beyond a certain depth, if a submersible fails, you just die
it's like a space ship in that regard
worse than a helicopter imo
at least there's a tiny chance you land on something soft and don't get bisected by debris
but if your sub goes bad, you are definitely getting the bends if you don't just get crushed/drown
modern helicopters can even land safely while autorotating, which isn't pleasant but it'll keep you from dying instantly in the crash. There's no equivalent to that with subs.
It's way, way worse than a spaceship. On a spaceship you've generally got enough water and oxygen via the fuel cells to last a week or two, you'll probably die of overheating or CO2 (CO2 is also the issue with a large sub disaster like the Kursk). On a sub like this...you'll freeze or die of lack of O2.
Also, loss of pressure on a spaceship is bad but survivable. 1 atm to zero. The Byford Dolphin was 450 meters down and that was 9 atm to zero. The Titanic is 3800 meters down (0 to 380 atm, the other way round, explosive compression.).
If Apollo 13 had happened on a sub it's arguable there'd not be enough left of the craft to show up on sonar.
Wait what difference are you trying to describe between lack of O2 and overabundance of CO2? Both of these go hand in hand in these situations right? There isn't a CO2 scrubber on a submarine that doesn't work either. That seems like a terrible way to go because CO2 hurts when it's built up in your blood
I don't know about submarines and CO₂ scrubbers, but if someone locked you into an airtight room, you'd die of CO₂ poisoning long before you ran out of oxygen. I assume if you can remove the CO₂ somehow, then you'd run out of oxygen eventually.
There are chemical CO2 scrubbers that don't need electricity, so in principle you can die from lack of O2 while having livable CO2 levels. (though now you mention it I feel that the sub that failed it's depth rating test due to hull fatigue and then posted an FAQ about how it didn't need a rating because "disruption" does not have emergency CO2 scrubbers)
That is true, but I'd still rather be stuck in LEO than on the abyssal plain. People have been rescued from LEO, people have spent years stranded there. If i recall current record for submersible rescue is at half the depth of Titanic, and was a very very near run thing.
