During the early days of World War I, both the French and British used two-seat Bleriots for reconnaissance behind German lines. By 1915, however, more advanced aircraft relegated the Bleriot to a training role.

The Bleriot monoplane first achieved fame in 1909 when its designer, Louis Bleriot of France, piloted one on the first flight across the English Channel.
