The Goodyear GA-2 Duck was a 1940s American three-seat light amphibian built by the Goodyear Aircraft Corporation.
The design team included David Thruston, who later developed several other light seaplanes including: the Colonial Skimmer, Lake Buccaneer, Thruston Teal and Seafire.
Only 19 aircraft were built and these were used as only for testing and as demonstrators.

Re: Goodyear GA-2 Duck
Design and development
The Goodyear Aircraft Corporation began to design a small and light amphibian before the end of the Second World War.
The prototype designated GA-1 first flew in September 1944.
It was a cantilever high-wing monoplane with underwing stabilizing floats.
The GA-1 had an all-metal fabric-covered wing, an all-metal single-step hull, and a cruciform tail unit.
It had a retractable tail-wheel, accommodation for two, and a pylon-mounted piston engine with a pusher propeller.

Operational history
After successful testing of the prototype, 18 demonstration aircraft were built.
These differed from the prototype in that they had room for the pilot and two-passengers.
Two versions were built, the GA-2 with a 145 hp (108 kW) Franklin 6A4-145-A3 piston engine, and the GA-2B with a more powerful 165 hp (123 kW) Franklin 6A4-165-B3 flat-six piston engine.
Although the aircraft were successfully tested and demonstrated, the costs involved in producing the aircraft prevented it being sold at a price that private pilots could afford, and the project was abandoned.
In 1950 a revised four-seat variant the GA-22 Drake was flown followed in 1953 by the GA-22A Drake, only one of each was built.
