The Hughes H-4 Hercules (registration NX37602) is a one-off heavy transport aircraft designed and built by the
Hughes Aircraft company, making its first and only flight in 1947. Built from wood due to wartime
raw material restrictions, it was nicknamed the "Spruce Goose" by its critics, who accused
Howard Hughes of misusing government funding to build the aircraft. The Hercules is the largest
flying boat ever built, and has the largest wingspan and height of any aircraft in history. It survives, in good condition, at the
Evergreen Aviation Museum.
