Great list! I would add 'Wings' to the WWI group, made in 1927, and has incredible stunt flying. (Clara Bow, Buddy Rogers, Gary Cooper)
I forgot Wings and worse... In a previous answer, I miscredited Howard Hughes as the film's producer. His WW1 flying film was Hell's Angels (1930)...
I also, thankfully, forgot that Hell's Angels in Vietnam flick... {...loud ick sound...}
