Boeing says they did it, the FAA says they did it.
Boeing issued a software update for these planes that wasn’t provided by the FAA because it was evidently during the Government shutdown?
The issue here is a software / computer related to the new engines and pitch during takeoff (
MCAS). These planes require special training.
So, it’s not totally a plane problem: It’s a combo of the plane but mostly the lack of transparency to pilots and the new training needed to take off and fly the plane that isn’t a typical jet.
