Becky: We're eating on the Spruce Moose
First designated HK-1 (Hughes/Kaiser), later changed to H-4 when Henry Kaiser withdrew from the project, The Hughes Flying Boat is commonly called the "Spruce Goose". The aircraft is a cargo-type flying boat designed to transport men and materials over long distances. Originally conceived by Henry Kaiser (famous for the production of liberty ships) the aircraft was designed and constructed by Howard Hughes and his staff. The Hughes Flying Boat is of a single hull, eight-engine design, with a single vertical tail, fixed wing-tip floats, and full cantilever wing and tail surfaces. The entire airframe and surface structures are composed of laminated wood (primarily birch). All primary control surfaces except the flaps are fabric covered. The "Spruce Goose" hull is divided into two areas: a flight deck for the operating crew and a large cargo deck. Access between the two decks is provided bv a circular stairway. Below the cargo deck are fuel bays divided by watertight bulkheads.
