The calls for more and better training make me wonder why we don't just train for the relatively rare over pitch characteristic that the MCAS system is intended to prevent. If we can't actually train for that then why are we suggesting that the solution is just being quick to turn the system off? What level of unreliability is required to make it better to just never turn it on?
