About the G-21 Goose

The Grumman G-21 Goose is an American twin-engine fixed-wing aircraft built for utility transport operations. Designed to accommodate passengers, it functions as an amphibious flying boat capable of operating from both land and water.

Developed as a versatile transport for wealthy private clients who wanted a private amphibian, it took its maiden flight in the late nineteen thirties. Production ultimately reached a total of three hundred forty-five examples, which found widespread utility across various military and civilian operators.
