The technical challenges of the rescue efforts fascinate me.

What about the financial ones shouldn't this come out of their company coffers? Sorry not sorry

If there was even a pin hole- at 5800PSI, it would fill and explode in less than one second.

Yes it would fill quickly, but would it implode?

If it just filled up that would rapidly kill the occupants from either the pressure or drowning but I think it wouldn't make much noise.

OTOH, if the pinhole led to a crackup that would make noise.

Apparently I was wrong:

US Coast Guard says they found the tail cone 1,600 feet away from the rest of the sub.

That is clearly a catastrphic implosion. How did the control ship not hear it?

14000 or so feet down? Over in milliseconds?

no chance it would be heard. Imagine taking a small, loose dirt ball in you hand, the size of a marble. Now crush it between your forefinger and thumb, until it turns to dust. How much noise does that make?

If the surface ship had any kind of passive sonar it would almost certainly be heard. I don't know what would lead to such a catastrophic hull failure of course, maybe something at a seam of the port window. If a leak started they'd loose buoyancy quickly and sink.

I don’t think you understand. And this is not coming from me. This is coming from the engineers who were talking about the situation.

between 5500 and 6000PSI at that depth. A leak?
A leak the size of a needle head-at that PSI- would only last around 500 milliseconds- it would not “ fill the sub”. It would instantly crush the vehicle and anything in it.

I'm with @Cincydawg on this:

The surface ship should have been equipped with passive sonar and they *SHOULD* have heard the implosion.

Yes it is over in milliseconds but that makes it more not less audible. That crushing makes noise and sound travels MUCH further in water than air. I *THINK* they should have heard it.

I don't know why a tiny leak would instantly crush the vehicle. I'd hate to get in its way. I think it could have a tiny leak that didn't crush the hull at least initially. Do we know at what depth they would have been when contact was lost?

There doesn't appear to be a connection between the banging noises picked up by sonar earlier this week and where the debris from the Titan vessel was found on the sea floor, a US Coast Guard official said.

Quote

"Again, this was a catastrophic implosion of the vessel, which would have generated a significant broadband sound down there that the sonar buoys would have picked up," Rear Adm. John Mauger, the commander of the First Coast Guard District said, while also noting that he would check again with experts on any possible connection.

Well- they didn’t. So, there is that.
I have now heard 3 different ( alleged) experts say that it happened so fast( once the vessel was compromised) that the people never even knew, and they were not surprised nobody on the surface had any idea.

I would guess the sound was picked up by our SOSUS underwater listening devices. The left from the top dot and headed south to the Titanic site lower yellow dot.

Ok. You would guess. But they are saying it wasn’t.

It didn't blow at full depth. It blew when the mothership lost contact. Hence the scattering of the debris.

Remember, as we know, at those pressures, if a molecule of water gets in, it's over instantly," Pogue told CNN's Jake Tapper on Thursday. "I know it's no great comfort to the families and the spouses, but they did die instantaneously. They were not even aware that anything was wrong."
