General Aircraft Corp GAC-100
General Aircraft Corporation announced plans in 1969 for a 36- seat STOL transport, the GAC-100, powered by four Pratt & Whitney PT6A-40 turboprop engines.
General Aircraft Corp / GAC G1-80 Skyfarer
The General Aircraft Corporation was established to build an aircraft designed by Doctor Otto C. Koppen from the Massachusetts Institute of Technology. The aircraft was the G1-80 Skyfarer, a two-seat cabin high-wing braced monoplane with a light alloy basic structure and a mixed steel tube and fabric covering. It had an unusual tail unit, a cantilever tailplane with the elevator mounted on the upper surface of the tail with aluminum endplate fins and no movable rudders. It was powered by a 75 hp (56 kW) Avco Lycoming GO-145-C2 geared air-cooled four-cylinder engine.
The aircraft incorporated aerodynamic control principles covered by patents issued to Fred Weick, an early aeronautical engineer who went on to design and market the Ercoupe. Since it had no rudders (or rudder pedals), it was simpler to fly (it had a single control wheel, which controlled the ailerons and elevator), and was considered spin-proof. The aircraft was certified in 1941 with a placard that stated the aircraft was characteristically incapable of spinning. The company also made a comment to Popular Science in a September 1941 article, with first public photos that an “average” person could learn to fly the Skyfarer …in an hour or so…
It was anticipated that many aircraft would be ordered and built, but the United States became involved in the Second World War and the Skyfarer programme was abandoned after 17 examples had been built. The rights and tooling passed to Grand Rapids Industries in 1943, who built 2 aircraft before stopping production. The company became a manufacturer of the Waco CG-4A troop glider.
L.W. DuVon and Dr. David O. Kime of Western Union College convinced the type holder Grand Rapids Industries, to give the equipment, tools and one of the finished planes to the college in 1944. They then found local investors who formed Mars Corporation in 1945. The aircraft was later licenced as the Mars M1-80 Skycoupe with a 100 hp engine. One example was built and production plans were estimated to be as high as 75 planes in its first year. The glut of aircraft produced after the war left little market for the aircraft. The facility to manufacture the aircraft was sold by 1946.
The aircraft NC29030 resides in the Plymouth County, Iowa Historical Museum.

General Aircraft GAL-42 Cygnet / Owlet
CW Aircraft was established in 1936 by C R. Chronander and J. I. Waddington to design and develop Cygnet two-seat all-metal cabin monoplane, which first flew in 1937. Rights in Cygnet acquired by General Aircraft Ltd. in 1938.
General Aircraft GAL-42 Cygnet Article
This 1936 side by side two seat training and club aircraft was an attempt at a more robust and easily made machine than those of longeron, plywood and fabric construction. It was the first British light aeroplane to have both metal skinned wings and fuselage. The first version had a single fin and rudder and a tailwheel landing gear. The later Cygnets had twin fins and a tricycle landing gear making it easier to fly.
There was also an experimental open-cockpit version, the Owlet.

General Aircraft GAL.38
In 1937 the British Admiralty issued a requirement for a novel type of aircraft to shadow enemy fleets, especially by night. The Air Ministry issued Specification S.22/37 calling for an aircraft compatible with aircraft carriers which would provide comfortable accommodation for a pilot, observer and radio operator, outstanding all round view and the ability to cruise at 40 knots for 11 hours. Two prototypes were built, the Airspeed A.S.39 (serial N1323) and the General Aircraft G.A.L.38 (P1758). These flew after the out break of the Second World War. Both were high wing aircraft with extensive slats, flaps and drooping ailerons all in the slipstream of four 130 hp Pobjoy Niagara V radials driving fixed pitch propellers. The G.A. aircraft was all wood, but the Airspeed Fleet Shadower, had a metal fuselage; the former had a nose¬ wheel and tall single fin, while the Airspeed had a tail wheel and three small fins. Each seated the observer in a panoramic nose, the pilot high and behind and the radio operator further aft. Both aircraft met the requirement but the Admiralty changed their minds about the desirability of such an air¬ craft and scrapped this programme in 1940.
