The banging was likely the sound of hundreds of news organizations flogging this story to get more clicks.

Nope; banging was officially announced in the press conference of the search and rescue team. Though they could not confirm that it was really the sub (they probably thought that it was, but they can't officially say it).

I think your sarcasm detector has developed a fault.

I agree but not at 250k a head. It should be safer, but everything is done to a price point and I'm sure those on board recognised the risk of such an expedition.

I seriously doubt the victims knew how risky this trip was, even though they signed the waivers. Why would you bring along your 19-year-old son if you thought the chance of death was 1/100 or even 1/1000. The CEO, who obviously overestimated the safety of his cost-cutting design, had raised $20M in venture capital, it's not as if he had a death wish either.

Optimist.

If it did implode in multiple pieces it means the experts were right; many said that carbon fiber was a poor choice because while it's light, it breaks like glass, contrary to steel which tends to "open" slowly.

It's a shame they openly did not hire SMEs.

Would the implosion have been loud enough? I mean the thing was a tiny 7x3m cylinder located 700Km from the nearest coast...

How do submarines commonly fail? Is the assumption of a violent implosion warranted? I would think another failure mode could be water rushing in without the overall structure catastrophically failing, which would actually relieve pressure on the structure as it happened and be much less energetic.

But would make the inside sort of uncomfortable, what with PV=nRT

Why is it more likely that it immediately imploded rather than after a few days? The latter is more probable to me as it has never been tested under water for more than a few hours at a stretch. This will also be consistent with your banging hypothesis which was only heard after a day or two when it got lost. And also with the fact that no immediate sound disturbance was registered with the controlling ship. I of cou…

"It imploded right away" explains everything. "It imploded later" requires at least two failures, first of power/comms, and THEN of the structure itself. Occam's Razor

No, it doesn't as it would depend on the root cause of the implosion, like whether or not it crashed hitting the bottom then imploded or imploded partially descended from it's target depth. Slamming into the ocean floor would point to other things than the structure itself being the root cause.

It's not clear from the headline - but the debris field is on the ocean floor and was found via the USGC's remote operated submersible vehicle.

Yes on the sea floor but according to BBC:

> Debris patch was found by an ROV from the Horizon Arctic, a Canadian commercial vessel which arrived last night near the Titanic wreckage site.

> It was loaded with support equipment and was also carrying an Odysseus 6k ROV that can reach depths of 6,000m.

This story is weird to me

Considering the current geopolitical weather and the presence of Russian submarines, you'd think the US army would be able to locate the missing object in no time, even with a triangulated location, they failed

Worrying times

This wasn't boldly going where nobody has gone before. Getting that deep safely has been a solved problem for decades.

I agree but not at 250k a head. It should be safer, but everything is done to a price point and I'm sure those on board recognised the risk of such an expedition.

Do you think there will be a 125k refund since it was a one way trip?

Why has this sub been so hard to find?

I keep seeing reports that they've search an area "the size of" Massachusetts or Connecticut. Shouldn't OceanGate have recorded the exact coordinates where it was released and then been able to localize its possible location to a small area around that by modeling ocean currents or something? My understanding the Titan was designed to sink to the bottom and could only move very slowly under its own power. I know OceanGate was cocky and cut a lot of corners, but I just can't believe they wouldn't have the exact release location recorded somewhere, even if it was just an automatic track log on their ship's GPS navigation system.

Yep, fair point - found not by not the USCG itself but by the Canadian merchant vessel assisting in the search.
