This computer-generated image shows a possible future "flying wing" aircraft, very efficiently and quietly in flight over populated areas. This kind of design, produced by Northrop Grumman, would most likely carry cargo at first and then also carry passengers.
This design is among those presented to NASA at the end of 2011 by companies that conducted NASA-funded studies into aircraft that could enter service in 2025.
