I find this thread a little bizarre as between the CAA - MAA - EAC - BADA the Rules and to a small degree, self regulation of air show participants makes anything vaquely dangerous virtually impossible. Ramstein and Haddon-Cave between them have sorted the fun flying out. Gone are the days of post show departures being the best part of the show for exmple, and Crowd rear arrivals require a specific and written document of authorisation and few air show participants have it. RAFAT do, as do BBMF and I believe the Blades do but very few others.
The comments concerning perception od what servicemen get cost free is many years out of date and suggests a crevace on a shoulder never mind a chip.
