Runaway! Stop and think what that's really meant to 737
pilots over time. Whrrr...Whrr... of the trim wheels
spinning away without input. EASY, we have a recall to
fix that.

This is DIFFERENT! Because of the component fault situation
AOA, the stick is shaking.... a whole different and scary event,
especially because the plane seems to be in a routine flight
condition. Nobody would really notice that in such an unexpected
time the trim wheels are ever so discretely moving, and PAUSING...
due to inputs, but then relentlessly resuming their travel. Very
sneaky while a another perceived crisis is unfolding.

No reasonable person should just casually roll off their tongue,
This is a runaway stab, they should have selected cut out.

Don't know about the Boeing factory, but out in the real world there
are NO 737 Max flight simulators where this could have been
observed/trained. (and in some airlines NO pilots knew their
familiar 737 had been changed enough to include an unknown
automatic flight control input)

It's NOT a runaway stab... for most normal 737 pilots out there!

The stick shaker is still going, with the attitude and power this
should not be possible. Who would be thinking stab trim at this
time? Remember that in daily life those Whrr.. wheels are so
often doing their thing in the background. It's not abnormal if
one is otherwise stressed out.
