Grumman G-21 Goose

The Grumman G -21 Goose ( German goose) is a twin-engine amphibious aircraft in all-metal construction of the U.S. manufacturer Grumman Aircraft.

Development and Construction

The G21 is designed as a high-wing monoplane and has a retractable landing gear. It was planned in 1937 as a six - or seven -seat business aircraft business ( such as the department store owner Marshall Field, E. Roland Harriman financier and banker Henry Morgan ) in coastal regions such as Long Iceland. To this end, the flying boats were equipped with cabins for only two to three people and a bar on board and a toilet. Soon she was but already used by the U.S. Navy and the U.S. Coast Guard as a reconnaissance transport and rescue aircraft.

During the Second World War, the machine was also used by the Canadian Air Force and the Royal Air Force as rescue and transport aircraft.

After the war, many of the 345 units built were re- used in civil aviation. About 60 copies are still airworthy today. Since the type-certificate still exists, the former tax adviser V. L. Franklin plans after buying the rights, including design drawings, a new production of a modernized version in Graham ( North Carolina). These will be powered by Pratt & Whitney PT6A - engines with 500 kW, which were already retrofitted with some Goose and allow a cruising speed of over 370 km / h and a range of more than 2200 km. The first "Super Goose " should start in the second quarter of 2009 for its maiden flight. As a selling price about three million U.S. dollars were sought.

This type of aircraft has a central role in the series The sky dogs of Boragora, is the main character of the pilot and owner of a G -21.
