Even if the FAA recertifies the Max there’s a number of other countries that are signaling they will never certify these planes for service.
Seriously, the reputation of the Max is now the thing that is not salvageable and Boeing should simply cut their losses and come up with a new design.
Delivery requires acceptance.
I have every confidence that the 737 MAX will be discontinued. Won’t ever be another one commissioned and existing airplanes will be become cargo aircraft.
Passenger airlines simply won’t fly it.
