I can confidently say I have read every single MAX post on these (and a few other) forums, and I think it is time to repeat a question that has not been answered by Boeing.
If you have a real runaway trim B expects you to take action in 3 seconds, and save the day. When they designed the MAX, they found the stick force to light in certain regions of the envelope, so they introduced a 10 second runaway trim. If the pilot responds the way B expects they will cut-off the trim so the solution to the stick force problem doesn't work. How was this ever certified?????
