Ellington Field Joint Reserve Base is a joint installation shared by various active component and reserve component military units, as well as aircraft flight operations of the National Aeronautics and Space Administration (NASA) under the aegis of the nearby Johnson Space Center. The host wing for the installation is the Texas Air National Guard's 147th Reconnaissance Wing (147 RW). Opened in 1917, Ellington Field was one of thirty-two Air Service training camps established after the United States entry into World War I. It is named for 1st Lt. Eric Ellington, a U.S. Army aviator who was killed in a plane crash in San Diego, California in 1913. [3]
