The trailer looks pretty, lots of aerial combat

What other movies are good for us Blue Max geeks??? I've seen the movie Blue Max, which I would call down right unwatchable, if not for the planes.
And I have heard of . . . "A long engagement" at least that is what I think it is called.
Any others?
My favourite WW1 film by far is "Aces High" - the story of a new pilot joining an SE5 squadron. Excellent film, quite moving at the end.
