Hey, Ive listened to the feedback. Ive deleted the duplicate sponsorship segments and kept the main one. Ive also put a timestamp in the description so its easy to navigate the sponsor chapter. Thanks for the feedback.
@@waterlinestoriesat the part where you mentioned “here is a video about the 500 million dollar treasure” I don’t see any video link. Could you please share it in the description or comments?
"Needlessly prioritizes passenger safety over commercial innovation". Yeah, that's a sentence I never EVER want someone conducting a high-risk operation I'm a part of to say.
You have to wonder if people actually hear themselves when they say things like that. If everyone was sane, every quote like that would end with some version of "Wait, that came out wrong"
Stockton Rush didn't have some "disruptive" new technology, like he pretended. He was just willing to use a suboptimal hull shape, eat into safety margins with standard parts, use inexperienced designers (e.g. College students), and gamble his life/the lives of his passengers on using carbon fiber as the hull material, all in order to save on costs/maximize profits. If anything, this incident just shows why properly designed, tested, and certified deep sea submersibles are so expensive.
Additionally, it shows why capitalism has ultimately failed the human race. The reason for all of Rushs mind bogglingly stupid and evil choices were driven /solely/ by capital motives.
well, it's not really that the idea couldn't be of use. it's just that it might end up being really expensive to use properly(rebuild amounts) and nobodys properly tested the idea really (beyond that it does work a couple of times, which actually could be enough for some use cases, but now we wont know for a long while). you need to test everything else regardless of what you're building it out of anyway and if you'd use it for commercial you would need to devise a way to test(xray etc) or have a replacement program for the parts based on the testing same as for airplanes - and you'd need the money to do the destructive testing to be able to record the signs what the checking program would look for. doing it out of steel gets really expensive as well and would need the same program (it can also be inaccessible due to that sourcing the right alloys can end up way more complicated than one would think at fist.. politics getting involved kind of complicated).
The fired engineer said he was a member of bohemian Grove. Being a money hungry death cult member I'm not at all surprised he had a death wish for himself and any high paying passengers.
When I was a kid a friend and I drew up a set of plans to turn a old propane tank into a submersible, and we were going to charge other kids to ride to the bottom of a old strip mine water pit. We lost the plans and never built it. Now I know who stole the plans.
i’m an FE engineer and i can guarantee you that this topic will be a case study for future engineering courses in the dangers of DIY and not considering why the regulations are in place. brilliant video, cohesive and well explained, and absolutely worth a good watch. thanks for making this - slides included. good reference. when i TA a statics and dynamics course next year, this video will be one I show to the class.
As long as Rush was only endangering himself, power to him, he can do whatever he wants. But the fact that he was allowed to kill four other people through his willful negligence is an absolute crime.
I agree 100%. It's disgusting the danger he put these otherwise people in. Yeah they have some accountability in it also, but they trusted someone that was considered a professional in his field. He totally manipulated them.
@@nathansmith1085 If they did the level of research that you needed to even think to go that deep into the ocean they would know 100% that Rush was delusional. Hell, they signed a waver that mentioned dying 3 times and that the vessel was experimental.
@@dbapto6994 i won't lie, I've actually been watching videos on YT lately. Fudge that. Pretty awesome to watch. Terrifying tho. Dumb things like black holes. 😂
I am surprised at how many content creators continue to praise Rush and refer to the outcome as some unfortunate event as if there was no negligence. This was entirely foreseeable, let's not forget that Ocean Gate knew the vessel would not pass regulation and testing, therefore they chose not to get the Titan certified for this very reason. Furthermore, the most egregious act being the termination of engineer for trying to alert Rush and Ocean Gate that the vessel was not safe. Rather than addressing these concerns he fires him for speaking up. This is no accident, this is the result of a truly negligent CEO who ignored and silenced sound engineering advice, deliberately avoided certification and 4 innocent people lost their lives.
Not to mention he was too cheap to get a ship that could actually transport it on board instead of dragging it through the ocean on a raft behind it. That’s a huge red flag to me in itself.
I just want to correct you on a relatively minor point. The controller used for the submersible, while Playstation patterned, is actually from Logitech.
@@subduedreader5627 It's not only wireless, it is also connected to a PC with a Windows OS instead of a Realtime-Computer with a Realtime OS or an SPS.
@@Blakbox92Game controllers are actually pretty standard for this kind of thing, which makes sense, they're designed to be intuitive and efficient. The military uses them for all kinds of stuff. Pretty sure they don't go wireless third party though. I wouldn't even rely on that for gaming, much less my life.
The controller choice while frugal, was unlikely to ever cause anyone to die! The poorly designed and insufficiently tested hull is (was!) the problem, forget the stupid controller as it really was not that big of a deal, it didnt cause the hull to implode and that's what killed the people.
@@Lawyerboyleslie72Foolish for believing him. If someone told me he could take me and other passengers to the Moon and said things like:"Safety stifles commercial innovation." I'd told him to get lost. Btw, there are plenty of really fast kitcars and glorified tuners. Fools with more money than sense purchase these death traps and up crashing. Getting a supercar to reach 400km/h (250mph) is relatively easy. Getting to that speed SAFELY is a whole lot more difficult. Hence why the properly engineered supercars needed many years of research and testing using the best materials and the death trap kitcars and glorified tuners do it the way Stockton Rush did it - by cutting corners. You don't have to be a rocket scientist yourself to understand this.
@@Lawyerboyleslie72 two of them knew what they were getting into. the other two are the biggest tragedy here, but they could've looked into what they were getting into before going, i suppose. though who would think that these other three men were going there knowingly with their lives on the line?
I think if, when you pay to go on an expedition, and you have to be described as a 'Mission Specialist' then it's on You if you don't hear those 'Alarm Bells' ringing. 🙁
Truly unbelievable the level of ignorance Rush had. He was given so many warnings ,even fires his engineer for pointing out major issues, yet he knew better. This man was an idiot who got 4 people killed because of ego. What a legacy.
About the US Navy not disclosing that they had recorded the sound of an implosion: they didn't because they recorded it through the SOSUS system, and everything that is recorded through SOSUS is classified, because it could reveal how the system works and thus jeopardize its effectiveness in monitoring submarine activity off the coasts of the United States at SLBM range.
That's not true. Sossus hasn't been secret for over 35 years. Every aspect of sossus is public information It's regularly used for biologist to listen to whales, vocanologists to listen to underwater volcanic explosions, and 14 different scientific endevours.
Josh Gates, from the television show Expedition Unknown, was actually supposed to be on the Titan. For safety his teams dive specialist tested it first. Went down about a hundred feet, before he declared it not safe and returned to the surface.
One thing about Stockton Rush is he honestly believed that those safety protocols were just BS, even though most all of those procedures are written in blood and are lessons learned from other accidents. He put his life on the line along with others and paid the ultimate price.
Indeed, i work in electricity and ppl always look at safety regs are there to piss you off. Ive seen people get hurt, maimed and killed by taking shortcuts. I agree the safety should look like blood to get the point across something horrible happened for it to put there. I had my job threatened for refusing to due a hot pull of 220 triplex w a super neutral towards a hot bus bar in gear room. The bar? 4300 amps!!!! If half a amp killes that creamates you. The safety a piece of ply wood and boards to stand on. To clarify the bars were around 2 or 3 feet from where mg crew would be
One important thing to note, some experts agree that the sensors were a gimmick. There was no testing confirming that they would work or even provide enough time to do anything.
I explained it in more detail in my comment, but essentially the time between "sensors warning you" and "catastrophic failure" is in the seconds to milliseconds range. Enough to inform you of your imminent death, not enough for you to do anything about it.
@@cremebrulee4759He probably gave them too much credit, it hard to believe that people are that stupid even with the evidence so his brain was probably shorting out whenever he read that particular piece of "genius".
@@devilsadvocate1380 He just made an error, dude. Gave them too much credit? This is just a fact; you can't look up their terrible design and then lie about. You are calling him a liar now, instead of him just making an honest mistake
In the construction videos it looks like they are wrapping the cf around a titanium tube, but that is just a mandrill for shaping the final product and is removed once finished.
I have done some seriously dangerous jobs in my time, all with their unique ways of ending up as a thin veneer across the work area... But man, just the thought of working as a saturation diver is enough to give me nightmares.
I'm starting a company, PlaneGate and going to design a Plane out of light concrete and make the wings on the inside but the passengers (Pilots) have to sit on the wings to save costs. Then I would like an investigation into why it failed. Thank you. Tickets on sale now.
@@Lawyerboyleslie72 What do you mean. You can't prevent people from killing themselves... but you can call them out on their BS instead of collecting the check in silence.
@@Lawyerboyleslie72the engineer? ultimately he failed to prevent anything. however he stuck with his morals when it came to the safety standards and stood for them all the way to court. most people would have caved once they got sued
Man saw the Deepsea Challenger and went 'I'm going to make the Temu version of that' and then got angry when people told him it's not okay to expose people to the dangers of going underwater in a Temu Challenger. This will never not the funniest thing ever.
perfect analogy. Also, they missed 1/2 the story the middle & the final conclusion. From Inception to implosion was the deception & corrosion that led to the implosion
I find it hard to say that the completed missions were a success. It’s like saying that crossing the road without looking & not getting hit was a success. No body expects to be hit by a car every time they cross the road without looking side to side, you just don’t expect to last very long on this earth if you keep it up.
This is the third minor thing that has been pointed out. The fuck kind of research is this dude doing. A technical or engineering mistake i can understand but how do you get which ocean the most famous shipwreck in history wrong? Smh
One quibble I have is that the US Navy's SOSUS network is actually **extremely** good at localizing the origin points of sufficiently loud sounds such as implosions. This was ably demonstrated with a number of lost submarines during the Cold War.
Indeed. It was and is highly useful at not just detecting the sounds but finding where they came from. Without SOSUS, it would have taken far longer than a couple of months to find where Thresher and Scorpion went, as well as other incidents.
I came here to say the same thing. They knew within minutes of the implosion. I do believe the navys explanation of why they waited is just a cover to hide the full capabilities of the system.
i think it's obvious that they knew where it imploded. as soon as they got the equipment, they went straight there. the "search" before that was nonsensical, though, and not disclosing the information about hearing the implosion.
@@nikoscosmos I think it's used in cars for weight loss, not to provide survival-ability when the car hits a brick wall. You can have carbon fiber spoiler and car body, but the cage that protects the driver is still made of alloy of sorts.
@@nikoscosmos the pressure there is a sharp tension pressure, that is, longitudinal to the fibers... cars or airplanes rarely require withstanding pressure vectors perpendicular to the fiber structure (where your only carrying strength is the binding epoxy), the exception is carbon fiber wings, but even there, they can use elasticity transferring the fiber strength that way to compensate for it (why you get so much movement in a 787 wing)... you cannot do it with pressure.
@@nikoscosmosThe carbon fiber in cars isn't to prevent the cars from crumpling. Besides, crumpling is what you want in a crash. Crumpling, rolling, and shedding displaces the energy away from the driver (and passenger, where applicable). That's why NASCAR wrecks are so fantastical most of the time, and drivers still walk away with little to no injuries. When NASCAR drivers DO get hurt, it's in wrecks that usually don't look flashy. The wreck that killed Dale Earnhardt was super simple. No rolling, no major crumpling, little if any shedding... Just a smack into the wall, and he was finished. If carbon fiber prevented crumpling, race cars wouldn't use it because it would make the cars more dangerous.
32:17 See, I don't agree with that. If you look at the stress-strain curve for carbon fiber, there's no warning whatsoever before failure. The yield point is the failure point. I know they heard noises when the hull was new but that is probably just weaker fibers breaking. Even the Engineer who was allegedly fired for refusing to rubber stamp the design said the same thing about the amount of warning you'd get.
It was NEVER evacuated to get rid of air it was SUPPOSED to be 7 inches thick, I was made from rejected aircraft carbon fibre, Case closed he would have been convicted for corporate manslaughter BUT who has the jurisdiction
Honestly, I know there's been a ton of coverage on this but I've really been waiting for you to do it! You always have such an interesting and educated take on things
Exactly, most others focus on a "gist" or "feeling" about events. This is not that. That acrylic window was tested to 1,300 meters. And then Rush just took it to 4,000 meters over and over crossing his fingers. Same with non destructive testing of the pressure vessel, it's expensive but subjecting a carbon-fiber pressure vessel to repeated cycles of compression and decompression before analyzing the microscopic changes...Simply has to be done before sinking it to the bottom of the sea many times, with many lives on board. Excellent video.
I think of the simplest examples is putting that limiting factor, deep sea challenger, and titan next to each other. You can see what serious professionals do, and what an amateur out of his depth has done. It's a stark difference. I wouldn't be so upset of this guy trying something new and innovative. But doing it at the cost of others lives is just beyond reckless.
There is nothing 'innovative' about recklessness. Sidestepping accepted protocols to get to the cookie jar first isn't new, and it always ends badly. It's what jackasses do, and jackasses will always be with us. The trick is to recognize them for what they are before they can cause irreparable damage. And 'innovation', whatever that golden calf is, is not a substitute for sound engineering analysis regardless of what nontechnical folks would prefer to believe. In a different age Stockton Rush would be selling patent medicines off the back of a horse drawn cart.
A year and some change after this, I'm sitting here worried about the two astronauts making it home in that Boeing spaceship that never should've launched in the first place ❗ 😳
If you had told me, 10 years ago, that I would find a channel with fascinating and incredibly well researched stories of maritime disasters, I would have said, "Cool. I'll look forward to it...." And here I am.

I just feel for that kid. He didn’t want to go, but his father must have talked him into it, and it was on fathers day. Poor guy was just starting his life...
Seems to me that Cameron went about his deep dives in a steady, calculated manner and having seen the doco about his dive to the challenger deep I was impressed by his mad piloting skills 😎….and my gosh they didn’t even do the recommended hydrostatic tests 😮
Of course because Cameron knew the risks and they were high. If anything went catastrophically bad, he would been chummed into a meat cloud in .03 seconds. So he spent years designing looking at every flaw before manufacturing his machine.
@@andrewcardenas1314In a different universe, James Cameron would've been a deep sea diving expert by profession and a movie director by passion, basically the reverse of today. And honestly, I'd trust the expertise of James Cameron much more than that of the late Stockton Rush.
Besides being an interesting story, this is the best example of integrating a sponsor's product into the story without being obnoxious. Well done. A winning combination for all.
lol i hate when creators do that shit. wendover always inserts an ad into random sentences. i don’t expect every ad/sponsorship to go with the topic of the video so i hate when they try to force it like that. 😂
In regards to "running before you can walk," it's one thing when your problems result in crashed servers, data breaches, etc, it's entirely another if your problems are catastrophic hull failure at depth. Wow.
That mentality isn't even meant for preproduction parts/software, it's literally just for spitballing in the design phase to see what works and what doesn't. The fact that people apply "move fast and break things" to production is a complete misunderstanding of that saying.
Rush wanted to be a guy that broke all the rules he thought were holding him back from a revolutionary experience. And nature doesnt care how ambitious you are. Theres a reason safety comes first not innovation or ambition.
I honestly only feel sorry for the young guy. He didnt want to go. His father pushed him. His mother was supposed to go with the dad but they convinced the son to go as a fathers day present. He was terrified. The fathers stupidity killed the son
@@fffffffflei6589 this has been proven false many times. A family member made up the whole "he didn't want to go" lie. He actually did want to go, and was even excited to break a new rubik's cube record while on a submarine. Stop spreading lies to make the 19yr old seem like a martyr. It's crass.
@@catscanhavelittleasalami i dont see him as a martyr. He was an idiot just like the rest of them Nonetheless i feel sorry for him since he was only 19.
Here's the thing about the titanium tube that was on the inside of the carbon fiber, it was removed once the fiber wrap was completed only using titanium at both ends of the afts.
In theory Rush could have had a groundbreaking business and concept…if he did proper testing and development. He could have perfected the disposable submersible. If he could have proved and tested the unit to, let’s say 20-25 dives, reused the hemispheres and I’m sure he could have made money. If they got better then the process would become cheaper and the dives would have become more frequent. Too bad he did the cost cutting on the safety and testing part😑
You are talking about a man who consider safety to be pure waste. It would not been possible in practice for Rush to have perfected his submersible because it would never have been safe enough for multiple usage. Moreover, he insisted on using carbon fibre, and chose not to do proper testing even when his own safety officer warn him about it. His safety officer was fired by the way for asking him to do proper testing.
If the submersible has a lifespan of 25 dives then needs replacing it probably wouldn't be viable commercially. Actual DSVs have a service life that's usually measured in decades and thousands of dives. Yes that includes rebuilds but rebuilds cost a fraction of a complete new hull. For anyone who needs one for a few dives, hiring one and it's crew would make more sense than buying a 'disposable' model.
Ha ha ha ha ha, well this one was definitely disposable. Lets face it...at these depths and pressures, it is far easier to go above the atmosphere "Outer space", then it is to go in the opposite direction. Going towards the center of anything that is going to crush you, makes little sense when our Sun gives us Nuclear Fusion that gives us all the energy that we need for our survival. We don't need to go that far beneath the surface for what we need on the surface.
Nah, it was screwed overall when the guy decided to use CF. Based on his statement about its strength, it's clear that the difference in the strength of CF in compression being only a fraction of it's strength in tension, was totally ignored. When in compression CF only has 1/3rd to 1/2 of the strength that it has in tension. Using CF for this application never made sense, the reduced strength and issues with pressure cycling should have stopped the project when it was just a wild idea
Anyone who knows anything about composite materials would see a huge red flag when hearing "carbon fiber composite" and "submersible" in the same sentence
A side note: Stockton Rush's acoustic sensors were based on the idea of the Kaiser effect. The idea of the Kaiser effect is that as you put something under stress, as the struct compresses and pieces may rub together it will create a seismic or acoustic signal. If the load remains constant, the signal remains constant. This seems to have been observed in rock or concrete structures, as microcracks occur. The error in his practical use was, whether carbon fiber follows that, and also he never established what was the failure point. What I have seen for CF is a curve where load is compared to cycles, 20% load may allow a million cycles, while 80% may allow a hundred. This indicates that the failure of carbon fiber is progressive, the failures you're hearing aren't the old ones. He even had the observation that he heard more noise than the Kaiser effect predicted he would. Once the part has enough damaged spots, failure would increase until it got exponential. CF shatters, it absorbs enough force that it can't release it fast enough, like tempered glass. Voids would concentrate stress, and delaminations also would. Carbon fibers are a 1-d material, you can make a 2-d surface separated by epoxy, while metal crystals are 3-dimensional.
Thank you for sharing that. I've learned so much in the YT comment sections. Im always so impressed by the kind of knowledge and expertise people are walking around with.
I know you’re joking, but the controller in no way was a “weak point” if you could call it that. Game controllers are used in several ships and vessels to do the same purpose of that on the titan.
The writing is all over the place, same point is brought up multiple times like it were never mentioned earlier in the video. And that damn repeating background sound
I think it was more than milliseconds. There is evidence that they released their ballast and were trying to surface. There is evidence they knew there was something wrong, and were getting pings on those acoustic sensors he designed. He had time to realize just how wrong he was, and that it was going to kill him.
Been looking forward to your take on this. Can tell you've really taken the time to research and do this properly instead of doing it quickly and poorly to capitalise on the initial hype. Thank you!
I did not know that rush fired the engineer after the engineer wouldnt clear the submersible to be safe for what the intended use was. Thats insane and then sued him. I bet that engineer is glad that he was not the one that signed off on this.
Amazing breakdown and explanation.. Stockton is a murder. His intentional misinformation was used to get them to go when he knew all the issues. Him dying means nothing. The only sympathy goes to the other
He was still a human being. He deserves some sympathy, although he was a bit of a charlatan, quite greedy, and very reckless. He obviously really did believe in his contraption. He did have some success with it, which made him arrogant, but the vessel could only take but so much repeated use. I guess it cracked after a while. Ultimately imploded.
@@thetruthisthelight0910 I can’t agree with that I’m afraid. He used the very statistics which he said didn’t matter to “sell” the trip to unknowing customers. Those amazing safety statistics which he refused to follow are that good because of best practice and years of testing and research. He set his company up in a way that if any passengers died, it would keep his family from being sued as they were “specialists”. There is a major difference between passion and willful negligence. At every single turn he knowingly deceived everyone about almost every single aspect of his business.
@@MGJDMNJ Definition of slick and charlatan and reckless. He wasn't evil, he died as well. He was just stubborn and incredibly arrogant and grandiose. THAT'S sad.
@@thetruthisthelight0910 fair point. I guess it depends on what actions you view as evil. If just he and he alone died, it would be just another inventor who’s invention killed him. The evil part is having a willful disregard for anyone else’s life. Okay fast and loose with your own life if that’s what you want. I don’t care if believed he was right, that argument has been used through history to justify bad actions. Hitler believed his racial ideology fully and completely. It doesn’t excuse his actions. Btw I am not using this example as a reference to you and don’t want you to think so. I’m just using that example because it’s clear. Roughly 100 years ago, There was an inventory who was trying to to create a parachute. Famously his test was him wearing his own suit and jumping off the Eiffel Tower. He was also seeking to innovate and create with other materials (I think he as a curtain maker) and risked his life. Sad for sure. What rush did would be like telling people his parachute had been tested (which it hasn’t), was made of materials which were perfect (when in fact the opposite was true) and safe (without doing any safety tests). Furthermore, going out to actively sell this idea people and get them to try his parachute by parroting those features which were blatant lies and just hoping it went well. To me, that’s evil and takes a special kind of person to have absolutely no qualms about lying to others with no regard of their safety in an attempt to “innovate”. It shows a total lack of sympathy or empathy through active and knowing deception. His passengers families are now dealing with the consequences this mans actions. The number of people hit with tragedy could range in the hundreds when looking Spouses, children, siblings, in laws, employees etc.
@@MGJDMNJ Let's not descend into hyperbole. He was NOT akin to Hitler. That belief system was an ignorant, evil, ethnic & racial ideology that ignored the facts, and who GOD created, which is EVERYONE. Rush was a fascinating figure, --the books to come, will be interesting. He was such an apparent egomaniac & a narcissist, who was dumb enough, with all of his surface intelligence and college degrees, to take the proverbial "snake oil" that he was selling to others.
The story of ph nargolet is the main part of this story. He gave everyone else a false sense of security. His friends later reveal how excited he was to die like this and how he was ready to die after the death of his wife. Rush kept waiting on nargolet to push back, when he didnt rush felt safer than he was.
As usual you've brought new insights and made interesting a topic i've seen covered many times! One thing i feel the need to mention about carbon fiber is that it's like a rope in that it that it performs best under tension (pulling) vs. compression. For this reason it works great for air tanks, pressurized aircraft hulls and such where the fibers are being pulled but not in the case of Titan where the fibers are being pushed not pullsed so the only thing providing and strength really is the resin. I like how you pointed out that the need to be flexinble when innovating, make mistakes, learn from them, and change paths when necessary.
It's refreshing to hear someone talk about gas deepwater divers breathe, and not an ignorant reporter saying we breathe "Oxygen" down there. For those who don't know, you breathe mixed gases at pressure. Oxygen becomes a neurotoxin at about 25 feet or so. Oxygen in air gets toxic about 375', so you have to breathe a mix, such as Tri-ox.
An excellent and comprehensive account of the disaster. Rush was grotesquely negligent in his “rush to innovate”. People who believed what he was doing was safe lost their lives. They trusted him and gave him their money. That’s disgusting and he should not be praised for his approach, he should be remembered as someone who ended a teenagers life in his hunger to become famous and successful.
A simple way to understand why carbon fiber is not a good material for compressive loads is to imagine holding a piece in your hands. When you pull on it, in tension, it is incredibly strong, significantly stronger than steel. When you push on it, in compression, it immediately buckles with almost no resistance. In compression, it is the resin that provides much of the compressive strength. Also, this buckling of fibers results in delamination between the fiber and resin layers, which further weakens the bulk material over future compressive loads.
Carbon fiber is an excellent material for something like a car, both for high performance light weight exotics, and even things like trucks, as it's apparently holding up quite well in truck beds. But it has no place on other vehicles like a submarine. I'm stunned this proposal made it into the prototyping phase, let alone into active duty carrying passengers.
Hubris: the man suffered from extreme hubris. Even I know (retired industrial design model maker) that carbon fiber is made from carbon threads embedded in epoxy, and it inherits only tensile strength from the fibers. By crisscrossing built up fiber ribbons in different cross directions other strength characteristics can be gained or mimicked, giving other desired properties to make very strong light structures with tensile strength and added stiffness. But under no circumstances is carbon fiber resistant to compression loads. Stockton Rush didn't even do any sort of carbon fiber crisscrossing for the pressure hull. He merely wrapped carbon fiber ribbons around the inner cylinder. There was relatively low stiffness in his vessel, and vertually zero compression strength, save what the sandwiched epoxy resin afforded it. It had almost no high compression strength. Apparently Rush thought the high strength in carbon fiber tanks, under load from compressed gases and fluids, could be applied in reverse (highly compressed pressure from the outside in). It can't that's illogical; he would ultimately know that if he understood strength of materials (1st or 2nd year mechanical engineering courses). Without that basic knowledge I must say he either didn't research how carbon fiber really works, or he was simply a vert bad engineer. I've heard his engineering prowess was highly questionable; he lost several jobs because of it.
Just a brilliantly informative video. I'm a commercial diver and I think we talked briefly on your channel before. Even though I'm a diver I have no experience with manned submersibles. Of course I understand the physics of pressure you're talking about but your information about pressure hulls was fascinating. I learned a lot. Great job.
I've watched a few videos on this topic and I think this is the best one so far: concise explanations without any click bait type content or conspiracy theories. I love how clearly you explain things!
I would love to see the Titanic. I've been fascinated about everything Titanic since I was little. That said, never in my life would I ever go down in a submersible. It looks like a tiny water coffin.
I’m a fan of all your work, but I think this is your best video so far. The way you’ve explained the history & gone into detail to describe the complex technical aspects makes it really easy to understand.
I know people who were witness to the tests early on, the clip where Rush states it was “tested” to 300 meters(?) The model actually failed at that depth and they spun it. In addition my witness stated the wiring was awful and primitive as was the workmanship and design aspects.
Hey, Ive listened to the feedback. Ive deleted the duplicate sponsorship segments and kept the main one. Ive also put a timestamp in the description so its easy to navigate the sponsor chapter. Thanks for the feedback.
The video I've been waiting patiently, yeah right, for but quality isn't rushed nor cheap so here we are getting the Alvin version in a sea of net bouys.
AT LAST! A scientifically accurate and well presented description of the physics of pressure, depth and volume as it relates to diving. A brilliant, well organized presentation expertly done.
44:40, did he? What he constructed (or rather ordered), was not going to work. Engineers said so up front. So at best, what Rush "accomplished" was order an ill-equipped vessel with a mission for an unreachable destination over the backs of people he eventually got killed. He innovated nothing, he did excatly what every other business man does: throw money away on an idea that at best sounds interesting in theory, then goes on not wanting to pay for what is required to do it properly, cutting corners (and then some)
I really feel that the main two reason this happened was the cost-cutting surrounding non destructive testing and the fact that i truly believe that they descended too fast. They reached the titanic depth far too early and that plus the previous wear and tear from other dives is probably a large factor. Moving up too fast can be fatal and moving down too fast can be just as fatal.
If there vessel were able to withstand the force at depth then the rate of descent or ascent would not be a factor. On the descent the only thing that rate would possibly do is create momentum that they would need to slow before contacting the seabed.
It was never rated or tested for anywhere near the depth of the actual dives………so the point is kinda irrelevant. Also, the change in external ATM absolutely plays a factor when you consider the type of material used 🤷🏻♂️

The idea of replacing 55 year old wisdom-based cautiousness with 25 year old ambition in an industry where the health and well being of the customer is paramount is not exclusive to the deep sea submersible industry. Many an industry is being plagued with this new cavalier attitude in thinking “let us focus on what they got right.” At what cost? How many lives are you willing to sacrifice for the sake of hindsight?
Before the implosion, the Titan shot down like an arrow into the dark abyss for a little over a minute. Shooting all on board to the front of the Titan squeezing everyone together in darkness. I can't imagine the horror they felt before the big pop.

Stockton Rush didn't have some "disruptive" new technology, like he pretended. He was just willing to use a suboptimal hull shape, eat into safety margins with standard parts, use inexperienced designers (e.g. College students), and gamble his life/the lives of his passengers on using carbon fiber as the hull material, all in order to save on costs/maximize profits. If anything, this incident just shows why properly designed, tested, and certified deep sea submersibles are so expensive.
Additionally, it shows why capitalism has ultimately failed the human race. The reason for all of Rushs mind bogglingly stupid and evil choices were driven /solely/ by capital motives.
well, it's not really that the idea couldn't be of use. it's just that it might end up being really expensive to use properly(rebuild amounts) and nobodys properly tested the idea really (beyond that it does work a couple of times, which actually could be enough for some use cases, but now we wont know for a long while).
you need to test everything else regardless of what you're building it out of anyway and if you'd use it for commercial you would need to devise a way to test(xray etc) or have a replacement program for the parts based on the testing same as for airplanes - and you'd need the money to do the destructive testing to be able to record the signs what the checking program would look for.
doing it out of steel gets really expensive as well and would need the same program (it can also be inaccessible due to that sourcing the right alloys can end up way more complicated than one would think at fist.. politics getting involved kind of complicated).
I heard he was a member of bohemian grove
The fired engineer said he was a member of bohemian Grove. Being a money hungry death cult member I'm not at all surprised he had a death wish for himself and any high paying passengers.
Expensive and absolutely necessary
When I was a kid a friend and I drew up a set of plans to turn a old propane tank into a submersible, and we were going to charge other kids to ride to the bottom of a old strip mine water pit. We lost the plans and never built it. Now I know who stole the plans.

As long as Rush was only endangering himself, power to him, he can do whatever he wants. But the fact that he was allowed to kill four other people through his willful negligence is an absolute crime.
He even tried to talk a younger woman working for him to take over as pilot of the thing.

I am surprised at how many content creators continue to praise Rush and refer to the outcome as some unfortunate event as if there was no negligence.
This was entirely foreseeable, let's not forget that Ocean Gate knew the vessel would not pass regulation and testing, therefore they chose not to get the Titan certified for this very reason.
Furthermore, the most egregious act being the termination of engineer for trying to alert Rush and Ocean Gate that the vessel was not safe. Rather than addressing these concerns he fires him for speaking up.
This is no accident, this is the result of a truly negligent CEO who ignored and silenced sound engineering advice, deliberately avoided certification and 4 innocent people lost their lives.
Not to mention he was too cheap to get a ship that could actually transport it on board instead of dragging it through the ocean on a raft behind it. That’s a huge red flag to me in itself.

The controller choice while frugal, was unlikely to ever cause anyone to die! The poorly designed and insufficiently tested hull is (was!) the problem, forget the stupid controller as it really was not that big of a deal, it didnt cause the hull to implode and that's what killed the people.

Getting a supercar to reach 400km/h (250mph) is relatively easy. Getting to that speed SAFELY is a whole lot more difficult. Hence why the properly engineered supercars needed many years of research and testing using the best materials and the death trap kitcars and glorified tuners do it the way Stockton Rush did it - by cutting corners.

One thing about Stockton Rush is he honestly believed that those safety protocols were just BS, even though most all of those procedures are written in blood and are lessons learned from other accidents. He put his life on the line along with others and paid the ultimate price.

Dude basically tried to fight the ocean with predictable results
Indeed, i work in electricity and ppl always look at safety regs are there to piss you off. Ive seen people get hurt, maimed and killed by taking shortcuts.

Thanks. 👍🏻😀
One important thing to note, some experts agree that the sensors were a gimmick. There was no testing confirming that they would work or even provide enough time to do anything.
That sounds very on brand for Rush.
I explained it in more detail in my comment, but essentially the time between "sensors warning you" and "catastrophic failure" is in the seconds to milliseconds range. Enough to inform you of your imminent death, not enough for you to do anything about it.

A technical or engineering mistake i can understand but how do you get which ocean the most famous shipwreck in history wrong? Smh
I got a ad for Progressive Boat Insurance while watching this...
🤣
One quibble I have is that the US Navy's SOSUS network is actually **extremely** good at localizing the origin points of sufficiently loud sounds such as implosions. This was ably demonstrated with a number of lost submarines during the Cold War.
Indeed. It was and is highly useful at not just detecting the sounds but finding where they came from. Without SOSUS, it would have taken far longer than a couple of months to find where Thresher and Scorpion went, as well as other incidents.
I came here to say the same thing. They knew within minutes of the implosion. I do believe the navys explanation of why they waited is just a cover to hide the full capabilities of the system.
i think it's obvious that they knew where it imploded. as soon as they got the equipment, they went straight there. the "search" before that was nonsensical, though, and not disclosing the information about hearing the implosion.
The problem with carbon fiber lies with the fact that it's main strength lies in tension, not compression.
However it's used extensively in racing car crash structures.
@@nikoscosmos I think it's used in cars for weight loss, not to provide survival-ability when the car hits a brick wall. You can have carbon fiber spoiler and car body, but the cage that protects the driver is still made of alloy of sorts.
@@nikoscosmos the pressure there is a sharp tension pressure, that is, longitudinal to the fibers...
cars or airplanes rarely require withstanding pressure vectors perpendicular to the fiber structure (where your only carrying strength is the binding epoxy), the exception is carbon fiber wings, but even there, they can use elasticity transferring the fiber strength that way to compensate for it (why you get so much movement in a 787 wing)... you cannot do it with pressure.
@@nikoscosmos nope the race course provides that.
@@nikoscosmosThe carbon fiber in cars isn't to prevent the cars from crumpling. Besides, crumpling is what you want in a crash. Crumpling, rolling, and shedding displaces the energy away from the driver (and passenger, where applicable). That's why NASCAR wrecks are so fantastical most of the time, and drivers still walk away with little to no injuries. When NASCAR drivers DO get hurt, it's in wrecks that usually don't look flashy. The wreck that killed Dale Earnhardt was super simple. No rolling, no major crumpling, little if any shedding... Just a smack into the wall, and he was finished. If carbon fiber prevented crumpling, race cars wouldn't use it because it would make the cars more dangerous.
Sir, this is one of your finest, together with the Kursk and Thresher stories. I love it
Awesome. Thanks for watching👌🏻
32:17 See, I don't agree with that. If you look at the stress-strain curve for carbon fiber, there's no warning whatsoever before failure. The yield point is the failure point. I know they heard noises when the hull was new but that is probably just weaker fibers breaking. Even the Engineer who was allegedly fired for refusing to rubber stamp the design said the same thing about the amount of warning you'd get.

I came here to say the exact same thing. This channel is pure gold.
Exactly, most others focus on a "gist" or "feeling" about events. This is not that. That acrylic window was tested to 1,300 meters. And then Rush just took it to 4,000 meters over and over crossing his fingers. Same with non destructive testing of the pressure vessel, it's expensive but subjecting a carbon-fiber pressure vessel to repeated cycles of compression and decompression before analyzing the microscopic changes...Simply has to be done before sinking it to the bottom of the sea many times, with many lives on board.
Excellent video.
Thanks I appreciate that
I think of the simplest examples is putting that limiting factor, deep sea challenger, and titan next to each other. You can see what serious professionals do, and what an amateur out of his depth has done. It's a stark difference. I wouldn't be so upset of this guy trying something new and innovative. But doing it at the cost of others lives is just beyond reckless.
It help to have endless charisma
There is nothing 'innovative' about recklessness. Sidestepping accepted protocols to get to the cookie jar first isn't new, and it always ends badly. It's what jackasses do, and jackasses will always be with us. The trick is to recognize them for what they are before they can cause irreparable damage. And 'innovation', whatever that golden calf is, is not a substitute for sound engineering analysis regardless of what nontechnical folks would prefer to believe. In a different age Stockton Rush would be selling patent medicines off the back of a horse drawn cart.

In regards to "running before you can walk," it's one thing when your problems result in crashed servers, data breaches, etc, it's entirely another if your problems are catastrophic hull failure at depth. Wow.

Thanks, I really appreciate that
In theory Rush could have had a groundbreaking business and concept…if he did proper testing and development. He could have perfected the disposable submersible. If he could have proved and tested the unit to, let’s say 20-25 dives, reused the hemispheres and I’m sure he could have made money. If they got better then the process would become cheaper and the dives would have become more frequent. Too bad he did the cost cutting on the safety and testing part😑
Its the design of the Titan too, it was flimsy and shoddy.
You are talking about a man who consider safety to be pure waste. It would not been possible in practice for Rush to have perfected his submersible because it would never have been safe enough for multiple usage. Moreover, he insisted on using carbon fibre, and chose not to do proper testing even when his own safety officer warn him about it. His safety officer was fired by the way for asking him to do proper testing.
If the submersible has a lifespan of 25 dives then needs replacing it probably wouldn't be viable commercially. Actual DSVs have a service life that's usually measured in decades and thousands of dives. Yes that includes rebuilds but rebuilds cost a fraction of a complete new hull. For anyone who needs one for a few dives, hiring one and it's crew would make more sense than buying a 'disposable' model.
Ha ha ha ha ha, well this one was definitely disposable. Lets face it...at these depths and pressures, it is far easier to go above the atmosphere "Outer space", then it is to go in the opposite direction. Going towards the center of anything that is going to crush you, makes little sense when our Sun gives us Nuclear Fusion that gives us all the energy that we need for our survival. We don't need to go that far beneath the surface for what we need on the surface.
Nah, it was screwed overall when the guy decided to use CF. Based on his statement about its strength, it's clear that the difference in the strength of CF in compression being only a fraction of it's strength in tension, was totally ignored. When in compression CF only has 1/3rd to 1/2 of the strength that it has in tension.
Using CF for this application never made sense, the reduced strength and issues with pressure cycling should have stopped the project when it was just a wild idea
Anyone who knows anything about composite materials would see a huge red flag when hearing "carbon fiber composite" and "submersible" in the same sentence
That's what everyone has been saying since the implosion, yes.

A side note: Stockton Rush's acoustic sensors were based on the idea of the Kaiser effect. The idea of the Kaiser effect is that as you put something under stress, as the struct compresses and pieces may rub together it will create a seismic or acoustic signal. If the load remains constant, the signal remains constant. This seems to have been observed in rock or concrete structures, as microcracks occur.
The error in his practical use was, whether carbon fiber follows that, and also he never established what was the failure point. What I have seen for CF is a curve where load is compared to cycles, 20% load may allow a million cycles, while 80% may allow a hundred. This indicates that the failure of carbon fiber is progressive, the failures you're hearing aren't the old ones. He even had the observation that he heard more noise than the Kaiser effect predicted he would.
Once the part has enough damaged spots, failure would increase until it got exponential. CF shatters, it absorbs enough force that it can't release it fast enough, like tempered glass. Voids would concentrate stress, and delaminations also would. Carbon fibers are a 1-d material, you can make a 2-d surface separated by epoxy, while metal crystals are 3-dimensional.
that was a really interesting read thanks :)
It’s almost as if there’s a reason that professionals don’t build deep sea submersibles out of carbon fiber for a reason? 🤷🏻♂️
Yeah, I heard that in a nutshell: when the system detects sounds above certain treshold it means the failure is imminent, leaving no time to surface.

Thank you for sharing that. I've learned so much in the YT comment sections. Im always so impressed by the kind of knowledge and expertise people are walking around with.
"Hey whats this made of?"
Stockton: "Chill (beginning descent.)"
*crack sounds in background*
_"The carbon fiber playstation submarine."_
lol. Imagine thinking any of that was a good idea.
hey, it's just casue we aren't engineers. we're too stupid to see the brilliance
I know you’re joking, but the controller in no way was a “weak point” if you could call it that. Game controllers are used in several ships and vessels to do the same purpose of that on the titan.
@@rikupv they’re used for periscopes and small operations not for controlling every system and monitoring.
What amazes me is it actually went down and up successfully a few times
My science teacher said the day would come when I would regret skipping class for 2 years to do bong hits in the parking lot. And here we are...
🤣I was told the same
@@waterlinestories well one of us proved them right
The writing is all over the place, same point is brought up multiple times like it were never mentioned earlier in the video. And that damn repeating background sound
Imagine the look on Stockton's face in that milliseconds it took to realise that he was wrong all along.
I think it was more than milliseconds. There is evidence that they released their ballast and were trying to surface. There is evidence they knew there was something wrong, and were getting pings on those acoustic sensors he designed. He had time to realize just how wrong he was, and that it was going to kill him.
😂
And the 4 passengers?
@@Lawyerboyleslie72Idk I wasn't there bro
doubt he had time to make a face
Been looking forward to your take on this. Can tell you've really taken the time to research and do this properly instead of doing it quickly and poorly to capitalise on the initial hype. Thank you!
You put more research into this video than Rush did into his submersible
🤣
I did not know that rush fired the engineer after the engineer wouldnt clear the submersible to be safe for what the intended use was. Thats insane and then sued him. I bet that engineer is glad that he was not the one that signed off on this.
Amazing breakdown and explanation.. Stockton is a murder. His intentional misinformation was used to get them to go when he knew all the issues. Him dying means nothing. The only sympathy goes to the other
He was still a human being. He deserves some sympathy, although he was a bit of a charlatan, quite greedy, and very reckless. He obviously really did believe in his contraption. He did have some success with it, which made him arrogant, but the vessel could only take but so much repeated use. I guess it cracked after a while. Ultimately imploded.
@@thetruthisthelight0910 I can’t agree with that I’m afraid. He used the very statistics which he said didn’t matter to “sell” the trip to unknowing customers. Those amazing safety statistics which he refused to follow are that good because of best practice and years of testing and research. He set his company up in a way that if any passengers died, it would keep his family from being sued as they were “specialists”.
There is a major difference between passion and willful negligence. At every single turn he knowingly deceived everyone about almost every single aspect of his business.
@@MGJDMNJ Definition of slick and charlatan and reckless. He wasn't evil, he died as well. He was just stubborn and incredibly arrogant and grandiose. THAT'S sad.
@@thetruthisthelight0910 fair point. I guess it depends on what actions you view as evil. If just he and he alone died, it would be just another inventor who’s invention killed him.
The evil part is having a willful disregard for anyone else’s life. Okay fast and loose with your own life if that’s what you want. I don’t care if believed he was right, that argument has been used through history to justify bad actions.
Hitler believed his racial ideology fully and completely. It doesn’t excuse his actions. Btw I am not using this example as a reference to you and don’t want you to think so. I’m just using that example because it’s clear.
Roughly 100 years ago, There was an inventory who was trying to to create a parachute. Famously his test was him wearing his own suit and jumping off the Eiffel Tower. He was also seeking to innovate and create with other materials (I think he as a curtain maker) and risked his life. Sad for sure.
What rush did would be like telling people his parachute had been tested (which it hasn’t), was made of materials which were perfect (when in fact the opposite was true) and safe (without doing any safety tests). Furthermore, going out to actively sell this idea people and get them to try his parachute by parroting those features which were blatant lies and just hoping it went well.
To me, that’s evil and takes a special kind of person to have absolutely no qualms about lying to others with no regard of their safety in an attempt to “innovate”. It shows a total lack of sympathy or empathy through active and knowing deception. His passengers families are now dealing with the consequences this mans actions. The number of people hit with tragedy could range in the hundreds when looking Spouses, children, siblings, in laws, employees etc.
@@MGJDMNJ Let's not descend into hyperbole. He was NOT akin to Hitler. That belief system was an ignorant, evil, ethnic & racial ideology that ignored the facts, and who GOD created, which is EVERYONE. Rush was a fascinating figure, --the books to come, will be interesting. He was such an apparent egomaniac & a narcissist, who was dumb enough, with all of his surface intelligence and college degrees, to take the proverbial "snake oil" that he was selling to others.
The story of ph nargolet is the main part of this story. He gave everyone else a false sense of security. His friends later reveal how excited he was to die like this and how he was ready to die after the death of his wife. Rush kept waiting on nargolet to push back, when he didnt rush felt safer than he was.
Only 3 minutes in and I can already tell the research is way better than any other video I have seen on the same subject. Thank you.
This is just pro rush bullshit.
Really ? so the Titanic is in the Pacific huh !
When I meditate to clear my mind I think of Stockton's toupee wafting along the seafloor with the current.
Hahahaha brilliant 😂 What a way to find your zen
They disintegrated homie
Do you envision the 4 passengers imploding?
I hate that I'm laughing too hard at this.
I didn’t no he wore a tupee ? But imagine it would have just disintegrated with him
Very informative and educational. I learned much about air and water pressure.
Good stuff👍🏻
As usual you've brought new insights and made interesting a topic i've seen covered many times! One thing i feel the need to mention about carbon fiber is that it's like a rope in that it that it performs best under tension (pulling) vs. compression. For this reason it works great for air tanks, pressurized aircraft hulls and such where the fibers are being pulled but not in the case of Titan where the fibers are being pushed not pullsed so the only thing providing and strength really is the resin. I like how you pointed out that the need to be flexinble when innovating, make mistakes, learn from them, and change paths when necessary.
19:50 "needlessly prioritizes passenger safety over commercial innovation" NEEDLESSLY HOW
It's refreshing to hear someone talk about gas deepwater divers breathe, and not an ignorant reporter saying we breathe "Oxygen" down there.
For those who don't know, you breathe mixed gases at pressure. Oxygen becomes a neurotoxin at about 25 feet or so. Oxygen in air gets toxic about 375', so you have to breathe a mix, such as Tri-ox.
👍🏻
An excellent and comprehensive account of the disaster. Rush was grotesquely negligent in his “rush to innovate”. People who believed what he was doing was safe lost their lives. They trusted him and gave him their money. That’s disgusting and he should not be praised for his approach, he should be remembered as someone who ended a teenagers life in his hunger to become famous and successful.
A simple way to understand why carbon fiber is not a good material for compressive loads is to imagine holding a piece in your hands.
When you pull on it, in tension, it is incredibly strong, significantly stronger than steel.
When you push on it, in compression, it immediately buckles with almost no resistance.
In compression, it is the resin that provides much of the compressive strength.
Also, this buckling of fibers results in delamination between the fiber and resin layers, which further weakens the bulk material over future compressive loads.
Carbon fiber is an excellent material for something like a car, both for high performance light weight exotics, and even things like trucks, as it's apparently holding up quite well in truck beds.
But it has no place on other vehicles like a submarine. I'm stunned this proposal made it into the prototyping phase, let alone into active duty carrying passengers.
Hubris: the man suffered from extreme hubris. Even I know (retired industrial design model maker) that carbon fiber is made from carbon threads embedded in epoxy, and it inherits only tensile strength from the fibers. By crisscrossing built up fiber ribbons in different cross directions other strength characteristics can be gained or mimicked, giving other desired properties to make very strong light structures with tensile strength and added stiffness. But under no circumstances is carbon fiber resistant to compression loads.
Stockton Rush didn't even do any sort of carbon fiber crisscrossing for the pressure hull. He merely wrapped carbon fiber ribbons around the inner cylinder. There was relatively low stiffness in his vessel, and vertually zero compression strength, save what the sandwiched epoxy resin afforded it.
It had almost no high compression strength. Apparently Rush thought the high strength in carbon fiber tanks, under load from compressed gases and fluids, could be applied in reverse (highly compressed pressure from the outside in). It can't that's illogical; he would ultimately know that if he understood strength of materials (1st or 2nd year mechanical engineering courses). Without that basic knowledge I must say he either didn't research how carbon fiber really works, or he was simply a vert bad engineer. I've heard his engineering prowess was highly questionable; he lost several jobs because of it.
Just a brilliantly informative video. I'm a commercial diver and I think we talked briefly on your channel before. Even though I'm a diver I have no experience with manned submersibles. Of course I understand the physics of pressure you're talking about but your information about pressure hulls was fascinating. I learned a lot. Great job.
I've watched a few videos on this topic and I think this is the best one so far: concise explanations without any click bait type content or conspiracy theories. I love how clearly you explain things!
The guy in the beginning who decided to put himself in a box then sink it. Like wtf lol What a way to start the show! 😂😂😂
I would love to see the Titanic. I've been fascinated about everything Titanic since I was little. That said, never in my life would I ever go down in a submersible. It looks like a tiny water coffin.
I’m a fan of all your work, but I think this is your best video so far. The way you’ve explained the history & gone into detail to describe the complex technical aspects makes it really easy to understand.

Did they know that?
@@Lawyerboyleslie72 did the designer of the vessel know how it was made?
😆
ok
I know people who were witness to the tests early on, the clip where Rush states it was “tested” to 300 meters(?) The model actually failed at that depth and they spun it.
In addition my witness stated the wiring was awful and primitive as was the workmanship and design aspects.
wiring was primitive or simple? if wiring is like a web, you can't really fix it in short time
@@vipvip-tf9rw By primitive I mean it didn't have stuff like circuit breakers etc.
In the end he definitely left his mark on the engineering / ocean exploration industry
This video needs an award for most plugs for Brilliant in a single video 😅
This didn't go down how I thought it would😂
Hey, Ive listened to the feedback. Ive deleted the duplicate sponsorship segments and kept the main one. Ive also put a timestamp in the description so its easy to navigate the sponsor chapter. Thanks for the feedback.
Rush sadly lived up to his namesake.
0:36 Oceangate was rushing to built a submarine because the CEO name was Stockton Rush. The answer was always there.
The video I've been waiting patiently, yeah right, for but quality isn't rushed nor cheap so here we are getting the Alvin version in a sea of net bouys.
AT LAST! A scientifically accurate and well presented description of the physics of pressure, depth and volume as it relates to diving. A brilliant, well organized presentation expertly done.
Thanks
44:40, did he? What he constructed (or rather ordered), was not going to work. Engineers said so up front. So at best, what Rush "accomplished" was order an ill-equipped vessel with a mission for an unreachable destination over the backs of people he eventually got killed.
He innovated nothing, he did excatly what every other business man does: throw money away on an idea that at best sounds interesting in theory, then goes on not wanting to pay for what is required to do it properly, cutting corners (and then some)
I really feel that the main two reason this happened was the cost-cutting surrounding non destructive testing and the fact that i truly believe that they descended too fast. They reached the titanic depth far too early and that plus the previous wear and tear from other dives is probably a large factor. Moving up too fast can be fatal and moving down too fast can be just as fatal.
If there vessel were able to withstand the force at depth then the rate of descent or ascent would not be a factor.
On the descent the only thing that rate would possibly do is create momentum that they would need to slow before contacting the seabed.
It was never rated or tested for anywhere near the depth of the actual dives………so the point is kinda irrelevant. Also, the change in external ATM absolutely plays a factor when you consider the type of material used 🤷🏻♂️
I like it better when the sponsored stuff is in one part of the video cuz otherwise it feels like I'm being constantly nagged.

The idea of replacing 55 year old wisdom-based cautiousness with 25 year old ambition in an industry where the health and well being of the customer is paramount is not exclusive to the deep sea submersible industry. Many an industry is being plagued with this new cavalier attitude in thinking “let us focus on what they got right.” At what cost? How many lives are you willing to sacrifice for the sake of hindsight?
I've watched a ton of videos on the topic. This was by far the most interesting and well researched I've seen. Nice work!
Thanks, I really appreciate that
I really like the format of this episode - jumping back and forth between the mission and the backstory makes it a compelling narrative:)
Fist rule of exploration: respect Nature, because she has f$#@all respect for you.
Hold on a second... Those end caps were only GLUED on? Are you kidding me?!!
That's exactly what I thought, And it almost certainly played a role in its destruction.
The overlap with the hull was also not deemed sufficient for the different compression rates of the metal / cf
Before the implosion, the Titan shot down like an arrow into the dark abyss for a little over a minute. Shooting all on board to the front of the Titan squeezing everyone together in darkness. I can't imagine the horror they felt before the big pop.
True the only good thing i found bout kt is prob stocktons face and realization he got when he knew he is fked
Thats good though, no mercy for the rich
No it didn’t

Ah yes, the classic trope… I went to school for business administration, I am now more qualified than engineers.
I think it's cool you coverd this and im glad you took the time to what until the story was out and the information was correct instead if jumping on the band wagon like most channels. You are patient enough to give a topic time but also you still cover it with I appreciate. Some channels would wait years before covering something like this because of fearing the politics involved. Keep it up.
Side note like the new logo but almost scrolled past cuz I didn't recognize it as yours. Glad I saw it tho love the long video like the one where the group of kids where stuff in a cave as it flooded, very entertaining stuff
I SCUBA dived one time and I am in no rush to do it again. While it was a cool experience, knowing the dangers if anything goes wrong is too much for me to try it again.
That limiting factor spherical hull was pressure tested in st Petersburg russia , that was the only facitly that could produce the pressures of how deep they were going .
Your videos are one of my favourites one TH-cam.. so well informed and well told..
It’s easy to tell you have had real world experience in a lot of what you talk about and that goes a long way..
Thanks I really appreciate you saying that👍🏻
