To maintain the uninterrupted supply to China, U.S. and other allied leaders agreed to organize a continual aerial resupply effort directly between Assam and Kunming. Airlift history Haynes, 1942 Tenth Air Force was hampered by a constant diversion of men and aircraft to Egypt, where Nazi Germany was threatening to seize the Suez Canal. Its Air Service Command was still en route by ship from the United States, forcing it to get aircraft and personnel for the India-China Ferry from any available source. Ten former Pan American World Airways DC-3s and flight crews were sent from the trans-Africa ferry route to outfit the new operation. 25 other DC-3s requisitioned from American Airlines in the United States could not be moved to India for lack of crews and were later integrated into the complement of the first transport group committed to the airlift. The command structure of the India-China Ferry was fractured after senior officers in both India and Burma made competing claims for jurisdiction, with part of the authority given to Gen.

Haynes was a fortuitous choice to be the airlift's first commander, as he had just completed an assignment as a key subordinate of Brig. Gen. Robert Olds. Olds and his staff had founded the Air Corps Ferrying Command in June 1941 and pioneered overseas military air transport, including use of the South Atlantic air route by which aircraft, personnel, and cargo would reach India from the United States. However, at the time the India-China
