From the 1950s through the 1970s, Ellington Field was utilized for pilot and navigator training for the active Air Force, Air Force Reserve, Air National Guard, and Naval Air Reserve, Marine Air Reserve, and foreign students.
NASA established its facilities at Ellington as its base for astronaut flight proficiency training and specialized aircraft training in the early 1960s because of its proximity to the newly constructed Manned Spacecraft Center. The T-38 Talon (T-38N) is the primary jet aircraft used for astronaut training at Ellington. From 1967, Ellington was used for the Apollo program's Lunar Landing Training Vehicle. Today, most of NASA's aircraft based at the Johnson Space (Manned Spacecraft) Center are kept and maintained at the base.
