History

After the surprise attack by the Japanese on Pearl Harbor, Hawaii, in December 1941, the military decided that an inland training location was preferred, to the current Ryan School of Aeronautics in San Diego, California, founded by aviation pioneer T. Claude Ryan and

was chosen as the site. Ground was broken in June 1942 for the new Ryan School of Aeronautics of Arizona under the direction of the

U.S. Army Air Forces The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II ...

, located about 15 miles southwest of Tucson, along the Ajo Highway. By August 1942, the institution with its half-completed buildings and roofless offices, was training aviators in the Ryan P-22 aircraft, which functioned surprisingly well in the heat, wind and dust storms, although crashes did occur at the school, at times, leading to death in certain incidents. By July 1943, when T. Claude Ryan, the president of the school, returned the following year, Ryan Airfield had been completed. By this time the airfield had electricity, plumbing and air conditioning. The ground was covered with asphalt to hold the desert dust. It also had barracks and a PX. Military flight training at Ryan ceased in 1944 and the property was conveyed to the State of Arizona in 1948. Currently owned by the City of Tucson, Ryan is operated by the Tucson Airport Authority under an agreement which expires in 2054. An air traffic control tower was constructed at Ryan in 1993. The airport was added to the Contract Tower Program in 1996. In September 2004, the tower staff completed the one millionth operation without an error. In May 2010, the tower staff achieved two million operations without an error. Significant infrastructure improvements and major maintenance projects are accomplished continuously, as is private and commercial hangar construction. TowerKRYN
