Nellis Air Force Base

Nellis Air Force Base is a United States Air Force installation in southern Nevada with military schools and more squadrons than any other USAF base. Nellis hosts air combat exercises such as Exercise Red Flag and close air support exercises such as Green Flag-West flown in "Military Operations Area airspace", associated with the nearby Nevada Test and Training Range . The base also has the Combined Air and Space Operations Center-Nellis.

After World War I, Nevada and other western inland states were surveyed by Capt. Lowell H. Smith and Sgt. William B. Whitefield for landing sites, and by "mid-1925 the Air Service possessed information on nearly thirty-five hundred landing places, including more than twenty-eight hundred emergency landing areas, in the United States." The 1929 airfield north of Las Vegas—operated by the 1925 Western Air Express for Contract Air Mail Route #4, LA-to-SLC—was used by the Army Air Corps in the 1930s for training flights . After the Invasion of Poland in 1939, the "western site board" had located a southern Nevada area "near Tonopah, Nev" by April 1940 for a military range, and in October 1940, Air Corps Major David Schlatter surveyed the southwest United States for a military airfield. "The 60 × 90 mile area at Tonopah was transferred to the War Department on 29 October 1940" by Executive Order 8578.
