The ETOP’s clearance for 757 and 767 was based on on statistical significant non ETOPs operation that was completely irrelevant to an RMPA. Hence it would be a fresh start with a fleet size that could never attain the required operational hours. Do you know how the ETOPs cert process applicable at that time worked?
Military aircraft tend to have small fleet sizes so it's vacuously true that it's difficult to attain the required operational hours.
But since MPAs don't necessarily have to get FAA/EASA certification and we were talking about demonstrable, readily
observable trends in the early 90's this is all irrelevant.
Naturally, as an alleged contributor to a disastrously failed project, you have a strong
motivation to generate apologia and revisionism.
"We were waylaid by technological trends that we couldn't have seen coming."
That's your argument. It's utterly, demonstrably untrue.
@LowObservable chimes in with his typical "USA boogieman" apologia to try to help you out.
