Boeing 307 Stratoliner "Clipper Flying Cloud" at the Udvar-Hazy Center

First flown in late 1938, the Boeing 307 was the first airliner with a pressurized fuselage. It could carry 33 passengers in great comfort and cruise at 6,096 meters (20,000 feet), while maintaining a cabin pressure of 2,438 meters (8,000 feet). This enabled the Stratoliner to fly above most bad weather, thereby providing a faster and smoother ride.
