
Thank you random stranger
Salute to his transition from vid to sponsors
The main problem here was carbon clogging the engine. Would there be a way around this? I can think of 2:
1) Hydrogen. Hydrogen produces no soot, and therefore would not clog the engine. It's not perfect though, as the engine will still wear.
2) Swapout. If instead of flying the C-172, someone flies the C-337 Skymaster, then with a lot of modification it could be possible to swap an engine out mid-air.
If the plane is modified so that an engine can be completely isolated from the rest of the plane (Fuel lines closed and severed, wires seperated, etc) then it would be possible to remove it. This could range from a complicated thing where is is pulled out by another plane, to simply dropping it and having a parachute.
After seperation, another plane can fly alongside with another engine. With some modification, the second plane may even be able to dock, but I haven't looked into this and it sounds like a bad idea.
The second plane would be carrying an extra engine, to be lowered either out the window or out a hole in the floor. Using either magnets or wing-walking, the engine could be guided into place and secured. It would then be further secured by stuff inside the plane, and fuel/hydraulics/wires can be re-connected, and then re-start the engine!
The C-337 would be perfect for this, as it has two engines and can therefore still fly during an engine swap-out (Although if wing-walking is involved you'd have to be extra careful while swapping the front one. I'm thinking two securing points, one on the plane and one on a deflector rail, which would deflect someone away from the rear propeller if they fell, so they can deploy an emergency parachute.
It also has centre-line thrust with a failed (Or switched off) engine, so there wouldn't be any yaw during the swap-over.
This would probably be kinda dangerous, but with a few automated alerts, good pilots, and safety systems, it should be possible.
That's an insane idea and if you get the money to do that one day go on ahead
