but who says the oxygen inside that sub is still perfectly fine breathable and all that, apparently they have these oxygen filters onboard which work on batteries, if the battery is dead sooner than the oxygen runs out, the oxygen can turn poisonous if not filtered anymore



how could this have happened in the first place? i mean even James Cameron went down there with an entire professional team, with special radar on a boat directly above him monitoring his and his filming crew's whereabouts every second, back when they needed some authentic material for the film



and this one didn't have radar on a boat above them tracking them or what? i call that very unprofessional if so
