He found that meaning at the controls of an airplane, and in the flak-and fighter-filled skies over Occupied France and Nazi Germany. The plane was a Boeing B-17 Flying Fortress. Morgan named her the Memphis Belle in honor of his fiancee, a Memphis beauty named Margaret Polk. He and his crew flew 25 successful daylight missions over Europe in the Belle, and were immortalized by Hollywood director William Wyler in a 1944 documentary called The Memphis Belle. In those 25 harrowing missions, Morgan never lost a crew member. The only casualty associated with the Belle was Morgan's engagement to the plane's namesake; it simply couldn't survive the War Department's publicity demands.
