Boucheron

   In 1910 L'Aeronaute printed a drawing and accompanying description of a 2-seat biplane with variable-size wings and a waterproof diamond-section fuselage for possible accidental water landings. 2 pusher propellers were mounted on outriggers aft of the wings, which were curved like a gull's. A small biplane elevator cell was set, as on the Voisin, on a curved extension of the fuselage. It is not clear exactly how the variable sized wing arrangement worked - or if in fact the machine was ever built.
