After U.S.-German relations had deteriorated from neutral to hostile around 1916, the prospect of
U.S. war entry became possible. On February 15, 1917, the newly established
Aviation Week warned that the
U.S. military aviation capability was less than what was operating in the
European war. President
Woodrow Wilson sent
Jerome Hunsaker to Europe to investigate, and Hunsaker's report prompted Wilson to command the creation of the nation's first aeronautics laboratory, which became NASA Langley. In 1917, less than three years after it was created, the
NACA established the
Langley Memorial Aeronautical Laboratory on
Langley Field. Both
Langley Field and the Langley Laboratory are named after aviation pioneer
Samuel Pierpont Langley. The
Aviation Section, U.S. Signal Corps had established a base there earlier that same year. The first research facilities were in place and aeronautical research was started by 1920. Initially, the laboratory included four researchers and 11 technicians. Langley Field and NACA began parallel growth as air power proved its utility during
World War I. The center was originally established to explore the field of aerodynamic research involving airframe and propulsion engine design and performance. In 1934 the world's largest wind tunnel was constructed at Langley Field with a test section; it was large enough to test full-scale aircraft. It remained the world's largest wind tunnel until the 1940s, when a tunnel was built at NASA's
Ames Research Center in California. The
West Area Computers were
African American, female
mathematicians who worked as
human computers at the Langley Research Center from 1943 through 1958. The West Computers were originally subject to Virginia's
Jim Crow laws and got their name because they worked at Langley's West Area, while the white mathematicians worked in the East section. Early in 1945, the center expanded to include rocket research, leading to the establishment of
a flight station at
Wallops Island, Virginia. A further expansion of the research program permitted Langley Research Center to orbit payloads, starting with NASA's
Explorer 9 balloon satellite in mid-February 1961. As rocket research grew, aeronautics research continued to expand and played an important part when subsonic flight was advanced and supersonic and hypersonic flight were introduced. Langley Research Center claims many historic firsts, some of which have proven to be revolutionary scientific breakthroughs. These accomplishments include: Development of the concept of research aircraft leading to supersonic flight, the world's first transonic wind tunnel, training the first crews of astronauts, the
Lunar Landing Facility which provides the simulation of lunar gravity, and the Viking program for Mars exploration. The center also developed standards for the grooving of aircraft runways based on a previous British design used at
Ronald Reagan Washington National Airport.
Grooved runways reduce
aquaplaning which permits better grip by aircraft tires in heavy rain. This grooving is now the international standard for all runways around the world. Langley was also a contender for the site of
NASA Mission Control, prior to the eventual selection of Houston, due to Langley's prominence with NASA at the time, the large existing aerospace industry already present in the Hampton Roads region, and the proximity to Washington, D.C. The selection of Houston actually took many higher-ups at Langley by surprise and caused some lingering controversy in the surrounding area over the loss and transfer of so many jobs to Houston. Though they had lost out on the Manned Spacecraft Center, Langley still played an important role in conducting research and training during the Apollo Program. ==Departments==
