“Goose", the largest wooden airplane ever built. This massive flying boat, also known as the Hughes Flying Boat or H-4 Hercules, was designed by Howard Hughes during World War II to transport troops and supplies across the Atlantic. Despite its name, the Spruce Goose is primarily constructed from birch wood, using a process called Duramold. The plane famously made only one flight in 1947, lasting for just 30 seconds, but this single flight solidified its place in aviation history. The museum provides information on the plane's history, including its design, construction, and its journey to its current location in Oregon. Visitors can learn about the Spruce Goose's significance as a testament to engineering ingenuity and its impact on the development of aviation.
