Ellington Airport — Houston, United States

EFD, Ellington Airport, is a joint-use facility in Houston, Texas, combining military, NASA, and general aviation operations. Home to the Texas Air National Guard's 147th Attack Wing and a NASA facility supporting astronaut flight training, Ellington has deep ties to the Johnson Space Center located nearby. Historically used as a training base since World War I, EFD today handles corporate jets, cargo operations, and government flights alongside its military and space-related missions. Its dual civilian-military character distinguishes it from Houston's larger commercial airports, Bush Intercontinental and Hobby. EFD also occasionally serves as a diversion or backup field for the region, and its unique mix of aerospace history and modern operations makes it a distinctive part of Houston's aviation landscape.
