Airbus A320 crashed in Southern France

[Des Dimona]

What seems undisputed:

1. Aircraft stayed roughly on the same track until impact
2. Small impact footprint containing all of the aircraft = no in-flight breakup
3. FL 380 until impact about 8 minutes
4. No distress call or ATC 7700 from the flight crew

If the AP was not on, there would very probably have been noticeable heading and speed changes during the descent.
If the AP was ON, the aircraft was in NORMAL LAW.
I think that no crew contact is the most disturbing question.
