Brute Strength!

At the center of our museum stands the one and only H4 Hercules (a.k.a. Spruce Goose). Many people are aware that the Spruce Goose was flown only once in 1947 at an altitude of only 70 feet for one minute. But, did you know that this winged behemoth measures 218 ft long, 79 ft high, with a wingspan of 320 ft and weighs 250,000 lbs (125 tons) and it boasts 8 Pratt & Whitney R-4360 Wasp Major 28-cylinder, 3,000 hp air-cooled radial piston engines?

That makes the H4 Hercules the biggest, most powerful, and heaviest radial engine powered amphibious aircraft in the world.

Learn more about the history, first flight, and legacy of this mammoth plane.

Better yet, come see it for yourself at the Evergreen Aviation & Space Museum, in McMinnville, Oregon.

Amazing machine!

Is it still in the Evergreen Museum?

It’s one of the machines I definitely want to see in person.

All the best,
