The H-4 Hercules, better known as the "Spruce Goose" was built out of necessity in the shadow of World War II, as Allied ships were being decimated by German U-Boats. In 1942, the U.S. Government began the search for a heavy lift transport plane that could ferry men and equipment across the Atlantic. Henry J. Kaiser and Howard Hughes combined forces to create what would be the largest plane ever constructed, a title the H-4 would hold until 2017. Because of the war effort, exotic materials like aluminum couldn't be used in the construction, so Hughes used birch to create a flying boat that could carry 150,000 lbs.
Giles and I have been fascinated by the story of the H-4 Hercules since childhood. The sheer ambition of building an aircraft on that scale using wood is remarkable. The Hercules is a true engineering triumph that pushed the boundaries of aeronautical design. It paved the way for the large aircraft we use today, and did it with style, panache and just a dash of Hollywood.

The Hercules was a monumental undertaking. It is the largest aircraft ever built. It is over five stories tall with a wingspan longer than a football field. That's more than a city block. Now, I put the sweat of my life into this thing. I have my reputation all rolled up in it and I have stated several times that if it's a failure, I'll probably leave this country and never come back. And I mean it.
