Airshows are on borrowed time in the UK, at least anything that resembles an "air" show. The combination of Shoreham and rampant development of, and around, airfields is a pretty fatal one. If RIAT ever do get the push from Fairford that will be the end of that one as well, as there is literally nowhere else suitable left in the whole country for a sizeable airshow to take place.
Sad times and its all happened on our watch....
