Archie League, American air traffic controller (born 1907)
Archie League
Archie William League is generally considered the first air traffic controller in the United States. League had been a licensed pilot, and licensed engine and aircraft mechanic. He had barnstormed around in Missouri and Illinois with his "flying circus," prior to St. Louis hiring him as the first U.S. air traffic controller in 1929. He was stationed at the airfield in St. Louis, Missouri. Before the installation of a radio tower, he was a flagman who directed traffic via flags. His first "control tower" consisted of a wheelbarrow on which he mounted a beach umbrella for the summer heat. In it he carried a beach chair, his lunch, water, a notepad and a pair of signal flags to direct the aircraft. He used a checkered flag to indicate to the pilot "GO", i.e. proceed, or a red flag to indicate the pilot should "HOLD" their position. He kept warm out on the field in the winters by wearing a padded flying suit. When a radio tower was installed in the early 1930s, he became the airport's first radio controller.
