First U.S. Aerial Victory
On February 5, 1918, US pilot Stephen W. Thompson shot down a German aircraft, making him the first person in the American military to shoot down an enemy plane.
Born in Missouri, Thompson was a senior at the University of Missouri when the US entered World War I. His school then announced that seniors that joined the military before graduation would receive their diplomas in June. So Thompson enlisted in the Army and went for training at the Coast Artillery Corps. On the train there, he saw an airplane flying overhead for the first time.
