LAFAYETTE ESCADRILLE

You wonder if this is a personal true story because William Wellman wrote it and his son William Wellman Jr is in it playing a role named Bill Wellman. Lots of clues. 

William Wellman's last film. So widely hated by his surviving squadron pals that he asked Warner Brothers to take his name off of the picture. 

Note: young Clint Eastwood role. Just imagine unassuming Hugh Jackman. (You can't.)

Jon likes more ladies in cinema so doesn't see the flying ones.
