Air Force One instance of call sign
SAM 27000
SAM 26000 was replaced in December 1972 by another VC-137C, Special Air Mission 27000, although SAM 26000 was relegated to non-presidential VIP status (and repainted without the darker blue cap and cheatline), it served as a backup to SAM 27000 until it was finally retired in 1998.In June 1974, while President Nixon was on his way to a scheduled stop in Syria, Syrian fighter jets intercepted Air Force One to act as escorts. The crew was not informed in advance, so took evasive action including a dive.After announcing his intention to resign the presidency, Nixon boarded SAM 27000 (with call sign "Air Force One") to travel to California. Colonel Ralph Albertazzie, then pilot of Air Force One, recounted that after Gerald Ford was sworn in as president, the plane had to be redesignated as SAM 27000, indicating no president was on board the aircraft. Over Jefferson City, Missouri, Albertazzie radioed: "Kansas City, this was Air Force One. Will you change our call sign to Sierra Alpha Mike (SAM) 27000?" Back came the reply: "Roger, Sierra Alpha Mike 27000. Good luck to the President."Other presidential aircraft
During the Johnson Administration, the United States Air Force acquired a Beechcraft King Air B90 which was designated VC-6A (66-7943). The aircraft was used to transport President Johnson between Bergstrom Air Force Base and his family ranch near Johnson City, Texas, and was used at least once to transport the President to Princeton, New Jersey. It was referred to as Lady Bird's airplane and later in its service life featured a basic color scheme similar to civilian aircraft. When the President was aboard, the aircraft used the call sign Air Force One.United Airlines is the only commercial airline to have operated Executive One, the call sign given to a civilian flight on which the US president is aboard. On 26 December 1973, President Richard Nixon and his family flew as commercial passengers on a United DC-10 from Washington Dulles to Los Angeles International Airport. His staff explained that this was done to conserve fuel by not having to fly the usual Boeing 707 Air Force aircraft.
