All airplanes can stall, even the stall proof airplanes.
maybe the cargo shifts, maybe something happens, maybe the
A&P mis-rigs the elevator or the stop breaks.

I like the "maybe something happens" method of stalling a plane. I was
(of course) referring to airplanes that have not broken, and are being
flown deliberately into a maneuver. Not all airplanes are capable of
all maneuvers.
