A line of North American B-25 Mitchell medium bombers rests on the flight line at a USAAF airbase in the China-Burma-India theater during World War II. The lead aircraft, numbered 1589 and adorned with nose art reading "Darling Jill," typifies the personalized markings common among American bomber crews. Ground personnel inspect the aircraft before or after a mission, part of the relentless maintenance routine that kept Allied air power operating in the demanding CBI theater. Project: 218031
