In McMinnville, Ore., the financial troubles of a private aviation services company are causing big headaches for the museum that is home to Howard Hughes' H-4 Hercules, the flying boat better known as the Spruce Goose.
On Dec. 31, Evergreen International Airlines, a subsidiary of troubled Evergreen International Aviation, filed a petition for Chapter 7 bankruptcy. The possible demise of the cargo carrier has tourists, aviation buffs and many in the museum world concerned about the fate of the affiliated Evergreen Air & Space Museum.
In Oregon's wine country, about 40 miles southwest of Portland, the museum welcomes about 150,000 visitors a year. The collection includes everything from a Lockheed SR-71 Blackbird to a Boeing B-17 Flying Fortress.
But the centerpiece of the collection is undoubtedly the original Spruce Goose.
Built primarily of lightweight birch because of World War II restrictions on metals, the airplane has the world's largest wingspan (320 feet) and made its only flight—of less than a mile—on Nov. 2, 1947, with Hughes himself at the controls. It then was put in storage.
During the 1980s, the craft was displayed under a dome in Long Beach, Calif., next to the Queen Mary cruise ship. Disney briefly managed that money-losing complex. In the early 1990s, however, the Spruce Goose was shipped to Oregon in pieces and reassembled inside a new building at the Evergreen Aviation & Space Museum.

Although an Oregon Department of Justice investigation is underway into possible inappropriate commingling of company and museum funds, officials at the museum have issued statements reassuring the public that the artifacts, especially the Spruce Goose, are safe; that the museum is an independent, financially stable nonprofit; and that, with its adjacent aviation-themed water park, it remains open for business.
