...does anyone have an idea of how they would lift the wreckage to the surface from that extreme depth (+13,000 feet)? I assume the pictures have been taken by an un-manned sub; right?
It is taken from one of the three Remus (those small yellow torpedoes used for scanning the sea bed) in another close up dive for taking those pictures after completing their area scan.
For the lift to the surface, they would certainly use some inflatable stuff attached by ROVs.
