To be clear, I do not object to the 'verdict', but I do not think it helps to suggest that all the issues raised by these crashes can be dealt with just by giving each sensor one or two somewhat arbitrary thresholds beyond which they should be ignored. While I cannot think of any reason not to have adopted the proposed solution within MCAS, and it would have prevented the Ethiopian Airlines crash, it would not have eliminated the possibility in other circumstances (possibly including Lion Air), on account of the other problems with MCAS. If, in these cases, the sensors had failed to a plausible value (say, 15 degrees), the outcome would have been the same.
