two films - you babes are probably too young to recall:
Battle Of Britain - for which IIRC they raided the Spanish Air Force of much of their inventory in about '71 ish. Cambridgeshire was awash with great WWII formations for they flew/filmed much of it at Duxford
The Blue Max - early days of effects and excellent scnes of flying under the bridge.
Both films come to mind as having a plot of sorts too!
