Boeing VC-25

Boeing VC-25

It is a military version of the Boeing 747 aircraft specially modified by the United States Air Force (USAF) for presidential transport, commonly referred to as "Air Force One", which is the call sign for any U.S. Air Force aircraft carrying the President of the United States. At present, there are only two aircraft of this model in service, which are highly modified Boeing 747-200B, model VC-25A, with tail numbers 28000 and 29000 respectively. Although technically, the term 'Air Force One' is only applicable when the President is on board the aircraft, it is commonly used to refer to the VC-25 aircraft.
