Black Box

Reference Flight 447 Air France from Brazil

The focus of recovery of this horrid plane crash has been on the black boxes. What about the 200+ passengers? Are they not more important? The plane crashed, return to the families and friends of these victims the remains of their loved ones.

The black box will tell why the plane crashed, but it doesn't give anyone anything. It has already been determined the tubes had not been replaced as recommended. Do we always have to be definitive in laying the blame?
