BusinessInsiderreported that work continueson a prototype of the jet, butportionsof the aircraft have beenreleased to the public, includingtesting of Lynx'ssupersonicenginelast week.
The vehicle was dropped from a carrier aircraft high above California's Mojave Desert and ignited its rocket engine to go supersonic for a few seconds.
Most recently, a team from Stanford took the helm of Sequoia to run computational fluid dynamics simulations -- a process that requires a finely tuned balance of computation, memory and communication components -- in order to better understand engine noise from supersonic jets.
In 1956, the Supersonic Transport Aircraft Committee met in England to discuss building a supersonic airliner by British aircraft and engine manufacturers and the government.
