Grumman G-21 Goose

The Grumman G-21 Goose is an amphibious aircraft that was designed by Grumman
to serve as an eight-seat "commuter" aircraft for businessmen in the Long Island 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 United States 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,
the Goose found continued commercial use in locations from the wilderness of Alaska
to the sunny climates of Catalina and the Caribbean.
A total of 345 were built at a cost of around $62,000 per plane. With only about 30 known to still be airworthy,
today you can expect to pay around $500,000.00 for one.
