Amazing how all of this could have been avoided even without “the fix” if Boeing had just included a second AOA sensor with a miscompare feature in the standard cost of the aircraft. What gross misjudgment about additional profits on optional features.
The MCAS code would have still been “bad”, but the AOA miscompare would have saved the day, and a fix implemented without the whole fleet being grounded for an entire year, along with a complete loss of confidence in Boeing.
