Instead of reading historical/biographical fiction, why not read the real thing? For example, read "Stuka Pilot" by Rudel. It's an account of fighting in WW2 that would be dismissed as ridiculous if it was a Hollywood movie, but it is all real and documented.

Another is "Reach for the Sky" by Bader. Chuck Yeager's biography is also a treat.

Then watch that absurd "Flyboys" Hollywood fiction. What a piece of trash in comparison.
