Actually, Boeing is charging that the AF team did a huge amount of homework in order to keep the Northrop/Airbus team in the running, and then got so proud of their homework that they forgot to play by the rules. I can see that happening. One need not charge the selection team with malice aforethought -- a loss of focus on the objective selection criteria would explain it.
All we've seen is the press releases, of course. but the GAO saw enough to at least say "wait a minute...."
There is no way the USAF team passed on Boeing without being very careful to cross their T’s and dot their i’s.
