One crew member survived and I sure he has passed on to the investigators just who was at the controls at the time of the accident. The ATC tapes and the CVR will also be able to indicate who may have been flying the aircraft as well at the time of the accident.
Why should it be public knowledge at this point in time ? Let the investigators make this public at the appropriate time. I just hope politics don't get in the way of this investigation,as is usually the case up here.
