Re: Boeing 737MAX Grounding, General Discussion Thread, April 2020

Better training would probably not have saved the 2 MAX, yet if you look at the crew coordination and reaction times, they would still struggle with a serious fault in any modern airliner. Any other airliner is so much more fault tolerant, that the same level of crew proficiency is not causing huge...
