Here goes,

The Sound Barrier - brilliant film, brilliant aeroplanes, exceptional pilots...

The Dam Busters

Memphis Belle

Battle of Britain (good for the warbird business...)

A Matter of Life and Death... (Stairway to Heaven)

I believe the film Fido was referring to is "One of our Aircraft is Missing", by Powell and Pressburger, with Bernard Miles and Peter Ustinov among others...
