These images from NASA show for the first time the interaction of shockwaves from supersonic planes ✈️✈️ in flight. NASA captured the groundbreaking images as part of an effort to develop a jet that flies faster than the speed of sound and produces shockwaves that create “only a quiet rumble” rather than a thunderous boom. “We’re seeing a level of physical detail here that I don’t think anybody has ever seen before,” said one researcher. “This is a very big step.” (?: NASA)
