Lately I've been into reading books about military aviation history. I've started with some WW1 stuff and am now into WW2.
Many good books out there. I just finished two good books on Eric Hartman. Both basic biographies of him. Very interesting guy with 352 confirmed shoot downs. He wanted to be a doctor, but that goal was overcome by events. Eric was captured and spent over a decade in a soviet prison camp. He was released and later went on to fly F-86s in the German Air Force post war. Although Hartman was our "enemy" during WW2, his story is one of conviction, faith and courage. For him to survive as long as he did in basically a soviet gulag death camp is a testament to his character and shear willpower. Very interesting individual.
German Fighter Ace Eric Hartman: The Life Story of the World's highest Scoring Ace (Schiffer Military History).
The Blond Knight of Germany: A biography of Eric Hartman.
I thought both books to be very well written and documented.
