crashworthiness of a composite aircraft is there in a photograph
Actually, just for the sake of clarity, the A400M fuselage is made of aluminium, which appears to have been totally consumed by fire. The composite wings and tailplane appear to have resisted slightly better. In any case, it'll be a few months before the accident investigation can tell us anything about the crash survivability aspect.
It is in any case a sad day for us and a reminder we still have a lot to learn to make flying safer.
