I toured a Concorde, the discontinued supersonic commercial jet flown by celebrities and royals. Take a look inside.

A Concorde plane at the Intrepid Museum. NekomuraKatsuo/Getty Images Concorde, the first and only supersonic commercial jetliner, operated from 1976 to 2003. Flown by royals, celebrities, and executives, it was discontinued because of high operating costs. A Concorde plane is open for public tours at the Intrepid Museum in New York City. Supersonic passenger air travel is a thing of the past, but you can still tour the plane that made it possible. In 1962, the governments of Britain and France signed the Anglo-French Agreement, pooling their money and resources to develop a supersonic commercial jet . The name "Concorde" was chosen because it means unity or harmony in both English and French. The first test flight was conducted in 1969, and Concorde flew commercially for the first time in 1976.
