This jives with what I've seen from blancolirio, MentourPilot and others sources. The pilots should've had memory items to disable automation control of trim for the duration of the flight rather than all electric control of trim (including yoke-mounted switches), because aerodynamic forces were too large and altitude was too low to manually spin the trim wheels. I do hope Ralph Nader sues the pants off Boeing for murdering his goddaughter through negligent homicide. The FAA is also culpable for failing to oversee self-certification properly and getting too cozy (regulatory capture) with Boeing. As a consequent, equipment models including the whole line of 737 NG (-600 to -900; 2010 Ducommun structural parts scandal), 787 Dreamliner failures and 737 Max 8 and 9 are models I would not step foot on without a gun to my head.

I have read some of the earlier reports that they changed how the electric trim works. On earlier 737's, there were two switches: one to kill automated input, one to kill all electrical input.

On the MAX's, the switches only kill all electrical input. So those procedures literally didn't apply.
