[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]When would the oxygen be up? If they're bobbing on the surface, do they still need the oxygen reserves (sorry if this is a dumb q) or can they survive encapsulated for a while?[/quote]
The O2 will run out, such a horrible design flaw. They could die while floating on top of the ocean.[/quote]

Makes sense though. In order to withstand the pressures at 12,000 foot water depth, you'd want a smooth exterior surface to increase tensile strength. You can't have portholes or doors, as those would be weak points in the design that could fail under pressure. Even external attachment anchor points could compromise the tensile strength of the surface of the hull. [/quote]
Are submarines designed so that the occupants are unable to exit? These people are locked in, it’s a torture chamber. God help them if they are floating on the ocean surface unable to escape.[/quote]

Submarines don't go anywhere near this depth.  [/quote]
I know, but it seems to be a major design flaw to have the occupants locked in, unable to ever escape.[/quote]

There's no where to escape to. It's safer for all to have a sealed in chamber.[/quote]

Well, there are weights that they can release to get to the surface.  So in theory, they could do that and then get out.  Still no guarantee anyone would find them, of course, but even that isn't an option due to the design.[/quote]

GPS would come in handy here.  Assuming no failure in the electrical system.[/quote]
