I will read that with interest. More reasoned information the better. Many thanks. Yanrair

this one is good too. An off duty jump seat pilot seemed (I say seemed because everything we are getting at the moment is from various sources) seemed to have just done what I have been saying from the start. Turn off the switches. And it was all a big non event. On the flight prior to the fatal one.

For completeness there are four ways of stopping the stabiliser moving
1 Grab it (that was the main way until about 25 years ago, but because it did result in losing the skin on your knuckles, Boeing put in a brake like the one one a Mormon cart. A simple friction brake on the periphery of the STAB wheel. Very effective though.
2 Trim in opposite direction - only works as long as you are trimming. When you stop, STAB starts moving again
3 Pull the control stick - yoke if you like - in the opposite direction. That stops the STAB. Now, this may have been changed on the MAX, and if it has we have a factor. Unless the pilots were told about this during training.
4 Turn off the switches - this works in every situation.
Cheers
Yanrair.
