I was at Finningley at the time the film was made. A Vulcan OCU pilot strayed into the filming area and wanted to file an Airmiss on a ME109 but was persuaded otherwise!
Later, we were invited to the 'Premiere' in down-town Sheffield ... so, in true RAF style, turned up in full Mess Kit with ladies in evening dress all transported in a grotty, asthmatic Bedford coach!! It didn't quite cut the mustard when we pulled up outside the cinema for the full red-carpet treatment complete with flood lights and media!
It was a good night but we received a few odd stares when we cheered a Vulcan bimbling along in the background of one of the dogfight sequences! It's strange, but try as I might, I have yet to see it again on the TV re-runs.
