People are still people, man. If they have the money maybe they should pay back the rescue efforts if found alive (which won’t happen), but it kinda sucks to say “welp bye” and let half a dozen people slowly die if you could’ve helped.
I imagine if they located it and it was as simple as bumping it slightly with a remote vehicle, there's still some infinitesimal chance, but it seems all but certain they're doomed.
Something this small could simply be floated to the surface. With big things there no way that can be done. Still difficult af but possible, don't know if things like that already exist.
That was the spec sheet provided by the company, but without any backing info, testing, or engineering expertise. The more digging people have done on this submarine, the more of an absolute shit show it is.
If the sub is still at 1atm internal there is no issue...if the sub is at 380atm down at the Titanic then.....again nitrogen narcosis is not the issue as that 4000 tonnes per square meter of force makes it irrelevant.
