Flying the Hump
The first cargo-carrying flight over the Hump flew in April 1942, hauling gasoline for the Doolittle Raiders. Throughout the rest of the year, Tenth Air Force faced a shortage of reliable aircraft, facilities, and personnel. When Air Transport Command (ATC) took over from 1943 through 1945, they flew 456,977 flights transporting 685,304 tons, nearly sixty percent of which was gasoline.
