Air Force One is the official air traffic control call sign for a United States Air Force aircraft carrying the president of the United States. In common parlance, the term is used to denote U.S. Air Force aircraft modified and used to transport the president. The aircraft are prominent symbols of the American presidency and its power.
The idea of designating specific military aircraft to transport the President arose in 1943, when officials of the United States Army Air Forces, the predecessor to the U.S. Air Force, became concerned about using commercial airlines for presidential travel. A C-87 Liberator Express was reconfigured for use as the first dedicated VIP-and-presidential transport aircraft and named Guess Where II, but the Secret Service rejected it because of its safety record.
