NASA's aircraft of the future (images)

From a 2010 event came this design from NASA and GE Aviation for a business-type, 20-passenger jet that would be lighter and more aerodynamic than the airplanes of today. Plus, it was designed to be quieter and more fuel efficient. 

The plane flies on "ultra-quiet turboprop engines, virtual reality windows and is designed to fly at Mach 0.55 for 800 nautical miles," according to NASA.
