Air Transport Command and the Airlines During World War II

During World War II, airlines worked closely with the military to further the war effort by transporting people and materiel. The airlines were well-prepared to play their part in the war effort — plans for their wartime mobilization had been drafted in 1937 by Edgar Gorrell of the industry’s Air Transport Association. 

When the United States entered World War II four years later, the plan was put into action, and the airlines immediately began working closely with the military to coordinate the transport of aircraft, cargo, and personnel throughout the country and around the world.

TWA transferred its entire fleet of five Boeing 307s, along with their flight crews, to the ATC. The airline opened regular transatlantic service in 1942.

Two hundred of the nation’s 360 airliners – particularly the superlative Douglas DC-3s - were drafted for the war effort and placed under the control of the Air Transport Command (ATC). The ATC was formed in June 1942 at the order of U.S. Army Air Forces leader Gen. Henry H. “Hap” Arnold, who wanted to unify civilian and military air transport operations. Airline pilots and flight crew, many of whom were reserve officers in the military, were also called into the ATC and joined their military counterparts. The airline pilots possessed critical knowledge and experience in how to operate a regularly scheduled service over long distances. The ATC was organized by Gen. Robert Olds and later Gen. Harold George. They benefited immensely from the experience of American Airlines president Maj. Gen. C. R. Smith, who served as executive officer.

The ATC functioned as an enormous international airline, combining the efforts of the Ferry Command, which moved combat aircraft around the world, and the Air Service Command, which moved cargo and personnel.

The ATC’s Ferrying Division, which included the famous Women Airforce Service Pilots (WASP), replaced the Army Air Forces Ferrying Command and delivered newly-built aircraft from their factories to training bases or ports of embarkation. From there, the aircraft were flown to overseas destinations including war zones.

The ATC’s Air Transportation Division quickly established a vast national and international route network. The ATC built chains of airfields with concrete runways around the world so that heavy transports could operate anywhere. The first major route opened in 1942 to Brazil and across the south Atlantic to Africa and the Middle East, flying much needed weapons, ammunition, and supplies to the British and other Allied forces who were fighting the German Afrika Corps. 

In 1943, the ATC opened regular service across the north Atlantic, despite treacherous weather conditions, to support the operations of the Eighth Air Force and the huge Allied build-up to the D-Day invasion of June 6, 1944. Following the landings, the ATC supported the Allied advances in western Europe and Italy, delivering supplies and evacuating the most severely wounded. During the liberation of France, they carried almost 3,600 pounds of whole blood into Paris to treat wounded combatants.

The Air Transport Command directly supported Allied operations in the Pacific, reinforcing Australia while supporting America’s advance through the central and southwest Pacific, particularly resupplying the Boeing B-29s in the Marianas, as the 20th Air Force opened its devastating bombing attacks on the Japanese mainland beginning in late 1944.

Douglas C-54

The Douglas C-54 became the backbone of the ATC, with its excellent range and reliability.  It could carry up to 10,000 lbs of cargo, two and a half times more than the Douglas C-47.

Perhaps the ATC’s greatest feat was in the China-Burma-India theater. Using C-47s, larger Curtiss C-46s, four engine Consolidated C-87s, and Douglas C-54s, the ATC flew from bases in India across the treacherous “Hump” of the Himalayan Mountains, fighting unpredictable weather and with no navigation aids, to reinforce Nationalist Chinese and American forces solely by air, as the Japanese had cut off all land and sea routes used by the beleaguered Chinese forces. From July 1942 until December 1945, the ATC delivered 650,000 tons of desperately-needed cargo. The cost was high and 549 aircraft and 1,649 crew members were lost. But China did not fall. Although the ATC was theoretically a non-combat organization, President Roosevelt awarded them the Distinguished Unit Citation for their herculean accomplishment. 

By the end of the war, the ATC operated a huge fleet of 3,700 aircraft with 209,000 military and 104,000 civilian personnel. In its last full month of operation (July 1945) alone, the ATC delivered 100,000 tons of cargo and transported 275,000 high-value passengers, particularly VIPs and wounded servicemen, with most on overseas flights.

The Air Transport Command lasted until June 1, 1948, after the formation of the U.S. Air Force. At that time, it was merged into the comparable, though smaller, Naval Air Transport Service, to create the Military Air Transport Service. This unified America’s airlift capability in time to confront another challenge, the Berlin Airlift. But that is another story.
