Lemaitre, Maucourt, et Legrand

   Associated with Maucourt, Henri Lemaitre and Gaston Legrand built a monoplane they called Hirondelle (swallow); some sources report 3 separate Hirondelles, and there do appear variations from picture to picture. But others report a Lemaitre monoplane uncompleted at Juvisy in May 1910, a Lemaitre et Legrand flying at La Vidamee (Chantilly) early in 1911, another finished in July, and still another flying at La Vidamee at the end of the year.
   Whether one or 3, the basic design had a flat-decked fuselage of triangular section. The wings warped, and were set on the deck ahead of the cockpit; the trailing edges were longer than the leading edges. The machine stood on a 4-legged undercarriage with 2 wheels and skids, and a pyramidal skid in front of the rectangular tailplane and its triangular elevators. A semicircular rudder was fitted to a triangular fin. A 40 hp 4-cylinder inline Labor-Aviation motor drove a 2-bladed Normale propeller; the radiators were attached to the forward sides of the fuselage, which was covered only on the bottom from the pilot seat aft. Construction was of both wood and metal.
