Gen. Caleb V. Haynes, born in 1895, was one of the giants of U.S. military aviation. A "big, hulking mountaineer," as one writer put it, he spent nearly four decades serving his country as a test pilot and flight instructor in France during World War I; an explorer of new air routes across the oceans; a World War II bomber pilot who handled bombers as easily as others did fighters; a fearless transport pilot who pioneered the U.S. airlift operation over the Himalayas known as The Hump; a hands-on field and operations commander before, during and after the war; a true American military hero who earned countless accolades, including three Distinguished Flying Crosses; and - perhaps above all - "a pilot's pilot."
