Ellington Airport is a public airport located approximately 15 miles southeast of downtown Houston, Texas. Originally established as a military training field during World War I, it has served various military and civilian purposes throughout its long history. Today, Ellington is jointly operated by the City of Houston and functions as a base for the Texas Air National Guard, NASA's aircraft operations, and general aviation. It is home to the 147th Attack Wing of the Texas Air National Guard and supports NASA Johnson Space Center flight operations. The airport has been designated as a spaceport by the FAA and is part of Houston's long-term plans to develop commercial space launch activities. It handles no scheduled commercial airline service but supports military, government, corporate, and charter operations.
