Yes, that's RAF Odiham 55 years ago...
318 RAF aircraft on static display, then a 27 minute flypast of 641 aircraft, starting with a Sycamore chugging past at 74 KIAS and ending with a Swift at 580 KIAS in afterburner..... (The Swift's engine seized on its way back to Chilbolton, but it managed to land dead stick!)
And this was only 6 weeks after the almost as impressive Coronation flypast.
