NASA's 2017 astronaut candidates toured aircraft hangar at Armstrong Flight Research Center, in Southern California. After tour of aircraft hangar and briefing on the use of aircraft for flight research, the astronauts practiced flying the X-57 simulator. Starting with the fuselage of a Tecnam P20067T, the X-57 Maxwell electric propulsion airplane is being built and could lead to the development of electric propulsion-powered aircraft, which would be quieter, more efficient and environmentally friendly than today's commuter aircraft.
