NASA and Boeing's blended wing X-48C has flown its 100th flight, marking a major milestone for the experimental aircraft. The unmanned aerial vehicle has been modified to investigate noise-shielding concepts with a blended wing body design, combined with mounting the engines on top of the fuselage and shielding them with both the horizontal and vertical tail surfaces. Twenty more test flights are on tap before the blended wing body program is completed. (Image Credit: NASA)
