It looks cool, and if it works, it'd be a boon to the environment as well. Needless to say, a lot of hopes are riding on Boeing's new blended-wing aircraft: the X-48B.

With the blended wing aircraft system , the fuselage and wings are combined onto one frame, taking away the need for a tail, as well as reducing drag and fuel consumption. This fuel-saving design could reduce fuel consumption by 30% and even allow for different types of military and commercial uses.

While conventional uses for the aircraft are far from feasible at the moment, it could be used as a fuel tanker and commercial airplane in as little as 20 years' time. Hopefully, this current test flight will pass with flying colors and get us all one step closer to a more fuel-efficient airspace.
