Gainsey: Absolutely. The story was that the RAF wouldn't let them cut a hole in the front of one of their Hunters for the camera. so they cut a hole in the front of the Hawker machine, chinagraphed a viewfinder on the front screen and sent the pilot off to fill it up with shots of the other Hunters flying. The shots of the burning Hunter on the ground were provided thanks to one of the JP's who, reportedly, put his Hunter down rather hard so they set fire to it again for the film.You can probably still get the film on old 78rpm records!
And here's another gem:
When they filmed the Dambusters at Scampton the Station was filled with actors dressed as Officers and Aircrew NCO's. No one actually in the Service knew who to salute and who to ignore. The order went round for all the actors to wear dark brown shoes (which they did).
The request was relayed to Richard Todd, who of course played Wg.Cdr.Gibson. He declined, pointing out that he had held the rank of Lt.Col. in the army and therefore felt no embarrassment dressed as a Wingco!
