Been doing IAT/RIAT for decades and only at Greenham did I experience problems getting out. Key to that seems to be to leave when the Red Arrows start their display.
There are good shows around still, but they are smaller and generally few in number. I go to a number of fly-ins now and that also seems to help quench the thirst.
But for sure, we will never see the days again of inverted Lightning passes or formation F-104 displays. We do however still have some awesome machinery at shows - even modern stuff like V-22s and F-22s.
