I alluded to this earlier, the XL Air /Air New Zealand A320 crash off the coast of Perpignan. It pitched up into a nose high attitude, stalled and fell into the water below. This AirAsia flight seems to have made a carbon copy manoeuvre.
My suggestion that this crash might well be similar to that one was lost in all the Airbus v Boeing control philosophy discussion.
