It's not strictly a narrative, but the Canadian NFB docu-drama Aces: A Story of the First Air War is one of the best collections of WW1 flight footage I have come across.

Done as a grandfather's recollection to his son, it tells a tale of the progress of flight and its impact in wartime.

I also agree with Polovski. Aces High was a fine film. A little wonky on the historical opponents but enjoyable. The scene where Malcolm stands up to address the students and it suddenly cuts to him frantically changing a lewis ammo drum is some great film making. You get a real sense of the panic involved in combat.

S!
