In August 1999, the Transportation Research Board (TRB) held a workshop at the request of the National Aeronautics and Space Administration (NASA) to examine its Small Aircraft Transportation System (SATS) concept. Individuals from the aviation, transportation infrastructure, public policy, research, and finance communities were invited to participate in the 2-day event, during which managers from NASA’s Office of Aerospace Technology described their ongoing efforts to advance the state of technology in general aviation and to further the development and use of advanced small aircraft as a means of personal transportation
