That is a fact, and it happened the day before. And of course the recent Boeing simulator sessions with line pilots at Seattle showed that they all stopped it. But of course, they knew what to expect, didn't they. But they were 737-max airline pilots and not Boeing test pilots.

Let’s back off competent pilots knowing to cutoff stab trim. Let’s focus on a couple at LionAir that trimmed when their commanded attitude required it. And one who didn’t trim. Why didn’t he trim. Not much real hand flying experience?
