Hi Lyman,
The conclusion is beyond belief. It stretches the imagination that it could be true.
It makes perfect sense.
All the holes in the Gruyère cheese simply lined up that night.
At time 2.10.03 the flight deck loud speaker warns of autopilot disconnect, and is heard and acknowledged.
From time 2.10.09.6 the Altitude Alert deviation warning "C Chord" sounds and continues to sound until impact.
It is only interrupted by "Stall Stall", ECAM "dings", crickets, "Priority Left / Right", "Dual Input" etc.
No one on the flight deck mentions hearing anything. No one thought to cancel the "C chord".
The only device attempting to warn them that were stalled was lost amongst the cacophony of other aural warnings.
On previous aircraft, we had both the vibrator noise (unmistakeable) and the tactile feel through the control column.
Why was something similar not thought to be necessary?
