Can’t think of any environment where hubris was less appropriate than in this area (sufficient testing to protect human life).

Wow - the photos of the large pieces and bags of small debris. I wasn’t expecting them to bring it all up so quickly.
“Pelagic Research Services, a company with offices in Massachusetts and New York that owns the ROV, said in a statement on Wednesday that it has completed offshore operations.”
But they are “still on mission” with the investigation.

I suspect they had done this so quickly because the ROV was already deployed in that area. I read that they needed a heavier piece of salvage equipment to lift the objects to the surface because the ROV was not designed for lifting large objects, and the equipment was on the way as soon as the debris were discovered.

I’m “glad” that they felt no pain. What I wonder is, was the sub making odd/alarming noises, which they might have noticed? If so, how long would they have been on alert for trouble?
Would they have been able to contact anyone about their concerns?

There was some chatter that the Titan was releasing ballast to rise back to the surface, indicating that they MAY have heard something. My understanding was that Titan had an acoustical monitoring system to detect any issues with its hull. However, several experts commented that this would only give the Titan an alert with very little advanced notice of something catastrophic happening.
Given the very limited/sometimes non-existent communications with its “mother ship,” the Polar Prince, it’s hard to know.

From my conversations with engineers, carbon fiber composites fail instantly. People who race composite bikes know that. There might be no correlation between noises and the remaining time to failure, so who knows what those sensors were reporting. If you are 3/4 into your Titanic dive, you need more than a few seconds warning to get back to safe depths. Plus, composites are not like metal: if the hull was about too delaminate, the process is irreversible and can’t be stopped. That’s what I was told.

From CNN:
“ CNN —
[Breaking news, published at 6:14 p.m. ET]
The US Coast Guard has recovered “presumed human remains” from the seafloor in the area of the Titan submersible’s debris field and will conduct a formal analysis, the military branch said Wednesday.”
May they all rest in peace.

A professor makes his predictions of what the investigation of the incident would find.
And NTSB says the official investigation will release the findings in 1-2 years.
