- Jeff Ostroff walks you through the details, specs, and red flags of the Titan sub-disaster, offering a few possible root causes for the implosion and catastrophic loss that claimed 5 lives. The OceanGate Titan Submarine submersible vessel imploded on Sunday, June 18, 2023, at about 9:45 AM, and the debris was found 1600 feet from the bow of the Titanic shipwreck on the Atlantic Ocean Floor. This Titanic sub documentary will focus on a handful of theories for the cause of this Titan submarine implosion, piloted by OceanGate CEO Stockton Rush, among the 5 total victims.

Jeff - You did an excellent job with this.
The interesting thing about Titan's hull integrity monitor, it was wound in to the carbon fiber itself during construction. So if it did pickup any anomalies, the warning probably happened AFTER the implosion occurred. My feeling is this entire sub was crap and they used marketing tactics like you showed to mitigate the low quality. Hearing the CEO make comments about not wanting to hire "50 year old white guys" shows also he didn't want to be challenged. This was entirely avoidable, he was a fool for taking out passengers. Gamble with your own life, not with others. - Thanks again for the great video

Come this way...
Thanks so much for helping us to understand this terrible event. So sorry for the families.
@@fjs1111 Well-spoken, thanks!
@@audioauracle-dsyswpwanl- I would love to see him do a movie on this with George Clooney
I'm a retired engineer, electrical not mechanical. You are absolutely correct about technical limits on materials such as this sub design. It's insane this guy took the sub to it's breaking point. It's sad but a good lesson to future explorers. Don't push the physical limitations of the materials and design.
He basically designed it to fail
Yes, you don’t estimate something to handle a certain dept then take it past that point. Like having a service pulling 180 amps and using a 150 amp main.
Stupidity was the problem in this case" people with money" pushing people away who tell them its Dangerous!😳 8:36
Especially if this material they used to manufacture sub hasn't been tested for safety and durability.
But these lessons were already learned, he just chose to ignore them.
FYI, the Navy did NOT keep the fact that they heard sounds consistent with an implosion secret. They didn't announce it to the public, but they DID inform the coast guard and the rescue command center. It was decided they would keep searching anyway, because JUST the sound was not "conclusive"
@@altern8tivegonna leave us all in suspense orrrrr?
@@dollarbutt
Hey, stop being antisemitic
@@dannylamb456 uh...weird troll attempt?
Just because the Navy heard a sound that was consistent with an implosion is NOT confirmation enough that in fact the Titan had imploded and that they can stop searching for it. Hearing sounds is not concrete evidence. They also heard banging noises too and those turned out to be nothing. You stop searching when you find physical and concrete evidence.
@@altern8tivecareful, they’re always watching/listening…. But several headlines were sidelined due to this event. You’re absolutely correct
Their claim of a 4,000 meter max depth and the fact that they planned on taking it near 3,800 meters is absolutely insane
Like, "Hey, let's push the sub to 95% of its max depth. What could go wrong?"
And after it had already done so many trips!
I heard they could have used ultrasound to check for defects but didn't.
I saw the PR video with Stockton Rush. I diagnosed him as a sociopath/narcissist in 5 minutes. Also many if his "followers" use words like "I adored him" "He was the right man for the mission" "I would trust him with my life" and so on. Everybody is talking about Rush and his charisma! Nobody is talking about the vessel!
That's a sure sign they have been gaslighted by a sociopath!
Which one? I wanna diagnose too.
Tells you a lot about the company and the person who ran it when you hear that an employee who gave them some bad news concerning the design of the sub was right away asked to clear out his desk and leave. May all who lost their lives in this incident Rest in Peace.
How have we become a culture that can't voice differing opinions without fear of retribution? I swear this is a running theme this year through politics and other things-not just about carbon fiber.
I agree, that was a big huge flag.
Ignoring warnings killed titanic and the titan submersiville
I'll bet the documentation of the former employee's wrongful termination lawsuit is exhibit #1 in the coming wrongful death lawsuit(s) against the company.
Except Mr Rush.
My husband served in our US Navy on trident submarines. He shared with me that Stockton once made the comment that he didn’t want a “bunch of 50 year old submarine vets” on his team. I guarantee if he would have, this would not have happened. That submersible had many red flags and any veteran submariner could have pointed that out to him. In the end, his ego killed him and the other tourists.
Stockton did not want the experienced "old white " guys calling him out! What an idiot! If he wanted to kill himself (it does seem like a suicide mission) , he should have went alone!
I think the CEO said that he didn't want a bunch of 50 year old "white guys" on his team. I think he said that 50 year old white guys aren't inspiring.
Those 50 year old vets probably cost too much money. Bring in the 30 year old "cheap" labor.
@@warrenlewis3977'm just guessing but I would say it was more that he only wanted yes men and people with less experience than him so he could not only overrule them as CEO but also on a know how level.
@@irieite9666 I agree with you. The trades are full of people like the former CEO. I paint boats and cars for a living,, do some welding too. There's always that one guy that thinks he knows everything. The CEO didn't want to pay for expertise along with arrogance and greed. These character flaws cost him is life.
Very good commentary. As a retired engineer myself, I am appalled at the many points of potential failure. I was an electronic, mechanical and quality engineer. I feel my work as a quality engineer to be the most important job because I had to closely monitor and correct all facets of design and supply as I discovered them. Your analysis is spot on and I appreciate you taking the time to illuminate the need for superior design and manufacturing.
Kap
Nice one, Jeff.
On one mission. Stockton's team of innovative, spotty young 'engineers' had mounted a propulsion unit back-to-front and the pilot found himself performing donuts on the ocean floor. After fiddling with the software that connected the game controller to the motors the pilot was able to hold it the wrong way round and gain some sort of control over the vehicle.
To release some of the ballast (old pipes) the crew were required to all shift to one side of the vessel. Presumably, they then had to all pile to the other side to dump the rest. What a shambles.
What beats me is why intelligent, successful and VERY rich people were drawn into riding this deathtrap contraption.
I'm guessing that Stockton Rush could have sold snow to the Inuit.
Beeing rich doesnt mean you got all your wires connected
Its easy to say now that it imploded and all this has come out about experts saying it was unsafe. But as someone who isn't an engineer and the fact that none of the safety concerns were really public, if I was given a free ticket I would have considered it
@@Hadzz95 well said..until the incident i doubt anyone publicly knew of all the issues..these details only come out after a major incident
@@Hadzz95 Never forget the adage: "If it seems too good to be true at first glance, it probably is". To ensure your safety -survival in some cases, you must question the process/procedure and ask questions, make inquiries. Never take anything for granted or at face value. It all comes down to 'buyer beware'.
@@lynnemenard5910 I get what you're saying, but too good to be true would be like a used car for $500 with "no issues". A ticket cost quarter a million and industry experts were riding on it. I'm more saying if I was given a free press ride or something, I would consider it but not necessarily go. Especially after reading that waiver
This is so very sad. The person who was let go because of saying it was unsafe in my opinion is an amazing example of truthfulness. I would hire him in an instant knowing I could trust him on his analysis without even questioning him. I do hope the best for him and at the same time pray for the families of these victims.
just glad you dont say RIP to the deceased people as so many say, as one cannot pray fore the dead souls, thy cant hear us once dead.
Give that guy a book deal!
even james cameron warned them, a real true sub expert! holds the deepest dive in a submersible/ and submarine, and he took it as an insult, not a friendly safety warning, he told them not to take people in the Titan it was not safe, i mean the porthole was only rated for 1,300 meters, not even close to the 4000 meter requirement, common, anyone would say that's not safe!, it was that 250k a passenger, his greed made him stupid!
From the way Stockton Rush carried himself and spoke, one can clearly see a lack of humility and concerns: it's strictly business and "innovation"
Yes, but imagine the footnote he can put on his resume from now on.
I wonder how that fired engineer must feel now. A strange mix of grief and despair and yet an immense feeling of validation.
I guess they kept adding carbon fibre till it was five inches thick, and assumed that would be enough, but I thought carbon fibre was best at tension
You've been the most reliable and knowledgeable regarding this tragedy.
I also love your voice
Thanks, I'm glad you liked it!
I hope you continue to make videos analyzing disasters and accidents. You're very good at explaining it and I'd definitely watch them all. 👍
Thanks Emily! Yes I have many more to come, continuing the Champlain Towers collapse, and then going back to cover old famous disasters
Primary root cause: Hubris.
Ironically and tragically in the Titanic's wake. Hubris brought it down too.
Secondary cause: no life jackets
This guy Hubris has caused so many problems over the years
Gosh hubris sounds like a horrible guy 😂
@@nos4menot enough life boats either.
This guy took the sub to it's breaking point over and over until stress fatigue came into play!
These guys are simply idiots. That's what having too much money does. 😂
And then they got popped by a megolithic reverse kuhweef!
After all the cycles that Sub had it should have been scrapped and start over
Exactly. His rule breaking was just the dumbest move ever. People don’t like it but it’s a fact. Everything has a service life! Unless something is used in such light service, meaning it is never pushed into cycling the material, ie. flexed, bent, stretched and so on to it’s “yield point” or the point where there is permanent deformation, it will only function so many times before fatigue, leads to failure. Failure being the operative term here. Failure that led to the gross negligence that killed 5 people, 4 who trusted one that used a waiver instead of due process! Stupidity! Nobody else wants to say it so I did. He was stupid and shouldn’t have been the only one in control. 30 letters by qualified concerned experts should have shut this irresponsible amateur down. I have ideas too but I’ll never risk my life or anyone else’s trying them.
Its only conclusion to me is that it was an actual suicide mission and as it was so obvious the sub was going to implode then it was a pre planned murder of people this guy wanted to end the lives of, what other reason could there be?? Theres more to this than is known..theres a psycopathic maniac possesed by a goal to murder and a suicide pact..
I'm not an engineer, but I am married to one and have many in my family including one who is a quality engineer, and I previously worked in automotive, so I'm familiar with safety standards and have heard similar conversations over the years from family members. From my little, unrelated knowledge, I'm horrified by how many risks the company seems to have taken, in the face of every other person in their field yelling and screaming that there would be an issue just like this, only for it to come to pass.
I appreciate your efforts in researching the patent documents, lawsuits, prior issues, etc to create this video. I know it's alot of work, where most content creators will just push out a video full of their opinions with no receipts just to be one of the first videos out there for views.
I respect your research and methodical approach to presenting the information. Always great videos with solid info Jeff. Keep up the great work. Many of us out here recognize those like you who are knowledgeable in their videos as opposed to those who are just uniformed op-ed commentators.
The biggest differences for James Cameron and his Deep Sea Challenger are a.) every precaution they could take was done even though it too was experimental, b.) James Cameron was part of the design from day one and was well aware of the potential risks of death, c.) the sub was only meant to go to that depth once and then retired. He also never took passengers down. He was taking the risk himself.
Cameron seemed to be very well educated on all those safety procedures
James Cameron has proven he respects the many layers it takes to reach Titanic. He respected the experts, he respected the research, he respected the history, and he respected those who died on the voyage. To me, Rush didn’t respect any of this and saw Titanic as a notch to mark. Cameron never even tried to profit off of his dives, it was purely researching and reconnecting with history, meanwhile Rush was attempting to turn his company as a tourist hotspot for the ones who can pay $250 k for a seat.
The two had difference approach to the expedition, Cameron learned the lessons of Titanic’s sinking, Rush didn’t and it resulted him repeating history.
@@kate2create738interesting, thank you for your insight!
Plus, Cameron used a proven design and proven materials.
That's something that had not occurred to me.
A submersible would need regular repair and inspection before and after every trip. Even 1 trip can weaken the exterior and it gets weaker every time it dives.
I’m a former nuclear submarine sailor. I’d have never got on that death trap
Lawrence, I don't think they did!
Unfortunately it was a death trap. So sad that those aboard didn't see that. There were so many warnings. 😢
The submarine ride at Disneyland is as close as I will ever get to the real thing.
@@RobertBreckenridge13hahahaha me too!
I’m currently designing a submarine with sails, what do you think?
It made me think back to the Space Shuttle Columbia disaster where they started to get sensor alarms as the wing began to fail for a few minutes before the final catastrophic failure. For Titan, I guess there was a leak into the rear compartment, from the start, so it sank faster than planned, and water started to get into the electrical system. The mother ship crew were probably under instructions not to say anything that would worry the paying passengers, and leave it all to Stockton to do the explaining. There should have been depth telemetry continuously uplinked to the mother ship so they could monitor depth against the expected plan. I guess the carbon fibre was already compromised from pervious dives, and when it imploded, it blew out the titanium caps.
I think the reason the navy didn’t report it as an implosion is because they only heard the sound over top of all the other ships and subs making noise, so it wouldn’t be easy to tell what it was right away
And people like “evidence”. People would be mad no matter what.
It's insane that the exact lesson the Titanic taught the world in 1912 was replayed exactly 111 years later in 2023.
Nope. This was caused by WOKE.
The titan didnt hit an iceberg though
What lesson exactly did the Titanic teach the world? She was so sturdily built that even hitting an iceberg 5 times her size took almost 3 hours to sink her. Titanic was the victim of nature, not stupidity. So much about Titanic is a myth. Smith heeded iceberg warnings and completely altered course to take the ship further away from the primary ice field. Icebergs almost never reach the part of the Atlantic that berg did. And on any other night in history, they'd have seen the iceberg soon enough to avert course, but they got a (1) Calm sea, (2) Moonless night, and (3) BLACKBERG all at the same time. There was nothing inherently unsafe about the way Titanic was operated, and there sure as hell wasn't anything unsafe about her design.
@@josephmontezuma5089 The LESSON
@@allanlindsay72 I believed that too for a while. Watch a debunking video and you'll change your mind.
The alarm thing was genius. Telling you seconds before that you were about to disappear into a million pieces, by implosion. That way, you could imagine it for a few seconds before it actually happened. It is really starting to look like this guy's goal was exactly to have this outcome.
Milliseconds I've read was warning time before failure.
@@stephen8996
If that's true, then it was obviously more than useless.
If the damage builds up over multiple dives, it could work in theory. However, there is no proof that it will always be detectable, and the sensors will always pick up a lot of small cracks and sounds, even on a welded steel hull, so you'd have decide a suitable limit for the detector, and hope that it will still catch real issues soon enough. You could do 100 unmanned dives and monitor the sensors until it fails. Then set your limits to 1/10 of that. They are boasting the simplicity of their design, but choosing carbon fiber is anything but simple.
@@stephen8996James Cameron had a different theory stating they knew it was happening
@@jwstolkIt’s making everyone think of the jet in Hawaii that had made more cycles of compression, decompression than normal because it hopped one island to another far more often than usual.
Jeff, I love how you explain everything and back it up with your research. I'm not an engineer or a submariner, but it was clear that this vessel was not built to anything like the standards needed. Sad for everyone involved and sad that our species is unable to learn from such lessons.
Probably one of the best videos on the Titan I've seen. Explains everything so well with great sources! Well done! So sad that this could have been prevented... but of course, egotistical narcissists were given control of things they never should have. :(
A dearly departed friend of mine was once one of the somber faced ride operators at Disney's Tower of Terror, and he once told me that the cables used to raise and drop the elevator were changed out well before and more often than the manufacturer's recommended parameters. They didn't wait till the equipment was near its limits because they put safety over profits in that instance. The same approach could have saved lives had OceanGate's priorities been different.
Large old companies can't afford to go cheap on safety. That will cost them billions of dollars when fatal accidents occur. New and small companies like Oceangate, however, are under heavy pressure to do it to save money, save time, etc. They take high risks for high rewards. Move fast and break things is the motto. It's human nature that will repeat itself endlessly in various industry throughout history. Look up Theranos.
That sounds quite frightening
@@hightide4782are you stupid? The CEO was literally on the vessel when it imploded
I've never read Jules Verne's 20,000 Leagues under the Sea and cringed through most of the 1950s Disney movie version, But Central to the narrative is the notion of the lunatic Captain Nemo, who similarly puts his passengers at risk in the experimental and highly secretive vessel the Nautilus, which was also operating just beyond any nation's laws to control or regulate. I doubt if this is high on anybody's viewing list these days, but it's hard to portray the captain in a sympathetic light with this contemporary real-world parallel showing what a rapscallion he was.
@@hightide4782 The owner, founder, and CEO of the company also died in the implosion. He drank his own Kool aid and took the risk as well.
I'm just completely baffled at how this man felt comfortable enough to let people down there in it... let alone himself. Really shocking.
I think Stockton was pathologically arrogant. It effected his judgement. Nobody in their right mind would have done this.
Narcissist....
If you whink you can beat the odds and actually beat them multiple times, you become cocky and think you can conquer the world. Never change the winning sub doesnt over the long run. Not a question of if you die but when. Hybris.
A true narcissist doesn’t care about risk. It’s all about “winning” and being right. This time he lost… If he had not been a passenger and this tragedy occurred, he’d be going to prison.
His ego had him deluded.
Very interesting how the sensors patent clearly shows a homogenous and even seemingly unibody structure for the vessel, which may have supported more effective and early sensor responses.
This has got to be the best documented account of this catastrophe that I have seen on TH-cam
As a retired navy submariner.. I've heard no mention of the submersibles' actual test depth or crush depth rating. Nor its hulls life expectancy due to number of depth cycles. Red flags all over this incident. Somehow, this group was allowed to bypass set standards for deep ocean manned exploration.
They only launched the titan In international waters, this was to avoid any country claiming jurisdiction over their activities
And ppl willing to go on it baffles me.
I was only married to a submariner and you couldn’t pay me to do that. Idk how y’all did it.
One word, "STUPIDITY" AT IT'S FINEST😮🤨
It was never certified so I doubt it was really ever tested. According to the men who made the carbon fiber they never thought it should go below 1300 meters and said they had no way of knowing how the carbon fiber would react to 4000 meters one time let alone multiple trips.
@@rachelr8897
What the heck does "ppl" even mean ???
What the heck does "idk" even mean ???
What the heck does "yall" even mean ???
Jeff, excellent video. I am a retired Coast Guard officer who did marine inspections (safety & post accident inspections, and new construction & alterations) on commercial vessels. I worked with the classification societies and for the life of me, I don't know why anyone would not take their recommendations. I know this business is different, but in my years it was do what the class societies tell you, or you won't be insured.
You are aware this company was uninsured?? Because it was experimental.
This is the best analytical explanation of what happened to the Ocean Gate sub disaster I've seen. Thank you
It is so, so sad that the passengers lost their lives due to this narcissistic entrepreneur, Stockton Rush. He was Rush by name as well as nature. Thanks Jeff for a highly digestible explanation of the engineering catastrophe that Titan was. Keep up the good work.
For fools rush in where angels fear to tread.
2:56 It is *_absolutely INSANE_* to me, the lack of safety factor on the design of Titan.
I was a laminator for over 10 years dealing with carbon fibre and composites. The applications were for the motor racing , aviation and marine industries. I cannot comment on how the composite was laid to create the hull as it is not a type I am familiar with. But the conditions in which it was being assembled I am shocked at. It appears to be a workshop/warehouse the door appears to be open in one shot. Hardly a sterile dirt free environment. They also appear to be mixing adhesive in buckets by hand and applying it with plastic car body filler applicators. How on earth will you get a consistent application? How many buckets of adhesive were used and and how did one batch consistency compare to another. If what I was watching was the final product and not some test bed I am frankly surprised it lasted one dive at those pressures.
How about n xray before each dive?
Titan......titanic..errie..fools.
Why not an xray prior to dive..ndt..
Cyclic fatigue....xray
It was probably sheer luck it worked for as long as it did, even one participant on an earlier dive heard a cracking noise somewhere in the hull. IMO this was a disaster waiting to happen. I wonder when the lawsuits for negligence will start. Oceangate company should be sued into bankruptcy and they probably will go bankrupt anyway even if they aren't. The victims families should at least get compensation for their loss of loved ones
You’re channel is great , you are helping me to understand all the technicalities of this sad incident and sad loss of life 😢😢😢
Thank you for a really clear analysis.
I'm not an engineer but worked for three manufacturing companies and can attest that if management listened more to the engineers and the people actually working on its manufacture, they could have avoided a lot of problems. One guy who started his business based on a good idea of his, always listened and he was very successful. He once told me, "if I knew everything, I wouldn't have to hire anyone." Seems like Rush thought he knew everything.
I'm an oceanographer and evaluating sounds in the ocean is incredibly difficult. No one would risk potentially saving people because we thought we heard something. Additionally, and this is incredibly jaded, but this was a great training exercise for a deep sea rescue. So even if they didn't think they were going to find them, there was merit in going through with the search.
Thank you you put it better than I could. You want search and rescuers to be giving all out effort to try and find somebody even if it's a long shot. everyone would be in an uproar if they would have released this information right away and then they found the sub intact a week later because they assumed it was just a recovery operation
Exactly! They needed to exhaust all resources in case the navy was wrong.
That’s what I thought they were doing, a drill.
That’s what I said. This was a rare opportunity for a cool training exercise
Its not fair to the families. Givjng them false hope
I was telling my 8-year-old child about this. I was like you will hear about it when you grow up because in every generation there is always an idiot risk-taker. That is negligent and causes people to lose their lives by being arrogant.l personally think they needed evidence of the sub-implosion for the families particularly.
The more I find out about Rush and his sub the more shocked I am. His arrogance and hubris is amazing.
Jeff I was so pleased to see you made a video on this! The Champlain Towers South collapse also came to mind. The cases are very similar. Thanks for another awesome informative video. Rest in peace to the Sub5.
When I read about carbon fiber, it stuck me that the low of its failure temperature is right around the kinds of temperatures you get when you're just about to come upon the Titanic's wreck. I'm sorry for all the families that lost people they loved but I'm glad Stockton's overconfident ass was also on that sub, as sad as I'm sure it still is to his family. No amount of confidence compensates for even the smallest amount of safety. It takes time for things to be certified as being safe because people who evaluate safety are more the kinds of people who measure twice so they only have to cut once.
Watching the carbon fiber process. The stress is more inward fuel for implosion
Inside the sub is more like just a giant spool of thread. No braces to counteract pressure from outside.
@magsterartabia3889 YOUR second sentence doesn’t make sense: “The stress is more inward fuel for implosion.”
What???
@@electrictroy2010 they coated with carbon fiber the tightness is inward which makes the accident more feasible.
Yes, I agree there is a failure die to temperature
I think it was a legitimate suicide mission. He wanted it to implode and he wanted to be in there.
Similar to how the carbon fiber was right at the temperature limit, the self professed max diving limit was also right at the same depth of the titanic.
Ballasts were old rusty construction pipes.
Controller he used was the one that is specifically known for its connectivity issues.
The window wasn't even rated to go anywhere near that depth.
First dive one of the propellers was installed backwards.
The carbon fibre was bought from Boeing after its structural integrity had expired.
No manual backups.
No escape pod.
Only was able to communicate via text (he would regularly shut off voice comms so he could "enjoy some peace".
He insisted on being present in the sub for every single dive.
Designed it so it was bolted from the outside making it impossible to escape, even if they surfaced.
Made it white instead of bright orange making it blend into the ocean so it couldn't be spotted before O2 depletion even if surfaced.
Chose a cylinder instead of a sphere which is inherently weaker.
Joined everything together with glue.
Flat out refused to do ANY maintenance after each dive.
He only flew in a homemade experimental 2 seater aircraft that isn't even certified or allowed to operate at most airports. [I just learned even some re certified and regulated aircraft are restricted at most airports due to equipment requirements. So last part is irrelevant]
It really seems like he specifically designed Titan to fail, and wanted to guarantee he was on board when it did. I also notices that in interviews with him showing the sub, even he didn't seem to genuinely believe in it. Like he said the toilet on board was the "most popular seat in the house". "You can look out the window, turn up the music (so no one could hear you), put up a blind and uh... its the most popular seat in the house". He said it like he knew damn well that was bullshit.
The sad part of this is definitely the lost of life. However, this tragedy was definitely 100% avoidable if he would have just listen to the safety warnings and red flags. This really breaks my heart.
No it's not. A billionaire is dead that is a good thing.
Hey Jeff, thanks for your outstanding compilation of well researched information about this disaster.
As always, you have risen to the top again to bring this matter down to the understanding of the common person. I trust your perspective on this OceanGate TITAN implosion again as I did when you gave us all the extensive graphical, theoretical, and scientific details on the Miami condo collapse.
From one engineer to another, thanks for a job well done, bro.🙏🏽
Excellent video! Too often there have been warnings but nobody listened until it was too late. My heart just breaks for the 19 year old Suleman Dawood, who was only on the sub because of his Titanic obsessed father he wanted to impress and bond with. A death on the hands of the narcissism of both his father and Stockton Rush. He had his whole life in front of him. Rest in Peace.

Great video Jeff. It should be criminal what the arrogant owner of this company did putting passengers in that vessel. I can’t believe the guy who brought his son with him really understood the risk they took. This incident should be reviewed in every engineering curriculum in the world from now on and make the owner famous but not in the way he wanted.

Isn't that an aspect of the Jules Verne story "20,000 Leagues Under the Sea" where Nemo, the captain of the secret submarine Nautilus operating beyond the reach of the world's authorities goes nuts in pursuit of his own exploratory desires and puts his passengers at risk as well.
Titan was an amazing design and piece of crafted equipment.
Looking forward to the after action report and proposals for development of cf submarines
His name will live on in infamy. History has made its mark on this disgraceful man
Thank you so much for this video. Very clearly explained for the layperson. I'm sorry for his family, but cannot extend any sympathy to Rush, who not only risked his own life, counting on his ability to "MacGyver" his way out of a crisis, but risked his passengers as well. Reminds me of the early history of flight and how many decided to wing it (no pun intended) without a proper machine or training. What a waste.
This is really the only video on this topic worth watching. Thanks Jeff!
Having worked with thermoset and thermoplastics for 20 years as a quality assurance manager, the manufacturing process of the carbon fiber wound cylinder for this application definitely raises some red flags regarding fatigue failure rate. Best video I’ve seen so far on this topic.
Question for you… The use of acrylic on the viewport .. I know that the type the Titan had was only rated to withstand up to 4,000 meters or something like that . But what I’m curious about, is if the acrylic itself is the standard material for that ? And if so , why not something like polycarbonate ? Wouldn’t that be stronger but yet still have that necessary “flex” to it, it be able to withstand the expansion and contraction ?
i am a QUALIFIED boilermaker with around 40 years of experience and even metal has a breaking point if put under stress, i worked underground in South African gold mines for many years and saw what stress and rust can do even to 20 mm thick plates, and even welded it can crack,,, so how can carbon fibre handle so much stress
The titanium caps on both ends were epoxy-glued into the carbon fiber cylinders.
@@eisbeinGermany Carbon fibre is 10 times stronger than steel, but only in tension. It is rarely used for compressive loads as there are better, cheaper, and more tested materials.
This was an untested design, using different materials that all had to work individually, as well as together, perfectly to keep that sub safe. In the end, they will find the different materials separated from each other in fatigue, and the end came quickly as these occupants were liquefied almost instantly under those sea pressures during the implosion.
@@nfurybossnot to mention carbon fiber is also glued together.
When I heard that the Titan was only approved for 4,000 meters and it was diving just under that, I could tell it was an accident waiting to happen. I have absolutely no training, but even I know having a big margin of error is way better than a smaller one.
Wasn't thought out well. Looks like things were rushed & safety ignored.
Well ignorant owner is dead ....this submarine was at best "safely-capable" 50% less than it was rated....
And even that is not safe cuz Carbon and bolts and stretching and so on.....
Thank you for covering this one, Jeff!
Ahh yes I haven’t seen your videos come up since the Champlain breakdowns which I thoroughly enjoyed and this breakdown is even better. Glad to see ur still on it bro!
As a retired Senior Class Surveyor (degree in Naval Architecture and a degree in Mechanical Engineering, Chartered Engineer, CEng) and a lifetime of marine experience including pressure vessels and RV. It proves to me that 3rd party classification of human carrying vessels should be made mandatory.

So with the coal bunkers on fire they set out . No coal anywhere but another one of JPs ships the California was loaded with blankets and coats and announced it's stop position and waited for the emergency... Sleeping through it because the color rockets was different . The original crew left so fast they forgot the key to the binocular case... That key sold for 6 figures...

Next trip an extra thousand tack on...😮
The video of the Mariana trench vessel is interesting. They tested it to 45000 feet before it passed the certification process. Solid thick titanium sphere.
@@Ok_Thanks Stockton's arrogance!
The fundamental design flaw for this vessel is that the designers forgot that "You can't push a rope." All fiber composites have their greatest strength in pure tension. Such materials are ideal for pressure tanks, which have a hoop stress of pure tension. The Titan, however, was not a pressure tank, it was a type of vacuum chamber, where the hoop stress is pure compression, and depended on the integrity of the resin matrix for its strength. Repeated cyclic compression along the fiber axis will cause microscopic separations to accumulate between the fibers and the matrix, eventually leading to microscopic fiber buckling. Fiber composites are highly anisotropic materials, and the designers did not take this property adequately into account. Failure in tension is radically different from failure in compression for these materials. Metals are almost completely isotropic in their mechanical properties and do not have this problem. Metals also have some ductility and will get stronger by work hardening before they ultimately fail. Fiber composites behave more like brittle materials and their fatigue life is not well characterized, especially under cyclic axial compression conditions. They fail suddenly and without warning, even when their application loads them mostly in tension. When the Titan hull suddenly failed, it was crushed by an immensely powerful water hammer powered by enormous momentum which probably turned most of the fiber composite mass into fine dust which will never be found. The underwater implosion of the Titan could conceptually be compared to the implosion of a plutonium nuclear bomb pit like the Trinity 'gadget' (without a subsequent nuclear fission reaction).
A very concise description.
I came here to make those exact points about carbon fibre as a material. Thank you.
This was the info I've been looking for! Dumb question - how much would James Cameron's suggestion of a diagonal weave improve the design? I think it would have increased the life of Titan by a couple of dives maybe, but the fundemental problem would have been the same?
I agree with every point you have made. I've been working with carbon fiber composites and my opinion is that they are absolutely unsuitable for taking any other loads than tension (pull) in axial direction of the fibres. Individual fibres cannot resist compression in axial direction, and so the resistance of the composite against compression along the fibres comes from the resin that glues the fibres together, preventing their separation. Still, it's a "safer" direction for loading the composite than the one across the fibres. Across the fibres there is not much resistance against tension or compression either, and material failure is inevitable in time, even at relatively small loads.
That why a diagonally wowen carbon fibre fabric would have been slightly better than the one that was actually used, at least against sudden cracking. Of course, 400 atm pressure would crumple the diamond woven composite, too, maybe even more easily than the unidirectional type.
They often make expensive instrument cases from carbon fibre composites. I've seen too many failures of such cases, because they are unsuitable against crushing forces.
In case of the Titan, probably even a thick isotropic plastic/resin hull would have been "better" than a carbon fibre composite.
In any case, using metal is the only choice here, I think, because the properties of structural metals' are well defined and their reliability is good. Even with them, regular material check is indispensable.
Elementary my dear… elementary 🥸
Obviously warning systems don't help when you're at the bottom of the ocean and it takes 2+ hours to get to the surface. May they all rest in peace. 🕊️
Thanks for the update, keep the videos coming
Of all the video I watched about this tragedy, yours presented a much more concise and understandable to a layman. And eventhough you are a civil engineer (as far as I know) you still explain it clearly as an engineer, I specially like about your thoughts on “engineering margins” which should have been obvious to the actual engineer of Titan. More power on your channel!
Very concise & understandable - even for us engineering handicapped novices.
My thoughts exactly! I have zero background in engineering, but Jeff's explanation of engineering margins made it so easy to understand the engineering flaws in the design of the Titan. Also when he noted that there seemed to be some narcissism reflected in their promotional materials really rang true, especially when we now know the company did not allow for constructive criticism from within. Another example of corporate and individual narcissism is that Stockton Rush himself was recorded saying that safety was over rated. Too bad the paying passengers were not aware that their safety was not of prime importance to Rush.
Yes a very important lesson on the dangers of toxic narcissism in leadership positions.
I also think of Musk and Bezo going into space tourism
Airport official: "Weather is bad. Don't go!"
Pilot: " I can fly over the storm."
Patsy Cline dies.
The definition of "I'm built different"
Good points. Simple, easy to understand but very comprehensive information. This is must watch video. Thank you sir.
The interview with the father and son combo who did not go made a great point. Stocktons level of risk was much higher than his. Than most. Your point of operating close to max limit is also on point.
I have built some engineering wonders in my lifetime. When buildings that are head scratchers, as to how they don’t collapse, yet remain standing it’s because they are over designed by a safety factor of at least 5 times. I have worked with engineers that go as high as 7 times. The fact that this sub was at or close to its limit in design depth, just blows my mind! And you’re 100% right about the owner being narcissistic.
From the late 1990s up to 2012 I have worked with naval submarine engineers from time to time and no one in their right mind will use carbon fiber or fiberglass for submarine hulls. During the Cold War experiments were done with carbon fiber and fiberglass submarine hulls and they all failed miserably, only marine grade steel alloys and titanium steel alloys has passed the tests with flying colors and the rule of thumb is to design everything to be pressure resistant to a depth of 9 miles below sea level. Of course they will tell you they have a certain crush depth but actually safety marine naval engineering requires to have everything to be pressure resistant at a depth of 9 miles below sea level even though the deepest depth is 7 to 8 miles.
You are correct with buildings that exceeds specifications by 5 to 7 times. The Empire State Building is one obvious example and when someone tries to build an another Empire State Building based on the same engineering specifications it will be 10 times more expensive because it was over-engineered to take a lot of punishments and keeping safety in mind. Now we have marine naval grade structural-construction military toughened and hardened industrial stainless steel alloys that surpasses the original stainless steel rebars used in the 1st stainless steel rebar reinforced concrete pier bridge in Yucatan Mexico which is still standing. With the discovery of concrete additives such as silica dust powders that will dissolve in water so that they will react with the calcium of cement to form calcium silicate crystals that will make the cement-sand mortars and cement-sand-gravel concretes non-porous and tougher and impermeable like glass against seawater and rain water and snow melt just like the Roman concrete in Rome but the secret of earthquake resistant mortar in Haigh Sophia in Constantinople now known as Istanbul today, was already rediscovered in the late 1990s but was suppressed by the construction lobbies in the United States and yet everybody knows how to make it but does not uses it and yet it is so simple for it is just a mixture of equal volumes of slaked lime + powdered bricks + sand and with this mortar it allowed Haigh Sophia to remain standing for more than 1,500 years despite the numerous earthquakes and exposure to the maritime environmental conditions from the Sea of Marmara.
“You are correct” Lol I think he knows he’s correct
Typical aircraft have not much more then 1.5 safety factor
@@robertmikes619- Yes, comparing the safety factor of a building (or any other static structure) to that of a vehicle is meaningless. You don't have those kinds of margins. This fact only makes this company's design approach even more questionable. So sad.
Underwater sounds are very hard to interpret. There are many and they can be hard to position where they came from. There are a number of threads about it from professionals on Twitter. Basically they had to confirm the sound was from the sub before openly stating it was. Saying so early may have caused the search to downgrade and if the sound was something else and they were still ok, leaving them to die. There was no conspiracy, just precautions.
Very good points you make.
But they die on that time when they lost connection so why they did not go to that place on that time. They knew the time and where they were.
@@Crowwillbe Navy heard a "noise" didn t know for sure then, what was. Relayed to C. G, & they assumed it was from implosion, as was th time lost contact, signal. C. G was searching over Titanic site, but it takes 2 hrs to get to bottom, & was nothing available, fast, till got th robot to go to bottom .
Thank you so much for your very interesting input and expertise into this tragedy, I am learning so much listening to your channel, which I have not long been a subscriber.
I absolutely love your knowledge and your in-depth explanation of the entire situation. I also believe everything breaks down over time, and the Titan was no exception.
I imagine they were hearing horrific creaking noises just before the implosion. There had to have been physical indications. They knew that something bad was happening, but even if they were able to abort the dive and start heading back up, there were at least a few kilometers left to go up before the pressure acting on that craft would have been low enough to save themselves from the impending doom! Imagine the panic. Imagine that kid who said he was terrified of going on the dive with his father. An asolutely horrific and unnecessary death!
the sub had sensors on the pressure vessel
I agree…I think they heard the noises as they descended. And no escape possible…bolted in.
I hope the captain had time to say “I’m sorry.” to his ‘crew’ of unsuspecting passengers.
Excellent video. James Cameron reported that hydrophones heard pops, clicks, and snaps before the hull collapse. They were so loud that the crew heard them inside the vessel. They dropped their ballast weights and began an assent, then the hull failed.
you don't know that.
@@buckmurdock2500 99% sure that is exactly what happened. The hull delamination took a few minutes, and the submersible community are all talking about the hydrophone data.
New subscriber, thanks for the content. I found your video interesting informative and entertaining.
Really interesting getting the insight of someone like you. Great video
I am really struggling with this story. I have wept for that 19 year old boy today. I cant imagine the fear and regret he experienced. His death should never be forgotten. He was just trying to be a good son for fathers day. Its beyond sad.
He didn't have time to experience 'fear and regret'. Fear, yes, up until the implosion/explosion. Regret, no. You should read the audio transcript between Titan and mother ship. Someone had explosive diarrhea in the sub and sounds of disgust were heard. So more than likely they were distracted dealing with that and not paying attention to the mission and alarms, if any.
His dad was obsessed w/ Titanic, he wasn't aware of technical difficulties,( tho all signed waivers, w/ death clause possible) th others were experienced,French diver been to site, 37 times, British billionaire, Hamish Harding, world wide adventurer, been to Mariana trench,
Yeah, that's the worst part. Poor guy didn't even want to be there. God bless him
@@jbsimmons54What?? Troll.😂😂😂
@@afonphoenix16what exactly did he say? That comment was unfortunately deleted
As an engineer myself, what I also find tragic is that they almost only hired young freshly out school engineers that obvious didn't have the experience needed to handle such design. It's not their fault you know close to nothing when you graduate, so you need those old knowledgeable engineers. Now imagine having that on your CV 😕 it will also destroy some careers.
it did work once, then it should of been binned.
Correct, aside from the impact on career, I wonder about the emotional toll and guilt these young employees will have to deal with.
Get woke, go broke
Was it a “move fast and break things” kind of shop?
He ended up hiring a very young woman. BIG mistake 🙄
Theoretically, the mother ship probably also had a SONAR on-board that could have possibly allowed them to be aware of an implosion, but the conditions would have had to be nearly perfect depending on the vessel's depth. The reason for this is that as strata in our atmosphere certain conditions allow for the skipping of radio signals, underwater we have these strata that consist of differing water conditions such as temperature and eddies. These can very effectively allow for sound to transmit horizontally, but not vertically. The SONUS array sit at varying depths and at nominal intervals in order to pick up underwater activity.
Great video!! So well researched
During this video, pictures of another father and son flashed up.
They were planning go on this very dive but just a month or so ago they decided not to because the son (20 years old) had severe misgivings about the safety.
You would have thought that the younger man would be less concerned about risk of danger because he has had fewer near misses in life. You know the old saying "Good judgement comes from bad experience".
Wish they had trust their instincts. An unnecessary loss of life. It really looks like a toy to me. My goodness, does it get any worst than that?
@@tomparker9966not these days. Many younger people are more safety conscious and generally unlikely to just accept what they're told. At least partially because of the immediate access to information that we have now
I gotta imagine Rush dismissing any alarm warnings or groans and creaking from the ship as “that’s normal and to be expected.” He did that with too many things. Experts said they occupants wouldn’t have felt or known what was happening. An implosion at depth is just too fast. Faster than the any pain signal. Faster than the sensory signals from your eyes. They were gone before they knew it.
Someone here said was tested in thBahamas, twice, & was creaking, cracking then, yet went to Titanic site, 3 dives . so was weakened w/ each, .. not proper maintenance ..
That's the only comfort there is in this tragedy, most likely they never knew what hit them, at least I hope that's the case.
Good for them
The creaking was the carbon fiber hull being fatigued.
@@jeffk464 the creaking was the sound of their moms moaning while I bust in her face right before the sub implodes and flattens everyone inside
Subscribed after the Miami condo collapse. Love the knowledge you bring to these events. I agree, I wish we would learn and listen to the warnings.
Thanks , you made this accident understandable to someone with no understanding of engineering!
"Why did the navy wait to inform us they heard the implosion" the ocean is a noisy place, the navy needed to confirm that it happened,in the meantime they still continued rescue operations just in case it was false. Just reference the USS threscher, rescue was getting confused due to other rescue ships/personnel
I wonder what it sounded like...
probably needed evidence for the families before opening their mouths.
Even if they knew 100% for certain than it imploded, they still would want to locate and collect the wreckage if possible. Some agency or another is going to want to examine the craft to find out why it failed, and prevent a similar failure in the future.
The search and rescue protocol followed was the correct approach. It was unlikely the craft was intact or that there were any survivors, but it was not certain. Once evidence was found that removed the uncertainty, the search was called off and the mission went into recover rather than rescue mode. If it were my loved ones on that vessel, I would hope for no less.
Maybe that underwater listing system they heard it with. Wasn’t really known about.
Or what areas it’s listening in an or how sensitive it is. Maybe that was accidentally brought to light by someone that knew about it in the navy that was aiding in looking.
Which made it not hideable as previously was to keep it quiet as possible. But maybe it was mentioned but originally passed off as. May of was that. But hard to say. To play off how sensitive it may be as a listening tool. Who knows.
I just want to say I love the way you explain things so that laymen like me can easily understand. You've done a great service here, and your thorough investigation is apparent. There is so much BS circulating out there right now and your channel is that breath of fresh air.
Good job very good job 👍
Great Video! Thank you!
Safety in any field is a compulsive, objective and rigorous process. As a retired anesthesiologist I fought safety issues in operating rooms for almost 40 years: laparoscopic surgeries in the early 90's where no one gave our anesthesia department any advanced information that surgeries would be conducted with laparoscopes instead of the usual incision/open type of surgery. That happened again when robotic surgery came along. Anesthesiologists who complained or delayed surgeries were castigated--usually by CEOs who had surgeons complaining about time-wasting issues. Another time a hospital changed out our anesthesia machines over the weekend only to have us show up for Monday surgeries with machines none of us knew how to use (An anesthesia machine is the device which monitors patients' blood pressures, heart rates, mixes oxygen and inhaled gases, provides ventilator support for patients, etc). Crazy stuff. It still goes on: Michael Jackson and Joan Rivers can tell you all about it.
Thanks Jeff. I’m glad TH-cam recommended your video. I like the way you don’t try to sugarcoat their deaths by saying there is a possibility they knew what was happening. all too often the main stream media always tries to minimize the suffering of the victims in horrific tragedies like this.
Agreed. This is a good example of a situation where no waiver should remove liability. Just because they signed a waiver does not mean the company should not have a duty to engineer in a professional manner by preventing foreseen risks and establishing a safe method of operating the vessel as its design allows. We know the vessel was not properly engineered based upon the lack of nondestructive testing and non-rated components, over which their safety engineer was fired upon protesting.
The Boiler and Pressure Vessel Code no doubt prohibited their mode of operation. The NASA guidelines for a vessel used a small number of times is a safety factor of 2. A small number of cycles might be 1 for something that goes to space or sea floor, especially without reinspection. Else you might use something closer to the BPVC safety factor for bolted connections: 4 as far as I could find. They also did not inspect even once and had a safety factor of about 1.05, which further diminished due to fatigue. That is a case of homicide with malice. Negligence would have been forgetting to calculate and inspect, as opposed to willfully failing to do so or deliberately ignoring the need to do so, which is malice aforethought.
A waiver should indemnify only if the safety precautions taken were reasonable, or intentionally forgone by the participant, not the company without their perfect knowledge. Then only if the task is inherently at the participant's own risk, like extreme sports. Not like extreme safety of life critical engineering, where inherent hazards are guaranteed to eventually kill or maim if not prevented. Especially where the calculations were performed and weren't going to rate the vessel for long term service and the materials and methods were found wanting.
Guy didn’t want experienced submarine guys on his team the same way that Elizabeth Holmes didn’t want medical technology people on her board of directors.
@@RebeccaOre Oh welcome to my impromptu TED talk...
I know a subject matter expert who predicted the fall of Theranos as an industry insider because of the mathematical nature of blood samples.
Concentration of a substance in blood is Poisson distributed random, more random at lower concentration where there is an ever larger probability of too few or no particles in the sample as it gets smaller or more dilute.
While a relatively abundant small molecule, like sugar can be measured with a finger prick, a larger particle in lower abundance, like an HIV test in a well treated patient or a cancer test cannot be done with a small sample.
So he may have discretely told some investors to sell before they had to sue. I think there is a pattern to this, anyone who rejects expert opinion without being another expert is one SEC filing away from a lawsuit.
As a pilot (I don’t know what his experience is) he should have been far more safety conscious. Safety is the number 1 concern for pilots which is what our passengers expect.
It's not his first time to drive experimental things, means all his life he is playing with his luck, not safety or knowledge, I knew some people are like that, rich, high ego, spoiled and keep testing their lucks and thought they are good, but it just their luck, thats why he think safety is a waste since he never care.
I agree with you. Your my 1st level of security. If you don't feel secure of what your piloting then it shouldn't be used.
I also hope it happened without them knowing about the impending disaster. RIP
and i’m a student pilot. you would think that they wouldn’t been more safety conscious considering submersibles are subjected to pressures much higher than aircraft
As a pilot... means nothing. What do you fly? Flight Sims do not count.
Fantastic information! Thank you.
Glad it was helpful! Jennifer!
Very informative! Thank you! 👍
Jeff is perhaps one of the clearest engineering commentators on TH-cam...he is absolutely brilliant in taking the complex and making it simple and digestible for the masses. Jeff, thank you SO much for what you do.
I cannot agree with you more.
I know nothing of this subject, let alone engineering as a whole.
Absolutely nada damn thing.. but I understood everything he explained in this video and am actually more interested than I was before about how this tragedy could have been prevented.
Worst thing about this is that Rush was a pilot around when the DC10 were crashing due to improper maintenance,cargo door,etc. You would think that he would have brought the same safety concerns with aircraft as with submersibles.

Great presentation. Thanks.
Thanks for your insight.
Knew it was implosion the moment i saw how long itd been under operation with the same carbon fiber hull. The 4000m hull is believable, ONCE, after that initial dive every dive thereafter would dramatically reduce the strength of the hull with internal delamination caused by the cycling fatigue like you mentioned. My company makes composite components for automotive racing applications and we have pretty strict replacement cycles for components subject to downforce syress, i cant imagine being the company that was commissioned to make the cylinder for the pressure hull and knowing it was to be used for passenger carrying and still greenlighting production of it.
Also. Dont know if you mentioned it or not, in multiple of the videos of the interior the monitors and equipment they use look like theyre drilled and bolted into the pressure hull, causing many weak points that the already compromised hull could have avoided by using panel bonding epoxy
that was their first dive down that deep. all other "tests" were within 1300 feet down. what it was rated for. it never made it to the titanic because missions 1-4 were called off and they just did tests on those missions to 1300 feet. Also yes, you're right, the equipment was drilled into the hull. making it compromised as they basically destroyed any of the benefits of having 5 inches of carbon fiber.
As far as I can tell, the monitors and other items are attached to an interior lining, not the hull itself. You can see it when they show the sub with the door open - it appears to be a metal mesh. But then, why? First, the LED lighting is hidden behind it, so that if something goes wrong with a lighting unit, it is inaccessible. Second, it seens to eat up around 4 cm of precious space - they could have made the hull diameter 8 cm smaller instead, increasing strength, if they didn't need that room, or added insulation or safety padding instead. It also means the inside of the hull is not visible to the crew, and can thus not be inspected for any visual changes.
I not sure if I'm reading your comment correctly..but from what I've gathered watching, dozens of videos on the subject, the vessel had been down to the same depth as the Titanic a handful of times. Unfortunately once too many.
@@bobashalak871 Nope. that was their other vessels. this one was a brand new experimental vessel. this one never saw below 1300 feet before now. they have a bunch of real vessels that they use to take people down made out of conventional stuff. this was their celebration experiment.
@@bobashalak871 every other mission was called off due to water problems and damage problems. so they could only go 1300 feet down to show it off to the guests.
I have been a competitive sailor, and around boats from childhood. When an angry swordfish or whale can tear apart a 'gel' hull, or even oak plank, you gain new respect for pressure on materials. I am a retired architect for commercial interiors. Many sympathies to these families and staff. -R.

Thanks Jeff for again doing a thoroughly researched video on another disaster. It is sad when people ignore safety factors in engineering. The viewport being only certified to 1300 feet should have halted any dive to greater than 650 feet.
