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 on 2 November 1947. Built from wood due to wartime raw material restrictions to the use of aluminium, it was nicknamed the "Spruce Goose" by its critics, some of whom 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.
