The Spruce Goose, Howard Hughes, and the One-Mile Hop Off Long Beach Harbor That Silenced Every Man Who Said She'd Never Fly

On November 2, 1947, Howard Hughes lifted the Spruce Goose - a 200-ton wooden flying boat with a 320-foot wingspan - about 70 feet off the water of Long Beach Harbor and flew it roughly one mile at around 80 miles per hour. The flight lasted barely a minute, and the aircraft never flew again. But it was enough to silence a U.S. Senate committee that had publicly branded Hughes a fraud whose airplane would never leave the water.

What Was the Spruce Goose?

The Spruce Goose was a giant wooden flying boat officially named the H-4 Hercules. Its scale is hard to overstate. The wingspan measured 320 feet - wider than a Boeing 747, whose wingspan is about 211 feet. Its tail stood as tall as an eight-story building, and it was powered by eight engines.

The aircraft held the record for the widest wingspan of any airplane ever built for roughly seven decades.

Nearly every part of it was made of wood, primarily birch - not spruce. The nickname “Spruce Goose” was a piece of press shorthand that Howard Hughes reportedly hated.

Why Was It Built Out of Wood?

The project began during World War II, when German U-boats were sinking Allied ships in the Atlantic faster than they could be replaced. Every lost ship took men, tanks, fuel, and food to the bottom.

Steel magnate Henry Kaiser proposed a solution: instead of shipping cargo across the water, fly it over the submarines entirely. He envisioned a flying boat large enough to carry a Sherman tank or a couple hundred troops. Kaiser turned to Hughes to build it.

The aircraft was made of wood on purpose. Aluminum and steel were reserved for fighters, bombers, and ships, so Hughes and his chief engineer, Glenn Odekirk, developed a technique called Duramold - thin sheets of laminated birch glued and shaped under heat and pressure into components that were remarkably strong for their weight. The result was furniture-grade craftsmanship on the scale of an ocean liner.

Why Did the Spruce Goose Become a Scandal?

The war ended before the aircraft was finished. By the time Hughes had it near completion in 1947, the U-boat threat was gone and so was the need for the plane. Yet the government had sunk roughly $22 million of taxpayer money into a wooden airplane that had never left the water - a fortune in 1947 dollars.

A Senate committee called a hearing. Senator Owen Brewster hauled Hughes before the cameras and effectively accused him of fraud, calling the aircraft a boondoggle - a “flying lumberyard” that would never fly. There was political bad blood underneath it, tangled up with a fight over the airline industry.

Hughes told the committee he had put the sweat of his life into the airplane. He said that if it failed, he would probably leave the country and never come back. Then he stated flatly that, whatever they chose to believe, the airplane was going to fly. He flew home to California to prove it.

What Happened During the One-Mile Flight?

Officially, November 2, 1947 was scheduled as a taxi test. Hughes told everyone the crew would simply run the flying boat up and down Long Beach Harbor to check its handling. Reporters were aboard, along with a flight engineer, a hydraulics man, technicians, and a newsreel radio broadcaster narrating live.

Hughes took the left seat of a cockpit the size of a living room, working eight throttle levers for eight Pratt & Whitney radial engines - 28 cylinders and 3,000 horsepower apiece.

The runs escalated:

First run: down the harbor and back, uneventful.
Second run: faster; the boat rose onto the step - the point where a flying boat skims the surface instead of plowing through it - then settled back down.
Third run: Hughes pushed all eight throttles forward without telling the reporters what he intended. The pounding of the hull against the water suddenly went silent. The aircraft lifted off.

Hughes held the Spruce Goose about 70 feet above the water for roughly one mile at around 80 mph, riding the cushion of ground effect trapped between the enormous wing and the surface, then set it down softly. The entire flight lasted perhaps a minute.

It was enough. Every official who had insisted the airplane would never leave the water was now watching newsreel footage of it doing exactly that - with its builder at the controls, betting his own life on his own wood and glue.

Why Did the Spruce Goose Never Fly Again?

The flight was never really about the wartime mission anymore. The war was over, and no fleet of these aircraft was going to be built. This flight was about one man’s word. Hughes had been called a liar in front of the entire country, and he answered the only way a pilot could - by getting in the airplane and flying it.

Afterward, Hughes kept the Spruce Goose in a climate-controlled hangar in Long Beach for the rest of his life. Until his death in 1976, he paid a full crew of engineers to keep the aircraft flight-ready for a flight that would never come - spending a fortune quietly for nearly thirty years.

Some called it madness. Hughes did struggle with worsening personal demons over those years. But to many pilots it reads differently: a man who could not bear to let a beautiful machine become junk.

Where Is the Spruce Goose Today?

After Hughes died, there was a fight over the aircraft’s fate, and some wanted to break it up. It survived. Today the Spruce Goose - the H-4 Hercules - resides at the Evergreen Aviation and Space Museum in McMinnville, Oregon, in the Willamette Valley, where a building was constructed around it.

Visitors can walk directly beneath the 320-foot wing and look up into the cockpit where Hughes made good on his word. Roughly 80 years later, the birch remains solid.

Key Takeaways

On November 2, 1947, Howard Hughes flew the Spruce Goose about one mile at roughly 70 feet and 80 mph off Long Beach Harbor - its only flight ever.
The H-4 Hercules had a 320-foot wingspan, wider than a Boeing 747, and was built from laminated birch using the Duramold process because wartime metal was reserved for combat aircraft.
The government spent about $22 million on the aircraft, and Senator Owen Brewster publicly accused Hughes of fraud before the flight proved the critics wrong.
Hughes kept the plane flight-ready in a climate-controlled hangar until his death in 1976.
The Spruce Goose is now on display at the Evergreen Aviation and Space Museum in McMinnville, Oregon.
