Air Force One is the official air traffic control designated 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 and a metonym for the primary presidential aircraft, VC-25, although it can be used to refer to any Air Force aircraft the president travels on.

The idea of designating specific military aircraft to transport the president arose during World War II when military advisors in the War Department were concerned about the risk of using commercial airlines for presidential travel. A C-54 Skymaster was then converted for presidential use; dubbed the Sacred Cow, it carried President Franklin D. Roosevelt to the Yalta Conference in February 1945 and was used for another two years by President Harry S. Truman.

The "Air Force One" call sign was created in 1953, after a Lockheed Constellation carrying President Dwight D. Eisenhower entered the same airspace as a commercial airline flight using the same flight number. Since the introduction of SAM 26000 in 1962, the primary presidential aircraft has carried the distinctive livery designed by Raymond Loewy.

Other aircraft designated as Air Force One have included another Lockheed Constellation, Columbine III, three Boeing 707s, introduced in the 1960s and 1970s, and the current Boeing VC-25As. Since 1990, the presidential fleet has consisted of two highly customized Boeing 747-200B (VC-25A) aircraft.

On 11 October 1910, Theodore Roosevelt became the first US president to fly in an aircraft, an early Wright Flyer from Kinloch Field near St. Louis, Missouri. He was no longer in office at the time, having been succeeded by William Howard Taft. The record-making occasion was a brief overflight of the crowd at a county fair but was nonetheless the beginning of presidential air travel.

First presidential aircraft

Concerned about relying upon commercial airlines to transport the president, officials of the United States Army Air Forces, the predecessor to the US Air Force, ordered the conversion of a military aircraft to accommodate the special needs of the commander-in-chief. The first dedicated aircraft proposed for presidential use was a C-87A VIP transport aircraft. This aircraft, number 41-24159, was modified in 1943 for use as a presidential VIP transport, the Guess Where II, intended to carry President Franklin D. Roosevelt on international trips. Had it been accepted, it would have been the first aircraft to be used in presidential service. After a review of the C-87's highly controversial safety record in service, the Secret Service flatly refused to approve the Guess Where II for presidential carriage. As the C-87 was a derivative of the Consolidated B-24 Liberator bomber, it presented strong offensive impressions to enemy fighter aircraft as well as foreign destinations visited, an issue not present with airplanes that were used purely for transport. The Guess Where II was used to transport senior members of the Roosevelt administration on various trips. In March 1944, it transported Eleanor Roosevelt on a goodwill tour of several Latin American countries. The C-87 was scrapped in 1945.

The Secret Service subsequently reconfigured a Douglas C-54 Skymaster for presidential transport duty. The VC-54C aircraft, nicknamed the Sacred Cow, included a sleeping area, radiotelephone, and retractable battery powered elevator to lift Roosevelt in his wheelchair. As modified, the VC-54C was used by President Roosevelt only once before his death, on his trip to the Yalta Conference in February 1945.

Toward the end of Eisenhower's second term, Secretary of State John Foster Dulles commented that Soviet Premier Nikita Khrushchev and other senior Soviet officials had begun using the technologically advanced Tupolev Tu-114 aircraft for their travels, and it was no longer dignified for the president to fly in a propeller-driven aircraft. This paved the way for the Air Force's initial procurement of three Boeing 707-120 (VC-137A) jet aircraft, designated SAM (Special Air Missions) 970, 971 and 972.

The high-speed jet technology built into these aircraft enabled presidents from Eisenhower through Nixon to travel long distances more quickly for face-to-face meetings with world leaders. Then-Vice President Richard Nixon first used a VC-137A on his visit to Russia in July 1959 for the Kitchen Debates. The following month, Eisenhower became the first president to fly via jet airplane when he used SAM 970, nicknamed "Queenie", to meet German Chancellor Konrad Adenauer. During Eisenhower's "Flight to Peace" goodwill tour in December 1959, he visited 11 Asian nations, flying 22,000 miles (35,000 km) in 19 days, twice as fast as he could have covered that distance in one of the Columbines.

SAM 970 to SAM 972 would be removed from the presidential role with the early-1960s arrival of the specially built VC-137C designated SAM 26000. The older planes would be repainted in the Loewy secondary livery designed for Air Force Two and other non-presidential VIP aircraft. SAM 970 is now on display at The Museum of Flight in Seattle, Washington. SAM 971, best remembered for returning the Americans held during the Iran hostage crisis in 1981, is on display at the Pima Air and Space Museum in Tucson, Arizona. SAM 972 was scrapped in October 1996.

The new VC-137C was not yet modified for presidential service when John F. Kennedy took office in 1961. On the recommendation of his wife, Jacqueline Kennedy, he contacted the French-born American industrial designer Raymond Loewy for help in designing new livery and interiors for the VC-137C.

Loewy, who had seen SAM 970, complained to a friend in the White House that it "had a garish orange nose and looked too much like a military plane", Air Force One historian and former Smithsonian curator Von Hardesty told CNN. He offered Kennedy his design consultation services free of charge.

Kennedy chose a red-and-gold design from one of Loewy's initial concept sketches, and asked him to render the design all in blue. Loewy also drew inspiration from the first printed copy of the United States Declaration of Independence, suggesting the widely spaced and upper case "United States of America" legend in Caslon typeface. He chose to expose the polished aluminum fuselage on the bottom side and used two blues, steel blue associated with the early republic and the presidency, and a more contemporary water blue to represent an America both rooted in the past and flying inexorably into the future. The presidential seal was added to both sides of the fuselage near the nose and a large American flag was painted on the tail. Loewy's work won immediate praise from the president and the press. 

The cheatline suggested a sleek and horizontal image that mirrored America's Jet Age optimism and prosperity of the era, and today signifies its legacy and tradition.

Loewy's VC-137C livery was adapted for the larger VC-25A when it entered service in 1990, and the secondary variation (without the darker blue cheatline and cap over the cockpit) is still in use on USAF C-40, C-37, C-32, and C-20 aircraft in standard (non-presidential) VIP configurations. The presidential paint scheme can also be seen on Union Pacific 4141, the locomotive used in George H. W. Bush's funeral train.

Under John F. Kennedy, presidential air travel entered the jet age. Although he could use the Eisenhower-era jets for trips to Canada, France, Austria, and the United Kingdom, when he came into office, his primary aircraft domestically was still a prop powered Douglas VC-118A Liftmaster. In October 1962, the modified long-range Boeing VC-137C Stratoliner SAM 26000, featuring livery designed by Loewy would be delivered, and immediately became an important element of the Kennedy administration's brand.

SAM 26000 was in service from 1962 to 1998, serving Presidents Kennedy to Clinton. On 22 November 1963, SAM 26000 carried President Kennedy to Dallas, Texas, where it served as the backdrop as the Kennedys greeted well-wishers at Dallas's Love Field. Later that afternoon, Kennedy was assassinated, and Vice President Lyndon Johnson assumed the office of President and took the oath of office aboard SAM 26000. On Johnson's orders, the plane carried Kennedy's body back to Washington. A decade later, SAM 26000 took Johnson's body home to Texas after his state funeral in Washington.

The U.S. Air Force usually does not have fighter aircraft escort the presidential aircraft over the United States but it has occurred. The first instance came during the state funeral of John F. Kennedy when it was followed by 50 fighters (20 Navy and 30 Air Force), representing the states of the union.

Johnson used SAM 26000 to travel extensively domestically and to visit troops in South Vietnam during the Vietnam War. SAM 26000 served President Nixon on several groundbreaking overseas voyages, including his famous visit to the People's Republic of China in February 1972 and his trip to the Soviet Union later that year, both firsts for an American president. Nixon dubbed the plane the "Spirit of '76" in honor of the forthcoming bicentennial of the United States; that logo was painted on both sides of the plane's nose.

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.”

Though Ronald Reagan's two terms as president saw no major changes to Air Force One, the manufacture of the presidential aircraft version of the 747 began during his presidency. The USAF issued a Request For Proposal in 1985 for two wide-body aircraft with a minimum of three engines and an unrefueled range of 6,000 miles (9,700 km). Boeing with the 747 and McDonnell Douglas with the DC-10 submitted proposals, and the Reagan Administration ordered two identical 747s to replace the aging 707 VC-137 variants he used. The interior designs, drawn up by First Lady Nancy Reagan, were reminiscent of the American Southwest.
