Beagle has expressed my own sentiments quite comprehensively, my own initiation to all things aviation and RAF in particular, was at Finningley, I believe it was 1962. I was very very young. I do recall the impact of a four Vulcan scramble, all anti-flash white. As for the present difficulties in mounting such shows, my understanding is that the iconic Anthony Blair PM, introduced , or presided over the introduction of, a restrictive ruling which prevented military personnel and hardware more to the point, from being used for public demonstration except for ceremonial activities? Thus to get HM Forces participation at an airshow, even their own, requires a degree of money to be handed over to either MOD or as is more likely the case, the Treasury!?
And this in turn has had a significant and noticeable impact on military participation at any public events since.
