My dad was in the US Air Corp now known as the US Air Force. He was in the 56th Fighter group and they flew the P-47 Thunderbolt. I have a few pics that are so awesome. The 56th was the most elite fighter group in WWII against Germany. my dad told me they would escort bombers over enemy territory to bomb ball bearing factories and such which is the exact storyline of the movie 12 O'clock High.
