Just an analogy:
The FCOM says about High Angle of Attack Protection:
Under normal law, when angle of attack becomes greater than alpha-prot, the system switches the elevator control from normal mode to a protection mode in which the angle of attack is proportional to the sidestick deflection. (...) If the pilot releases the sidestick the angle of attack returns to alpha-prot and stays there. (...) To leave the angle of attack protection the sidestick must be pushed (...) forward.
When I first read that, I just thought - well, that's logical, and went on reading. Prior to the two incidents, I never realized that, when this happens in cruise and the SS is not pushed forward, the airplane zooms up 3000 ft.
I don't think AF447 will happen again - until everyone has forgotten all about it.
P.S.
Had the pilots of the AF 'level bust' incident been told about the THY incident?
