The Boeing VC-25 is the designation of a United States Air Force passenger transportation aircraft, a military version of the Boeing 747 airliner. The A-model is the only variant of the VC-25. The VC-25 is most famous for its role as Air Force One, the call sign of any U.S. Air Force aircraft carrying the President of the United States. The two aircraft currently in U.S. service are highly modified versions of Boeing's 747-200B, with tail numbers 28000 and 29000. Although the Air Force One designation technically applies to the aircraft only while the President is aboard, the term is commonly applied to the VC-25s more generally. They often operate in conjunction with Marine One helicopters that ferry the President to airports in circumstances where a vehicle motorcade would be inappropriate. Wikipedia [ - ]
