Meanwhile, EASA goes its on way, apparently beyond the FAA requirements, and wants Boeing to show the Max is stable with the MCAS turned off... Which, as is likely if Boeing cannot do it, might be the kiss of death for the Max, and disastrous for Boeing. Especially if other certification authorities follow the ESA's lead, and the FAA reluctantly feels obliged to follow. Yet, showing stability is arguably the right thing to ask.
