MTM,
So which airfields have you placed your - to scale - overlay onto in order to predict a much smaller number of airshows next year?

Hey, I said it was unscientific, but so far it includes Duxford (M11 -no surprise really), Culdrose (row of houses next to the viewing enclosure at one end, A394 at the other), Cosford (the railway station) and Waddington (A15) amongst others. At Farnborough it is well within the airfield perimeter, and at Dunsfold it is open countryside.
But if I have done it, you can be sure that somebody in an insurance office is doing the same, with as little science as I used, and will be using it as a reason to bump up air display premiums by two or three hundred percent for next year.
