In 1928 George White built a single place, open cockpit high wing monoplane ornithopter. The wingtips moved 17′ when the pedals were pushed 14″. With “a smaller craft,” 14 flights were made with up to 140 yards distance and 7′ height.

White Der Jager D.IX
Designed by Lou Stolp & Marshall White, though modeled after World War I fighters, the Der Jager is not a replica. Its builder, Marshall White, patterned the wing shape after that of the German Albatross, the tail assembly after that of the Fokker D-7 and the gear after that of the Focke-Wulf “Strosser”. The frameworks of the fuselage and the tail group are of welded steel tube, fabric covered. The wings are wood with no flaps. The pro¬totype was fitted with a 115-hp Lycoming, but the airplane is so light that anything down to the Volkswagen 1600 engine will fly it nicely.
The prototype, N3610, first flew on 7 September 1968.

Whisper Aircraft Whisper motorglider
The Whisper motorglider is equally at home soaring in rising air as a glider, or motoring long distances as a roomy, yet fast touring aircraft.
The Whisper was designed for the homebuilder. Every component has been optimized to ease the task of the homebuilder. The aircraft can be built from a “basic package” or from a “fast build package” depending on how many hours the builder wishes to spend on the project. Components not supplied in these packages can be manufactured by the builder or ordered from the factory. All hardware is ordered directly from Aircraft Spruce & Specialty by the builder.
The Whisper can be built with a wingspan of 16m (52.5′) or 12m (39.4′) to suit individual requirements. With the longer wing the aircraft has a glide ratio of 28:1 and a minimum sink rate of 200fpm which makes it a very capable glider. The 21USG fuel tank and the 115MPG cruise speed also make the aircraft capable of very long powered flights. The 4’2″ wide cabin allows for very comfortable side by side seating. The aircraft can be built with conventional or nose wheel undercarriage.
The aircraft structure is fiberglass and the wing has been tested to an ultimate load of 10.6g. Engine options are VW2100, Jabiru 2200/3300, Rotax 912/S

Wildeblood Triplane
Of 46 foot span and fitted with a 35 hp JAP radial motor, this triplane was designed by Henry Seddon Wildeblood and built by the Upper India Motor Company of Lucknow, India, in August 1911.
Wildeblood, Henry Seddon
Wildeblood was superintending engineer of the Indian Public Works Department of Mount Abu, Rajputana, India, circa 1911.
He studied the flight of birds extensively and on the results of his findings designed models and full-size aircraft which incorporated flexible receding wing-tips, with outer edges rigid in imitation of the feathers of a bird’s wing.
