If water were the filler, it wouldn't be controlled. If the buoyant foam were used with lead inserts, that would be more controlled. By lead inserts I mean droppable ballast that may release on command. Why would one use droppable ballast on a flier sub? If the main hull flooded through an impact or something, you would still want the buoyancy to float to the surface. This is just a thought though. I don't know if the buoyancy would be needed if the cabin flooded (it may still be buoyant enough without it).

Good question.  I don't know.
Does Jon know the answer to this one?
I would think an inner pressure hull is the answer. 1ATM and a flier...
