Just to Bring corrections, it seams that both the CEO of Airfrance (Gourgeon) and the head of communication made statements about this tragic accident, and not a mere muppet.
Of course everyone could speculate about what caused the loss of thies aircraft and the probable loss of its occupants. So far, it seams that a failure message mentioning the electrics was sent via ACARS to the MCC, and maybe, a loss of pressurization (how can those two events be related?) which remains to be confirmed.
The sending of the ACARS message does not necessarily mean that the event affect the safety of the on-going flight. Besides, we have absolutely no idea (only AF, airbus and the BEA know that) what electrical failure was reported (total failure, partial failure??).
For sure, recovery of the black boxes is needed for both the airline (and probably the insurance company) and the manufacturer (with underlying national interests since France is twice as involved by the operating company and by the manufacture). I hope the French government will do whatever it can to find these precious black boxes that will probably reveal how the slces of swiss cheese lined up to lead to this dramatic event.
