The more I hear about this the more convinced I am that Stockton Rush was a grandiose narcissist of the highest order. Not only did he think himself above the laws of man, he thought he was above the laws of nature. Physics doesn't care who you are or how great you imagine yourself. Its laws are immutable and apply to all equally. You flaut them at your own peril.
That's why pride is a deadly sin.
Greatly stated.
2,bonk22 well put and so to the point👍💪😉
Yes and what have you achieved
probably was close to bankruptcy too or wanted a spike of money by JUST accomplishing something big and getting big people invested
Let’s face it. The materials and methods used on this sub were always going to fail. I can’t believe it was able to work as much as it did.
Absolutely.
Agreed. Carbon fibre can't withstand compression. Acrylic is just acrylic.
I read that the Titan only visited the Titanic three times
@henrikson2902 on another channel analyzed how many trips Titan scheduled to how many were actually completed, and the success rate was like 14%
@@staciasmith5162 14% was properly high. no doubt ocean gate was counting a number of failures as success
Wow, I just can't get over the nature of the amateurish hobby shop nature of this whole project. Just goes to show that a bully with money is one of the most dangerous types of person out there. Good work Jeff on exposing this.
No a psychopath born with money is the most dangerous
@@Chad-Giga. Did you read what I said?
@@mariemccann5895 Tbf you said a bully with money. The other guy said born with money. There is a difference :)
@@theinsanewoodsman Read what I said.
While there's some truth to that - there's also more than a little bit of Monday morning quarterbacking going on. The egregious part here is that you didn't have a wide range of engineering buy in to the design - while the implications of failure are obviously dire.
I don't think since _Challenger_ there has been such a clearly identifiable set of failures leading to a tragedy. Truly one for the books.
That's true, the engineers knew it was unsafe, but the person in charge was pressured to signing a thing saying it was ready.
There was definitely a sense of "it worked every time before so should be fine this time", and I imagine the same occured with the sub.
What are you talking about? James Cameron’s Deepsea Challenger made it to the most bottom of the ocean the Challenger Deep hence where the name of his submersible came from. And there was no tragedy he’s been to the bottom of the ocean 30+ times now
@@AcidAroma The space shuttle
It took a couple years for us to get to the bottom of the Challenger accident, even with knowing the proximate cause near immediately. The same is going to be true here. Just because people are waving their hands at the Carbon Fiber hull - for probably good reasons - the precise details of the failure, the manufacturing and/or design defects that contributed, etc., etc. That's going to take time to know.
Yeah and also just like challenger, people lost their lives because in part due to it was cheaper. With challenger, I’m aware the o ring failure was multiple factors, but a huge reason being bc the weather wasn’t ideal launch conditions and knowing this (and that they could have rescheduled it for another day), they ended up doing it anyway. With the Titan, I’m 1,000% convinced it’s Stockton Rush who is at fault. HE acted like he was a pioneer/engineer/innovator, despite the fact that (IMHO) he was NOT any of those things. He chose to use this stupid carbon hull. He made the choice to implement so-called ‘safety systems’ which could not/did not work as a fail safe to get the occupants out of danger. He made the decision to tell real engineers/experts & fellow members of the private submersible community to reject safety concerns, deny any sort of actual scientific evidence and keep diving anyway. Let’s be honest, the only person who could have convinced Rush to rethink the whole design for the Sub, was Stockton Rush. Just goes to show us, the innovation sometimes breeds unfortunate martyrs of industry, but these poor people and (frankly) IDIOT Stockton Rush were martyrs for the wrong reasons. Conclusion that doesn’t sit well with me is what not many ppl talk about much: capitalism has many pitfalls and repercussions to our society. Greed, lust, notoriety and fiduciary responsibility are a dangerous cocktail and will inevitably always result in corner-cutting, rushing, lack of oversight, etc. and then we see sh*+ like this go down and it’s just a constant reminder to those still unconvinced, “hey my dudes, capitalism be like ruining the planet, corrupts people and literally is NOT sustainable for much longer unless the capitalists are actually trying to make Armageddon happen. RIP, you stupid dummy (Rush) and to those affected by losing loved ones just along for the ride, ❤ take care y’all.
My belief is the acrylic window was blown 'outwardly' due to effectively an atom bomb explosion after the implosion. When the carbon fiber hull failed, with the weight of the ocean on the vessel 400 bar of incompressible water versus 1 bar of compressible air atmosphere, an exothermic explosion resulted and of course the acrylic window with conical shape shot out the vessel like a wine cork.
Lastly, there are no words for how sick Stockton Rush was. A maniac aka wolf in sheeps clothing.
Jeff, your videos have been outstanding.
What Im trying to figure out is where are the bolts/holes that held the window on? the footage of it on the crane doesnt look to have any marking of bolts, or where bolts used to be. Maybe that front hull is inside out?
The exothermic decompression was propagated by a reverse osmosis central evacuation infusion with prejudice
I think it was the other way around, the port window failed and the compression blew the hull out creating the debris field.
@@sheilanorris7846 That is completely contrary to the current theories, which are deemed fairly accurate. Your theory proposes the CF succumbed to internal pressure, while it actually succumbed to external pressure - which is also in line with tests done years ago on carbon composite. It fails spetacularly after x number of cycles of compression. This was all known well before Rush started building his deep sea coffin, In fact the design was not even his own, is was from the early 1990s (I am guessing it was Richard Branson's design for a deep sea sub, and stopped the development after James Cameron warned Branson that the thing was an accident waiting to happen). So there you have it, it gets even worse about the total ignorance Rush had for things that did not fit his mind.
How would there be an exothermic explosion? Heat would certainly be generated, but that would be only due to rapid compression of gassed and materials. There would then be a following rebound series but that reaction wouldn't have any opportunity to "explode" an object that would have imploded in less than a millisecond. What are you basing your conclusion on?
I am a maintenance technician by trade. 28 years of experience. I have worked with the vacuum and pressure vessels as they relate to bonding and removing impurities with acrylic mediums. I have never worked with carbon fiber. I am astonished with the lack of safety and materials testing!!! It’s amazing the Titan even worked (kind of) let alone carried passengers!!!
Means the world isnt as dangerous as ppl make it out to be
When your life is on the line, the world is unforgiving.
I’ve worked with carbon fibers in the wind turbine business, doing NDT Ultrasound testing, and its main purpose was to detect voids and cracks in the lamination. It migh’t have been usefull on the Titan sub.
maintenance technician vs Engineer yea not even in the same ballpark
Carbon fiber is great in tension compression not so much and you're relying on the compression strength of the epoxy resins involved and most don't do well like that
One possibility regarding the porthole window I haven't heard is that it may have recoiled like a (40-kg) spring. On previous dives the outside pressure pushed it 2 cm deeper into the cabin when it reached Titanic depth. If that pressure were quickly equalized, in a matter of milliseconds, all that released tension might force the porthole out again, rather than it being pushed out by the force of the implosion.
That's an excellent thought! I could see that the recoil energy (plus implosion shockwave) would be able to shear the bolts right off.
The 45-minute interview of Karl Stanley regarding his experience with Stockton Rush, OceanGate, and Titan as well as his own life diving submersibles (10,000 hours of time underwater) is well worth every second of time doing so.
He Tried To Warn ...
The polished acrylic window may be nearly invisible on the sea floor. Transparent materials lose that chrome-like sheen when both sides of the prism are submerged in water. Jeff, thank you once again for the hard work and great production quality.
Friend lost a pair of “frameless” glasses in less than 3 feet of water. Probably still in the Gulf of Mexico to this day. The darkness down there, you’d have to be extraordinarily lucky to find that 88 lb acrylic window if it popped cleanly.
Should always have been one time use ONLY. Even then...
Not to mention it might have embedded itself into the seabed... I don't know what the consistency is around the titanic but if it's only a little muddy -- that thing, being as dense as it is, will bury itself deep enough to never be found again, be it in one piece or shattered.
That is if you look for it with your eyes ^^
It’s pitch black down there . Over 2 miles deep , that window is years from being discovered
The more I hear about this tragedy, the more I find myself in disbelief that this submersible lasted as long as it did. The dragging it across the ocean on its own little platform? That's shocking.
It would be interesting to know what kind of sea states that platform experienced, and what kind of forces the pressure hull experienced as a result via the chassis/frame attachments. I think we can assume it wasn't designed per se to be rugged in this application.
Was it dragged on its own platform only that one time?
I've done about a dozen dives down to the Titanic. It might be about time to move the wreck to more shallow water to avoid more deaths. Amazing that over a hundred years later the ship has claimed more lives.
@@beckydoesit9331How would they move it exactly?
@@beckydoesit9331sure you have buddy...I just finished my seventh moon landing and am currently trying to get someone to move it closer to earth. I hate having to go 2 weeks without fresh seafood
This whole disastrous tragedy is beyond, sad. It's heartbreaking. I daresay if the much loved, expertly knowledgeable and much revered Jacques yves Cousteau were still alive, even HE would have known better than to get into something like that. SAFETY, was always paramount in ALL his dives.
9:18. Comparing the Titan's two hemispheres with those of the Limiting Factor submersible, I noticed that they depart significantly from true hemispheres. There is a conic frustum feature clearly visible in the video. Also, looking at the surface condition of the metal, it appears no surface machining took place, so these hemispheres could be very imprecise. According to the documentary of the design/build of Limiting Factor, the hemispheres had to be within much less than a millimeter of true hemispheres in order to maintain a balanced inward directed pressure on the hemispheres (and no forces in other directions). The other thing I wonder about is the carbon fiber reinforcement lay direction(s). All I've ever seen in video is a circumferential 'winding' lay direction. The cylindrical section would have the same anisotropic strength properties as a slinky whose coils are lightly bonded with plastic cement.
I'm a motorcycle mechanic and thought the same thing.
Even with the common 'half lap' (which I didn't see in video clip) it isn't a homogeneous structure. Near where I used to live there was a company making BIG fibre-glass round storage tanks, (15-20 foot diameter) they developed a process for winding diagonally but with varying angles (IIRC?) which made tanks much stronger (25 years ago they were shipping them all over the world as no one else had figured it out)
For a cylinder under axial and radial compression, there is NO direction of layment that puts forces where CF rope is at it's best which is under pure tension. The resin did most the heavy lifting and that's what was making the cracking sounds. Steel (for the cylinder) would of been the ideal material to use as there is multitude of NDT methods available to check it's integrity before the next submersion. It's also monolithic and strong in EVERY direction. Ditto for Titanium if weight is a critical factor (@ a lil over half the density of any Steel grade). Strength to weight ratios favour Titanium but it's a hell of a lot closer then you think when using the stronger Steel alloys. This guy gambled .. and lost, taking a few with him
I saw in another video where the layup was a "0 - 90" one, with the horizonal bands being laid up by hand and not shown on any of OceanGate's manufacturing videos.
@@xenuno They definitely would have used titanium over steel, it's a sub, weight 100% is a factor, because you have to counteract that weight to get your sub to float back to the surface.
@@shawnpitman876 True but .. the strongest alloys of steel are quite a bit stronger than the strongest titanium alloys. Without doing external pressure calculations, possibly the Steel shell could be thinner but maybe not thin enough to overcome Ti's ~ 40% lighter density advantage. It should of have had a monolithic pressure vessel of known material with ballast and everything else taking shell weight into account. The ballast setup and several other design elements of the Titan were hokey and bound to fail ..
Regarding the matter of testing, here is a true story regarding 'Alvin', one of the world's first DSVs, when she was built in the early 1960s. Originally, three steel pressure spheres were manufactured for her, the idea being that one would be installed, one would be kept as a spare, and the 'worst' of the three would be pressure-tested to destruction. The test chamber was a massive thing, set in concrete, with a four ton lid. The sphere was lowered in, and the test began - the target being 4,000+ psi.
At close to that figure, the test chamber itself failed ....
The pressurized oil inside the chamber almost instantly dispersed over the entire neighborhood as a kind of fog bank. The four ton lid achieved lift-off, punched clean through the building's roof, got at least fifty feet further up by some estimates, then slammed straight back down on top of what was left of the test chamber, hammering it down a foot into solid concrete. Fifty-pound chunks of wreckage landed in the car park outside. Thankfully, no one was injured. The pressure sphere survived intact (!) - arguably the only part of the entire 'destruction test' to achieve that.
On the basis of that 'failed' test, it was decided that these pressure spheres were up to the job. 'Alvin' has changed pressure spheres several times in her long career since. All replacements have been thoroughly tested beforehand, but perhaps NOT to this degree. :)
All covered in the book 'Water Baby', which is the story of 'Alvin'. With 20-20 hindsight, a book that Mr Rush could have benefitted greatly from reading.
In "The Making of the Deep Submergence Vehicle (DSV) Limiting Factor - A Documentary by Nick Verola" th-cam.com/video/pb5j9oeZCm0/w-d-xo.html they took the titanium pressure vessel to St Petersburg and tested it to 1400 Bar which is over 20,000 PSI. He was happy to get it out of the country after testing.
@@hut8_newzealand361Thanks y’all, I wanted to look into this
Thanks a bunch for sharing that! I can't wait to get my hands on that book.
@@hut8_newzealand361 wow … ballsy to take it there but I’m guessing it was the only test chamber to achieve that depth… I’m going to check out the video now
This is great info,well done
The vibration damage theory is interesting. Ive recently been vibration testing large custom batteries and the first vibration test was a shocking catostrophic failure. Nearly every weld tab broke and shorted everything out. Upon seeing this we filled all voids with a flexible epoxy and tested again, it was mostly intact but there was a few wire connectors left exposed and they all vibrated to destruction and the wires fell out. My point is that vibration can be way more destructive than we might think. Solder connections are vulnerable and wire connectors can come loose.
have you bought a authentic piece of titanic coal?🤣🤣
I've opened my impact wrench a couple of times to tighten loose connections. Probably hundreds in the trash for a vibration...
@@SuperAfranks and stockton never got that fact vibrations can rip things apart mind so can compression and decompression cycles on the sub hull also do the same thing so he's dead and that's all that matters seriously
Vibration tables are way different than rocking back and forth while going over waves. I highly doubt being towed out to the dive site has anything to do with over-stressing the sub.
@@daves2433 the bouncing of waves would introduce shock but i imagine there would be alot of vibration too. Of course not the same frequency as a vibe table but same idea, just slower vibrations and at random intervals
From what I understand, UW did NOT assist with Titan, they assisted with its predecessor Cyclops, which was a steel-hulled vessel. The very weird thing about that, however, is in an article which was linked on an old version of the Wikipedia page for Titan, it goes into detail about how UW was assisting with Titan as well, specifically talking about its carbon fiber hull. The article was written years ago, something like 2017, but was updated after the implosion to indicate that UW only worked on Cyclops and specifically a steel-hulled submersible. Which means, either UW is lying and trying to hide the part they played in all of this after the fact, or they knew there was misinformation about their work on Titan out there for years and didn't bother to correct anyone until after the submersible imploded.
Your false dichotomy has a third options, they DIDNT know the misinformation was there and corrected when they found out about it.
Or it’s possible they didn’t know about the Wikipedia article until recently.
I tend to lying. Wiki is no realiable source of constant truth. Quite the opposite.
At least someone here is a critical thinker. I don’t believe Rush lied about working with Boeing and UW and even SpaceX. The language he they’re using is very telling. I think it’s all just an attempt to distance themselves from the whole fiasco
@@Hunne2303 I was referring to an article about UW's work with Oceangate that was used as a source on Wikipedia. This is how Wikipedia works. You read what the article on Wikipedia says, and then you check the sources they used in order to verify the accuracy of the information. In this case, all of the information I was talking about came from the external source, not Wikipedia itself.
Your TH-cam presentation is by far the ultimate in providing an excellent description of events that led to the fatal implosion. Job well done ! I will be following & watching the next episodes.
What utter nonsense … how can you say this? You got no actual facts, no knowledge about the design and construction process … what happened down there … as none of us have … the official investigation taking years … but you praise the quality of amateur youtube assumptions … its like using carbon for a sub … 🤣
The more information that comes out from this incident the more Stockton Rush deserves to win The Darwin Award outright, no contest.
Unfortunately, Stockton Crush won't qualify for the Darwin award since he had already procreated, thus didn't remove himself from the gene pool in a timely enough manner.
You're assuming that hearsay and speculation are evidence. The fact is that the only people who know anything are the government. That's it. Let the investigation go through.
Yes Stockton passed his stupid genes to the next generation. The human race is stuck with them

The fact the titanium collar was glued onto the fiber carbon hull with some fancy epoxy shocks me. I can’t believe it survived the first trip, let alone any after that.
My 1st posted concern, alarming.
Glued in with all the precision of a 6 year olds finger painting.
Epoxy is tough stuff
Guess you’ve never been in a ship
@@priceandpride lots of ocean yachts are made from glass fiber + epoxy
Absolutely believe that a long tow (length of tow line) through the open ocean will stress the hull much more than being stowed on deck. It's a bit shocking that OceanGate even considered it for an extended voyage. In a seaway, a ships hull is always "working", which means its joints, fasteners, glue, cables, shafts, etc, etc, are subjected to twisting, sagging, hogging, impacts, vibration, etc. Each of these could be described as an acceleration or some other force like compression or tension of the hull members. On deck the envelope and amplitude of those acceleration forces are much more gentle than those encountered on a barge dragging several hundred yards astern the mother ship. Imagine Titan bucking a moderate sea with perhaps the full weight of the equipment bay bolted to the aft ring? Those glue joints working for days on end. The through hull seals. The bolts. No one is there to witness, listen or inspect it's behavior. The mind boggles.
I don't know if the structure that supported the equipment to the rear (aft) of the vessel was attached to the carbon fiber hull somehow of just attached to the titanium end cap. Imagine the stress to that glued joint if a few hundred kilos of equipment were bouncing around hanging off that titanium ring.
@@mrbyamile6973 Ya, totally agree. It looks like its only bolted to the titanium ring, but that ring in turn is glued to the carbon fiber a few inches away, wrenching mercilessly at the joint for days on end. I think you're right about the weight of the equipment being hundreds of kilos - and it's suspended out there on a lever arm.
Jeff, being an engineer who spent part of my career in Testing, I fully appreciate your approach and detailed logic on the analysis of this sad event, perhaps, due to an ego and little engineering foundation of the CEO
The acrylic window was clearly shaped so that the external pressure clamped it more firmly to the titanium seating, and it was retained in place by a titanium ring, bolts and there was presumably a sealing gland of some sort. Whilst being strong in resisting external pressure, it was not designed to resist pressures from the inside. When the hull collapsed, the sudden inflow of water would have caused a sudden adiabatic compression of the air inside the hull, resulting in a very high temperature (estimated at 1700 deg K) and a shock wave that blew out the acrylic window from the inside.
Wouldn't that have burned the acrylic leaving no trace like incinerator?
This is what I think happened. Also since acrylic isn't that much heavier than water, it might have traveled a considerable horizontal distance before settling on the sea floor.
@@carriecree1789 I don't think it gets that hot for more than milliseconds, not enough heat to incinerate a heavy piece of plastic.
My thoughts too, probably the same reason the front ring and titanium hemisphere got separated, probably sheared the grade 2 bolts they used lol!
Exactly, in the Refrigeration Trade, I’ve seen some incredible damage due to a Shock Wave, holes punched through Copper and Split Steel pipes.
The pallets that the titanium rings have been delivered on ( 11:05) are some of the cheapest you can buy. They are too small - If you drive a forklift all the way into to pick them up you will damage the product and this happens very often with undersize pallets. And the method used to secure the rings using steel tension bands is also another well known way to damage the product. I work in logistics and I wouldn't even send car parts out to a client as shoddily as this, let alone critical components for a submersible. To me this is mind boggling, and it just shows what kind of companies Stockton Rush was dealing with. Those pallets with the rings looked like the kind of crap you get when you order parts from China.
So weird that they didn't even use edge protectors (even some 3-5mm thick cardboard) between the rings and the bands.
Chep pallets are the way to go
Outstanding observation! I haven't seen anyone else share this detail.
Very good observation
Nice observation and good to hear from someone who's actual job it is
The steel ring that bolted the window in place is missing in every photo I have seen. This would indicate that the window didn't implode. Either the window was blown out by the internal pressure when the sub imploded, shearing off the bolts, or the bolts were removed to make the end cap easier to recover, and if they were removed, that would imply that the window was still there.
I have to say that the expansion and contraction of dissimilar materials was the first thing I thought of when I saw the construction videos of them gluing it together. It surprisingly made many deep dives before the glue apparently fatigued enough at a microscopic level to allow complete failure. This would explain the repeating crackling sounds Stockton claimed to have heard in the aft moments prior to implosion, probably the rear ring starting to separate from the tube!
It hard to see a ring being pushed home by about 3000 tons (at the depth the problem has been noticed) separating from the cylinder .🙂 It is definitely easy to imagine how the glued joint started to leak causing the buoyancy problems. I think the cause of the implosion as such is a pretty much open question for which we may never know a definite answer.
No way for the ring to fail, it's being pushed in tighter and tighter as it went deeper.
Also, all the nuts holding the window in fact ere blown off. That had to happen due to pressure coming from behind.
The tube probably ripped open, and as the water rushed in the air pressure build up would have slammed into each end cap.
You sure it wasn't more than 300 tons?
I heard the entire thing had 50-60 thousand tons pushing in on it.
@@lordgarion514 You are right. Not "miscalculation" on my part, just missed one zero - a typo. Fixed it already.

They said that they had recovered "Presumed Human Remains". They did NOT say that they had recovered "Recognizable Human Remains". Any identification will be accomplished by DNA analysis.
Probably not even a finfger
Yeah I assumed just some kind of sign of humans having been inside one time. Maybe it’s some hair stuck in something somehow. Or a random bone. Yah prolly not even a finger though, maybe a bone of a finger.
Or teeth or something from a surgery made of metal. Honestly, I doubt even bones would survive.
Pretty dark, but I couldn't even imagine what they were pulling out that "we think these are human remains" was the description.
Yeah, they’re going to be picking up those “remains” with a sponge.
There were so many flaws in that Submersible, they’ll never find out exactly how it failed… it was gross negligence that caused this
They already know how it failed: carbon fiber cyclic fatigue damage and degradation.
@@johnbergstrom2931If the audio logs are true (big if), sounds like perhaps the glue joint failed in the rear between the CF and titanium.

This was some remarkable footage. I’ve never seen any of this before, it shows a very interesting manufacturing process.
It’s easy to see things clearly in hindsight isn’t it?

You are one of the few content creators that I get excited when I see a new upload! I imagine that you spend a tremendous amount of time researching, fact checking, editing, writing, etc… to which your viewers, myself included, truly do appreciate all of time and effort you put in to making this content.
I look forward to watching Jeff's videos. That 16 minutes really went fast and normally 16 minutes seems more like an hour on some of these You Tube channels when the content don't hold my interest.
Me too. I work for Lowe's, so I was familiar with this channel.
All of this Titan coverage has really blown me away, he has been a phenomenal reporter on this unnecessary tragedy.
I second this, best channel covering this stuff by far!
I actually look forward to his videos as well. And I see a lot of other commentary using his vids are well. I found Jeff after Champagne Towers collapsed. I love his vids!!
I found him after the condo collapse as well and followed ever since.
If the Titan was dragged across the surface behind the 'support vessel' then you have to consider the torsional stress put on the ends of the carbon fiber cylinder, due to the weight of the titanium end caps. The glue seals would be taking all of that torsional stress and getting weaker every second. That's not to mention the carbon fiber tube itself underneath and near the titanium rims as well. There had to be weakening of the carbon structure when the Titan was subjected to the rolling of its platform.
that's a very good point and would explain why the noises they heard were in the aft (on the basis of communication transcript) when the hull monitoring system got activated. The carbon fiber hull must have been weakened and perhaps the rear end connected to the titanium cap was the exact point of failure.
it wasn't, it was on it's support platform that's designed to be submersed then release the titan
@@joey24698 No, I did mean on the platform. I believe the platform's movement would have created greater torsional stress than the support ship deck. I wasn't very clear.

Excellent info and analysis. The word 'hubris' keeps coming to mind when I watch these things. So many red flags: 1.) the 'RTM's' and what, if any safety margin they provided. 2.) the lies about the CF construction process, wet lay up vs. pre-preg., etc. 3.) The fact the passengers were bolted into the vessel, making emergency escape at surface very difficult. 4.) The bolt diameters that secured the end cap to the hull. 5.) The fact that they towed the Titan out to dive site over the open ocean. Think of the wave and salt water action alone and potential risks there. 6.) Nargolet's having recently lost his wife and having had possible suicidal ideations, or at least a reduced will to live. 7.) Rush's insurance/indemnification policies, both suspicious. 8.) Rush's ignoring of warnings and concerns from experienced sub-mariners, both inside and outside his company. 9.) His family/deep connections to the Bohemian Grove, where an occult 'Cremation of Care' ceremony is performed in secret each year, under an effigy to the pagan god, Molloch. Occultism grows in popularity and the consequences of this paradigm shift may be more profound than the general public realizes.
Definitely my "go to" channel until we have answers!! Thank you for your well researched videos!! 😊
Please Jeff, do more documentaries. The world would absolutely love them.

The port window was likely blown out by the implosion. The acrylic window was only attached by small bolts (18?) and they bragged that the 18th wasn't even tightened because the water pressure presses inward, not outward. Well, if they weren't torqued, they become less tight as the flange is compressed against the dome. There would be far less strength to outward pressure, and the explosive pressure of the CF imploding would blow the air pressure against the window. Inspection of the threads in the dome for the window will reveal if this happened.
Jeff - Excellent coverage & images of the manufacturing of the Titan Submersible! As for the Ti Rings, I'm surprised that there was only a ~3" overlap with the carbon fiber hull. This leaves you with a very small bonding surface to transfer the loads through the epoxy to the Ti rings for both bucking and bending loads. It seems they were only thinking about compressive loads from the domes. Also, carbon fiber is not great for compression, it is the epoxy resin and not the carbon fiber that is resisting these forces. The conical viewport was PHOV certified to a depth of 1300 meters. These viewports are designed with a safety margin of 10X. However, there's a reason for this large safety factor for this transparent material.
Hi. Please continue forward with videos especially on Titan and Oceangate’s updates. We know that a thorough Investigation takes longer than a year. I appreciate your point of view and like the way you explain things
Thanks, I sure will continue!
A thorough investigation does not take a year. The Secret Service says that a whodunnit at the White House, for instance, can be wrapped up in as little as a week or two. Although sometimes a case is just too hard to crack, apparently, even on land & with tons of video footage, so don't get your hopes up about learning exactly what happened with Titan.
@@polarvortex3294There have been plane crash investigations that took YEARS to complete. 🤦♂️
Yes, most likely more than a year.
@@jeffostroffLove your videos!! ❤
look at how the rear assembly is attached to the mounting ring. that is insane, think of it bouncing around in the waves with all the weight on that joint.
I just remembered I had the same Coal and just went and checked just now. Paul signed my COA as well. I got the coal as a kid back in 97 or 98 possibly earlier as a Christmas present if I remember right. Thank you for this video. I never would have checked.
Awesome information - thx for doing the leg work on this - and sharing with us - am looking forward to following you as the formal investigation proceeds
I’m a boomer with no knowledge of marine craft, above or below the waves. However, I like to learn and my knowledge and vocabulary have increased following this story. Thank you for your videos. I look forward to learning more.
Like, a real Boomer? Born between 1945 and 1964? Me, too.
I arrived in '55.
Ah. The last generation that had time to be lazy and selfish.
Aside from the madness of towing the sub through waves and into debris, is that it becomes much more difficult for engineers to work on the sub before and between missions and means everything takes a lot more time. I would be surprised if they didn't decrease the number of checks in order to meet time pressures.I believe they switched vessels because they were required by Canada to use a Canadian flagged vessel rather than Panamanian or similar so the cost went up and the quality of vessel went down
ooo oooo here's a question can the acrylic windows survive an implosion?
Wow. The Karl Stanley interview was telling. Wraps up the analysis of Stockton perfectly; he couldnt be told anything, by anyone and was hellbent on doing “it” his way. Just imagine having potential at something, and then absolutely ruining it because you have to be the smartest guy in the room all the time… 😢
Such excellent and informative videos. Very thoughtful analysis!
I showed my dad the video you did on the transcript. He liked how you explained in details. He also liked your videos on the July 4th sales for Home Depot. He subscribed immediately to your channel
Awesome, thanks Army For Life!
In the released transcript, they said 2 or 3 times (before going silent) that they kept hearing sounds coming from the aft of the sub. Some strange noises that ARE NOT NORMAL. Within a few minutes after mentioning the noise for the last time, it went silent. Forever. Rest in peace people. I'm sorry it had to be that way.
AFT?
There's also other sources saying that transcript was fake though. So who knows.

@@MastaSquidgeit’s not fake
@swashington942 based on such compelling evidence as "its legit bro just trust me"?
Not one official has come out and said the transcript is real and nearly all who discuss it explicitly state that they don't have any verification that it's legit.
Excellent video, thanks Jeff.
Such an interesting video. Thanks for sharing!
The video of winding the shell (9:42) and preparing for the liner (10:50) are from the first shell build in 2017 not the shell that imploded which was built in Oct 2020 with different methods and materials to the same dimensions. The individual standing at the end of the shell at (10:50) is Tony Nissen, Director of Engineering, who left Oceangate in July 2019 per his Linkedin bio.
Okay wow
carbon fiber was still used. it was still done incompetently.
@@toomanyaccounts I wasn't trying to suggest that the 2020 shell was a good design. A carbon fiber shell under extreme external pressure is inexcusably stupid. Just pointing out that the shell fabrication many TH-camrs are showing and many viewers are nitpicking is not what failed. Oceangate tested the 2017 shell and it failed so Oceangate made some changes to the design and build a second shell based on there test results. Oceangate acknowledged cyclic fatigue of the carbon fiber shell was a problem and attempted to address the problem. There attempt was clearly inadequate. I'm not an expert in composite materials, but from what little info I can find on the 2020 shell fabrication, Oceangate addressed some of the complaints TH-camrs & viewers have made about the 2017 shell fabrication. Electroimpact has better fabrication technology than Spencer, the 2020 shell was cured every inch not all 5 inches at once. Prepreg carbon fiber was used instead of wet fibers, biaxial lay up was used instead of radial only lay up (there are contradictory reports regarding lay and materials). It will take a year or two, but like after a plane crash or building collapse, details of the causes of the failure base on all of the available evidence will evidence will come out. Everybody who designed and fabricated the the 2020 shell is alive except Rush. If the investigators from four countries don't find all the detailed construction info, the lawyers will. There will be books and maybe a movie.
Years ago I bought a piece of that coal too. I was an engineer at Motorola in Chandler Arizona from 1995 working on the Iridium Satellite Project for 18 years. Very informative and well presented. A quick google search by any prospective passenger would have informed them about the history of troubles and inherent danger of this submersible craft. No way that I would have considered boarding this very obvious unsafe craft.
Looking forward to more from you. Thank You and Best Regards
Thanks Jeff, another great video. Look forward to the next
Awesome video. Thanks man!
Your reporting is meticulous and seriously in-depth! Though extremely tragic, I appreciate your vast knowledge and expertise. Thank you for helping me to better understand a world of unknowns.
presumed human remains hmm scary cause what happens if parts of Stockton get given as some ones lived one😭😭
Love how detailed abd easy to understand you make your videos.
Glad you like them!
Jeff, you always produce interesting videos about this case.
your videos are great man, thanks for all the info!
Thanks Jeff.The plot thickens as they say and I am really looking forward to not only your videos,but the future reports about this totally avoidable tragedy..
Uhhhh .... it won't be known if it was "totally avoidable" until the investigation finds what caused id.
@grizwoldphantasia5005 YES avoidable. Making a sub from carbon fiber is equivalent to making it from wound rope. Rope is great under tension (stretching) but lousy under compression. Carbon fiber is the same
.
Also if the CEO had tested the sub at depth unmanned, then studied the results, he would have seen it was delaminating. Because that’s exactly how carbon fiber fails in other deep dive in-lab testing. It doesn’t work
.
@@grizwoldphantasia5005 Obviously, you have not been following this story for the past four weeks. He ignored the warnings of dozens of experts, his own engineer, and did things no one in the industry would dream of doing as far as the construction of this thing so yes, without question, this was completely avoidable, but obviously the way things were meant to be otherwise it wouldn't have happened.
Such a tragedy! No submersible should be taking anyone down to these depths unless it's been certified. Period! My condolences to the families.
If someone wants to do it themselves thats fine, they can risk it if they want, but to potentially lie to, and bring OTHER people on board is just evil. I really believe stockton would be going to prison if he was still alive.
At a certain point safety is a waste.
@@VashStarwind Agree 110 %. Greed. He was offering TH-camrs discounts to go. That says it all.
Absolutely, if it ain't certified by the US Navy, I'll pass.
@@VashStarwindI agree. Nobody should have the authority to prevent you from going in the damn ocean lol. But don’t take other people with you
Thank you for the update i can’t believe it happened
I have really been enjoying your videos on the submersible. Please keep doing these. It's very educational and interesting.
I just had a thought regarding that leaked transcript. Alot of the dialogue seems like something a pilot would say "Enjoying the ride", "Happy crew", etc. Rush had and aviation background so it would make sense that he would say these things. He also wanted to commercialize his operation and I could see him using those terms to distinguish his operation from military/scientific operations.
Might be a little less than 'evidence', but it''s an interesting nuanced detail that I've never heard anyone bring up.
FWIW, I know Snopes debunked it. but I think they are biased and they were qiuick to jump the gun as they usually are.
If there wasn't the video of them inside the sub showing full sentences I'd agree with Snopes right off the bat but that muddies things.
@@tonymorris4335 Snopes's inherent bias is that they are more focused on debunking rather than the truth.
The transcript codes should not have been considered evidence as Rush very clearly ran a non standard operation.
It would be like me saying they didn't use a carbon fiber hull because it's not rated for that depth and would be a poor choice material.
We know that isn't the case because he broke a lot of rules. Transcript codes are no different.
Something can't be debunked unless the facts are known. Unless someone involved in the project confirms that the transcript is fake or real Snopes doesn't know any more than the rest of us.

Great video-- very informative!
Your mention of working for Motorola and the shaker tables reminded me of my time working for Hughes Network Sustems. My favorite department was the guys testing equipment off the assembly line on the shaker tables and environmental chambers. Cook it, freeze it, shake it. Those guys had a great job. Test it, break it, figure out why it broke.
As far as the window, remember all warnings were coming from the aft, the RTM was alarming for the aft section. If the aft give way at the carbon connection the carbon would’ve first collapsed inward causing the window to in effect pop out and landed on the ocean floor. When viewing the video of the wreckage the window is missing and so are the bolts!
Warnings? The message transcript was completely fake!
So the window was popped out possibly before the soda can part could collapse?
@@jonsimon5779 Nope if the window popped out then it was because internal pressure exceeded the external pressure, i.e the soda pop can crushed and it popped the window out
Wow, Jeff! They towed the submersible???!!! At this point, this case is involuntary manslaughter, or criminally negligent homicide. As you stated, a wonderful way of stress testing an assembly of different structures is through vibration. Another is failing to pre-stress the longitudinally-woven CF hull while being transported. As the hull flexes around its mounts, as the tow craft attempts to ride the waves, I see the weave beginning to separate. Stockton Rush was not just a narcissist who thought Standards are onerous, he believed him and his clients should chance an untested design that he used humans as unaware test subjects!!! In another video, by the Sub Guy (?). Rush matter-of-factly would state the portal window would routinely and visibly flex inward to the cabin. I believe the CF hull separated near the thrusters, taking on water, then began cracking in the center, then finally failed, and the vacuum pulled the portal window through the passengers, embedding their remains on the portal's fragments. You will eventually get called for expert testimony, so, if you have not done so already, retain counsel to directly refer any inquiries, both from victim's families and the plaintiff(s). Great job; Moto trained you well.
I doubt the window was sucked in; more likely the implosion reaction blew it out. There is no way what looks like 3/8" bolts spaced 6" or more apart would hold 6,000 psi in tension for that amount of area...
Stockton Rush himself stated the portal, which was only rated to about 4000 ft depth would visibly deflect toward the cabin. Assu the hypothesis is correct, where the passengers were clustered around the portal, as the sub descended nose-first, the only question I have is where are the remains. The implosion would pull any fragments toward a "virtual comparative vacuum.". Did the implosion occur on the way down? In that case, I believe the CF fibers would be like knives or shrapnel moving through the passengers. If they made it to the sea floor, I believe the already stressed portal would propel upward, at the same time the CF hull implosion occurred. I still believe the portal is not being shown as it contains the passengers' remains. 🙏
They also towed it around shows on the back of a truck IIRC? Years ago, I used to work for a company that moved instrumentation via road, and this led to failures due to vibration damage particularly when unsealed roads were used.
Thank you for your updates and sharting your investiogations.
Oeps, must be "sharing" and "investigations". Sorry.
Great work! Very informative. Thank you!
Someone commented elsewhere that when they went to see the Deepflight Challenger on display somewhere, Graham Hawkes was really fussy about anyone getting too close or touching it, because the carbon fibre was so fragile that even the slightest knock would mean they'd have to go back and spend a fortune on ultrasound testing again. One of the reasons composites aren't used that often in pressure hulls is the expense of inspection and non-destructive testing (in fact the Royal Navy eventually rebuilt the LR5 rescue vessel out of steel instead of its original glass fibre hull, which had been in service for 25 years at that point, simply because steel only needs x-ray inspection of its welds, rather than a full scan of the material), so God knows what all that battering the Titan took during all that dragging about in rough seas. The Lloyds certification on the commercially available Deepflight requires a new inspection every 8 years, but given that their Challenger was a one-off meant to be used only once, I reckon that even if the Titan had been built properly, it would have needed inspecting after each and every dive because of the brittleness of carbon fibre and the depths involved. Rush told everyone that the appropriate equipment didn't exist to inspect the hull, but that's not true; it just would have set him back $20,000 a time, plus, I suspect, he knew it would prove him wrong. David Lochridge in his leaked email, mentions inspecting the hull simply by shining a bright light through it AND SEEING LOADS OF CRACKS AND VOIDS WITH THE GODDAMN NAKED EYE!
EDIT: The acrylic porthole would TOTALLY cave in on an implosion because the one they were using was only rated to 1300m due to rush refusing to pay for one designed for the correct depth, justifying his decision by claiming they'd see it start to fail visually and have time to return to the service. Oceangate's entire safety precautions were dependent on finding a failure AFTER something bad had happened.
Could it have been Stockton Rush's plan all along to continue diving in this dangerous situation until they inevitably all died and then he would become famous? He will be famous as long as the Titanic is famous now. He will forever be a landmark on a landmark. I wonder if he always wanted that to begin with...
Mr Rush is famous for being cheap, but taking money and lives. I can't see anyone with his ego wanting to be remembered for such things.
Machinist, welder, and childhood builder of model airplanes here.... I'm gonna go ahead and toss my speculation into the ring just for the heck of it. The sms messages said they heard crackling sounds from aft. Other previous passengers described it as noisy with cracking sounds all the time even on ascent and at shallow depths. I speculate that, under load, the cylindrical composite portion of the hull was deforming into a slight hourglass shape or, maybe, a "pinched hose" shape. I further speculate that this caused a situation at the glue joints where the corner of the hull material at the inside diameter acted like the fulcrum of a lever, with the longitudinal axis of the hull walls acting as the long arm and the 5" "end grain" acting as the short arm. At half of the length of the 7.9 foot long hull tube you get a leverage ratio of about 10:1 at the end, trying to separate the glue joint at the outer edge. These members are all flexible so the actual forces would be lessened but I think everyone can agree that the ratio is such that the glue is fighting an uphill battle. The unusually fast descent and slow ascent after ballast and frame drop suggests that they were taking on water and, since they weren't visually aware of it, I think it must have been contained behind that rear interior wall. Once the rear dome glue joint let go I would think you would get an affect similar to "water hammer" in household plumbing that popped the acrylic window out from the inside as this would have been the weak direction for its mounting strategy. I'm going to guess that they haven't found the window because it is very heavy for it's size, probably hit the bottom with some speed, and ended up below the surface of the mud or silt or whatever is down there. This concludes my completely unqualified analysis. Thanks for coming to my Ted talk. Let's hope the authorities release a completed analysis at some point.
I can't wait for the full details to be released. So much info will come out soon enough.
great work, Jeff, thank you!🙏and wow, that Karl Stanley interview.....when he says that the ship topside probably heard the implosion sound coming up through the ocean, in real time, that sent chills!!
Karl lolzzzz th-cam.com/users/clipUgkxkmjGctOUSAj5pYlQ85JbH8sSQ4GXPlnp
Most likely the porthole exterior retaining ring was blown off by the post dieseling effect after implosion, the fasteners were designed for external forces only, the end cap images after being retrieved, show no fasteners, suggesting the threads were stripped out.
Excellent material and representation, thanks for sharing.
well atleast the port hole acrylic survived for the most part which is shocking when you think about it cause it was rated for 1300 meters and it out lasted the titan sub itself which goes to show the build quality in it over the titan sub🤣
@@raven4k998 I’ve been thinking about that. One of the few parts that was individually certified, and tested to be able to withstand specified conditions with an extensive operating range apparently had an appropriate 3x margin. Which is why it held up in use at 3x the rating - but likely at the far end of its capacity.
Here’s what blows my mind, the main hull was made using carbon fiber. We use that in the fire service, that’s what our scba’s are made of. They are better with inner pressure pushing out, not outter pressure pushing in. They went down way to fast and the carbon fiber hull couldn’t handle it.
The sounds heard on previous dives could point to the carbon fiber weakening with every descent until it was too weak enough to survive the last dive, even if just barely.
There's also the fact the carbon fiber in the hull was spun around vertically like a spring. Typically, the strength is maximized by having carbon fibers arranged in different directions. That allows the fiber to help hold itself together similar to yarn in a sweater holding itself together. I'm guessing the method used on the Titan was easier, faster, and cheaper, but it also resulted in a significantly weaker hull as the resin had to do all the work keeping the fiber from unraveling.
And you know for sure on a high-pressure bottle made of carbon fiber it can only stand pressure pushing out and not in why please explain Mr. Fluid dynamics expert.
Why do you think it descended so fast?
@@donraptor6156 I’m not 100 percent on that, that’s why it’s called a theory or an opinion. You do know what those terms mean right? Google it if ya don’t. Also been using carbon fiber bottles for over 20 years and the pressure inside those bottles are tremendous.
@@tsunamis82 mechanical failure, possibly something with the computer system, maybe Stockton wanting to rush the process to get them down there a little faster? We may never know, we can only throw opinions and theories out there.
The way the porthole window tapers against the hull, makes it very strong against inward pressure and weak against outward pressure, with just adhesive and a bolted ring holding it against the hull. My guess is, the carbon fiber hull section imploded in the middle, and in the milliseconds following that, superheated and compressed oxygen-rich atmosphere within momentary combusted, creating 2 immense pressure zones on the titanium "end caps". I believe that's why we're seeing such a clean separation of those from the carbon fiber hull, and no sign of bonded carbon fiber or porthole window.
Ice breakers are the tanks of the ocean. Their construction is considerably more robust than other ships. If I were going to buy a ship for working at sea, It would be a retired Ice breaker or Coast Guard cutter. They also typically have an observation room at the bottom of the hull at the bow for Ice depth visuals. Technology id nice but seeing in person is an experience that's awe inspiring. As for the rest...the arrogance of one man has ruined many lives and the only good thing that will come from this is that it won't likely happen again.
Icebreakers may be strong, but the hull design is a nightmare in open sea, extremely uncomfortable for people onboard and that vessel had zero benefits for this application other than being cheap... The massive AHTS vessel "Horizon Arctic" they used the first years was built in 2016. It is designed for offshore use with state of the art equipment onboard, and is basically the perfect vessel for the task. Of course, Stockton did mention that the operating cost for the Horizon Arctic was 1 million pr week, which seems about right. He could operate the Polar Prince for a fraction of the cost...
Great points. Unfortunately though as James Cameron pointed out, the wreck of the Titan has parallels to the wreck of the Titanic. In both cases, they were warned, but arrogance, money, and stubbornness led to the loss of the lives of other people.
But I believe that no one will again take passengers on a submersible made from those materials.
@@lindag9975 For years I have said "stupidity kills itself & arrogance kills others. The sub should have been remote operated during a years worth of testing at depth and then cut apart to inspect for flaws. hopefully some standards will be in place if this is ever tried again. They would have been better off leasing a sub from the Cousteaus or at least something from Wood's Hole if they have subs that are capable.
@@Kowalski301 I had no idea that they were so problematic on open waters. Thanks for the background info. Was the Calypso being a former Coast Guard Cutter/ ice breaker a nightmare too? I always liked that ship from a spectator's point of view.
I'd like to see an investigation involving recreating the carbon fibre hull to perform tests on. It will be interesting to see what pressures it can withstand and the resulting symptoms the hull experiences due to these pressures.
Thank you for linking to that ACE video! I saw it a few weeks ago then couldn’t find it again… I thought it got taken down.
You're videos have been the best and most informative on the Titan tragedy that I have seen. Awesome stuff man and thanks for making them!
I worked for a bit at a place making fibreglass containers the size of a minivan. I was a mandrill operator at a place called spell products. They were making tanks which hold water but even they would put on different layers of fibreglass at different angles. So some passes it would be straight but then they'd move the head so it was going on diagonally.
Yes much stronger.
If I am not mistaken, that is how water softeners are made. At least the ones I have seen.

could you imagine your containers only working for seventy trips? well this submersible would beat your that tub at golph as it can do astonishingly and shockingly low seven.
THe only thing else I have to sway is tghe difference between a subemarine and a submersible if a sub went edown to submersible depths it would get crashed, but a submersible can go down and back up both depths.
@@mal2ksc yes and wrong shape also as it needed to be a sphere.

The more i hear about this sub the more i am amazed that it lasted this long. Also, i would be honestly surprised if they find the window. Not because its broken. But because acrylic like that will be almost invisible under water
meh this is why you want to do what stockon did now you know don't do it it's not worth the lives it will cost it's cheaper to just splurge on a titanium sub like ballard has instead of carbon fiber as it will last a whole lot longer and thus be much much safer then the titan sub also do not call your sub titan call it scruffy
@raven4k998 - liking this comment for the “call it scruffy” part lol
14:28 For most of us, this event is a curiosity but for the deep submersible community this is a major event that will cast a shadow on them even though they have nothing to do with it, so my impression is that they're pissed, like we hear in this tone of this guy's voice.

@@jeffostroff was looking for a more in depth video about it. 👍
Great videos btw , I enjoy them
Considering Titan got lost and couldn't find the Titanic half the time, I wonder how they were able to make sure their ballast landed in the designated drop zones and didn't fall right into the wreck.
Didn't Rush get caught on the Titanic one time??
I believe the acrylic is likely intact. The adhesives used to adhere the carbon fiber and titanium likely failed before the acrylic did
Awesome rig 👍…. Really enjoyed the video
I have been following this since the sub was reported missing. A lot of this story is hinged on the fact that this sub was headed to the titanic when it imploded. I find myself wondering if this would be as big a story if it was average people in the sub visiting any other ship wreck. None the less a very tragic story with one hell of a salesman at the joystick.
I believe it would definitely be a smaller story. Possibly MUCH smaller.
In my opinion, the window didn't fail. The little evidence that has been seen points to a main hull implosion. If the window had failed, the outer retaining ring holding it on would more than likely still be there, or at least pieces of it had the pressure entered through that portal. A failure in the hull would have pushed the tapered portal out from the inside and ripped off the retaining ring, which seems to be what happened.
I personally think the obvious happened. The carbon simply failed spectacularly, like it is known to do. That force may have sheared off the retaining ring. We might expect that the 17 bolts were of a lower spec than they should have been. I don't know that, but based on what we do know if wouldn't be a shock.
Not necessarily. As soon as the implosion occurred, it would trigger a powerful shock wave which would immediately destroy the carbon fibre hull. The acrylic dome, according to a German scientist who modelled all the components, stated that the dome was only rated to 1,300mtrs. With 6,000psi on the dome, it's highly likely it gave way, especially as this was the 3rd time it was subjected to this pressure.
If you have ever run over a full bottle of water with a car, watch what happens to the cap. That's likely what happened. It got squeezed in the middle and POP went the end. The weakest point will fail first. And no way would the window be removed by the salvage team, they could have easily put a net down and hauled the end cap up if the window was intact.
The Titan was not designed for riding on top of waves, there is a reason why ship hulls are designed the way they are. I think it is definitely a chance that the stress of being dragged along like that could have contributed to the accident.
Titan sub wasn't designed for anything except being a casket
I heard they ran out of funds to have the Titan in the mother ship like it was previously. It then was towed behind and subjected to many environmental hazards while being towed.
Titan was strapped to a pontoon as can be clearly seen. All the allegations is was banged around are baseless until proven. With the rough seas and the small size they had to get it tied down pretty seriously.
So I cannot see why Titan being transported (not towed by itself) could be a major factor.
I find it a little misleading if not outright false to show people on board the mother ship who were free to roam and being tossed around and allude to Titan being tossed in the same way. Being an engineer myself I find this cringworthy and tabloid like reporting.
I can see that Titan being much more rattled and violently moved with the little pontoon might have its influence. I am more concerned about any appliances becoming loose or banging on the hull than that being able to compromise the pressure hull per se.
But we don't know until we know.
A bit too sensationalistic. No cigar.
@@laurenallums5235 yes, oceangate was originally using Horizon Arctic which was a much nicer and more expensive support ship which could carry Titan. They downgraded to the cheaper Polar Prince.
I've heard they dragged the submarine that way to avoid some regulation that could make Ocean Gate subject of port AUTHORITIES
Absolutely watch the 2 videos by 'Ace' of this interview, and a dive. Very VERY insightful about the cavalier and dangerous behavior of Rush.
Jeff, I like your elaborate analysis. That acrylic window is probably intact somewhere on the bottom of the ocean near the Titanic. That window is fixed to the the titanium halve with a stainless steel ring with 16 bolts. With normal water pressure from the outside this window will be pressed on to it's seat. However when the carbon fiber started to give way, the pressure inside the vessel went up, to the level of the water presure, causing the force from inside the vessel onto the acrylic window, breaking the 16 bolts and popping ring and acrylic window out. If the the window broke and scattered we would see the ring still in place on the titanium half. If you look at the recovered titanium half, there is no ring and no bolts. Either they disassembled it when it was brought up ( not likely as you temper with the evidence) or it popped off on the bolt and ring and acrylic window are still down in the water.
Don't forget that the acrylic plug can be both blown out AND shattered. The force required to shear-off those ring bolts would substantially damage mere acryllic. At best, the acryllic plug will have corner damage, buit probably is in shards, along with the carbon fibre hull.
There is that footage of gluing that titanium rings it showed the guy wiping down the surface with a rag (presumably soaked with alcohol) before the gluing process with the other hand lagging behind redepositing grease / oil back onto the surface.
Even with mountain bikes, it's stated hundreds of times to never touch the surface of the brake rotor as the natural oils / grease on your hands will ruin the brake pads.
