Why are people assuming this? How about a leak that fills the sub with water? Is a leak impossible to keep stable at those depths?
A leak at 400 atmospheres doesn't stay a leak.
If the sub imploded shortly after reaching the titanic, how exactly did the people on board die? Was it an instant pressurized death? Do they drown or something?
I am wondering the same. Everyone is talking about the rapid implosion of the sub, but can we assume that the bodies just got instantly crushed into nothing?
If it was structurally compromised, the implosion would be so fast, a combustion event a la what happens in diesel engines would have occurred.
There would be no bodies. There would only be shreds of pressure hull.
The titanium hemispheres may have maintained their shape. There is a slight chance it may have been a pinhole leak, and someone had a second to go "Uh..." before the rest of the structure started giving way.
It is clear that even these "strain gauges and microphones" to detect compromise of the structure were useless, or that the issure ultimately rested on the window in the front.
The main point to keep in mind is that short of finding the two hemispheres in the next day or so, we'll likely not know the full details with regard to the course of events of the unmaking of the vehicle.
The Sea has claimed them, and she is wont to give up her dead. Hubris, met by the cold hard edge of reality, has proven to be an insufficient aegis once again.
May they rest in peace.
Well, this explains a lot... they didn't have a window rated for the right depth and weren't really testing whether the hull was de-laminating according to the whistleblower, so we have a few guesses as to why the sub would just implode. The lack of contact would be because nobody was alive to contact, which is honestly better, at least they had a quick death instead of slow suffocation. And the banging noises are pr…
In the press-conference they said both end bells were found separately - no mention of whether the window was still intact. It'll be interesting to see the failure analysis. [Edit] Link to video with a description of the major debris found: https://youtu.be/A0xJ220Fod4?t=263 "the front end-bell of the pressure hull - that was the first indication that there was a catastrophic event" "the aft end-bell which basically.…
If it was the Plexiglas that failed (or other part of the end bell assembly), I'd expect the pressure to quickly equalise though the failure point and the carbon fibre shell to remain relatively intact and hold those end bells together.
Though, I'm not an engineer. Maybe the rapid change in loading could result in the carbon fibre shattering.
wonder if the window imploded or the whole thing just crushed like a soda can experiment
It doesn't break like soda can, it breaks like eggshells or hard plastic. It would probably look like something exploded on side of it, when any small hole/crack started it would just isntantly make rest of it rip till the pressure equalizes
"The Titan began its descent Sunday to explore the wreckage of the Titanic, located about 13,000 feet below sea level in the North Atlantic Ocean, with an estimated 96 hours of life support. The expedition was billed as “a chance to step outside of everyday life and discover something truly extraordinary” and cost each participant $250,000, an archived version of OceanGate’s website shows. "However, the cramped vesse…
> The ocean is very, very deep. The Titanic is "relatively" shallow, only 3800 feet below sea level It's 3800 meters , 13000 feet as you wrote in the first paragraph. Nothing shallow about 3800m deep, that's abyssal plains level, it's basically the bottom of the "normal" ocean (the abnormal ocean being the hadal zone of the trenches). It's a land of no light, little to no oxygen, and literally freezing cold.

Their bodies are also pressurized at 1 atms, after being exposed to 400 atms they instantly died. My guess is that they were effectively vaporized/liquified. Much better way to go then suffocate in darkness.

Regarding the quality issues of the submarine "Mechanic on ‘record-setting’ Titan dive dismisses criticism from ‘armchair experts’" https://news.yahoo.com/mechanic-record-setting-titan-dive-19...
Though insinuating all critics were "armchair experts" is pretty disingenuous. There were plenty of real experts raising serious safety concerns, including the guy who got fired for not approving manned test dives because of them. If there was a strong consenus among real experts that this thing was safe, then they would have had no trouble getting the relevant safety certifications.
Everyone, everywhere just parroting and re-parroting the same comments, attitude, pretending to understand the engineering with snippets from comments they’ve read, reactive talking points, etc…
Very strange.
