Breguet LE explained

The Breguet LE or Breguet Laboratoire Eiffel was a prototype French monoplane fighter built during World War I. The sole aircraft completed crashed on its second flight in 1918, killing the pilot. The program was terminated and the two other aircraft under construction with more powerful engines were broken up.
