We have mentioned the increased efficiency and lower emissions of blended wing body aircrafts before—like the X-48B, now in its prototype testing phase. Seeing two of them getting ready to take off, however, pushes the concept from the That's Pretty Cool to the Geezussrollerbladingchrist, We Want These So Badly category. Even if it's just a synthetic image, they look absolutely stunning. [Note: I heard somewhere that the reason why commercial wings didn't fly is that people don't want to fly on things without passenger windows; Trust issues and the like. - B.L.][Flight Global]
