T-38C Passes in Front of the Sun at Supersonic Speed

An Air Force Test Pilot School T-38C passes in front of the sun at a supersonic speed, creating shockwaves that are caught photographically for research. NASA is using a modern version of schlieren imagery to visualize supersonic flow phenomena with full-scale aircraft in flight. The results will help engineers design a quiet supersonic transport.
