@emilygorcenski If you want the full story, do a FOIA request on the whole sordid history of F-15 Contract Change Proposal 39. McAir were the most arrogant assholes I’ve ever dealt with, even if they could make a brick fly.
While you’re at it, pull the history of the Common Engine Bay proposal, and the years they spent opposing the ability for the USAF to second-source engines for the F-15.
Man, it’s over 40 years later and I still hate those disingenuous asshats.
