Pilots have been busting display airspace since time immemorial and trying to link it to the relatively recent AIS troubles, however dear to your heart, rustle, as FD says, is barking up the wrong tree.
I was involved in a bust by a light a/c of a Reds' display at Henlow several years ago (not sure if it was a TRA in those days.) Once the intruder was seen to be leaving the area (I was on radar) the Reds ran in, only for the intruder to turn round and come back!
I'm involved in several special events in the course of the year and we go out of our way to publicise them, both through offical channels and directly with adjacent airfields. It still doesn't work, sigh.
A balloon lifted off just north of Old Warden last year with a Spitfire displaying. The balloon had a very famous name on it!!
I imagine the passengers appreciated the look of the Spit they must have got.
