From 1975-1995 NASA's Kuiper Airborne Observatory (KAO) was operated as the world's only airborne telescope devoted exclusively to astronomical research. KAO was named after the astronomer Gerard P. Kuiper. Carrying a 36-inch reflecting telescope, KAO was a converted C-141 military cargo plane with a 160-foot wingspan. Flying at altitudes of 41,000 to 45,000 feet, above 99 percent of the Earth's infrared-absorbing water vapor, KAO was capable of conducting infrared astronomy. KAO ended its long service to astronomy in October 1995, so that work could begin on its successor, the Stratospheric Observatory for Infrared Astronomy (SOFIA).
