- With no certification from any regulatory body and a history of system malfunctions, questions linger over the Titan tourist submersible's safety conditions and its deadly implosion.
The debris of the sub was discovered by the U.S. Coast Guard, confirming the deaths of the five people on board.
Eric Sorensen speaks with industry experts about what could have gone wrong, and the criticism towards OceanGate Expeditions, the company that built the vessel.

Deep admiration for David Lochridge, the former OceanGate employee who both spoke up about saftey issues & then stood his ground after the company fired him! His actions as a whistleblower & beyond required several degrees of strong character. Not easy to do what he did. If more people were like him, the world would be a better place.
Yeah but he is an old white guy so he got fired
Also
Did he stand his ground
You'll notice he stopped having any issue with safety the moment there was a settlement
Rich people dont like regulations

@@stephennichol3620 Pretty sure regulations feel the same way about rich people so it balances out, basically.
It really is a shame that people died because some CEO didn’t care about safety. Could’ve been easily avoided.
Yeah, they read, sign the wavee and still went.
Pretty much all CEOs operate this way. Rather it be Oil companies, Railroads, Chemical plants, airlines, or others. It has and will always be profit before safety. Until they come down hard on these greedy bastards, this will continue.
I read your comment and thought, how interesting.
The same thing could have been said about the Titanic herself
and many other disasters that have occurred, come to think of it.
🤔
probably not easily avoided. It is a new frontier, sooner or later it was going to happen.
1 man’s PRIDE
“The events of the Titanic disaster can be seen as a symbol of what happens through overconfidence in technology, complacence, and a mindset of profits over people's safety.” Deborah Hopkinson.
Ocean Gate was so blind with the Titanic that they didn't stop a minute to understand the lesson.
Facts
The vessel was submitted to huge pressures while down in the deep below the surface. Over time, it weakens the hull structure and in doing so is asking for an accident to happen. Under thousands of pounds pressure while deep in the Atlantic 2.5 miles down and then after resufacing the pressure is only around 14 lbs. pressure. The rise and fall of pressures is like bending a strong p[iece of wire, that will give way once flexed enought. Each bend of the wire weakens the wire's strength more and more. The same applies with this small sub. the pressure building, and unbulding during a dive run, weakens the hull, and it only takes a micro dot of a weakness to have the sub implode iunder heavy pressure. This tells me that the sub was used once too many times in deep water.. It was the constant varying of hull pressure that caused the hull to weaken and give out.
I heard this same sub was to the Titanic about 15 times, maybe more. It had some bogus safety device on board to tell the Captain if the hull was becoming compromised, that obviously was not enough to stop it from imploding.
@@TutorialTreasury I personally had a business in Marine GRP (which is "Marine Glass Re-enforced Plastics" or better known as Marine Fiber-glassing and structure reinforcement with gel coat spraying and repair finishings in marine boats. I not only made fiberglass boats from scratch, I also repaired them when damaged. Anyone in Fiber-glassing would know the answer as to why the hull gave out and imploded. It's like with Fiber-glass, the hull can only take so much punishment after time and time again having to both expand and contract under the heavy pressures of deep-water diving. With each dive made, that hull weakened till finally it gave out and couldn't take the stress of high pressures being placed against the sides of the hull in deep water. Each deep diving sub has a short life span before the hull will finally give out. It could be a small flaw in the hull the size of a pin-head that could have caused an implosion of the sub's hull under high deep-water pressure. As the sub dives deeper, and deeper the pressure created would try and crush the hull and once it came back up to the surface, then hull would relax and expand again. If you attached a block of soft plastic foam to the outside of one of these deep diving subs and dove down a mile or two into the deep water, when you came back up, you'd find that foam block would have shrunk to a fraction of its normal regular size due to the high pressures of the deep crushing it. A 1 foot block of foam could easily become the small 3 inch block of foam after a dive like that. Maybe even smaller in size when it came back up to the water's surface. With every foot the sub sinks into the depths, reduces the size of that block of foam and it's all water pressure doing it.
@@tonyrame7548 It would only take a flaw the sized of a pin-head located in the hull to weaken the hull enough to implode the whole sub. With each dive it made since it was first launched, that sub's hull was weakening. These subs have limited life-spans under huge pressures of thousands of pounds per square inch against the outer hull. Place an egg on a table and start applying hand pressure evenly against the sides of the egg, and you'll see exactly what I mean. Your weight along with the pressure your placing on the sdies of that egg will crush it, once the max limit it can with-stand collapses. POOF the egg is destroyed. Same applies here regarding this sub. If yo take a 1 foot cube of a block of foam and tie it to that subs hull and made a dive at least 1 mile down, the water pressure against that foam cube, will cause that cube to shrink in size. You may have started out with a 1 ft square cube of foam when you started but once you came back up to the surface after a i mile down dive, you'd find that 1 foot cube would have shrunk in size like crazy to a fraction of what it began out being at the very start all due to the extreme high water pressures at those deep depths. That 1 ft. sq. cube of foam could end up being the size of a small marble once it gets back up to the surface. It would compress and reduce in size with each ft lower it dived into the lower depths. I say that sub should have been scraped long ago due to stress Fague it suffered from in being at those deep pressurized depths. It would only take a flaw in the hull the "sized of a pinhead" to totally destroy that sub under those deep high pressures. That's thousands and thousands of pounds per square inch of pressure applied on that hull at that depth. Those inside wouldn't have time to know what was happening. It would be instant death for each of them. Gone in the blink of an eye.
Yes, although keep in mind that the Alvin submersible that was used to explore the Titanic after its initial discovery has made thousands of dives over the past nearly 60 years. Presumably, it had a better design to start with, combined with better maintenance and monitoring to verify that it wouldn't fail under pressure. From what I can tell, the actual place where the crew sits is in its own sphere made of metal with minimal openings. In other words, a ton of good engineering decisions that likely will allow it to keep operating for years go to come. (Admittedly at some point the entire craft will likely need to be decommissioned, but 60 years is a rather impressive record compared with the Titan sub failing after only a few dives)
@@waynedavies3185 People who aren't engineers usually don't understand the way that stresses travel around surfaces. I'm not an engineer, but I remember listening to an expert talking about the difference between drilling a round hole in a slab of concrete versus a square hole and the implications that has for cracks forming. The same thing occurs with pretty much anything under some sort of stress. Just a little weak spot can grow to a large size in the blink of an eye if there isn't sufficient resilience built into the design. I remember the way my parent's house was completely without support on one corner due to dry rot and you wouldn't have known it without seeing the siding removed because of the redundancy that is in standard construction designs. (Not that it was a good situation, but that it didn't result in a critical failure of the structure)
The owner of the submersible did not have it certified. In my amateur opinion, this tragedy is on him and his company.
RIP. Unforgettable.
Unforgivable is the word your are searching for.
Really sad when the CEO of Oceangate says he broke a lot of rules to get this sub launched
This is “business as usual” for most companies. Cutting corners for profit is the norm for most companies especially wealthy ones
It was CERTIFIED and it was CERTIFIED by nazi
Ceo was anti-white labor as well
British experts had already tested the carbon fiber pressure hull approach and discarded it since they found delamination after repeated dive cycles. It was a matter of time.
And hair line cracks in the carbon fiber
To wrap fiber around a tube wont increase much its ability to sustain EXTERNAL pressure !
@@HeavyHaul51 Cracks Don't propagate in carbon the way they do in metal. There is no fatigue life proper. If the crack penetrates the first couple of layers of carbon fiber or a couple of layers delaminate, the next time you load it, it is just going to instantly shatter.
This is why real subs are metal. Metal dent but don’t crack easily.
@ninatote6426 means layers coming off slowly
I would be furious if I were the mother of that 19-yo. boy down there. Fair game for old men, but selfish and unconscionable of his dad to coerce him to come along at such a tender age.

I truly agree
Guess you could say peer pressure was the least of his worries
what’s with people having zero empathy for men of a certain age dying? odd
It was the incompetence of the CEO that ignored warnings from experts that the submersibles they had were not safe!!!
In 1912, the “unsinkable” ship sank. 111 years later, a submersible vessel imploded while attempting to tour the remains of the first vessel. RIP to all the victims of both vessels.
Really sad.
Kinda funny, tho.
Arrogant billionaires were the cause of both! IRONIC don't you think?
I swear the water is haunted
Both perfectly avoidable.
From the beginning I wanted to open the news and see headlines they were rescued and okay. What a tragic loss.
Is it odd that I pictured them alive being interviewed? Like, I could picture the ceo getting sued left and right as he walks to the court. The others telling their story. I'm sad about the outcome. Very unfortunate
Same... 😥
The loss of communication to the mother ship was a huge red flag of disaster.
Makes me wish they'd require a tether on submersibles, especially if it gets caught in a net or wreckage and needs to be retrieved.
PFFfft.
@@niftynifty3106
What does that mean??
My personal theory is that the CEO and captain was possibly narcisistic and found that niche in experimental tech where you can be a guru and people flock to you and you get a lot of praise and attention. This can lead to an addiction to technical progress to maintain the attention. This leads to the taking of irresponsible risks.
There are parallels with for instance Peter Madsen ('innovative' rocket and submarine designer, who killed a journalist on his sub), Elizabeth Holmes (Scam with 'innovative' medical tech) and Bernie Madoff (Ponzi Scheme based on 'innovative' banking tech).
👍
Stockton Rush was mentally unfit.
I remember, when I used to work private security at a building with a lot of offices, how much of a pain these CEOs of smaller companies could be. They'd just assume that because they could largely do as they liked at their headquarters that the same would be the case elsewhere. It was always immensely satisfying to tell them no and to f-off as the building owner and management wasn't going to have any of it.
It sounds like there was a lot fo that going on at this company, where the people who would say this was a horrible idea got fired and in at least one case sued.
Your projecting 😂
It's very sad. My thoughts and prayers are with the families and friends of those affected.

I heard that in 2017 One person in the company raised the issue of structural flaws in the submarine no one heard him and he was removed from the position in return
David Lochridge, look him up ;-)
It was both the pressure and material fatigue--the structure of the hull takes a toll with each subsequent trip. The company got complacent with the previous voyages, overlooked critical aspects of the safety of the sub, and ignored warnings from other experts in the field. This tragedy is actually the first instance in deepdiving history that the vessel suffered a catastrophic failure. There needs to be better regulations of this industry.
There already are tons of regulations in place. These idiots tried to skip those.
@@Kaixfikwind That's true, but sadly the regulations are not enforced and OceanGate managed to make three trips down there, without getting the vessel certified for that depth.
Carbon Fiber is not a material that should be used in that kind of high pressure environment.
@@EheTeNandayo867it is in international waters. Nothing you can do
Absolutely correct, those depths particularly the Abyssopelagic and Hadopelagic zones are the most unforgiving in the extreme, there can be no room for error or complacency when it comes to redundancy and structure of the diving vehicle.
Truly tragic. I was hoping to see hugs, families crying, hearing their scary stories if they were found. Now they became one with the Titanic forever. We’ll be seeing this in the movies in the near future.
I would simply have taken a deep breath then Houdini out of the submarine, swim to safety while I held the sub with my other hand
I sincerely out of respect for the Lost that the Families Never give permission for such a ghoulish subject for a movie.
Would probably be the most boring movie ever considering the implosion happened in like half the blink of an eye
We bow to you, Edge Lord. Now go have mommy read a book to you and go to bed.
@@JonnyBravo-ky2mkwell the sub is bolted from the outside so you couldn’t get out from the inside even if you surfaced (unless you are superman)
It's called fatigue of repeated, dynamically loaded structure.
It's unfortunate but no mystery.
Seems to me Stockton would have been fully aware of this. Seems to me he literally just ignored it. Seems to me that it makes him a serial killer.
@@samscarletta7433 could very well be.
I guess that's for the courts and governing bodies of sea vessels to decide.
One thing is certain:
The owner strongly believed in his sub. Otherwise he wouldn't have gone on the dive.
But he also said to stay home if you wanted to stay safe
He succeded before but began to be cocky
Hubris is a terrible thing and can get you killed.
He didn’t, before his death he said multiple times that “life is not life without risk” and other various quotes going against what you say
For the CEO his company made 1 million dollars for just this one trip alone. Four ppl at 250k each.
In short, the submersible may have been crushed by a pressure force of almost 414 bar or 41,400 kPa. That force would destroy almost anything in a blink of an eye.
At least it would’ve been quick.
@@emb5048 Quicker than the speed of neurones, so they wouldn’t have even known it happened. Within milliseconds. Painless.

they were disintegrated so quick they new nothing. its scary
Imagine just being alive, able to know what's happening around you... And suddenly, boom, nothing... U just get deleted, u don't even get to compile what happened... Oblivion...
We need animation to show the impulsion. 🙏
One question rankles: If the US Navy did know about the implosion of the day the Titan was descending in the water then why didn't it put this forthright? Since when has it started to decide that let's use public resources and shape public opinion around a tragedy until the last ounce of oxygen has been squeezed from this story not to mention prolonging the agony of the families. Or was it decided by someone powerful that they needed this story to escape public scrutiny on the high profile Hunter story?
Because the ocean is large. Hearing a loud noise does not automatically mean it was them.
Jesus give it a rest you fruit loop
Info gathered by secure means is classified. It's relayed up the chain of responsibility.
@@rebeccatyndall420 Agreed but when one hand is searching and calking for international.assistance in the search then its beyond understanding why the other hand is withholding the most pertinent information related to that search.
Crazy how we never heard of this 5 years ago until now

There already ARE standards. They literally ignored all of them.
RIP to all. So sorry for the families left grieving their loss.
AMENx
the pressure was so powerful when the vessel imploded, it was like a lightning strike. they didn't even knew what hit them
This seems to be an issue of material fatigue.
Minor, hidden damage builds up over time.
See another example of this from 2023 when a giant fish tank collapsed after over 10 years of use at the Raddison Blue Hotel in Berlin.
Yes- we know. You aren’t saying anything new.🤦♂️
@@spanqueluv9er thanks for adding even more value than I did
Maybe because they did not follow the design plans and made it 2 inches thinner and the view port was rated 1300 meters not 4000 meters. So either the carbon fibers cracked or the view port did.
That would be the Achilles heel. When that failed, the rest imploded like squeezing a raw egg in one's hand.
Catastrophic Implosion
I would say it was almost certainly the carbon fibre that failed.
The viewport was unlikely to fail under the same conditions it had already experienced - at least before the carbon fibre (it essentially won't fail unless you go to deep at least comparatively to carbon fibre which becomes noticeably weaker). I'm by no means certain about that, just general understanding of the materials.
Whereas that is a very real and acknowledged issue with carbon fibre (especially if it had flaws during building, deteriorated after each cycle or was being used near its maximum capability).
@@stan4nowiam a submarine Engineer and I am making a good one to go to titanic below. U can register to come
Sure, discard safety concerns, present your waiver and charge millions.
And voila, you are in business !!
@@shahminhajuddin shut up
They've been eaten by a sea monster lurking below the depths of the ocean for all we know
Two (titanium caps/ carbon fiber body) different materials bonded together with glue basically. They said one of the caps popped off like a bottle cap and the other one was still connected to the carbon fiber body.
I guarantee you that the "glue" was not the problem (remember the outside pressure is trying to squeeze things together, not "pop stuff off") - using carbon fiber for a pressure vessel under compression over many pressurization cycles with huge Delta P was.
This is a terribly sad, bad tragedy that could've been prevented had it been tested as it should've been.
But CEO Stockton Rush repeatedly claimed that industry standards of certification stifled innovation. He had passengers sign a notice that the sub was experimental.
Mr. Rush clearly rushed using the Titan, same as one of the financiers of the Titanic wanted to set a speed record despite the dangers of icebergs, believing the double hull would withstand any force, even tho it had never been tested.
James Cameron pointed out this similarity when it does seem the Titan imploded catastrophically as predicted from all the pressure, like the hull of the Titanic.
It had done okay on two previous dives despite serous malfunctions. But the effect of repeated stress on the titanium reinfoced carbon fiber hull wasn't tested .
Considering the pressure at 6,000 lbs per square inch, this was like cracking a hard boiled egg in one's hand.
May they all rest in peace despite Mr. Rush placing innovation and profits over safety.
Presumably, other entrepreneurs will now want make dives to see the remains of the Titan and the Titanic.
All Fives to the Titanic should be Stopped. There is NOTHING Left TO Learn . Leave the dead Rest in Peace.
I don't care how much money a Tourist has or any signed disclaimer. STOP THE TOURIST DIVES TO Titanic today. Enough.
Chill. Nobody cares.
What would have caused it? All the safety issues they ignored and the corners they cut, starting with the CEO's giant ego and arrogance!
One good thing is that if it is investigated they don't have to change the name from Oceangate.
good one
I thought that was sooo weird
Like Watergate?
The Ocean Gategate Scandal
Carbon fiber was popular in the construction of high performance bikes, but one expert I spoke with said that it can fail completely after some usage and with no observable warning or indications of eminent braking.
You shouldn't be able to do whatever you want, just because lots of money involved. Why was this not tested remotely first, numerous times?
Waste of lives 😢
A titanium door bolted to a composite hull. How many times was it checked for cracks.
The titanium "door" was bolted to a titanium ring, which was itself chemically bonded to the carbon fiber cylinder. Using carbon fiber for a pressure vessel under compression was the problem...
If you are super rich then just avoid sailing or diving near the Titanic point. That place has something against the super rich and doesn't like their intrusion. And it just gobbles them up and others accompanying them.
WOW..........What an amazing thought and and observasion
The hull imploded, and not because it wasn't classified. A couple of things it would be good to address:
(1) The use of carbon fiber to form the central tube of the hull. Carbon fiber is excellent for pressure vessels--when the pressure is inside, and the fiber is under tension. Under external pressure, the fiber is acting primarily as a substrate for the bonding agent.
(2) Gluing two titanium hemispheres onto the carbon fiber tube. Titanium has a modulus of elasticity and a thermal expansion coefficient 4-9 times greater than carbon fiber, depending on the direction of the weave. So every pressure/temperature cycle can weaken the joints, and the sub had been through 30-50 such cycles.
It was noted that the acrylic portal was only certified to 4000 feet. But the overall design seems to be questionable. And the lack of periodic inspections, any backup plans or redundant equipment make this whole tragedy look inevitable.
Great insights
I wonder, despite the assumed certain eventual fatigue failure of the structure, if a newer identical version of the sub could have successfully completed this mission, or would the forces have been too great regardless.
@@jrockofages5413 no, I think a newer identical version of the sub would work. I think the reason why this one failed is that it had been pressure/ temperature cycled too many times.
Carbon Fiber is definitely not a good idea for extreme repeated pressure and temperature changes. It definitely develops micro fractures every dive. And should be replaced every dive or just not used at all!
They should’ve used a proven material like heavy grade titanium or high strength steel for something like this. Even with very strong materials a small scratch in that material could cause an implosion at those depths. All the other submersibles that go to this depth replace anything glass or metal that has even the smallest scratch on the surface of that material. They don’t want to risk it and it has been shown in their studies a small scratch can in some cases cause a catastrophic event.
Didi you mean a small "Scratch" or "Crack"? I've heard of tiny fatigue cracks from eg. manufacturing defects, eventually resulting catastrophic failure, but not scratches!
@@TecraX2 I think at this pressure - barring other defects or imperfections developed from use or otherwise - it is likely that a titanium hull if it failed would fail along a scratch on the outer surface.
Realistically though, if it's rating easily exceeds the depth it is diving to than a scratch shouldn't be an issue. If it's right at the edge of its capabilities, that could very well be what causes catastrophic failure.
@@CheeryRhymes they probably opened a ballast and valve failed, when valve failed that equals the crack in the hull. I really dont understand why dive to titanic without a test.... they could have easily make a bot to drive it up an down, test it 600m+ deeper then titanc, if it survives it will surely go 600m less deeper without any isues. There is also very little space for any backup valves. considering this sub shuld also be bigger. and instead of a tank canister shape there should be x/+ profile pillars troughout the sub..
reinforcing any side posible, so the entier preasure force would split over entire submarine equaly, this hull could whitstand about 41000 psi of force maximal, meaning it is okay under 38000psi. Presure at titanix is 6000 psi. My hull would hold this many times over. BUUUUUUUUT!!!!!!!!! making a presure pump and a valve that shoots out water at 6000psi out of ballast tanks without blowing up... NOW THIS IS A CHALANGE!
I believe the sub had titanium as well. Both titanium and carrbon fiber are britle materials so in huge amounts of pressure they will instantly break
@@user-sb5jz6uv2j The Titan had been dived to the Titanic wreck sites a few times already (google it) prior to its first and last tourist dive. The carbon fiber hull developed micro cracks over time under pressure and temperature cycles.
And this is the reason on why we still don't have the technology or a machine that is capable enough to see the bottom of Jupiter.
The Pressure is insane!
Also the heat.
When the pressure is extreme enough to turn HYDROGEN into a metal, nothing humans could ever assemble has any chance.
@@NullHandnot yet but in a few decades we could
To be fair, there is a world of difference between a manned submersible and an unmanned submersible.
If you don't have 'space' aka air inside the object than its virtually immune to pressure issues - I mean in regards to Earth's oceans.
That said, the pressures inside a gas giant or a ludicrously deep body of water on another planet are an entirely different... leagues.
@@millennialpoes5674 doubtful...
We know basically all the elements that are physically possible and unless there is some amazing combination of elements that creates some workable but extremely amazing material than it's just not possible.
@@CheeryRhymes once we learn how to manufacture using carbon nano tubes in a practical sense, it will be a game changer. Think what 3d printing will evolve into 30 years from now.
The sub imploding at that depth would be like having the weight of a Rolls Royce compressed into a column on every square inch of your body.
Actually more like the weight of the Empire State Building on every inch of you body.
To dumb it down...
You become mom's spaghetti on your bloody sweater already
it’s like the legends in Egypt when the tombs where disturbed people that entered got sick some even died this is a horrible tragedy
Who would’ve thought Titanic will take 5 more lives even after 111 years?
It's said other subs are spherical, making it easier to equalize pressure on the whole vehicle & made of steel 10 inches thick. This carbon fiber was only 5 inches. Carbon fiber is made in layers to achieve the desired thickness. This adhesive used was not really compatible with salt water & so thereby affected the integrity of the construction. This, plus the fact that when joining 2 different materials there's always the risk of a seal failure. This whole thing sounds like it may have been doomed from the start. GOD BLESS them & their families. 🙏😪
Carbon fiber is usually bound with an oven cured epoxy.
Salt water would not affect that by corrosion. It is the preferred marine adhesive everywhere.
But Carbon fiber composites are only superior in TENSILE strength.
Unfortunately what a submersible pressure hull receives is COMPRESSIVE loads.
Carbon fiber is also brittle.
They would have been better off making the whole pressure hull titanium.
Or even stainless.
All of this would've been tested except the license for international waters doesn't require it.
My carbon fibre race bike has taken a few hits that can only be repaired so much. Any major impact will force me to trash it and make me wish I'd stayed with Italian steel.
Looks to me like god already gave them a big fat finger lol.
carbon fiber & epoxy jeez...wonder if this is all staged?....Zero footage of them before it departed on the 12,500ft dive...weird

Did they conduct detailed safety risk assessment and actions prior to start up of the trip..?
One thing I’ve wondered about is that if the water pressure is so heavy at that depth then why hasn’t the Titanic wreck been completely flattened? Especially after over 100 years of corrosion.
In view of the multiple dives to the extreme depths by Titan in the past , it is technically obvious that there would be structural changes which were not detected by the vague uncertifiable tests which the company aparently relied on. Hence the catastrophic destruction on this dive. In fact if the structural design is analysed using AI which is now a easily usable tech the possibly weak points of the sub could be easily evaluated which could also be helpful in analysing the parts of debries which are purportedly being recovered .

The Titanic was a tragedy. It was a horrendous tragedy. Many lives were lost 😞 I strongly believe is time to let the Titanic RIP. It was that same mentality; lack of safety and lack of critical thinking that caused the Titanic to sink. Mother nature is one force you don't mess with. There is a reason of why studies take place in science 🧬, engineering and physics. My sincere condolences 💐 to the victims of the Titanic and the victims of the Titan.
Carbon fiber is used in pressure vessels because the high pressure is on the inside, forcing the wall into uniform tension, and thus producing a stable system. But in this case, very high pressures exist on the outside of the wall. As the vessel descends, the external forces increase while the internal pressure remains the same (1 Atm). Given 1 Atm on the inside and maybe near 400 Atm on the outside, the system begins to resemble a vacuum system. So, it begins to approach an unstable system. In addition, carbon fibers are not uniform or perfect materials. A very small impact on the surface of an unstable system - or maybe a flaw or crack inside the wall - might cause cracks to grow. Cracks grow under pressure. And at these intense pressures (approximately 400 Atm), I suspect that even a minor crack in materials such as carbon fiber would quickly lengthen until the wall shattered in an instant.
They couldn't have chosen a more unforgiving material for a deep submersible hull.
So many peotic ironies in this disaster, it's mind-boggling. Titanic sunk mostly due to the Captain's arrogance, and now the sub made to see it, named "Titan" implodes and sinks mostly due to the Captain's arrogance. Both Captains going down with their ship, not to mention the that CEO's wife is the great great granddaguther of a couple that also died on the Titanic. Wouldn't be surprised of a movie also being made of this.
I wonder if some pressure warnings went off before the implosion, and they knew it was coming before it happened
According to James Cameron, they probably did. One can only imagine the panic that took over the crew when they realized that they were going to be crushed like a truck-stumped burrito.

Being carbon fibre it seems extremely unlikely they had ANY warning. I'll be amazed if it turns out they had even a second of warning.
That stuff fails super suddenly when it reaches its braking point.
Lack of inspections after the alleged several trips to the wreck last year.
Subs are similar to aircraft in that the structure expands and contracts in normal use.
It probably developed cracks and just like an airplane with cracks, it broke during use.
The unfortunate thing is that this casualty is going to result in someone coming up with an idea on how to do something similar that can actually work on a very consistent and safe basis!
So very sad but imploding would've been the most humane thing. It's instant and painless. Rip
How about no certification! , No inspections! , Cutting corners and doing sub test in countries with no regulations or certifications
I’m certainly no expert on this but surely there has to be a limited amount of times that a little subs pressure chamber can take the stress of going down there before the pressure involved weakens it structurally just enough to completely fail?
The thumbnail to this video is a photo taken in 2004 that shows the remains of a coat and a shoe from the Titanic.
It is inappropriate to combine risky science and tourism business
Damn straight! And can we please stop calling them explorers.
Irresponsible, not just inappropriate.
“Stockton Rush emphasized safety.”
Right. Nothing says safety like the window being made from material only rated for 1300m when the sub is supposed to go to 4000m.
Nothing says safety like ignoring the warnings of a professional ex-military submariner safety inspector because he was a '50 year-old white male'. Nothing says safety like hiring a crew based on skin color and not things like...ohh...I don't know...EXPERIENCE AND QUALIFICATIONS! Wokeness kills and unfortunately a bunch of innocent lives had to be lost because of it.
Stockton Rush was mentally unfit
Carbon fiber may be strong but it’s not dense it was bound to fail at those pressures, you need density so it doesn’t flex weakening the structure.
Density has effall to do with it.
Since the submersible was experimental, I guess you could say the experiment failed.
😢 This whole situation scares me.. I really hate this Happened 😮💨
It was the Pressure.
I think they need to be able to withstand 10X the pressure at 5000 feet.
Even after charging premium for each seat , they still couldn't save their customers and their own CEO just because they didn't want to pay for proper certification.
I hope this company shuts down
Of course they will.
The CEO is dead and nobody will ever get in one of their subs.
We see beautiful rock formations in the desert due to the rocks expanding and contracting due to heat and cold. It appears that the sub also was exposed to these extremes and eventually failed. Hopefully this tragedy will lead to better inspections and designs in the future.
What do beautiful rock formations have to do with this? Because they expand and contract due to temperature? When we're talking about pressure on a submersible.
Ironic oceangate president Ignored safety just like the Titanic captain did. Wow
Thus, history repeats itself. Crazy. And they say karma isn't real. Explain this.......
Human error perhaps?
CArbon fibre body with a titanium nose, my money is on those two materials reacting differently to the pressure causing fatigue
And causing an imbalance to the structure of the sub which resulted in its implosion. Could be a likely scenario.
A tragedy that could have been avoided
They signed a Waiver that warned that dying was possible so they knew the risks and still went on board with it.
I guess they knew something horrible happened that's why they waited more than 7 hours to alert the cost guard because they could not believe it
OceanGate: exists
Titanic: I'm about to take a revenge.
Umm how about because it was made from hobby store parts, hadn't passed any regulation checks, ignored safety warnings brought up by experts, laughed at the danger risks, used a $40 xbox controller to drive it, had a viewing hole that was only designed to go down to 1300 metres not 3800
That controller was probably better than anything they or even large companies could make.
But yeh I otherwise agree.
@@CheeryRhymes the controller was WIRELESS . and no you can get controllers even for $200 that are much more durable than whatever hobby store part they chose
@@Steezy93 I'm talking about the controller. Not how it was connected.
Of course wireless was a terrible idea.
Sea serpents, aliens, megalodon, lost souls from the Titanic. The list goes on lmao
And now 5 more billionaires!
God
How about simple realistic cause such as carbon fibre glue can only last 3 deep sea dives
Weirdo laughing about 5 people dying. Creepy guy you are.
I wonder if the ceo really got into exploring the titanic because his wifes great-great grandparents were among those who parished in the titanic. Either way if that is the case he should have taken himself, not dragging along innocent people to their deaths, all for money & a thrill. Rip to the ones that lost their lives at the hands of an inexperienced stubborn man. Rip to him as well but what he did is unforgivable. Sorry to his wife, that is 3 people she lost at the titanic site.
Why are uncertified things allowed to commercially operate?
It was built crappy and not certified to the depths needed. Pretty easy to figure out.
Just even a small bump that causes in indifferentail shake, ripple throughout the small capsule instantly become structurally instable and the pressure takes over. Everything has an opposite or equal reaction and since the ocean has way more power it won very easily. A small bump at sea level does nothing but when you have thousands of pounds on you makes a huge difference. Example get stuck in a tight spot in a cave or under a car. Once you let your chest give in there is no go back cause the environment around you will make sure your chest is no longer expanding.
Bumps have nothing to do with this. Jesus.🤦♂️🤦♂️🤦♂️🤦♂️
@@spanqueluv9er not sure you understand what Iam saying. Any bump on the haul or ripple they made its way though the structure of the submersible could cause a larger reaction. Push a needle into a full can of pop and see how easily it peirces the can compared to and empty can with no pressure.
I think I understand what you're saying but it was nonsensical and your example is ridiculously unconnected.
I get your point. Any micro defect is magnified under such conditions.
@@jrockofages5413 sorry Iam not the sharpest tool in the shed but you seem very bright understand where I am coming from.
Aye mateys, the sea never gives up her dead...
Interesting that the video shows one of Titanic's boilers laying on the bottom and wondering how long before someone posts they see this as the vessel in question.
“I highly value life so I wouldn’t have gone in that” is a nice way of saying ‘I’d rather not die.’
What could have caused this? Buying a plastic submarine at an estate sale and trying to turn it into a half baked startup company.
carbon fiber has a tendency to crack over time from fatigue, exposure to UV light and the elements. it occurs in carbon fiber bike frames and even composite wings used in large commercial passenger aircraft. more than likely the failure is from the carbon fiber hull. i've also read the viewport was only rated for 1300 meters whereas the titanic depth was about 3800 meters which is well over the viewport rating.
@trumpsucks2290 Carbon fiber diesn’t fuqqing crack, it delaminates ffs.🤦♂️
The jackass CEO refused to pay for a viewport rated to 4000m. He took all sorts of really silly risks with this thing. It's too bad that he cannot be held to account, except via karma.
I mean for as stupid and reckless as he was we can’t deny he had enough belief in his own sub to go down with it himself, a horribly ironic parallel to what happened with the captain on the titanic. The real stupidity I can’t fathom is charging 1/4 of a million a head so that is a million dollars per dive and he couldn’t even invest in a viewport that would withstand the pressure of the titanic location? That to me is where gross negligence really comes into play.
Ya the viewport is the point of interest for me.
And yet it has made multiple dives. Stick to what you know, which is very little and leave the subs to the experts.
One correction - 'this time something went wrong'. No. Every time that Titan went down, there were issues to deal with. Alarming issues. And these were ignored. There are other subs built with help from the Navy that have gone down repeatedly to 7 miles depth and had zero issues with the build. This was janky engineering from the start.
David Lockridge, a UK ex-Navy engineer was Director for Ocean Gate. He brought up the fact that you cannot use carbon fiber as material, laminated on top of that!. He stated that the acrylic viewing window was rated for 4,250 ft but they went down to 13,200 ft, that the sub had zero certification testing, and more. And he was fired for speaking up. It reminds me of the NASA engineer who spoke up and said there was a problem with the Challenger launch, and they launched anyway, and it blew up while still exiting Earth's atmosphere. Catastrophic failure of the Challenger due to a distorted O ring. It only takes a tiny flaw.
Stockton Rush was a reckless man who took risks with his life constantly. He had no business to risk other lives. He hid this fact about the acrylic window. He hid the fact that that rinky dink build had issues on EVERY dive and was NOT CERTIFIED. I think his passengers got a false sense of security because Rush was on the vessel himself, so they thought it must be safe. I initially thought that all these subs were experimental and that this was the sacrifice you made in the name of science. But not so! There are ten other subs that can dive to 7 miles depth (this dive was 2.5 miles) and no lives have been lost and nothing failed on the vessels. Plenty of other things can go wrong like being snagged on debris, strong ocean currents that slam you into debris, and more, but no one had to worry about malfunction of the sub itself. In the case of the Titan, it was a stream of malfunctions. By sheer dumb luck Rush did not implode earlier. Always trust the engineer, and use proven methods that work!
Rest in peace
One thing that's yet to be explained is the repeated and evenly timed banging sounds that were detected, when the submarine occupants were already long dead.
It was Davie Jones banging his girlfriend
Ikr
This was misreported by one news site and quickly spread by others. It wasn't true. They heard noises but unidentifiable, likely oceanic and not at regular intervals.
@@bethaneaniec1833 Do you have a source for this?
@@bethaneaniec1833navy heard the implosion tho
I want to see a simulation of what the human body looks like when it implodes that deep in the ocean.
You dont need simulator for that. Just imagine what happens when 60 elephants stand on a man simultaneously.
myth busters already did an episode of what happens to a human body under extreme deep sea pressure. every inch of you is crushed internally then you liquify through every opening of your body. in this case the sub killed them before the pressure did.
why?
As an example based on the PSI they experienced, it’s the equivalent of trying pressing a six foot man down to the height of ant in 1/100th of a second. I do believe they got an alert, and were trying ascend right before it happened.
@@perry92964 Because I'm a curious guy.
I heard that the tapping sounds were morse code for 'we don't want to die like this, can you help us?'... to which the response was 'no, but we can end it quicker'
The only one I feel sorry for is the kid who didn’t wanna go but did cause his father wanted him to, other than that, just billionaire incompetence, nothing to feel sorry for.
Under pressure, pressing down on me, pressing down on you!
Well I heard they used cheap materials to build the sub which is something you don’t want to do, you want to use the high quality materials to build a sub especially if you want to do very deep dives in insane levels of pressure, I am not trying to be harsh, it is just when you build a submarine you got to think smartly not cheaply, you’d want the best and most durable materials imaginable when building your submarine.
That submarine looked very cheaply made and I am sorry to say it but it looks like it was poorly made.
Why get a certificate when operating it in international waters? To get on it, you had to sign a waiver, they can not blame anyone else but themselves. They took their lives on their own hands when entering. My .02 cents worth.
Waivers are essentially worthless FYI.
My thoughts are with the original lost souls, on a dark sinking vessel in the middle of the ocean, Men, Women children and babies. All loosing there lives unable to save themselves!! 💔 RIP to all at the Titanic site
They used carbon fibre for the sub. The pressure from the amount of dives it took must of been too much for it to take
The Occams Razor principle works here. The weakest part of the craft was the nose end. It was made with plexiglass with 8 bolts, which could only be opened from the outside. This was the weakest part of the craft. The glass took the pressure from outside the craft but the BOLTS could not keep the pressure from popping the bolts off. The craft was NOT tested to the depth it would go to.
I know nothing about subs but this seems to be the only reason, to me. RIP.
Thank you., Than why offer your insight?.....THUMBS DOWN......NO LIKES.......HARD PASS......EXPIRED.......GTFOH
Why didn't you tell them that before they left for their voyage?
To be fair... The bolts at that point are probably under no tension because the pressure would've pushed the glass against the vessel.
I just think the glass simply broke from the pressure - Just like leaning on a glass door
Edit: can also just be a bend in the carbon fiber, too. Strong yes, but brittle.
@@TheShamarskimy question is why did the glass not break the first 3 times ? As it went down there Before
@@therealman2016 If it was the glass, please be advised that materials can sustain forces which damage them without causing them to fail completely. Just as metal can fatigue, composites can delaminate, and acrylics/glasses can fail over time due to cumulative stresses.
This is crushing news
Are there any actual videos of an underseas implosion?
the passengers didn't experience long drawn out suffering, but it wasn't exactly instantaneous either. after 100 minutes of peace and tranquility descending to the ocean floor, they were suddenly met with a moment of 'shock n awe' at/near the wreckage site, when the audible indicator sounded off indicating catastrophic loss in pressure due to rupture of the hull -moments before the occupants and vessel were crushed like a tin can leaving only pieces of debris to spread along the atlantic's bottom
Implosion time till death, 1/20th of a second. Yes. Instant soup.
So did they even reach the Titanic? Or did it implode halfway and the debris of the sub sank to the bed of the Titanic.
It all started at about the hour point. Once they descended to that deep depth you get the feeling in your stomach that you get when you drive over a dip in the road really fast. Or when an elevator takes off fast from the first floor. But at that depth the feeling is exacerbated by 20 times and it makes the person have a sudden urge to use the toilet.. Unfortunately with 5 people on board with the sudden unstoppable urge to use the only toilet on board the methane would have built up to the point of combustion. Forty five minutes later while travelling through a cluster of bioluminescent creatures somebody grabbed the cheap glow handle light purchased for $20 at Cabelas that caused a short in the cheap chinese electronics and started a single spark then an ignition of all the built up methane a few seconds before the implosion commenced.
@@MostHated_10think they said they were five hundred feet or something from it
@@westernrider100 Yes I read 1300 m too. That's so obviously too shallow that I wonder if 1300 means something else or it wasn't 1300?
The tiniest flaw would've been enough to cause the implosion.
That seemed to be missed by The CEO of the company.
