A Boeing Model 307 Stratoliner, in Pan Am service, in low-level flight. Using the wings, tail, and engines of the Boeing B-17C bomber, it first flew on December 31, 1938, with Boeing test pilot Eddie Allen, and was the first pressurized airliner. It could fly at 20,000 feet, with 33 passengers, and ten of them were produced, with three of them going to Pan Am, five to Transcontinental & Western, one to Howard Hughes, as the Model 307B. The prototype, with registration number NX19901, was destroyed in a crash, on March 18, 1939, near Mount Rainer, during a test flight for KLM Airways. In 1942, during World War II, the aircraft were impressed into American military service, under the designation C-75. Only one Boeing Stratoliner still exists, which was originally the Pan Am Clipper Flying Cloud, with registration number NC19903, and it is now on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center, at Washington Dulles International Airport. This aircraft, however, was almost destroyed in a crash, into Elliott Bay, when it developed engine trouble during a test flight in Seattle, Washington, on March 28, 2002, after its restoration, by Boeing. |
