Mountain Valley Airport is a privately owned public-use airport located two nautical miles (4 km) southeast of the central business district of Tehachapi, in Kern County, California, United States.The airport is used for glider operations and training. It was established for its close proximity to various advantageous lift effects for soaring where the Sierra Nevada Mountains, Tehachapi Mountains and the Mojave Desert meet.The Skylark North Glider School performs glider flight training for civilians as well as for the US Air Force Test Pilot School (from Edwards AFB), the National Test Pilot School (from the Mojave Air & Space Port), NASA and others. Due to the ongoing training contract with the US Air Force Test Pilot School, probably most or nearly all NASA Space Shuttle pilots who came from the Air Force have received glider training at Mountain Valley Airport.
