Floatplanes & Amphibians | Grumman G-21 Goose The Grumman G-21 Goose is an amphibious aircraft designed as an eight-seat commuter plane. The Goose was Grumman’s first monoplane, first twin-engine aircraft, and first aircraft for commercial service. During WWII the Goose was used as a military transport. The G-21 Goose is an all-metal, high-winged monoplane powered by two 450 HP nine-cylinder Pratt & Whitney R-985 Wasp radial engines. The deep fuselage hull has a hand-cranked retractable landing gear and ample interior space to be a small airliner.
