That would seem to be the nature of Lockheed unflyable entry in the
competition to build a prototype ATF, none of it mattered.


At that point in the competition (two designs chosen of seven paper
designs) unless the USAF did a lot of inhouse simulation/studies/ etc.
about the only thing they have to go on is the data the manufacturers
submit with their proposals.

Excuse me, but this must be some sort of a time warp that I didn't
live through.


It's probably that age thing kicking in ;-) We're talking about the
decision process the LED to the building of the YF-22 and YF-23.
There were seven designs submitted from seven different companies.
They ranked:

1. Lockheed
2. Northrop
3. GD
4. Boeing
5. McD
6&7 Grumman and Rockwell (don't know the order)


It was at this point that Lockheed and Northrop were chosen to proceed
to building prototypes. Lockheed teamed with GD and Boeing and at
this point GD said "uh, we got some bad news about your design."
