I have no idea how this wonderful manoeuvre was performed but I remember being there at the age of ten having managed to exhaust my poor old Mum with my blandishments (my Dad was RAF and was killed early in the war) and persuade her to take me. This was my first exposure to an air show and led to a lifelong delight in elderly aircraft (well, they're elderly now).
It seems almost impossible to me now but I actually saw the Avro 707 series and the BP 111 in the air plus all the other wonderful aircraft shown in that film such as the Sperrin.
I'm in danger of weeping on my keyboard, at the age of 75, when I compare what we saw then with the state of our aircraft industry now.
But watching that short film has been absolutely great and I think I'll have an extra glass of wine this evening, to celebrate what once was world leading.
