Brown Field is 1.5 miles north of the US/Mexico border in the Otay Mesa Community of the City of San Diego. The airport, originally named East Field in honor of Army Major Whitten J. East, opened in 1918 when the U.S. Army established an aerial gunnery and aerobatics school to relieve congestion at North Island. Major East completed flight training at the Army Signal Corps Station, Rockwell Field on North Island before flying over the front lines in France during World War I. He was killed in an auto accident in 1918 while in command of Mitchel Field in New York at the age of 25. From 1918 to 1919, pilots flying the Curtiss JN-4D Jenny trained at East Field. After World War I the military maintained control of East Field for touch and go landings and radio controlled target drone experiments.
