Van Anden 1911 Biplane
In 1911 Frank Van Anden built a single place, open cockpit biplane, powered by a 50hp Harriman pusher engine.
VAMP (Van Dersarl Motor Products) Aircraft Co CV
The 1931 VAMP CV was a single place open cockpit biplane with a 70hp VAMP-designed and -built motor. It was registered N579Y.
Wing Ship Technology Corporation Prototype
Wing Ship Technology Corporation prototype is powered by a turboprop and can carry 50 passengers. It has a catamaran-style hull and a reverse delta wing. Its cruising speed, 180kph (110mph), makes it faster than a jetfoil, its principal rival. And the production version will have a range of 1,000km.
Frank Van Dersarl was born August 13, 1895 in Denver. He flew a Bleriot airplane on August 10, 1911 at Sable Airstrip located in Aurora at the junction of Sable Blvd. and the Union Pacific railroad tracks. It was a favored location for early flyers and auto racers. This aircraft was assembled by Frank and his brothers, John and Jules, using plans purchased in France from Bleriot. They were 10 and 12 years old at the time. He also flew a glider, which was built at the age of 12 from a booklet ordered from a London company. It crashed on its first flight.
Pioneer aviator Harry Combs (1913-2003), with only 30 hours of flying under his belt, at the age of 16, decided to build his own aeroplane. With the help of Frank Van Dersarl they completed the construction of a sport bi-plane called the VAMP Bat in 1929. The VAMP Bat had a short life, after flying to Pueblo, Combs lost control of the aircraft on the runway, there were no brakes and only a tailskid, caught in high winds the aircraft flipped on its back. Combs said 'I was hanging upside down inches from the ground. It busted up. I should have known that when you don't have brakes you have to stay on the grass'.

Wacyk-Tyrala WT-1
Stanisław Wacyk and Tadeuz Tyrala designed the high performance sports WT-1 aircraft during 1930 and they largely financed the construction of its fuselage at the Aviation Circle of the Industrial School at Kraków and wings in the workshops of the Kraków Air Regiment. It was completed in the summer of 1931.
The aircraft was an aerodynamically clean cantilever wing monoplane. Its high-mounted, one piece wing was built around two spars, with a plywood covered leading edge and fabric covering. Narrow chord ailerons occupied the whole of the trailing edges.
The WT-1's borrowed 67–73 kW (90–98 hp) de Havilland Gipsy I four cylinder upright inline engine was mounted largely exposed, though with a fairing behind it. The ply-covered fuselage had rounded decking; the fuel tank was in the forward fuselage and its two seat, side-by-side cockpit was behind the wing trailing edge. The fuselage tapered rearwards, with the tailplane mounted on top. A tall triangular fin carried a rounded rudder, which reached down to the keel. Its fixed landing gear was conventional, though details are not known.
An initial first flight was abandoned due to a fuel supply problem. The system was modified and a new fuel pump fitted, after which Stanisław Szubka piloted its first flight, finding the WT-1 hard to fly because of a misplaced centre of gravity (c.g.), and damaging it on landing. After accident repair and c.g. adjustment the WT-1 was flown by Jerzy Bajan. The take-off run was short and performance high, but Bajan found its handling dangerous. At this point the loaned Gipsy engine had to be returned to the Kraków Air Regiment and the development of the WT-1 was abandoned.
