Machinbird is right: it is perverse to suggest that the aircraft heading and track (and from them, allowing for the surface wind, the degree of sideslip) at impact are irrelevant.
It is also presumptuous at this stage to assert that the heading was necessarily random, wandering, and completely outside the control of the PF. In the absence of FDR data, it might give some indication of the minimum track-mileage from LKP to impact, and hence an idea of the mean angle of descent.
Quote from HeathrowAirport:
"There are two flights from Cayennes tonight. SOCA-LFPO...
...Does anybody know which flight they are going to be on?"
Preferably not the same one. Presume the QAR cassette/card, if found among the retrieved avionics-rack, would not have been sent to Cayennes yet?
Quote from The Telegraph (London):
"Robotic underwater cameras have shown many victims still intact in their seats in the smashed fuselage of the Airbus A330 jet from Rio de Janeiro to Paris.
But both those bodies recovered had disintegrated while being raised through warmer water and stronger currents to the surface, rescue officials said.
Now two Paris judges overseeing the recovery operation have said more decomposing bodies should not be brought up from the wreckage."
I wonder if loose bodies could be placed in an open-topped tank –
say, 2m x 0.7m x 0.7m (weight 1 tonne plus the weight of the tank itself) –
to bring them aboard ship in cold water.
