"Technically, Air Force One is used to describe any Air Force aircraft carrying the President — but since the middle of the 20th century, it has been standard practice to refer to specific planes that are equipped to transport the Commander-in-Chief. Today, this name refers to one of two highly customized Boeing 747-200B series aircraft, which carry the tail codes 28000 and 29000. The Air Force designation for the aircraft is VC-25A."
