I don’t think I’ve ever seen the competing designs to the McDonnell Douglas design before. Were these public at the time like with later aircraft competitions? I’m thinking of the YF-17, YF-23 and X-32.

There are drawings of the Fairchild and North American ones in the PDF (page 60) as well.

The Fairchild one looks incredibly Ace Combat (I think it's the super wide engine pods).

That’s what I meant. The PDF is the first I’ve seen.
