The Boeing 307 Stratoliner was put into service #onthisday in 1940 by both Pan American and Transcontinental & Western Air (TWA). The Stratoliner was the first commercial airliner put into service to have a pressurized cabin. Named for its ability to cruise near the stratosphere, the airliner had a circular cross-section, tear-drop-shaped fuselage to handle the stresses of pressurization. Only ten were produced: one prototype, five for TWA (Transcontinental & Western Air), three for Pan American, and one for Howard Hughes. The airline touted its quietness, speed, and advanced capability of flying above bad weather and turbulence.
