He continued to be involved in the smallest of details but then would disappear for weeks. Despite the many efforts to kill the project, highly placed administration officials renewed it, though the plan was reduced to one plane.

Design presented several challenges— such a plane would require an overhang wingspan 50 percent greater than the Martin Mars, which would present new torsional, wing flutter, vibration, deflection, and control problems never before tested. Kaiser, unsuccessful in his attempt at combining forces with Hughes, had nothing more to do with the project except to help out with providing a few personnel.

Development of new tools, materials, and methods was by trial and error, consuming time, material, and money. Bis 2017 hatte dieses Flugschiff die größte Flügelspannweite sowie die größte Flügelfläche aller bisher gebauten Luftfahrzeuge. Die Spruce Goose war das erste Flugzeug mit vollständig hydraulisch angetriebenen Steuerflächen. On November 2, 1947, the taxi tests began with Hughes at the controls. Hughes was summoned to the War Investigations Committee to explain the $22m cost. Even as the project began to fall behind schedule, Hughes refused to relinquish control. In 1942 billionaire aviator, engineer, philanthropist and entrepreneur Howard Hughes won the contract to design a plane for the United States Air Force which could fly troops across the Atlantic, thus avoiding Nazi U-boats. His crew included Dave Grant as co-pilot, two flight engineers, Don Smith and Joe Petrali, 16 mechanics, and two other flight crewmen. Regarding possible resource requirements, Kaiser said he would build a steel foundry and educate and develop technicians and engineers in support of his proposal. Tatsächlich wurde aber hauptsächlich laminiertes Birkenholz in der Form von Duramold verwendet. Seven aircraft configurations were drawn up, including twin-hull and single-hull designs with four to eight engines. If it didn’t, fine.”.

In the annals of military history magazines, this is one of those moments. After Hughes’s death on April 5, 1976, the plane was put on exhibit at Long Beach, California. Anschließend wurde das Flugschiff in einem klimatisierten Hangar in Long Beach eingemottet, wobei es nach Hughes’ Anweisung in flugfähigem Zustand gehalten wurde und man sogar die Motoren jeden Monat einmal warmlaufen ließ. But his report called the plane’s design amazing and the most remarkable flying boat he had ever seen. It was to have a range of 3,000 miles at a speed of approximately 200 mph. During July and August, Kaiser made two proposals—mass production of the Martin Mars flying boat and the design and development of the 200-ton flying boat––both taken under consideration by the War Production Board, headed by Donald Nelson. Six times larger than any aircraft of its time, the Spruce Goose, also known as the Hughes Flying Boat, is made entirely of wood.

Hughes settled on a design gross weight of 400,000 pounds. .css-14iz86j-BoldText{font-weight:bold;}A billionaire tycoon was right to say his plane - the heaviest ever built - could have flown, a university team has claimed using a flight simulator. The War Production Board wanted a manufacturer who could build a giant flying boat.

But the Kaiser-Hughes partnership soon dissolved and Hughes proceeded alone.

Perhaps the key reason Hughes continued maintenance of the plane was that he saw it as his greatest aviation achievement. Among the conditions imposed were that all construction would use a minimum of any critical or strategic materials, that no engineers or technicians working for manufacturers already engaged in the war effort could be employed without the permission of their employers, that they could spend no more than $18 million, and that the program would be limited to 24 months. By August 22, 1942, after several weeks of discussion, a handshake agreement was reached—Hughes would design the plane and Kaiser would build it.
