NASA Langley Turns 90
The NASA Langley Research Center, America's first civilian aeronautics laboratory, celebrated its 90th birthday on October 27, 2007. Opened in 1917 as the Langley Memorial Laboratory, the Center was the site of most of the pioneering aviation research conducted by the National Advisory Committee for Aeronautics. The flight testing facility featured the first pressurized (variable density) wind tunnel which was used to gather precise data on wing shapes. After the formation of NASA in 1958, the Laboratory continued its groundbreaking research by leading the development of winglets, supercritical wings, and numerous other innovations now widely incorporated into modern airliner design.
