SOLE SURVIVING BOEING 307 STRATOLINER ARRIVES AT DULLES AIRPORT AFTER ITS FINAL FLIGHT, 2003-08-06 (photo)

View of the port wing and fuselage of the world's sole remaining Boeing  307 Stratoliner after it arrived at Washington's Dulles International  Airport following its final flight ever, August 6, 2003. The aircraft,  the world's first pressurized airliner, capable of flying at altitudes  of around 20,000 feet, will join the Smithsonian's National Air and  Space Museum's collection at the Udvar-Hazy Center, where artifacts  that cannot fit in the main museum in downtown Washington will be  housed. This particular aircraft, built in the late 1930s, was  originally delivered to Pan American Airways, where it was christened  "Clipper Flying Cloud." It then had a colorful career, flying for the  U.S. Army Air Forces in WWII, returning to airline service in 1946,  then passing through the hands of several owners, including infamous  Haitian leader "Papa Doc" Duvalier.
