African skies:
Summary : two unstallable airbusses stalled and fell into the sea.
There is thus something wrong with the flight control systems.
Disagree. If anything, it proves that the Airbus is too good for its own good.
As I read this, modern FBW aircraft are so symmetric, so stable, and the engines so perfectly synched, that the aircraft will remain stable even when pancaking downwards vertically with a pitch attitude of 20º nose up.
Whereas a 1950s aircraft, like the 'modern' b737, will have so many imperfections in its manufacture and operation that it is bound to drop a wing. And once you have dropped a wing and the nose lowers, you are instantly out of the stall and into the much more easily recoverable dive situation.
But I hardly think that regressing to 1950s manufacture and systems is the way forward. I am sure it is not beyond the wit of Airbus software engineers to program a nice and easy wing-drop (or a thrust reduction), when the aircraft detects a super-stall condition, so that the aircraft exits the nose-high pancake situation.
