Airbus Industries has every reason to find the data recorder and CVR. The causes of this crash if at all aircraft/design related must be discovered with haste. A willy-nilly approach to avoidance is but an invitation to future losses if we do not know the point(s) of failure that led to it.
Air France on the other hand faces the ambiguities of whether their crew acted imperfectly, if perhaps weather and the aircraft systems conspired together in an unwinding tapestry of fate with an undefined X-factor, typical in certain crashes of late, that will almost always be applied in the direction of the crew when it comes to blame.
