The Grumman G-21 Goose amphibious aircraft was designed as an eight-seat “commuter” plane for businessmen in the Long Island https://isbndirect.com/ area. The Goose was Grumman’s first monoplane to fly, its first twin-engined aircraft, and its first aircraft to enter commercial airline service. During World War II, the Goose became an effective transport for the US military (including the Coast Guard), as well as serving with many other air forces. During hostilities, the Goose took on an increasing number of combat and training roles. The adaptable transport continued in postwar use.
In 1936, a group of wealthy residents of Long Island, including E. Roland Harriman, approached Grumman and commissioned an aircraft that they could use to fly to New York City. In response the Grumman Model G-21 was designed as a light amphibian transport. The typical Grumman rugged construction was matched to an all-metal, high-winged monoplane powered by two 450 horsepower (340 kW) Pratt & Whitney R-985 Wasp Jr. nine-cylinder, air-cooled radial engines mounted on the leading edge of high-set wings. The deep fuselage served also as a hull and was equipped with hand-cranked retractable landing gear. First flight of the prototype took place on May 29, 1937.
The fuselage also proved versatile as it provided generous interior space that allowed fitting for either a transport or luxury airliner role. Having an amphibious configuration also allowed the G-21 to go just about anywhere, and plans were made to market it as an amphibian airliner. Some had a hatch in the nose, which could remain open in flight.
The Supermarine Sea Eagle was a British, passenger–carrying, amphibious flying boat. It was designed and built by the Supermarine Aviation Works for its subsidiary, the British Marine Air Navigation Co Ltd, to be used on their cross-channel route between Southampton, the Channel Islands and France.
Three aircraft were constructed, G-EBFK, G-EBGR and G-EBGS and the regular service between Southampton and Guernsey began on 25 September 1923 (the planned service to France was never implemented). This was the world’s first scheduled passenger air service by flying boat. However, G-EBFK crashed on 21 May 1924; in January 1927, G-EBGS was lost when it was rammed by a ship in the harbor of St Peter Port, Guernsey. The third aircraft continued on the route until 1928 when it was replaced by a Short S.8 Calcutta.
The wooden hull of the surviving Sea Eagle, G-EBGR, was retained by Vickers until 1949, when they presented it to the British Overseas Airways Corporation; BOAC burnt it in 1954 because of a lack of storage space.
The Vickers Viking was a British single-engine amphibious aircraft designed for military use shortly after the World War I. Later versions of the aircraft were known as the Vickers Vulture and Vickers Vanellus.
