What could be recovered for 5M€? Surely not the wreckage itself? From the press articles, though, that sounds to be the intention. I'd have thought they'd leave the poor souls and just try and recover the recorders, but it seems they actually want to recover the fuselage?
Second thought: How will it be done? Is there a capable successor to the Glomar Explorer that'll be able to salvage stuff from such a depth?
