Tim's weather analysis
I am also very curious about the temperature "cliff" coming out of 3 updrafts in the turbuence. Could there have been a combination of wrong speed (pitot) and stall/fall with that cliff getting out of the turbulence? Isn't it really an exceptional situation (may be not weather wise, but flying wise since CBs are usually avoided), an hence not taken into account by computer/checklists? As for the "criminal investigation", it is an automatic administrative procedure here in France and does not imply that criminal behaviour is being suspected. Thanks - Gilles
