Landeroin et Robert

  Introduced at the 1914 Concours de Securite, this bizarre machine was meant to be automatically stable. It was built at Pierre Levasseur's factory around what looked like a Morane-Saulnier fuselage, at the rear end of which was set a trapezoidal rudder and a semicircular elevator on each side. These were the only familiar features. The rest was a tandem monoplane with one pair of straight rectangular wings mounted far back at the top of the fuselage; the front pair was swept back from a straight center-section which was mounted precariously out in front of the engine and propeller, the whole thing braced with curved struts over and around the propeller, down to the undercarriage; one ran all the way back over the top to the tailpost. Ailerons were set into the inner sections of the trailing edges of the front wings. A 3-skid addition was made to the undercarriage.
