軍事航空
Military aviation appeared in World War I when aircraft were initially used to spot enemy troop concentrations, field gun positions and movements. Early aerial combat consisted of aviators shooting at one another with hand-held weapons. The first recorded aircraft to be shot down by another aircraft, which occurred on October 5, 1914, was a German Aviatik. The pilot, Feldwebel Wilhelm Schlichting, was shot with a carbine wielded by observer Louis Quenault, who was riding in a Voisin Type 3 piloted by French Sergeant Joseph Frantz.
