Operational History
During a break in the Senate hearings, Hughes returned to California to run taxi tests on the H-4. On November 2, 1947, the taxi tests began with Hughes at the controls. His crew included Dave Grant as co-pilot, two flight engineers, Don Smith and Joe Petrali, 16 mechanics, and two other flight crew. In addition, the H-4 carried seven invited guests from the press corps and an additional seven industry representatives. Thirty-six were on board.
After the first two taxi runs, four reporters left to file stories, but the remaining press stayed for the final test run of the day. After picking up speed on the channel facing Cabrillo Beach, the Hercules lifted off, remaining airborne at 70 ft (21 m) off the water and a speed of 135 miles per hour (217 km/h) for around a mile (1.6 km). At this altitude, the aircraft still experienced ground effect. Having proven to his detractors that Hughes' (by now unneeded) masterpiece was flight-worthy, thus vindicating the use of government funds, the "Spruce Goose" never flew again. Its lifting capacity and ceiling were never tested. A full-time crew of 300 workers, all sworn to secrecy, maintained the plane in flying condition in a climate-controlled hangar. The crew was reduced to 50 workers in 1962, and then disbanded after Hughes' death in 1976.

Famous quotes containing the word history:
“When we of the so-called better classes are scared as men were never scared in history at material ugliness and hardship; when we put off marriage until our house can be artistic, and quake at the thought of having a child without a bank-account and doomed to manual labor, it is time for thinking men to protest against so unmanly and irreligious a state of opinion.”
—William James (1842–1910)
