OceanGate - with that name, I think they were onto something...
What a nightmare scenario. What about plumbing and water for 96 hours? How scary. Poor passengers!
Maybe they should look under water instead of under way...

How does one even plan for contingencies? 96-hour life support, but can specialized rescue subs get there in time?
I feel like a proper contingency in this scenario would be some sort of "instant death" system. Knowing you're going to die, but waiting 96 hours for it to happen sounds terrible.
I get where you're coming from but this sounds like an insanely bad idea. Perhaps I'd agree with you if there was something like cyanide pills people could opt to take, but even then I'm hesitant. There should be no way for one person (or some subset of people) to decide for everyone that now is the time to die; if someone wants to be in their head and push the limit and die at the last minute, that's their call and theirs alone. Also, if there is some miraculous rescue but someone has pulled the "instant death" switch, they've effectively murdered the rest of the people.
