Will add, that in the Airbus, the other pilot may not see what the PF is doing. With Air France 447 the Second Officer in the left seat did figure out what was going on, but his nose down input was canceled by the PF's full aft input. The "Dual Input" aural was mixed in with all the other level 5 warnings "STALL STALL TERRAIN dual input TERRAIN" you get the idea.
