Saw what seemed like a summary of the problem: The 787 MAX was different enough in behavior than other 737s that Boeing should have and didn’t provide the necessary pilot training.
It appears that no customers have cancelled orders for the plane.
That 737 Max has been a disaster for Boeing, but I would not call them down and out yet. Their 787 is in a good spot to dominate the long haul international market with the decision by Airbus to cancel the A380. Both great airplanes but what happened to domestic here is happening to international. Carriers are choosing shorter, hub based routes. Routes the A330 and the 767 and 737 can deliver on. For those long haul non-stops the 787 Dreamliner is a terrific airline for. I think for the next 20+ years, development of the super jumbo as a platform is dead.
