this is probably a noise post.. but..
AF447 found itself in a certain space and time - and we need to understand the information and decisions that led to that space and time.. and what the conditions were at that space and time.
AF447, craft and crew, then had to deal with what they were dealt - and we need to understand what both did, what the results were, and why.
That's what needs to happen for the future of aviation and closure for the deceased. The rest is fluff.
Pilots don't intentionally do 'stupid' things, engineers don't intentionally design 'fragile' aircraft, and companies don't intentionally sell 'fragile' aircraft... The crew was experienced, the aircraft and the airline have good records. Let's back off on the character assassinations and pet theories and try to understand what clues we have.
As you were,
