In 1940, President Roosevelt split the CAA into two agencies, the Civil Aeronautics Administration, which went back to the Department of Commerce, and the Civil Aeronautics Board ( CAB). The legislation also expanded the government's role in civil aviation by giving CAA power to regulate airline fares and determine the routes individual carriers served. The legislation established the independent Civil Aeronautics Authority ( CAA), with a three-member Air Safety Board that would conduct accident investigations and recommend ways of preventing accidents. To ensure a federal focus on aviation safety, President Franklin Roosevelt signed the Civil Aeronautics Act in 1938. Four years later, a DC-2 crash killed U.S. A 1931 crash that killed all on board, including popular University of Notre Dame football coach Knute Rockne, elicited public calls for greater federal oversight of aviation safety. While the Department of Commerce worked to improve aviation safety, a number of high profile accidents called the department's oversight responsibilities into question. Although en route ATC became a federal responsibility, local government authorities continued to operate airport towers. Early en route controllers tracked the position of planes using maps and blackboards and little boat-shaped weights that came to be called "shrimp boats." They had no direct radio link with aircraft, but used telephones to stay in touch with airline dispatchers, airway radio operators, and airport traffic controllers. In 1936, the Bureau took over these centers. In one of its first acts, the Bureau encouraged a group of airlines to establish the first air traffic control centers (Newark, New Jersey Cleveland, Ohio and Chicago, Illinois) to provide en route air traffic control. In 1934, the Department of Commerce renamed the Aeronautics Branch the Bureau of Air Commerce to reflect the growing importance of aviation to the nation. MacCracken, Jr., became its first director. A new Aeronautics Branch in the Department of Commerce assumed primary responsibility for aviation oversight, and William P. This landmark legislation charged the Secretary of Commerce with fostering air commerce, issuing and enforcing air traffic rules, licensing pilots, certifying aircraft, establishing airways, and operating and maintaining aids to air navigation. At their urging, the Air Commerce Act was passed in 1926.

Low visibility and night landings were made using bonfires on the field as lighting. Pilots flew 200 to 500 feet above ground so they could navigate by roads and railways. Flying conditions proved difficult since the only navigation devices available to most pilots were magnetic compasses. During World War I, the airplane also proved its effectiveness as a military tool and, with the advent of early airmail service, showed great promise for commercial applications.ĭespite limited post-World War I technical developments, early aviation remained a dangerous business. As a result, the early 20th century witnessed myriad aviation developments as new planes and technologies entered service.
This twelve-second flight led to the development of the first practical airplane in 1905 and launched worldwide efforts to build better flying machines.
The modern age of powered flight began in 1903 when Orville Wright made the first sustained, powered flight on December 17 in a plane he and his brother Wilbur built.
