I once saw stated in a documentary, that at least 10-15 years ago, the Air Force started seriously cracking down on stunts by pilots. One example they gave is that B-52 crashing near an airport when the pilot tried to pull some stunt involving a very high-banked turn.
Oh, they frowned upon at that time too, 1990. The pilot was National Guard (on rotation to Panama for drug interdiction) and I don't know if he got in trouble or not. Probably not much from his own command (they're pretty laid back) but if the Wing Commander was notified, ha may have gotten spanked. They could get away with a bit more down there than they could in the states.
I saw an F-16 tail walking down the runway one time, something usually reserved fro air shows.
