The best has to be "Its In The Air" staring George Formby made in the mid 1930's. Story is that our George joins the RAF by mistake and gets up to all sorts of daft antics. Lots of "crazy flying" from old prewar aircraft flown supposedly by George, but in fact by a bloke called Jimmy Wells who was a member of 600 Sqn AAF. Lots of real RAF people and a real RAF airfield used for the filming to save the production company money.
The film is a complete farce, and funny if you like that sort of thing.
