The Lockheed VC121-E Super Constellation served as Eisenhower’s personal aircraft between 1954 and 1961, providing non-stop intercontinental travel for the first time. It was christened by First Lady Mamie Eisenhower to represent the Colorado State Flower. Columbine I served Eisenhower during WWII, and Columbine II was his first presidential aircraft. Columbine III was retired when he left office.
While Columbine III graces the Presidential Galleries in the National Museum of the USAF, Columbine II withers away in the arid desserts of Arizona Boneyard.
