Then there should be some allowance for the time from establishing positive buoyancy to float from the wreckage at the bottom of the ocean up to the surface.
About 'the bottom of the ocean' part... given the extreme depths in that area and how much air cavities (& their gasses) compress and crush going down there, I would wonder whether those victims who actually went to the bottom could be refloated even after 72hours. For what it's worth.
I think that
ttcse is correct. Beyond a certain depth, a body is unlikely to ever return to the surface, due to the very high pressure exerted by the depth of water.
