I am curious how we (the society) justify the shared costs incurred in searching for people involved in such a reckless mission.

Does the search team/agency simply eat the cost or does the cost get passed back to the insurance for the company, the company itself, or the CEO personally since he has the means to pay. Further, everyone on board has the means to pay for a recovery, should they too share some of the cost?

What I don't understand is, if it imploded, why didn't the boat hear the implosion? Surely that would be really loud. Louder than the 15 min audio ping that the boat is normally listening for.

Or half the east coast. The implosion[?] of the ARA San Juan was supposedly heard 6000km away by hydrophones at Ascension Island. ( https://www.ctbto.org/news-and-events/news/ctbto-hydroacoust... ) Or maybe they did and the data hasn't been processed/made public yet.

San Juan was 2300 tons and is made of metal.

Titan was 10 tons and mostly made of carbon fibre.

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

Or...you know...the logical explanation that they did not want to give their capabilities away and may have even used this opportunity to mislead.

Earlier quoted context omitted.

The sub had 7 redundant ways to surface (drop weights / ballast), several of which work without power, and one of which triggers automatically after ~20 hrs of exposure to seawater. The only way it wouldn't have already surfaced on day 1 is if it got stuck on something ( and lost power, unlikely), or it imploded.

What I don’t get is what factors could have caused it to implode now when it didn’t previously?

I know doing amateur rocketry pressure vessels work until they don't. Motor cases will gladly handle multiple launches and then on the 20th launch, explode. I think it's a matter of the metal fatiguing over time but I'm not sure how you measure the rate or severity.

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.

There was marriage at Titanic wreck for 36k a head 20 years ago. [0]

But I still hope that this will bring some innovation - in form of stricter regulation for tourism.

Are you sure about that? https://www.livescience.com/chinese-submarine-record-dive.ht...

That is a submersible. Military submarines (things that can travel thousands of miles, support themselves, have weapons, etc) appear to bottom out at ~2000m. At least one US military sub imploded well above 2000m.

Let's live blind then!

It’s definitely better for them, but its infuriating that this CEO died thinking he was a genius for building this shitty sub with very few safety precautions.

At least he died doing it and not someone he employed.

Honestly given all the red flags he ignored it seems like he had a death wish, or at the very least got a thrill from risking his life on these trips. Otherwise I can't wrap my head around the stupidity of the whole thing.

There's more to be said, but I'd say the training experience in a real-world situation alone is probably valuable. Helps identify actual stress points in the rescue process, for example.

Because it was interesting to hear about. Literally tens of millions of people thought that this was interesting to hear about.
