Footnote: In 1938, the Civil Aeronautics Act transferred federal responsibilities for non-military aviation from the Bureau of Air Commerce to a new, independent agency, the Civil Aeronautics Authority. The legislation also gave the authority the power to regulate airline fares and to determine the routes that air carriers would serve. In 1940, President Franklin Roosevelt split the authority into two agencies, the Civil Aeronautics Administration (CAA) and the Civil Aeronautics Board (CAB). The CAA was responsible for air traffic control, safety programs, and airway development. The CAB was entrusted with safety rule-making, accident investigation, and economic regulation of the airlines. Although both organizations were part of the Department of Commerce, the CAB functioned independently. After the Second World War began in Europe, the CAA launched the Civilian Pilot Training Program, to provide the nation with more aviators. On the eve of America's entry into the conflict, the agency began to take over operation of airport control towers, a role that eventually became permanent. During the war, the CAA also greatly enlarged its en route air traffic control system. In 1944, the United States hosted a conference in Chicago that led to the establishment of the International Civil Aviation Organization and set the framework for future aviation diplomacy. In the post-war era, the application of radar to air traffic control helped controllers to keep abreast of the postwar boom in air transportation. In 1946, Congress gave the CAA the task of administering a federal-aid airport program aimed exclusively at promoting development of the nation's civil airports.
