Aviation in the United States was unregulated until the
Air Commerce Act became law in 1926. The Act created an Aeronautic Branch within the
United States Department of Commerce with regulatory powers over civil aviation. Among the functions the Aeronautic Branch performed were
pilot testing and licensing, issuing aircraft
airworthiness certificates, establishing and enforcing safety regulations. The agency was also responsible for establishing airways and operating and maintaining aids to air navigation, in addition to investigating accidents and incidents. In 1934, the Aeronautics Branch was renamed the
Bureau of Air Commerce. In 1936 the Bureau took over air traffic control centers previously operated by
commercial airlines, and began to expand the
air traffic control system. In 1938, the Civil Aeronautics Act moved oversight of non-military aviation into a new, independent agency, the
Civil Aeronautics Authority. The new agency gained the authority the power to regulate fares and routes for commercial airlines. Another change followed in 1940, with CAA's authority being split. The CAA continued to have authority for air traffic control, safety, and promotion of civil aviation. The new
Civil Aeronautics Board (CAB) was established and had responsibility for accident investigation, as well as regulation of safety of civil aviation and pricing of commercial aviation. A boom in the 1950s of aircraft technology and the airline industry crowded American airspace, and the regulation of air traffic was considered antiquated. In 1956, President
Dwight D. Eisenhower appointed
Edward Peck Curtis as Special Assistant for Aviation. Later that year, Curtis was named by Eisenhower to head a commission to study the dramatic increase in airline traffic and to propose ways to deal with airplane traffic jams at airports. From that commission came a proposal to create a new Federal aviation agency that would replace the Civil Aeronautics Administration and the Civil Aeronautics Board to consolidate air operations, modernize the airways and to make and enforce safety rules. ==Mid-air collisions spur change==
