NATURA ornithopter (N.R. Gordon)

   This machine was reported in The Car Illustrated as being at the 1910 Aero Show, but was ignored by the aviation press. The illustration published was of a small flapping wing monoplane. The wings, which were heavily cambered and gull-shaped, were mounted at the top of a tubular structure. The operator was seated below and pedaled to provide the motion, through a system of levers. An extension of the chassis, which was mounted on three wheels, carried a fixed horizontal tail surface.
