@Dozy
that all the crew had to do, both to arrest the climb and exit the AoA/Alpha Prot mode, was to *push forward on the stick*. Hardly rocket science and, by my estimation, fairly intuitive piloting - no?
Which is what they did of course!

@Chris Scott
BTW, in the AAIB's DFDR trace, the sidestick parameter seems to give negative values for "up" inputs, i.e., stick back.
Reason for that is that with the pretty well universal right handed system of axes used to describe airplane motions a clockwise (nose up, tail down) rotation is positive. That means that 'down' elevator is positive. Although the RHS axes don't have to be applied inside the aircraft it makes sense to have a positive (forward) movement of the stick correspond to a positive (downwards) elevator movement.
