The Blériot XI, or Blériot Type XI, is a light monoplane produced between 1909 and 1931 by the French aircraft manufacturer Blériot Aéronautique. Louis Blériot, its inventor, goes down in history for having made the first crossing of the Channel on July 25, 1909, traveling 38 km in 37 minutes at an average speed of 61.6 km/h. Its front-engine, rear-tail monoplane configuration, very different from the rear-propeller canard biplane configuration of Wright aircraft, eventually became the most common. Blériot thought it would be his last plane, because he was ruined by his inventions1. The Blériot XI is one of the first mass-produced aircraft, sold in hundreds of copies, in four categories: training, tourism, competition and military.
