Built in the late 1960s as a stretched version of the C-141A, the Lockheed L-300 was Lockheed's bid for a commercial cargo aircraft. Though it never entered production, the prototype was donated to NASA and became the Kuiper Airborne Observatory in 1974. With a 36-inch telescope mounted inside, it helped discover Uranus's rings, detect Pluto's atmosphere, and study Supernova 1987A.
