On May 21, 1958, Senator A. S. "Mike" Monroney (D-OK) introduced a bill to create an independent Federal Aviation Agency to provide for the safe and efficient use of national airspace. Two months later, on August 23, 1958, the President signed the Federal Aviation Act, which transferred the Civil Aeronautics Authority's functions to a new independent Federal Aviation Agency responsible for civil aviation safety. Although the Federal Aviation Agency technically came into existence with the passage of the act, it actually assumed its functions in stages. Under the provisions of the act, the Federal Aviation Agency would begin operations 60 days after the appointment of the first Federal Aviation Agency Administrator. On November 1, 1958, retired Air Force General Elwood "Pete" Quesada became the first Federal Aviation Agency Administrator. Sixty days later, on December 31, the Federal Aviation Agency began operations.
