This is probably very non-PC, and I do not mean to decry in any way the loss of those killed at Shoreham. However, there seems to be a totally knee-jerk, "must be seen to do something" by the fun police at the CAA. We have multiple deaths in major road accidents, no one stops us driving on the motorways, people are sadly killed in rail accidents, no one stops us taking the train, major airports are in conurbations and large aircraft fly over them everyday. The UK airshow industry has a pretty good safety record and whilst some appropriate tweeking might have been necessary, IMHO the regime being applied to airshows by the CAA does seem did proportionate.
