Onlookers caught glimpses of the Titan submersible wreckage as its crews brought its remains ashore. These provide clues to what may have happened while a formal investigation is underway. Though it's difficult to know for sure, an expert said the carbon-fiber hull likely failed first.
Photos of the Titan submersible wreckage support the theory that the vessel's carbon-fiber hull may have led to its catastrophic implosion, an expert told Insider.
The US Coast Guard brought debris from the Titan submersible ashore this week, giving onlookers a brief, imperfect glimpse as it was taken away for analysis. ...
Though it is impossible to reach a definitive conclusion from these pictures alone, he said the most likely scenario was that the carbon-fiber hull gave way under the enormous pressure of the ocean depths.

Captain Smith made no effort to get to a lifeboat and went down with the Titanic. That was what he was supposed to do, and that way he didn't need to explain things to a board of inquiry or whatever.
The other parts came up more or less intact, but they didn’t recover any carbon fiber.
Being someone who is something of a Titanic buff (since I was a kid), your comment about Captain Smith makes me think of the mystery involving the ship’s log. I recall reading discussion about that subject some years back in that the ship’s logbook supposedly should have been given to someone like Lowe or Boxhall or any of the other personnel who survived the disaster and that would have been an important item for the inquiries both in the United States and Britain. The logbook was never recovered but I remember watching an interview with someone who explored the wreck area looking for artifacts and that that would have been the Holy Grail for him and the others (letters and papers were recovered and restored through modern freeze drying technique).
F@@@ you, “Business” “Insider”. It isn’t a theory. There are no other possibilities.
Shows to me the resin had microscopic air in it. Repeated compressions during dives would essentially turn the resin into powder, held together with carbon fibers. They might find some carbon fibers around the wreck site but imo the resin is mostly dust dissolved in the water. But hey, at least he was the first.
People warned him?
OMG he should’ve abandoned ship immediately if not sooner.
Ironically, multiple pilots warned the FAA about the Boeing Max to no avail.
Ridiculous, they’re dead and not here to defend themselves against former disgruntled employees and other past posters
“F@@@ you, “Business” “Insider”. It isn’t a theory. There are no other possibilities.”
Having published over fifty articles, I can attest that editors are terrified of the author making definitive statements. The author can quote someone else who makes a definitive statement but can’t themselves make one. That’s because editors “know” all reporters are idiots and are trying to avoid any liability. It’s so engrained it’s second nature. Even when I was the subject matter expert, having worked in the industry and having an engineering degree, I either had to find someone else to make the statement or the editor would reword it in some mealymouthed way.
The existing submursibles are made of quality steel and spherical shaped, and can only take 2 people, so they could only take 1 tourist at a time.
It operated in international waters, so it was subject to no regulation.
If there were a multitude, or even a smattering of other valid possibilities, one would have to concede that all those who warned this psycho about the failure of the carbon fiber were in fact, clairvoyant.
I would put this debacle more in the territory of, fait accompli,or "foregone conclusion," than, I would, "theory."
I’m not an engineer, but the whole idea of using carbon fiber doesn’t make any sense to me.
I thought carbon fiber’s strength is in tension.
That works great on a pressure vessel when the pressure is on the inside and the structure is in tension trying to contain the expanding gas.
But this was a pressure vessel with the pressure on the outside. The carbon fiber would be in compression - so most of the load would be carried by the resin.
Carbon fiber propane tank would seem to make a lot of sense. Carbon fiber submarine - not so much.
Titanium is also subject to fatigue creep.
It was an issue on the Russian titanium subs.
Bingo!
Like, for one example, the view port was only rated to 4,000 ft. Rush himself reported that it deflected inches on the test dives.
The public saw what the public was allowed to see.
He ended up going before a different board of inquiry.
“There are no other possibilities.”
Really?
1. The plexiglass viewport in the titanium dome was rated for ONE THIRD the depth they were going to. It could have failed.
2. The titanium dome was GLUED to the carbon fiber hull. The glue line could have failed due to differential thermal expansion.
I’m sure there are others, too.
It was no accident. The implosion was caused by narcissism.
Been working with the stuff for near 20 years now. You are correct. It is not suitable for compression loads. The example I give is “try pushing one end of a rope with the other end.” It is great for pressure loads (think aircraft) but it is not used in compression loads. At least I have never seen it used in compression loads.
Yeah, at this point I'll be very surprised if any of them are found dog-paddling in the Atlantic.
