I remember being allowed to enter the break at 330 kts, 45 degrees of bank,
in a KC-10 at an unspecified forward deployed base!
Yes, I know its not a fighter and we are very speed / bank limited, but it was really really cool. Unfortunately, some "old guy" was at the base one day and saw a KC-10 come up initial. Suddenly we were forbidden to even using the overhead -- something everything USAF pilot is trained to do at UPT.
It was brought back later to our "procedures", but they put more limits on our speed and bank.
