Titanic tourist sub goes missing sparking search

So we've flown 180 million miles away from Earth, intercepted an astroid, fired two rockets into it, collected the debris and brought it back to Earth, but we cannot even pick **** up from the ocean floor at 2km depth?

4km. Not 2k. We know more about our solar system than the oceans. Which makes sense.
Not sure if serious or living under a rock.

Yes.
 
that's just great, they knew from the start it likely imploded and everyone's dead

but we still got dragged onto a media hype tour for days, ggwp

Movie director and undersea explorer James Cameron says pretty much that:
He said he was on a ship on Sunday when the sub went missing, and did not hear about it until Monday.

When he learned that the sub had lost both its navigation and communication at the same time, he said he immediately suspected a disaster.
Cameron told BBC News the past week has "felt like a prolonged and nightmarish charade where people are running around talking about banging noises and talking about oxygen and all this other stuff".

"I knew that sub was sitting exactly underneath its last known depth and position. That's exactly where they found it," he continued.
 
I see folks are already posting the info from the US navy. Certainly points to the event happening at the point of last contact. I wonder how do they were at the time as it was still on the descent.
 
Short video by Juan Browne about the composite construction of pressure vessels. Some of the comments and replies are informative, given the deficiencies of the process:

TL;DW

Carbon fiber is stronger under tension than compression. What works to contain a high pressure gas inside a cylinder, doesn't work so well to contain external pressure underwater.

Composite materials have a finite lifetime of repeated flexing. In this case literally...

Sadly, that is big business at the expense of life. Companies/ people had to make money out of the "search and rescue" operation that was prolonged.
 
US Navy detected Titan sub's catastrophic implosion before rescue attempt began

As multiple ships scoured the North Atlantic this week for the missing submersible headed to the Titanic wreck site, the US Navy had already detected an implosion on Sunday at the site where the vessel lost communications.

The information, which was not definitive, was immediately shared with the US Coast Guard, and a decision was made to continue the mission as a search and rescue to “make every effort to save the lives on board,” according to a senior Navy official, who spoke under the condition of anonymity.
