@Machinbird, RetiredF4:
You're right - however if I recall correctly from the mega-thread and the report's DFDR graphs, the PIO was on its way to being stabilised, and was almost there at the point the aircraft stalled (apex of the zoom climb) - suggesting that the PF was at least getting a feel for the roll aspect. Unfortunately the consistent backpressure (intentional or not) while doing so meant that stabilising the roll became something of a moot point as the aircraft went into a full stall.
