I suppose an electrical fire is another option, as the ballast released by the self-dissolving bonds might not be enough to bring it to the surface on its own. Or they could be bobbing around on the surface somewhere.

Yeah...I still find if crazy that they dont have a mechanism for opening the hatch from the inside. So they could be bobbing around the Atlantic on the surface and they still might run out of air.
