The U-4B, an Air Force version of the L-26 Aero Commander, was used by President Dwight D. Eisenhower from 1956 to 1960 for short trips. It was the smallest "Air Force One," and the first Presidential aircraft to have only two engines. The U-4B was also the first Presidential aircraft to carry the familiar blue and white paint scheme. After President Eisenhower left office the aircraft was used for transporting high-ranking government officials. On October 1, 1969 it was transferred to the Air Force Academy where it was used for cadet parachute training and the Academy's skydiving team. In November 1977 the U-4B was sent to the Nebraska Civil Air Patrol. It was obtained by the Air Force Museum from a private owner in 1996 and placed on display in July 1997.
