MCAS is not trim runaway...so what memory procedure is to be used? This is letting the tail wag the dog on fixing the situation.

The logic of the situation, the immediate response, as well as a longer term solution in flight, appears to show that switch configuration of the NG was better, not necessarily the best, but a better solution that the all cutout solution in the MAX, especially with the known manual trim wheel issues.

Looking at the switch config only, the NG config at least allows for elec trim when shutting off the AP...that has more value that trying to turn the manual wheel with its respective limitations.
since the Captain has overall authority, why depriving him of the possibility to shut off HAL, if he choose so? Actually why that was the path chosen? I speculate that the airframe will have issues with certification if MCAS could be disable flipping a swtich!
