Titan submersible wreckage recovered from water after fatal implosion

Who pays for all of this 'wreckage recovery'?

"Some things are apparent. Where government moves in, community retreats, civil society disintegrates and our ability to control our own destiny atrophies. The result is: families under siege; war in the streets; unapologetic expropriation of property; the precipitous decline of the rule of law; the rapid rise of corruption; the loss of civility and the triumph of deceit. The result is a debased, debauched culture which finds moral depravity entertaining and virtue contemptible."
-- Justice Janice Rogers Brown

Per the Sub Brief video, there was a data acoustic modem that transmitted telemetry back to the ship above so cocksucker Rush could enjoy his sub ride in peace.

My thought process is the whole thing is under X pressure. If the acrylic viewport shatters, at that moment, the whole thing is still under X pressure. I’m guessing, but I don’t believe the external pressure on any other part rises which is why I’m guessing the carbon fiber tube wouldn’t collapse. What I think happens next is the rebound from the implosion pops the end caps off, but because the tube is way stronger in tension, it survives the rebound of the implosion.

Just a WAG on my part.

Not even close. Carbon fiber is not a flexible material. It does not bend, it shatters. This is what happens in an implosion from the opposite side:

Even if this disaster was made from steel, there is an immediate pressure imbalance leading to what happens in the video, except the carbon fiber would shatter into billions of pieces leaving the top and bottom metal caps.

The Acrylic Lobby

I know that makes no sense, but since it now seems that every post in this thread must contain the word 'acrylic' I figured 'What the heck, why not?'

I would guess that if the viewport was the point of failure, the water would have rushed in from there preserving the carbon fiber tube.

I'm having trouble understanding how else it would happen also. The single atmosphere of pressure inside is negligible against the hundreds of atm externally, and isn't doing much of anything as far as resisting collapse. If the viewport breaches, you suddenly have all that pressure outside free to get inside. That means the pressure will actually equalize, quickly and violently. This would take stress off the hull, not collapse it.

The next step is detonation of the now compressed contents followed by auto-ignition, which would be an explosion, not an implosion.

I still lean toward simple collapse of the hull causing implosion, but this other way is still a technical possibility.

EDITED to add I avoided using the term "acrylic". Except now I did.

Either one would led to the other. Failure of the window leads to catastrophic implosion where the carbon fiber hull shatters. Failure of the carbon fiber hull leads to catastrophic implosion where the hull shatters and blows out the window.

Unfortunately, it looks like the viewport is not intact, and we don't know how it failed. Obviously if it were in one piece we could automatically rule it out as the initiating failure. I wonder if we'll ever know for sure.

The implosion happens *much* faster the speed of the water ingress through the (potentially) compromised acrylic window. Literally no time to equalize.

What are you showing us, trapper? Context, please. Is that a stock image? An image taken today? You're not new at this, come on.

~~This is probably all academic with the viewport found intact~~, but why would implosion happen at all? That single atmosphere of pressure inside the vessel wasn't doing much in the first place. At the moment the port breaches, pressure begins to increase and equalize, taking more and more stress off the hull.

Actually Para makes a good point. Is there a source validating that pic as the Titan's recovered viewport? There's already AI-generated fake recovery pics going viral.

I’m so sorry, my daughter interrupted me mid-post and my son said the grill temp was down on the ribs I’ve been cooking for 6 hours.

It’s a before shot as in before it was installed. The picture was from OceanGate’s website, but the site seems to be down.

Presumed human remains found per Canadian Coast Guard

Human remains have been found in the wreckage of the Titan submersible on Wednesday, the Coast Guard announced.

Several identifiable parts of the ship were lifted ashore on Wednesday afternoon, including the sub's nose and a large panel which appears to be from its tail end.

Amid those recovered pieces, the Messenger reports, Coast Guard officials discovered human remains, which will now be transported aboard a ship to a port in the United States where they will undergo testing and analysis.

Yeah but, if the integrity of the hull was broken, those extreme pressures may have been so high that even it was the ACRYLIC porthole, that semi-large hole may not have been large enough to allow the sea to enter fast enough, "equalizing" pressure and allowing the tube to survive.

Or maybe, it was the hull itself that failed to start with. Carbon fiber isn't like metal and won't crumple but will break or shatter.
