The Boeing 307 Stratoliner or “Clipper Flying Cloud” was the first airliner with a pressurized fuselage. First flown in 1938, it could carry 33 passengers in great comfort and cruise at 20,000 feet, while maintaining a cabin pressure of 8,000 feet.  This was a great leap in commercial air travel enabling the Stratoliner to fly above most bad weather, providing a faster and smoother ride.

This beautiful plane is found at the Boeing Aviation Hanger at the Udvar-Hazy Center, part of the National Air and Space Museum.
