Already and understandably so the CAA have made knee jerk legislation with no evidence to back up that legislation banning vintage aircraft from flying aerobatic displays and who knows what further restrictions will be placed on airshows as further evidence unwinds ?
Err, terminology please. The CAA have not made any form of legislation, they are not empowered by the Government to do so. They
have put in place temporary measures and will review as necessary.
Let's look at this another way. A Gnat and a Hunter, both operated on Permits to fly, both based at North Weald, crash within a couple of weeks of each other. Now, I've no real visibility of how many 'vintage' jets there are out there, nor do I know how many operators, engineering organisations etc support these jets. To date, no one has presented any evidence of technical malfunction, or not. We, the great unwashed, simply don't know.
Personally, I think the measures are, to use your word, understandably prudent.
