In late 2010, NASA awarded contracts to three teams - Lockheed Martin, Northrop Grumman, The Boeing Company - to study advanced concept designs for aircraft that could take to the skies in the year 2025.

Less noise, cleaner exhaust and lower fuel consumption - future aircrafts will do that all at the same time. The aircraft will be operated in safely and more modernized air traffic system. Take a look at some images of concepts...
