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?
This is obviously not aimed at recovering the whole wreckage ; main goals are:
1. finding and recovering the flight recorders;
2. finding and recovering the maintenance computer;
3. recovering the passenger bodies;
If needed (in case those recorders canot be exploited to fully understand the crash) any other pieces of the wreckage that could be usefull for the investigation to understand the crash would also be recovered.
Detailed pictures in situ can also tell a lot to the BEA without the need to recover all of them.
