Agree "Dawn Patrol" was the all-time great. Shot with surplus WW1 aeroplanes flown by unemployed ex-WW1 pilots - of whom they (Howard Hughes?) killed more than one, I believe. As a boy I was thrilled by "The First of the Few" - the Spitfire story with some superb sequences flown by Geoffry Quill, I believe. At Middleton St George "Sound Barrier", featuring the Swift prototype, was a cult film, mainly through morbid interest amongst the stus in what it looked like after you augured in vertically after "losing it". I think they detonated a 1,000lb charge and scattered bits of aluminium around the crater. At that time we were issued with bone domes for the first time and one of the stus with a particularly black sense of humour stencilled "Dig Here for Fred" on the top of his. Memphis Belle and The Fighting Lady were tops for WW2 combat photgraphy.
