Can't somebody with the right contacts arrange for a flypast of eight Bears with a few Tonkas in attendance
Funny thing.
In a previous life I was Secretary to the RAF Participation Committee (probably non-existant today) whose prime role was to approve military aircraft participation at air shows. The Chairman would not even debate my suggestion that the Luftwaffe be invited to participate in the annual B of B at home days. Completely inappropriate, he spluttered.
So unless the 21st Century RAF has leaders of vision, I guess there's no chance.
ps. The same Committee also banned participation of the "Soviet Bloc" air forces at the first Greenham Common Airshow.
