Waldo Waterman

Waldo Dean Waterman (June 16, 1894 - December 8, 1976) was an inventor and aviation pioneer from San Diego, California. His most notable contributions to aviationwere the first tailless monoplane (the precursor to the flying wing), the first aircraft with modern tricycle landing gear and the first successful flying car.

Waterman built his first aircraft, a biplane hang glider, in 1909 while still in high school. He successfully flew the biplane hang glider on a slope near his home and by auto-tow. He then took-on a partner to help build a powered aircraft that he entered in the first Dominguez Air Meet in January 1910. The aircraft was not completed in time for the meet. However, he began testing the aircraft on North Island. It was under-powered and required an auto-tow assist to get airborne. He flew the aircraft with some success but crashed, breaking both ankles.

In 1911, Glenn Curtiss moved his winter headquarters to North Island and Waterman attached himself to the Curtiss camp. In early 1912 the US Navy moved its three aircraft to Curtiss' testing station. By this time Waterman was a fixture at the station and was a frequent ride-along.

In 1912 Waterman entered the University of California as a student of mechanical engineering. When World War I broke out, and after being rejected from military service because of his broken ankles and flat feet, he became head of the Department of Theory of Flight, School of Military Aeronautics at the University of California. Later he became Chief Engineer at the U.S. Aircraft Corporation and remained to liquidate the company at the end of the war. With some assets purchased from the U.S. Aircraft Corporation Waterman moved to Santa Monica where he established the Waterman Aircraft Manufacturing Company. However, he was forced out of business when the U.S. Army began dumping war-surplus aircraft on the civilian market for a tiny fraction of what Waterman could sell his custom aircraft for.

In 1929 Waterman built the first tailless monoplane. With the tailless "Whatsit" he also introduced modern tricycle landing gear. Some consider the "Whatsit" to be the first flying wing. It was certainly a step in the development of the flying wing but had a truncated fuselage. It was usually, more correctly, called a tailless airplane. A development of the "Whatsit" was the high-wing Aeroplane.

Besides his "Whatsit" innovative aircraft design, in 1930 - Waterman design and built a flexible wing aircraft that was a low wing monoplane that could elevate and lower its wings during flight for shorter takeoffs, increased flight speed, and slower landing speeds according to the designer in its debut at the National Air races in Chicago. In addition to the wing design, he also placed the landing gears not under the fuselage but outwards under the wings.

At North Island, while experimenting with the Navy's flying boats, Glenn Curtiss is known to have talked about the possibility of a flying car. In 1917 He built a flying car he called the "Autoplane". The "Autoplane" never flew but was exhibited at the Pan-American Aeronautic Exposition in New York City's Grand Central Palace. Waterman was certainly inspired by Curtiss and 20 years later made the first successful flying car. The Waterman Aerobile was based on the "Aeroplane". It was a high-wing monoplane, with detachable wings and was powered by a Studebaker engine. Five "Aerobiles" were built. Three "Aerobiles" attempted a flight from Santa Monica to Ohio but one had to turn back after only reaching Arizona. The other two finished the flight. "Aerobile" No. 6 (No. 5 was never completed) is on display at the Steven F. Udvar-Hazy Center (Smithsonian Air and Space museum extension in Dulles, Virginia)

In the 1960s, Waterman built and flew his last aircraft. The "Early Bird" was based on the original Curtiss Pusher. The "Chevybird" was a similar monoplane powered by a Corvair engine. In early 1970s Waterman directed the construction of a replica of his youth's biplane hang glider in conjunction with Michael Riggs of Seagull Aircraft in a building owned by Waterman in Santa Monica, California, a building leased to Seagull Aircraft and Self-Soar Association. Waterman donated $100 to Joe Faust of Self-Soar Association for the purpose of forwarding the publishing of hang glider information in "Low & Slow" periodical where notes about Waldo Waterman's final aircraft construction project were noted.
