> pilots followed that procedure

Were these pilots trained with the new procedure and the other pilots who died not trained?

Just to add, it was the normal "runaway trim" procedure-- nothing new.

The thing is, this revealed a vulnerability: real pilots in runaway trim scenarios do not do nearly as well as they do in training. And 737MAX ended up testing crews with runaway trim scenarios at a much higher rate than they had been at the past. Some crews failed.

No. It was the LA flight immediately prior to the LA flight that crashed.

They trimmed it back to normal a couple times, then just turned it off.

Sounds too simple to be true, but it is true. There's a toggle switch on the console that cuts off power to the trim system. It's there in case of runaway trim.
