    Early attempts to provide a semblance of air traffic control were based on simple "rules of the road" resulting from the European sponsored International Convention for Air Navigation (1919). The United States formulated its first regulations relating to air traffic following the passage of the Air Commerce Act of 1926. By 1930, radio equipped airport traffic control towers were being established ... View full abstract»
