One of Seven H-4 Hercules Concepts

The Spruce Goose was conceived during World War II, when  there was a growing need to move troops and materials across the Atlantic Ocean. Henry Kaiser imagined the idea of a massive flying transport and turned to Howard Hughes to design and build it.  The Spruce Goose is six times larger than any aircraft of its time. Originally designated HK-1 for the first aircraft built by Hughes-Kaiser, it was re-designated the H-4 Hercules when Henry Kaiser withdrew from the project. It is made entirely of wood and flew one time on November 2, 1947, in Long Beach, California.

This drawing is one of seven different concepts of the H-4 Hercules (Spruce Goose) that were drawn. This version of the Flying Boat depicts twin booms, and one fuselage.
