David P. Davies' solution to a slight pitch up into a stall in the 707 used only the elevator, not the much larger horizontal stab, and the solution was safe, effective, and benign. The MAX uses the stab, and trims forward for up to 10 seconds at a shot. That's at least an order of magnitude, maybe two, larger trim input than Davies'. I refuse to believe that a correction that large is "only feel."
