The National Advisory Committee for Aeronautics, which was founded in 1915, is the root of the US space program currently known as NASA. NASA (National Aeronautics and Space Administration) has been a world leader in aviation-related research and development. Currently, NASA's top priority is joint research with industry leading to the development of an economical and environmentally safe supersonic passenger jet known as the High Speed Civil Transport. This passenger jet would be able to fly from Los Angeles to Japan in about four hours. This plane represents a potential market of five hundred to a thousand planes worth an estimated $200 billion and approximately 140,000 jobs.
