Just to let you know. The video titled 'Coast Guard Video: Titan Sub Salvaged Off Ocean Floor' seems to be corrupted at about 12 minutes 30 seconds in.
HEY JEFF how ya enjoying the 100 grand you made off that FAKE "transcript" video from last year?! haha you made a sucker outta each and every one of us!
@@borghorsa1902No.. he means that Boeing are infamous, especially since the McDonnell Douglas merger, for prioritising profit above solid engineering. The recent 737 MAX fiasco is all you need to know when it comes to how Boeing operate these days. So his point was, simply, that it’s painfully ironic AND concerning that Boeing didn’t want anything to do with the Titan sub, given their track record.
I remember in a business law class learning that gross negligence is very hard to prove, because you have to prove it was done consciously and deliberately, and not just someone being ignorant of a risk. My teacher's jaw would have hit the floor seeing this absolutely flawless example of gross negligence.
I was telling a friend about all these findings. It's like every step of the way, from the business side to the scientific/math side....there was absolute negligence. And it was driven by Stockton Rush and reinforced by the people who chose to stay. It's mind blowing how bad this is. It will be a business case study for a long time.
@@puzzlechick163 remember there was a 25 page document that highlighted it all that SR sued David over in Court, it's all documented he bullied people into getting his way, money talks with these type of people.
Any time there’s lack of oversight, this garbage flourishes. I’m still somewhat gobsmacked that 2 billionaires looked at Rush’s operation and Titan, and gave it their seal of approval. They probably thought “Hey, if P.H. is here, it must be fine.” It’s one of those moments where commenting a lot, or not at all and a SMH, equate to the same result.
..and it utterly fascinates me. As someone who has shopped for carbon-fiber bike parts, I am was surprised by the outcome of this venture. I only wish I knew about it before it happened. Ignored the news cycle at the beginning (drop-release of information annoys me) but am glad that we have even more info in this past week than what we had a few months ago.
People talk about the fact that nothing was certified, but that alone wouldn't have necessarily been a big problem on its own. There is one other deep sea submersible tour company that I know of which doesn't have any certification which has been operating for longer with no significant accidents, and the owner of this company, Karl Stanley, has gone on the record to say that Stockton Rush consulted with him and sought his advice on various things, but ultimately IGNORED most of his advice! All accounts point to Rush frequently ignoring advice from people who were more knowledgeable and more experienced than him. He's actually been in the Titan sub before, and there is a great long interview with him that you can find here: ua-cam.com/video/n40ukuk9Ay4/v-deo.html&t Karl Stanley and his company was something of an inspiration to Stockton Rush, but this other uncertified company still has taken far more precautions, and never tried to go anywhere near as deep, or take anywhere near as many risks with a new submersible design, than Stockton Rush did.
Watch Mission Specialist Fred Hagen's testimony on September 20. He, too, was personally very impressed with Stockton Rush. Mr. Hagen insisted that he be allowed to go down in Titan's first dive to the Titanic in spite of earlier awkward "incidents."
Not to mention that even if both were being completely honest, they'd still likely give conflicting testimonies. That's just the nature of human memory, especially for stressful situations, and after so much time. Even two people in the immediate aftermath of an event with nothing to hide will give conflicting testimonies. Still, David is certainly the more credible testimony of the two.
@tomr6955 David lockridge has no vested intrest in the company nor can he be made liable. Renata Rojas on the other hand was an investor in the company and friends with the CEO and she was on the PP ''helping out'' when the accident happend. I would say Rojas has is pretty biased for those reasons and was obviously less than truthful with her statemens and purposely ignorant, because when u are under oath ignorance is bliss.
@@salland12 She was entirely clueless as to why DL kept asking Rush for the controls? "He got us out of there in one swoop ... very skillful" i.e. admitting that Rush screwed up?
My father in law went to high school with Rush (Phillips Exeter Academy in NH), and said that he was always like this. He played on the same sports team with Rush. Said that Rush used to miss practices and demand to be first string. Rush would lose them games by trying to play as if he was the only person on the team that could do anything, all for his personal glory and not a team player. Rush would lose them games and then berate other players that it was their fault. He said that they all assumed that Stockton's parents donated enough to the school to keep him on the team.
Watch Mission Specialist Fred Hagen's testimony on September 20. He, too, was personally impressed with Stockton Rush. Mr. Hagen insisted that he be allowed to go down in Titan's first dive to the Titanic in spite of earlier "incidents."
Boeing, who isn’t even in the submersible business, saying “In our opinion you need 10 inches” and Rush saying “Nah, 5.” is probably, for me, the #1 datapoint telling me he was psychotically focused on cost above everything else. Datapoint #2 would be that underbed plastic container he called a “scrubber”. And of course, we now know that he had employees forego pay a couple times to keep the ramshackle operation afloat. He was probably near desperate by the time that last “expedition” left the dock, which is always a great mental space for your pilot to be in as he pushes you under hundreds of atmospheres of pressure with no means of abort or escape.
The part that upsets me the most is that Stockton never got to know how wrong he was, or what the consequences of his actions were. If only we could turn back time and show him these images of his crumpled up sub at the bottom of the ocean.
I doubt the "red mist" which comes over us as we listen to the ill-conceived Titan idea, build, and OceanGate's unprofessional business practices, etc, would reach Rush's eyes prior to implosion... We learned and are saddened by Rush's hubris and incompetence, but he died barely milliseconds before the evidence swallowed him up within his mangled "dream machine"
He still wouldn't accept it. Even if he saw those images of the imploded sub, he would find someone else to blame or argue off some stupid technicality. He was too arrogant and egotistical to ever accept his wrong.
He would never believe it. He would find a way to put the blame on anyone else. His ego was too big and too fragile, and he was too greedy, to accept his own failings.
David Lockridge is by far the more believable witness. He showed up without a lawyer, she didn't, the story was basically the same except the pieces that would make Stockton look bad, what Lockridge said was on par for his personality based on several other witnesses, her version of how he handled it wasn't.
Watch Mission Specialist Fred Hagen's testimony on September 20. He, too, was personally impressed with Stockton Rush. Mr. Hagen insisted that he be allowed to go down in Titan's very first dive to the Titanic in spite of earlier awkward "incidents." Lockridge obviously has a deep dislike of Stockton Rush.
@@Gravitys-NOT-a-forcehe has a deep dislike because Stockton was masquerading as an expert in the field that DL actually is an expert in. He was hired to ensure a safe operating environment and was fired when he attempted to do that. Stockton was an egotistic narcissist who played Russian roulette with everyone’s lives. Including his own. Whether a wealthy man with zero training or real, deep knowledge of the system he is a passenger in was “impressed” by Stockton or not is important. Fred got lucky. That’s it.
Narcissists employ their fans or friends to do the dirty work for them, her testimony came off as too defensive, she was more hurt over the fact that Lockridge said she had tears in the eyes and was scared than that Stockton killed all those people. Never trust unbiased sources. Let's hear the testimony of the other members of that exact dive.
Memory isn't flawless. but David looks like the type of guy to literally write the events into a notebook as a precaution for investigation. She instead looks like she may have recoloured her experience and memories with her subsequent interactions. It's possible Stockton didn't throw the controller and it was a subsequent nightmare or something that changed the given testimony. But the key facts? Such as the refusal to hand over the controller? Probably valid.
I was in communication with the admissions department of MIT twice. I visited the campus but never attended or graduated. I did go to Harvard, though. In one end of Harvard Yard on out the other.
David Lochridge's entire testimony was fascinating. To me it seems like he truly did everything within his power to prevent this from happening. I wonder if anything will happen to OSHA after his testimony.
nothing will happen, maybe some ammendments to some obscure rules and procedures, but OSHA will just walk away with a slap on the wrist, that said the documentaries will probably paint them in a bad light.
Ms Rojas's testimony came off as defensive, she seemed more hurt by the fact that Lockridge said she was emotional and fearful with tears in her eyes than the fact that Stockton killed 4 other people and himself in the last dive. The fact that she's a close friend to the family makes her testimony questionable, she also omitted the part where Lockridge was hit in the head and only picked the parts that would not implicate Stockton so much, such as Lockrdige asking for controls, taking over the control and maneuvering out of the bad situation - these are all true, however, that is selective testimony which contradicts Lockridge's account. So, one of them is lying about exactly what happened, and anyone with more than two brain cells can see who.
She might of had Explosive Anger, blasting Rush to hand the controller to the other guy. ( Those Extreme Anger Episodes can be Compartmentalized from the personality shown in public). Very common..

@@peabody3000 , maybe if Stockton had not DIED on that last dive, I'd be quiet. He believed in the Titan, the engineering that went into it. Listen to Fred Hagen's testimony on September 20.
@@peabody3000 , you think this is a dedicated 'Trash Stockton Rush' site? The Titan HAD made 13 successful dives to the depth of the Titanic. Each Bell Boeing V22 Osprey aircraft costs $84M - and they still crash because of engineering design failures.
Safety was never Stockton's M.:O. and he cut corners everywhere he possibly could. So, my hunch is that Stockton set the guidelines to 8600 metres deep ( , not so that he could have a high margin of safety. Rather, so that he would have a high margin of corner cutting. This is how I think he eventually arrived at the 5" thickness specification. Stockton figured that if they recommended 10 inches for 8600 metres, then half the thickness should work for half the depth. Which in his case would be the Titanic Depth. An idea like that is something Stockton would have come up with.
I majored in English, so engineering is far from my area of expertise. However, I don't think decisions like this seem sound. I imagine pressure might increase exponentially or carbon fiber require a minimum thickness, etc.
Woven Carbon fiber cloth, epoxy resin... they share a solid state overlap but it doesn't have molecular granularity like a metal alloy's crystal lattice. I think epoxy is an amorphous solid, a polymer. And Carbon is a crystalline solid. Those two kinds of solid diverge in their property and behaviour. This obviously implies the integrity of their composite strength diverges as the two go their seperate behaviour ways along unequal material properties paths at seperate solid state intervals making the laminar yield strength a bit of a mirage and more or less disposable after use.
@@santyclause8034 it definitely had a limited number of dives and it was Rush's job to figure that out. He either failed or didn't care relying on the RTM system. He was listening for separate strands to quietly break when in reality they were getting gum blasts from the first dive.
If what Lockridge said isn't true, then why was she so impressed by his ability to maneuver out of a situation? If there was no situation what would there be to be impressed about?
I hope she's found guilty of perjury soon, as she's lied and put David down all for Oceangate because she's besties with the Rush family, I honestly hope their all held accountable as they all knew about David refusing to go in the Sub and asked him to redact his list of faults and concerns etc, it's just absolutely disgusting how they all choose to ignore it and kill all those poor passengers, it's like SR had a death wish!!,
We’re REALLY seeing a problem of people who decide they want to be famous geniuses and then decide how to do it. True geniuses are just interested in the subject and do most of the work themselves. The fake ones dream up impossible ideas and hire others to do the work, but the best they do is incremental improvements not the major breakthroughs promised. Ideas are the easy part. Making them work is the hard part. Elizabeth Holmes wasn’t a scientist. Elon Musk isn’t a rocket, car, or tunnel engineer. Stockton Rush couldn’t design subs. They just wanted the credit for other people’s work yet their only skill is talking rich people into giving them money.
I did some back-of-the-napkin math based on the table at 12:10 in the video. A 9.3 in thick hull gets you to a max depth of 8600 m @ 12562 psi. Assuming a linear scale, that comes out to 1350 psi/in of hull. At 3800m, the psi is 5389. This means that with a 5 in hull at 1350 psi/in, the Titan sub had a max psi of 6754, or 4700m. This is a safety margin of 1.25. Meaning the subs max rated depth was just 25% more than its operating depth. This is a crazy low safety margin, as others have highlighted.
I'm so utterly curious what Stockton's planned lifespan of the hull was. Recorded dialoge lines kinda show that that's what he was trying to figure out, but when he got extreme and unexpected readings from his own vessel monitoring system, he was so weirdly confident in his sub he just dismissed it. It's almost as if he was just expecting it to leak a little bit, never actually implode. But there's no shot he was that stupid...it boggles the mind Edit: I forgot money is a thing and apparently oceangate was basically destitute so...I guess that'll do it?
@@skeezixmccatI’m convinced Stockton KNEW when those readings came through that Oceangate was doomed financially. And maybe he had some life insurance or something that he wanted to ensure someone got, so he ended himself in a way that would ensure the money was paid out. That’s just my theory though.
Aye there's the rub, the relationship between depth and pressure is not linear. It varies with the temperature of the water column and not in a good way.
Your assumption of a linear scale is actually too conservative. Besides pure compression, the tube also experiences horizontal bending. A reduction in hull thickness increases bending stresses by the square of the thickness and deflection by the cube of the thickness. Therefore, halving the original thickness increases bending stress by a factor of 4 and deflection by a factor of 8. In reality, the actual stresses increase somewhere between linearity and the square of the value. To accurately model the shell, you need a finite element program. The mode of failure is primarily due to the difference in stiffness, not just the material properties at the transition ring boundary. Titanium is not only materially stiffer than delaminating carbon fiber, but the half-spherical shape is also much stiffer than a tube. Consequently, it deflects less under compressive loads. This difference in deflection caused the ring to shear off under cyclic loads.
Still can't believe they would just grind down the carbon fiber if there were bumps and add another layer over it... You just broke and removed layers of that fiber, making it weakened there
The bumps were already a weak spot. The bumps are slacked fiber, which would never go in to compression or tension at the same time as the surrounding fibers; meaning those surrounding fibers experience excess load the slacked fibers should be carrying. And that's the problem with flat-braid fiber on a radial form. It's never going to lay flat. Half the fibers will be in an interior bend and half will be in exterior. Any kid who ever covered a ballon with papier-mache has seen this. That's why you don't use it in an application like this, you use a cast material. Grinding the bumps down didnt make it any weaker than it already was, it simply truncated an existing weakpoint layer to layer. The design was a weakspot. They took a tension-reactive material and square-peg round-holed in hopes it would alchemically convert to a compression reactive material because Stockton's ego demanded it. It wasn't even for cost. They spent so much building and testing his hairbrained idea, and having to build another cause it wore out so fast from cyclic fatigue that had they just made the god damn thing out of titanium in the first place, they wouldn't have had to test as much, would have had a better idea of reliability, wouldn't have had to scrub multiple 'excursions', and externalities would have been more content to sponser or associate. The company would have likely not been so strapped for funds, that there probably would have been enough money to pay employees and also upgrade the plastic tote based life-support systems. It was all an experiment for Rush. So twenty years from now he could claim 'i was the guy who said carbon fiber had a place in commercial submersibles". And that killed his company, killed his clients, and killed him.
@maxdecphoenix So take Stockton's name in vain or even Darwin's (for his stupidity). No reason to take God's name in vain and use it as a cuss word for man's ignorant and prideful decisions.
All that was missing in all of this disregard for safety was excessive amounts of duct tape being wound over the glued titanium rings and claiming that it's highly reinforced.
Your coverage of this event is absolutely incredible. Thankyou so much for all the effort you have put in compiling and the testimonies and adding in the context. I’ve watched many videos on this event and yours are far and away the best. Please continue to cover the story.
I think Renata lied her @$$ off. If possible we need to find who else was down on that dive, did they testify or make any public statements, if not, can they be reached for comment ??

You write the same thing in every comment you do. Why? If You are a human, you believe in lies and are telling lies imo. Just stop defending that maniac when there is more evidence against him then the other way. Stop being ignorant! @@Gravitys-NOT-a-force
Stockton is a narcissist: narcs get worse with time, their delusions about their grandeur and abilities increase, lies about their achievements and intensity of the advertisement of their imaginary achievements increase, their temper worsens when they face criticism, their attacks on their critics increase, the control on everything intensifies, name-dropping and lies about connections intensify.
I think I know why the bed liner was used on the exterior. It hid all the imperfections in the hull visible when looking it over as I am sure all the people who traveled in it and viewed it out of the water. This led to a false sense of safety and security... What a shame and waste of human life.
There is an old saying... "Manners maketh the man" ...in this case (or so it seems to me - and _I'm absolutely_ _no expert_ in _any of this_ ) " _Money_ maketh the mad, sad, and _dead_ adventurer" ...both Rush's money problems - the lack thereof etc - and the multimillionaires / billionaires (whichever) "having more money than sense", being duped into _believing Rush_ over the safety of Titan, and the fascination and draw of Titanic, who can be seen in _great detail_ on video since her specs have been so expertly scanned and reproduced digitally for _Everybody_ to see as they view her on their handheld devices, with absolutely _no need_ to dive to such crushing depths to see her in all of her "rusting glory". "Safety is a waste", is it Stockton...? I wonder what Wendy and the rest of your family think of that idiotic boast now?!
Well, it did protect from external damage. Have you ever had anything that is made of fiberglass or carbon fiber? Let's say you're moving something and it happens to hit the submersible. Now you have a scratch, ding, or worse that can affect the integrity of the structure. It's not unlike how it protects the bed of a truck.
I think the "bed liner" made engineering sense, but Stockton should have had some way of scanning the hull after each mission, perhaps some acoustic-based machine - ultrasound ? - to detect cracks or anomalies. Not performing such a test was irresponsible/insane.
@@entropywizard someone like stockton would have rationalized the data away every time, no matter what, no matter how damning. and the bed liner sounds reasonable but it was never tested for this use. and if it isn't tested, it's merits are unknown, simple as that. overall it's a great illustration as to why narcissists should never be trusted.
@@entropywizard , it seems that Stockton had no scientific way of checking the integrity of the wrapped composite-fiber hull. That was serious negligence. But the Titan had made 13 successful dives to the depth of the Titanic. Stockton, evidently, had made a serious effort to interpret the cracking sounds made by the wrapped hull. Obviously, his interpretation of those cracking sounds was faulty.
That submersible was never beautiful. It was dangerous childsplay by a wealthy ego wanting a bigger reputation . Stockton Rush should have been the only one allowed to play his fantasy games in it and the only one to succumb to it's ultimate death sentance. And... getting locked inside the ugly beast with no way out from within is a ghastly suspension of good judgement. The whole thing was a sham. And YES more of your great analysis and breakdown of the proceedings!
I have never gotten over the fact that they used old pipes as drop weights. And the fiberglass viewport. And that people sat on the floor. It was like something someone built with legos and then called it "beautiful"
What is sad is he found people gullible enough to not only get IN the darned thing but think it was going to take them down to the titanic and PAID for their death. How can someone be THAT rich and be THAT dumb ???
@JustJesstheMess I thought it was a madcatz but no you're right it's even worse it's a Logitech 🤣 because who hasn't had a Bluetooth device totally disconnect and refuse to reconnect for God knows how long 🤣🤣🤣🤣
This reminds me of the “Tragedy beneath Boston Harbor In 1999, two divers died deep in a 10-mile-long Deer Island sewer tunnel. a “hotshot engineer” whom the contractors had hired came up with a plan to mix liquid oxygen and liquid nitrogen and turn the mixture into breathable air. “The disaster was described in the 2014 book Trapped Under the Sea by Neil Swidey. The book tells the story of the divers and the events that led to their deaths, including the removal of the ventilation system and the use of a makeshift breathing system.”
Even if Renata is not consciously lying or covering anything up, the human memory is not perfect, if she paid a lot of money, had built these dives up in her mind as exciting events, and made friends with SR (biased to view him favorably), it's only natural she would look back with rose colored glasses..

This is one of those stories that might get told in engineering school. The most important thing a young engineer should take from this is try not to make yourself compromised if you were to need to walk from your company. I have walked and it is extremely expensive to either resist until fired or resist and get bullied out. I lost about $200,000 a few years ago walking from something I was morally against. Buy half the house you can afford, buy good used cars and take good care of them, limit child count and learn about narcissism and avoid company heads that are that way. They will kill you to keep from being embarrassed.
Well, he did get his interior lights from Camping World, so you know that he overpaid for all the other parts too. This design would make Wile E. Coyote blush. "You know, at some point, safety is just pure waste."
Hey, now. Wile E. was a super genius and always got his stuff from the amazing Acme Corporation. There was nothing sketchy about his designs. It was just that the Roadrunner maxed out his luck attribute and no amount of design could overcome that.
Thank you for your excellent work, Jeff. Best coverage of this tragedy I have found. I also love it when you tone down your voice when presenting these testimonials. Makes the whole thing like witnessing an Alfred Hitchkock thriller.

Keep the vids comin'. Your opinion and things you point out tend to be your own. Other videos I watch are all the same things we already know and no educated opinion so please, if you have more, give it to us.
I wonder if anyone else was on that dive along with the 3 of them. It would be interesting to hear their account being as David and Renata's accounts differ significantly.
There was that other young employee who's accounts were very similar. Anytime she questioned why things were done the way they were, it was all handwaved, and she was told by her supervisor/manager that she shouldn't be questioning things and that her behaviour didn't "align with the company" because she wouldn't just be a yes-man. Sounded like a very toxic work environment all around, top side and all.
What a shame that Stockton's arrogant stupidity got other people killed besides himself. I get really sad when I think of that young kid that died as he did not have enough life experiences to know he was in mortal danger.
Really first rate presentation of a difficult subject - thanks for spending all your time looking for the information and comments we all need to hear!
There are a few key players not being questioned. One is Wendy Rush, she was responsible for for the social media hype, and she was on the Polar Prince on the fateful day. Board members are not being questioned. Why not? Its very suspicious.
Maybe because they will be defendants in upcoming court cases, they don’t want to implicate themselves at this hearing. Their lawyers also might have advised them not to.
One detail you missed on the original spec sheet was cures per inch on the hull. The original plan was 2 per inch instead of the 1 per inch that they ended up with, they definitely would’ve got some reduction in voids with the extra cures. But autoclave time was just too expensive for rush. Seeing all these details and considering how many dives the titan lasted almost makes me think that a well engineered and thoroughly tested carbon fibre hull could’ve worked really well and rush could’ve been seen as the innovator that he thought he was
Agreed. The fact this thing was able to dive on the Titanic so many times given the soddy quality of the lamination and glue joints really speaks to the resilience of the material. The hull monitoring system did a good job as well. It clearly showed a major shift in hull layers on the prior dive. At that point it should have been decommissioned.
Composite materials, woven carbon ply amorphous solids and aggregate cementing bonds, does not destruct in nearly as predictable a failure as crystalline solid matrix. Doesn't have overlapping state equilibria like metal alloys (alloy lattice structure solidifies/quenches within a given thermal phase equilibrium window of overlapping state). Failure under loads like the Abyssal Deep is clearly going to escalate non-crystalline composite laminate to yield point strength failure in catastrophic fashion. Which is a long way from alarming and scary signs of danger with safety margins of moments to spare.

"Testimonies" is the exact word that you would use; that's perfect. Your English is excellent! I completely agree with you about Lockridge compared to Rojas. Beyond the testimony, just her body language and the way she acted like she was in a criminal trial as the defendant cast a lot of doubt as to her testimony, compared to the very matter-of-fact and straightforward Mr Lockridge.
@@toddabowden Thank you very much!😄You put it on point. I am always amazed by the love of professionalism and objectivity that many people, especially engineers, display. That's why I believe Mr. Lockridge. There was real disbelief and anger in his voice about the conditions.
Loved this video. So well editted and put together. Would love to see more about the hearing...and you mentioned making one about what industry experts said?
They knew the hull was compromised since 2022 and still did not stop. And did not tell the „Mission specialists“ anything about that. This was cold blooded murder. There is no waiver that could sign you off of that.
SubSea review can kind of be mistaken if dropped in conversation quickly, as the - SubSafe quality inspection review / process, which is The Navys Nuclear Submarine inspection process, which has helped ensure zero losses due to manufacture since it's implementation. Or perhaps I am being too cynical with that and reading too much into it ? Thank you for making these video's explaining the construction, material properties and timelines. I have watched many, ranging from some very good and some quite poor, being done only for getting those 'trending' views. Some from Divers and some from people involved in the Science's amongst the multitude that are out there. However your explainations throughout have been on a whole other level, and this really stands out when I watch other channels videos on the subject. Thank you.
Great video! A narcissist who listens to his own ego irrationally overrule well trained engineers can be quite dangerous to those who trust their lives in his professed competence. Beware this sort of tourism and it goes for space travel, high altitude mountain climbing, and other risky endeavors, just as well.

Just to let you know. The video titled 'Coast Guard Video: Titan Sub Salvaged Off Ocean Floor' seems to be corrupted at about 12 minutes 30 seconds in.
oceangate would heart their own comment, pin it fine but liking and hearting it is cringe
HEY JEFF how ya enjoying the 100 grand you made off that FAKE "transcript" video from last year?! haha you made a sucker outta each and every one of us!
When even Boeing finds your design too dangerous and refuses to participate in the design manufacturing, that is really bad.
😁
hHAHSHAHAHAHAHHAHAHAHAHAHAHAQHHQHAHQHQHQHQHA
What's that suppose to mean? You mean thousands of Boeing aircraft that fly all over the planet are suddenly no good?
@@borghorsa1902No.. he means that Boeing are infamous, especially since the McDonnell Douglas merger, for prioritising profit above solid engineering. The recent 737 MAX fiasco is all you need to know when it comes to how Boeing operate these days.
So his point was, simply, that it’s painfully ironic AND concerning that Boeing didn’t want anything to do with the Titan sub, given their track record.
Who need Boeing to know that a carbon fiber pressure hull is dumb idea, even school student know that.
Those death waivers the passengers signed won't hold up in court given how much misrepresentation and fraud they engaged in.
@tomr6955 *mission specialists 🤣
Especially when the minimal 'safety measures' put in place were completely ignored.
Nah they weren’t on there they left before the “freak off”
The Titan had made successful dives to the Titanic's depth! Where's your "misrepresention"?!
@Gravitys-NOT-a-force it's like driving on a bald tire just bc it made it down thare don't mean it won't blow the next time
I remember in a business law class learning that gross negligence is very hard to prove, because you have to prove it was done consciously and deliberately, and not just someone being ignorant of a risk.
My teacher's jaw would have hit the floor seeing this absolutely flawless example of gross negligence.
I was telling a friend about all these findings. It's like every step of the way, from the business side to the scientific/math side....there was absolute negligence. And it was driven by Stockton Rush and reinforced by the people who chose to stay. It's mind blowing how bad this is. It will be a business case study for a long time.
It will probably be taught as an example in the future!
This case will definitely be used in studies and references.
@@puzzlechick163 remember there was a 25 page document that highlighted it all that SR sued David over in Court, it's all documented he bullied people into getting his way, money talks with these type of people.
The more I learn about Oceangate and specifically Stockton Rush the more I'm absolutely flabbergasted.....what a absolute shitshow!
Any time there’s lack of oversight, this garbage flourishes. I’m still somewhat gobsmacked that 2 billionaires looked at Rush’s operation and Titan, and gave it their seal of approval. They probably thought “Hey, if P.H. is here, it must be fine.” It’s one of those moments where commenting a lot, or not at all and a SMH, equate to the same result.
..and it utterly fascinates me. As someone who has shopped for carbon-fiber bike parts, I am was surprised by the outcome of this venture. I only wish I knew about it before it happened. Ignored the news cycle at the beginning (drop-release of information annoys me) but am glad that we have even more info in this past week than what we had a few months ago.
People talk about the fact that nothing was certified, but that alone wouldn't have necessarily been a big problem on its own. There is one other deep sea submersible tour company that I know of which doesn't have any certification which has been operating for longer with no significant accidents, and the owner of this company, Karl Stanley, has gone on the record to say that Stockton Rush consulted with him and sought his advice on various things, but ultimately IGNORED most of his advice! All accounts point to Rush frequently ignoring advice from people who were more knowledgeable and more experienced than him.
He's actually been in the Titan sub before, and there is a great long interview with him that you can find here: ua-cam.com/video/n40ukuk9Ay4/v-deo.html&t
Karl Stanley and his company was something of an inspiration to Stockton Rush, but this other uncertified company still has taken far more precautions, and never tried to go anywhere near as deep, or take anywhere near as many risks with a new submersible design, than Stockton Rush did.
"No! My controller! 😡"
Watch Mission Specialist Fred Hagen's testimony on September 20. He, too, was personally very impressed with Stockton Rush. Mr. Hagen insisted that he be allowed to go down in Titan's first dive to the Titanic in spite of earlier awkward "incidents."
I believe a scientist over a passenger. I believe David Lockridge over a "mission specialist". No contest.
That womans ego wont let her admit publicly that she panicked.
Not to mention that even if both were being completely honest, they'd still likely give conflicting testimonies. That's just the nature of human memory, especially for stressful situations, and after so much time. Even two people in the immediate aftermath of an event with nothing to hide will give conflicting testimonies.
Still, David is certainly the more credible testimony of the two.
@tomr6955 David lockridge has no vested intrest in the company nor can he be made liable. Renata Rojas on the other hand was an investor in the company and friends with the CEO and she was on the PP ''helping out'' when the accident happend. I would say Rojas has is pretty biased for those reasons and was obviously less than truthful with her statemens and purposely ignorant, because when u are under oath ignorance is bliss.
@@salland12She’s friends with Stockton’s family too
@@salland12 She was entirely clueless as to why DL kept asking Rush for the controls? "He got us out of there in one swoop ... very skillful" i.e. admitting that Rush screwed up?
My father in law went to high school with Rush (Phillips Exeter Academy in NH), and said that he was always like this. He played on the same sports team with Rush. Said that Rush used to miss practices and demand to be first string. Rush would lose them games by trying to play as if he was the only person on the team that could do anything, all for his personal glory and not a team player. Rush would lose them games and then berate other players that it was their fault. He said that they all assumed that Stockton's parents donated enough to the school to keep him on the team.
Textbook narcissism.
Seems very on brand for this tool.

Q
Ummmm sure
Boeing, who isn’t even in the submersible business, saying “In our opinion you need 10 inches” and Rush saying “Nah, 5.” is probably, for me, the #1 datapoint telling me he was psychotically focused on cost above everything else. Datapoint #2 would be that underbed plastic container he called a “scrubber”. And of course, we now know that he had employees forego pay a couple times to keep the ramshackle operation afloat. He was probably near desperate by the time that last “expedition” left the dock, which is always a great mental space for your pilot to be in as he pushes you under hundreds of atmospheres of pressure with no means of abort or escape.
He did state "at some point, safety becomes a cost". Yeah, so does murdering people for profit.
🙄
Considering the defective production of the vessel, would a hill twice as thick have mattered in the end?
That's what she said.
Boeing said 10 inches for 8600 meters. The titanic is at 3800 meters so they thought 5 inches is enough.
The part that upsets me the most is that Stockton never got to know how wrong he was, or what the consequences of his actions were. If only we could turn back time and show him these images of his crumpled up sub at the bottom of the ocean.
How do we know he never got to know?
I doubt the "red mist" which comes over us as we listen to the ill-conceived Titan idea, build, and OceanGate's unprofessional business practices, etc, would reach Rush's eyes prior to implosion...
We learned and are saddened by Rush's hubris and incompetence, but he died barely milliseconds before the evidence swallowed him up within his mangled "dream machine"
He still wouldn't accept it. Even if he saw those images of the imploded sub, he would find someone else to blame or argue off some stupid technicality. He was too arrogant and egotistical to ever accept his wrong.
He would never believe it. He would find a way to put the blame on anyone else. His ego was too big and too fragile, and he was too greedy, to accept his own failings.
He wouldn't change anything. It's a mistake to think that we can change crazy people with facts. He would just attack whoever did that.
David Lockridge is by far the more believable witness. He showed up without a lawyer, she didn't, the story was basically the same except the pieces that would make Stockton look bad, what Lockridge said was on par for his personality based on several other witnesses, her version of how he handled it wasn't.
Renata was shaking her head yead yes when she said there was no crying or cursing. If she was telling the truth, she wouldn't be shaking her head no
lol, she's so transparent
Watch Mission Specialist Fred Hagen's testimony on September 20. He, too, was personally impressed with Stockton Rush. Mr. Hagen insisted that he be allowed to go down in Titan's very first dive to the Titanic in spite of earlier awkward "incidents." Lockridge obviously has a deep dislike of Stockton Rush.
She's a Rush groupie, in effect.
@@Gravitys-NOT-a-forcehe has a deep dislike because Stockton was masquerading as an expert in the field that DL actually is an expert in. He was hired to ensure a safe operating environment and was fired when he attempted to do that. Stockton was an egotistic narcissist who played Russian roulette with everyone’s lives. Including his own. Whether a wealthy man with zero training or real, deep knowledge of the system he is a passenger in was “impressed” by Stockton or not is important. Fred got lucky. That’s it.
No doubt lockridge has it right... Her testimony as a current family friend is WORTHLESS
Narcissists employ their fans or friends to do the dirty work for them, her testimony came off as too defensive, she was more hurt over the fact that Lockridge said she had tears in the eyes and was scared than that Stockton killed all those people. Never trust unbiased sources. Let's hear the testimony of the other members of that exact dive.
Yeah, plus, if there wasn't an actual situation, then why was she so impressed with his abilities?
The inquiry looks very formal, so she was probably under oath, and assumed a lot of perjury risk by weaving a false narrative.
Did they have any other passengers onboard to ask the same question to?
Memory isn't flawless. but David looks like the type of guy to literally write the events into a notebook as a precaution for investigation.
She instead looks like she may have recoloured her experience and memories with her subsequent interactions. It's possible Stockton didn't throw the controller and it was a subsequent nightmare or something that changed the given testimony. But the key facts? Such as the refusal to hand over the controller? Probably valid.
6:45 when you get a rejection letter from Harvard and tell everyone “I’ve been in communication with Harvard”
Or you get a rejection letter from Harvard and tell everyone "Harvard considered me but I decided to go another way"
Or when you shake hands with someone who once worked at Boeing and saying you're in partnership with Boeing.
I was in communication with the admissions department of MIT twice. I visited the campus but never attended or graduated. I did go to Harvard, though. In one end of Harvard Yard on out the other.
David Lochridge's entire testimony was fascinating. To me it seems like he truly did everything within his power to prevent this from happening. I wonder if anything will happen to OSHA after his testimony.
nothing will happen, maybe some ammendments to some obscure rules and procedures, but OSHA will just walk away with a slap on the wrist, that said the documentaries will probably paint them in a bad light.
He was warned that the vessel was not safe and didn't follow safe engineering regulations. He just ignored many highly skilled engineers warnings.
Damn if Stockton almost killed me and then threw a controller at my head I'd have a hard time not giving him a tune up once we get to fresh air.
Ms Rojas's testimony came off as defensive, she seemed more hurt by the fact that Lockridge said she was emotional and fearful with tears in her eyes than the fact that Stockton killed 4 other people and himself in the last dive. The fact that she's a close friend to the family makes her testimony questionable, she also omitted the part where Lockridge was hit in the head and only picked the parts that would not implicate Stockton so much, such as Lockrdige asking for controls, taking over the control and maneuvering out of the bad situation - these are all true, however, that is selective testimony which contradicts Lockridge's account. So, one of them is lying about exactly what happened, and anyone with more than two brain cells can see who.
She might of had Explosive Anger, blasting Rush to hand the controller to the other guy. ( Those Extreme Anger Episodes can be Compartmentalized from the personality shown in public). Very common..

@@Gravitys-NOT-a-force why do you keep spamming this
@@peabody3000 , maybe if Stockton had not DIED on that last dive, I'd be quiet. He believed in the Titan, the engineering that went into it. Listen to Fred Hagen's testimony on September 20.
@@peabody3000 , you think this is a dedicated 'Trash Stockton Rush' site? The Titan HAD made 13 successful dives to the depth of the Titanic. Each Bell Boeing V22 Osprey aircraft costs $84M - and they still crash because of engineering design failures.
Safety was never Stockton's M.:O. and he cut corners everywhere he possibly could. So, my hunch is that Stockton set the guidelines to 8600 metres deep ( , not so that he could have a high margin of safety. Rather, so that he would have a high margin of corner cutting.
This is how I think he eventually arrived at the 5" thickness specification. Stockton figured that if they recommended 10 inches for 8600 metres, then half the thickness should work for half the depth. Which in his case would be the Titanic Depth. An idea like that is something Stockton would have come up with.
Excellent point.
I majored in English, so engineering is far from my area of expertise. However, I don't think decisions like this seem sound. I imagine pressure might increase exponentially or carbon fiber require a minimum thickness, etc.
I heard the hull was eventually made in the 3.5in range.
Woven Carbon fiber cloth, epoxy resin... they share a solid state overlap but it doesn't have molecular granularity like a metal alloy's crystal lattice. I think epoxy is an amorphous solid, a polymer. And Carbon is a crystalline solid. Those two kinds of solid diverge in their property and behaviour. This obviously implies the integrity of their composite strength diverges as the two go their seperate behaviour ways along unequal material properties paths at seperate solid state intervals making the laminar yield strength a bit of a mirage and more or less disposable after use.
@@santyclause8034 it definitely had a limited number of dives and it was Rush's job to figure that out. He either failed or didn't care relying on the RTM system. He was listening for separate strands to quietly break when in reality they were getting gum blasts from the first dive.
If what Lockridge said isn't true, then why was she so impressed by his ability to maneuver out of a situation? If there was no situation what would there be to be impressed about?
Family friend.
Also, David was standing by the window so "he could actually see all the way around." Okay, so why wasn't Stockton doing that??
She sounds defensive, typically defensive
I hope she's found guilty of perjury soon, as she's lied and put David down all for Oceangate because she's besties with the Rush family, I honestly hope their all held accountable as they all knew about David refusing to go in the Sub and asked him to redact his list of faults and concerns etc, it's just absolutely disgusting how they all choose to ignore it and kill all those poor passengers, it's like SR had a death wish!!,
What Davids said is all true, I know that for a fact.
I believe David Lockridge all the way. I saw a different ‘mission specialist’ whose account matched Lockridge’s account.
Enjoy your work in sharing details. Awesome, work, Jeff
Thank you very much!
Second that!
Thanks for all your analysis of this incident Jeff. So appreciate your work
I'm glad you found the analysis helpful! It's always a pleasure to share insights on these incidents.
We’re REALLY seeing a problem of people who decide they want to be famous geniuses and then decide how to do it. True geniuses are just interested in the subject and do most of the work themselves. The fake ones dream up impossible ideas and hire others to do the work, but the best they do is incremental improvements not the major breakthroughs promised. Ideas are the easy part. Making them work is the hard part.
Elizabeth Holmes wasn’t a scientist. Elon Musk isn’t a rocket, car, or tunnel engineer. Stockton Rush couldn’t design subs. They just wanted the credit for other people’s work yet their only skill is talking rich people into giving them money.
I did some back-of-the-napkin math based on the table at 12:10 in the video.
A 9.3 in thick hull gets you to a max depth of 8600 m @ 12562 psi. Assuming a linear scale, that comes out to 1350 psi/in of hull.
At 3800m, the psi is 5389. This means that with a 5 in hull at 1350 psi/in, the Titan sub had a max psi of 6754, or 4700m. This is a safety margin of 1.25. Meaning the subs max rated depth was just 25% more than its operating depth.
This is a crazy low safety margin, as others have highlighted.
I'm so utterly curious what Stockton's planned lifespan of the hull was. Recorded dialoge lines kinda show that that's what he was trying to figure out, but when he got extreme and unexpected readings from his own vessel monitoring system, he was so weirdly confident in his sub he just dismissed it. It's almost as if he was just expecting it to leak a little bit, never actually implode. But there's no shot he was that stupid...it boggles the mind
Edit: I forgot money is a thing and apparently oceangate was basically destitute so...I guess that'll do it?
@@skeezixmccatI’m convinced Stockton KNEW when those readings came through that Oceangate was doomed financially. And maybe he had some life insurance or something that he wanted to ensure someone got, so he ended himself in a way that would ensure the money was paid out. That’s just my theory though.
@@virtualgambit577 that makes it extra dark, that he would allow others to meet the same fate. Especially poor Mr Dawood jr
Aye there's the rub, the relationship between depth and pressure is not linear. It varies with the temperature of the water column and not in a good way.
Your assumption of a linear scale is actually too conservative. Besides pure compression, the tube also experiences horizontal bending. A reduction in hull thickness increases bending stresses by the square of the thickness and deflection by the cube of the thickness. Therefore, halving the original thickness increases bending stress by a factor of 4 and deflection by a factor of 8. In reality, the actual stresses increase somewhere between linearity and the square of the value. To accurately model the shell, you need a finite element program.
The mode of failure is primarily due to the difference in stiffness, not just the material properties at the transition ring boundary. Titanium is not only materially stiffer than delaminating carbon fiber, but the half-spherical shape is also much stiffer than a tube. Consequently, it deflects less under compressive loads. This difference in deflection caused the ring to shear off under cyclic loads.
Still can't believe they would just grind down the carbon fiber if there were bumps and add another layer over it... You just broke and removed layers of that fiber, making it weakened there
The bumps were already a weak spot. The bumps are slacked fiber, which would never go in to compression or tension at the same time as the surrounding fibers; meaning those surrounding fibers experience excess load the slacked fibers should be carrying. And that's the problem with flat-braid fiber on a radial form. It's never going to lay flat. Half the fibers will be in an interior bend and half will be in exterior. Any kid who ever covered a ballon with papier-mache has seen this. That's why you don't use it in an application like this, you use a cast material. Grinding the bumps down didnt make it any weaker than it already was, it simply truncated an existing weakpoint layer to layer.
The design was a weakspot. They took a tension-reactive material and square-peg round-holed in hopes it would alchemically convert to a compression reactive material because Stockton's ego demanded it. It wasn't even for cost. They spent so much building and testing his hairbrained idea, and having to build another cause it wore out so fast from cyclic fatigue that had they just made the god damn thing out of titanium in the first place, they wouldn't have had to test as much, would have had a better idea of reliability, wouldn't have had to scrub multiple 'excursions', and externalities would have been more content to sponser or associate. The company would have likely not been so strapped for funds, that there probably would have been enough money to pay employees and also upgrade the plastic tote based life-support systems.
It was all an experiment for Rush. So twenty years from now he could claim 'i was the guy who said carbon fiber had a place in commercial submersibles". And that killed his company, killed his clients, and killed him.
@maxdecphoenix So take Stockton's name in vain or even Darwin's (for his stupidity). No reason to take God's name in vain and use it as a cuss word for man's ignorant and prideful decisions.
All that was missing in all of this disregard for safety was excessive amounts of duct tape being wound over the glued titanium rings and claiming that it's highly reinforced.
He used the word in lower case, surprised you didn’t notice
@@rabbitramen I seen a video before of that tape (Or it looked like it) Being used on the front (I think it was) Taping the Titan's landing :v

It’s unfortunate that Stockton passed away. I would have loved to see him trying to defend himself out of all of this…
This negligence is insane!
imagine all the blame he would be doling out onto others...
Jeff, another outstanding video. I'm a fan of your no-nonsense style and I've learned so much watching your channel. Thank you.

Stockton is a narcissist: narcs get worse with time, their delusions about their grandeur and abilities increase, lies about their achievements and intensity of the advertisement of their imaginary achievements increase, their temper worsens when they face criticism, their attacks on their critics increase, the control on everything intensifies, name-dropping and lies about connections intensify.
*was
And then, every so often, they get what's coming to them.
for sure. given enough time and resources, a narcissist will always use up everything they can and burn it down.
I think I know why the bed liner was used on the exterior. It hid all the imperfections in the hull visible when looking it over as I am sure all the people who traveled in it and viewed it out of the water. This led to a false sense of safety and security... What a shame and waste of human life.
There is an old saying...
"Manners maketh the man" ...in this case (or so it seems to me - and _I'm absolutely_ _no expert_ in _any of this_ )
" _Money_ maketh the mad, sad, and _dead_ adventurer" ...both Rush's money problems - the lack thereof etc - and the multimillionaires / billionaires (whichever) "having more money than sense", being duped into _believing Rush_ over the safety of Titan, and the fascination and draw of Titanic, who can be seen in _great detail_ on video since her specs have been so expertly scanned and reproduced digitally for _Everybody_ to see as they view her on their handheld devices, with absolutely _no need_ to dive to such crushing depths to see her in all of her "rusting glory".
"Safety is a waste", is it Stockton...?
I wonder what Wendy and the rest of your family think of that idiotic boast now?!
Well, it did protect from external damage. Have you ever had anything that is made of fiberglass or carbon fiber? Let's say you're moving something and it happens to hit the submersible. Now you have a scratch, ding, or worse that can affect the integrity of the structure. It's not unlike how it protects the bed of a truck.
I think the "bed liner" made engineering sense, but Stockton should have had some way of scanning the hull after each mission, perhaps some acoustic-based machine - ultrasound ? - to detect cracks or anomalies. Not performing such a test was irresponsible/insane.
@@entropywizard someone like stockton would have rationalized the data away every time, no matter what, no matter how damning. and the bed liner sounds reasonable but it was never tested for this use. and if it isn't tested, it's merits are unknown, simple as that. overall it's a great illustration as to why narcissists should never be trusted.
@@entropywizard , it seems that Stockton had no scientific way of checking the integrity of the wrapped composite-fiber hull. That was serious negligence. But the Titan had made 13 successful dives to the depth of the Titanic. Stockton, evidently, had made a serious effort to interpret the cracking sounds made by the wrapped hull. Obviously, his interpretation of those cracking sounds was faulty.
That submersible was never beautiful. It was dangerous childsplay by a wealthy ego wanting a bigger reputation . Stockton Rush should have been the only one allowed to play his fantasy games in it and the only one to succumb to it's ultimate death sentance. And... getting locked inside the ugly beast with no way out from within is a ghastly suspension of good judgement. The whole thing was a sham.
And YES more of your great analysis and breakdown of the proceedings!
Lol "Beautiful"
I have never gotten over the fact that they used old pipes as drop weights. And the fiberglass viewport. And that people sat on the floor. It was like something someone built with legos and then called it "beautiful"
What is sad is he found people gullible enough to not only get IN the darned thing but think it was going to take them down to the titanic and PAID for their death. How can someone be THAT rich and be THAT dumb ???
@@Aamria I guess they were too obsessed with seeing the Titanic rather than putting thier Safety first XDD
Let's be fair here. It was not a PlayStation controller.
It was a generic, knock-off playstation style controller.
A Dollar General knock-off!
👌🏻
They had a PlayStation controller in some of the development videos (like Texas University), seems like they changed it at some point.
Sure it was a crappy little Logitech controller, but it was also the only thing on the Titan that was engineered well, when you think about it
@JustJesstheMess I thought it was a madcatz but no you're right it's even worse it's a Logitech 🤣 because who hasn't had a Bluetooth device totally disconnect and refuse to reconnect for God knows how long 🤣🤣🤣🤣
This reminds me of the “Tragedy beneath Boston Harbor
In 1999, two divers died deep in a 10-mile-long Deer Island sewer tunnel. a “hotshot engineer” whom the contractors had hired came up with a plan to mix liquid oxygen and liquid nitrogen and turn the mixture into breathable air. “The disaster was described in the 2014 book Trapped Under the Sea by Neil Swidey. The book tells the story of the divers and the events that led to their deaths, including the removal of the ventilation system and the use of a makeshift breathing system.”

Wish I had the time and patience for those USCG livestreams, but I knew Jeff would do a tidy analysis with choice clips at some point. Thanks for coming through again, friend.
You’ve got that “late night radio host” voice. It sounds great
I really appreciate you posting concise videos and actually going through these hearings to clip the important parts. I discovered your channel after the Surfside collapse and really dig the hands on, highly detailed work you do. Thanks.
Thanks Jeff, love the vids!
Glad you like them!
Engineers may be annoying but they exist for a reason!
Ms. Rojas has a complicated relationship with honesty.

@@Gravitys-NOT-a-force Yeah, you keep spamming this same comment all over the place like this guy's opinion matters. He was a "mission specialist" aka a paying customer, not a mechanical engineer who specialized in hydrodynamics. Stockton Crush was nothing but a low rent con man with severe narcissistic personality disorder, who, had he made sound engineering decisions, would not be the subject of all of these comment threads today.
@@flapjack413 , when's the last time YOU designed a vessel capable of taking five passengers down to the Titanic (0 deg. F and 2.7 tons/in^2 pressure) and then bringing them back, safely, to the surface? Last week, right? Stockton Rush's Titan submersible did that 13 times.
Has someone noticed this @ 10:47 . They calculated with 2 cures per inch. Ocean Gate did only 1.
Well spotted 👍
Jeff- your coverage of the titan disaster is second to none- Thanks!!
I’m new to your channel, and I’m enjoying your videos very much - Incredibly informative. You asked if we want to see a compilation video where you highlight all the pertinent testimony - absolutely! While I certainly appreciate all the documentation you provide, it’s the human testimony that’s the most compelling to watch…
Great work Jeff as always 👏🏻😍
Greetings, Jeff. Thank you for another excellent video. Yes, I would like to see as many videos as you can produce on the topic. However, no matter the topic, your videos are always clearly stated and informative. You never talk down to us nonengineers. Keep well.
I believe the experts. The mission specialists all seemed to be true believers. They were, the ones I've heard, very careful and elaborate in avoiding blaming SR.
This is GREAT information. Love the receipts and backup you show. It really helps!! Thank you!
It will always amaze me that Rush was able to take customers down with him. In a sub labelled as experimental and uncertified.
Mission specialists 👍

Was definitely looking forward to the next installment 💗🤭😊
Hope you enjoyed it!
This is one of those stories that might get told in engineering school. The most important thing a young engineer should take from this is try not to make yourself compromised if you were to need to walk from your company. I have walked and it is extremely expensive to either resist until fired or resist and get bullied out. I lost about $200,000 a few years ago walking from something I was morally against. Buy half the house you can afford, buy good used cars and take good care of them, limit child count and learn about narcissism and avoid company heads that are that way. They will kill you to keep from being embarrassed.
Well, he did get his interior lights from Camping World, so you know that he overpaid for all the other parts too. This design would make Wile E. Coyote blush.
"You know, at some point, safety is just pure waste."
Hey, now. Wile E. was a super genius and always got his stuff from the amazing Acme Corporation. There was nothing sketchy about his designs. It was just that the Roadrunner maxed out his luck attribute and no amount of design could overcome that.
Unfortunately (& especially for Justice for his _four_passengers_ )
Rush (& the others) _became_ that self-same "waste" during the implosion.
Thank you for your excellent work, Jeff. Best coverage of this tragedy I have found. I also love it when you tone down your voice when presenting these testimonials. Makes the whole thing like witnessing an Alfred Hitchkock thriller.
Oh yes, Jeff. I'd love to learn more about the history and what happened.
There is a lot of information and testimony from the engineers that reviewed the titan before it went down.
Yes, please continue to create more videos
in a concise format,
featuring expert insights and testimony
from industry professionals.
Thank you also for explaining what happened;
it is really appreciated.
I wouldn’t have sat on top of the water in this experimental submersible. Stockton was 100% crazy
I'd love you to do more videos on this. This was so informative and interesting. I'd love to see more
Keep the vids comin'. Your opinion and things you point out tend to be your own. Other videos I watch are all the same things we already know and no educated opinion so please, if you have more, give it to us.
Please do more of these videos we cant get enough of your titan videos this was so informative!!
Lockridge is describing a totally unprofessional work environment...
I wonder if anyone else was on that dive along with the 3 of them. It would be interesting to hear their account being as David and Renata's accounts differ significantly.
To be honest the unprofessional environment is spot on because multiple employees quit or got fired all had bad things to say so yeah I believe him
There was that other young employee who's accounts were very similar. Anytime she questioned why things were done the way they were, it was all handwaved, and she was told by her supervisor/manager that she shouldn't be questioning things and that her behaviour didn't "align with the company" because she wouldn't just be a yes-man. Sounded like a very toxic work environment all around, top side and all.
@@foskco87 There was another man on that dive, but IIRC from Renata's testimony, he has since passed away.
Yes, I would like to hear more testimony and explanations.
Thanks for the education!
"Stockton Syndrome"...Oceangate was like a cult and those who got out before the koolaid got passed around are lucky. My favorite joke so far 😂
I'm totally interested in you doing more of these videos with the other experts. Yes, keep doing these 👍
What a shame that Stockton's arrogant stupidity got other people killed besides himself. I get really sad when I think of that young kid that died as he did not have enough life experiences to know he was in mortal danger.
Really first rate presentation of a difficult subject - thanks for spending all your time looking for the information and comments we all need to hear!
Another uber interesting report!!! Amazing what details are coming to life. I think I’m turning into an engineering nerd 🤓!!
Very useful and clear summary of some of the testimony. Tastes like more... 🙂.
There are a few key players not being questioned. One is Wendy Rush, she was responsible for for the social media hype, and she was on the Polar Prince on the fateful day. Board members are not being questioned. Why not? Its very suspicious.
Maybe because they will be defendants in upcoming court cases, they don’t want to implicate themselves at this hearing. Their lawyers also might have advised them not to.
She is exactly like her husband. They scammed together. Imagine choosing that man over literally anyone. Her money is buying her convenient absence.
Because they are being sued.
Its amazing how many submarine experts come out of youtube hiding that have never took risks or done anything with their lives
That’s for the great detail Jeff!
When your top engineers are fired from not signing off, something is very wrong.
One detail you missed on the original spec sheet was cures per inch on the hull. The original plan was 2 per inch instead of the 1 per inch that they ended up with, they definitely would’ve got some reduction in voids with the extra cures. But autoclave time was just too expensive for rush.
Seeing all these details and considering how many dives the titan lasted almost makes me think that a well engineered and thoroughly tested carbon fibre hull could’ve worked really well and rush could’ve been seen as the innovator that he thought he was
Agreed. The fact this thing was able to dive on the Titanic so many times given the soddy quality of the lamination and glue joints really speaks to the resilience of the material.
The hull monitoring system did a good job as well. It clearly showed a major shift in hull layers on the prior dive. At that point it should have been decommissioned.
Composite materials, woven carbon ply amorphous solids and aggregate cementing bonds, does not destruct in nearly as predictable a failure as crystalline solid matrix. Doesn't have overlapping state equilibria like metal alloys (alloy lattice structure solidifies/quenches within a given thermal phase equilibrium window of overlapping state). Failure under loads like the Abyssal Deep is clearly going to escalate non-crystalline composite laminate to yield point strength failure in catastrophic fashion. Which is a long way from alarming and scary signs of danger with safety margins of moments to spare.
"Casual observer" hehe... very good video again Jeff, keep up the good work..always good too see new and interesting content...got only one question how was the outside equipment connected to the pressure vessel?! cheers from Croatia.
Walmart parts bin suisub built on the cheap. He sure didn't care about cutting corners or safety. He bamboozled everyone who paid him for their "adventure."
My question is how did he get usually fastidious billionaires to sign off on being experimental lab mice (paying 250k a pop for the privilege) to go on a rickety garage-DIY sub supposed to withstand 6000 PSI?
@@scroopynooperz9051 He put on a dog and pony show full of smoke and mirrors. He thru names around like NASA, Boeing, University of Washington APL, claimed they were all his partners who sighed off on his monstrosity; he would never lie, would he?
"Suisub," I like that.
@@williamprice3929 yeah but when it comes to spending their money, billionaires usually sniff out BS like truffle pigs - they didnt become billionaires by being easy marks.
Edit: I can only assume that what confused them was Stockton's pedigree. He came from the right background, schools and had the links.
@@scroopynooperz9051"Ahhhhhh, your going to go visit the Titanic, how many people on earth get to do that? You'll be the beau of the Riveria, all the talk of the cocktail parties. Look at all your bragging rites?" What just as important as money to these people? Prestige. How prestigious are you, you went and visited the Titanic? That's a lot of prestige to these folks.
Love these vlogs, so much to take in. Watched this 5 times, might have to see again. Much much more please, has to be in depth as this is complex.
im interested in the additional footage and content that you mentioned!
Gotta respect an engineer when they tell you the truth, especially when it's their job on the line
Button falling off of the Logitech controller after a strike to the head is consistent with the reported durability of those controllers.
It shows how uneducated people are when they try to joke about the controller when that was the most heavily engineered object on that thing that has been used for over 20 years all over the world by all military in all conditions without a single f****** problem😅😅
great vid, would love to see the tidbits, thank you!!
David was the professional who piloted the craft away from the wreck.... Renata was Stockton's friend, so
Great reporting. Thank you.
"Military grade" is a team used to make things sound good, but really are the worst. Remember, military grade items are made by the lowest possible bidders.
This statement is categorically untrue. Military grade is often used as a marketing tool by certain manufacturers. Military grade in its true meaning means it meets a certain MIL-STD (Military Standard) and is tested to meet that standard regardless of price. Tested by actual engineers and by a third party.
Thank you for the laminate flooring stuff. The flooring tiles were replaced with laminate flooring, however no insulation. It is always so cold. The heater keeps my upper body warm, but my legs are always cold.🥶
I´m also listening to the hearings and since english is not my mother tongue I sometimes have difficulties to understand everything. But I noticed the difference between Mr. Lockridge and Renata Rohas "Testimonies" (i don´t know another english word for it). And I think you have a point. Mr. Lockridge seems to me to be too professional to think of something like that.
"Testimonies" is the exact word that you would use; that's perfect. Your English is excellent!
I completely agree with you about Lockridge compared to Rojas. Beyond the testimony, just her body language and the way she acted like she was in a criminal trial as the defendant cast a lot of doubt as to her testimony, compared to the very matter-of-fact and straightforward Mr Lockridge.
@@toddabowden Thank you very much!😄You put it on point. I am always amazed by the love of professionalism and objectivity that many people, especially engineers, display. That's why I believe Mr. Lockridge. There was real disbelief and anger in his voice about the conditions.
Absolutely! Id love to see a compilation of the testimony
I THINK HE REDUCED THE THINKNESS BECAUSE HE WASNT GOING DOWN TO 8800 HE WAS GOING TO 4000 TO THE SHIP SO HE THOUGHT HE COULD NOT MAKE IT AS THICK.
Yea he didn't calculate..His math wasn't mathing 😂
Loved this video. So well editted and put together. Would love to see more about the hearing...and you mentioned making one about what industry experts said?
They knew the hull was compromised since 2022 and still did not stop. And did not tell the „Mission specialists“ anything about that.
This was cold blooded murder. There is no waiver that could sign you off of that.
Please keep the excellent videos coming!
May all those on Titan submersible that lost their lives in 2023 rest in eternal peace 😢 regards from Melbourne Australia 😮😢
Dude this is great stuff. Please keep uploading this content, it's riveting viewing.
SubSea review can kind of be mistaken if dropped in conversation quickly, as the - SubSafe quality inspection review / process, which is The Navys Nuclear Submarine inspection process, which has helped ensure zero losses due to manufacture since it's implementation. Or perhaps I am being too cynical with that and reading too much into it ?
Thank you for making these video's explaining the construction, material properties and timelines. I have watched many, ranging from some very good and some quite poor, being done only for getting those 'trending' views. Some from Divers and some from people involved in the Science's amongst the multitude that are out there. However your explainations throughout have been on a whole other level, and this really stands out when I watch other channels videos on the subject. Thank you.
Great summery video!
Great video! A narcissist who listens to his own ego irrationally overrule well trained engineers can be quite dangerous to those who trust their lives in his professed competence. Beware this sort of tourism and it goes for space travel, high altitude mountain climbing, and other risky endeavors, just as well.
Yes more info videos would be greatly appreciated. Thank you for your work. All your videos are very interesting and informative.
Good summary of CEO hubris and risks to public safety.
Great content and compilation of testimonies.
I just have to say, sir, there's a mic boom in your shot.
😂
