That would be an interesting film on Hartman, there are a number of WWII aces that would make good movies.
For a truly amazing tale they could make one on Joachim Marseille (start of the desert).
Adolf Galland would be interesting as he led the Luftwaffe against the USAF.
***Lets see them make a film about Erik Hartmann, then Ill be impressed. The Baron has been in many other films over the years.***
The USAF came after WWll. No BOQ w/cable yet, those pilots were still in the Army.
