TOGA and nose down stick.
TOGA and pushing nose down on the stick will get you nowhere in some deep stalls.
The 2 moments neutralise ach other.
The engines lifting the nose, and the tail pushing nose down.
The remaining vector is ZERO and the only velocity is going vertical down till impact.
Stalls come in lots of forms and shapes.
Prio ONE is to get the nose down.
Stick, closing of throttles, trim to nose down, all tools are good tools to get the nose down.
But you have to get them all working together.
At FL, this can take several thousands of feet.
But PRIO ONE is to get the nose down again. Even if it means dropping the gear in airplanes that allow it in the higher FL.
Never mind a missing door, if it can get you to regain control of the aircraft.
