During WW2, Bob Hoover's Supermarine Spitfire was shot down over the Mediterranean & he was taken prisoner by the Germans. For 16 months, Bob tried to escape several times. Each time he was caught, beaten and placed in solitary confinement.
He never quit and ultimately escaped and stole a German FW 190 fighter. Bob knew that while flying a Nazi aircraft, he risked being shot down by allied forces.
