Leonard Weinstein of NASA Langley developed a camera to photograph shock waves from a full-size aircraft in flight for the first time. This photo of a T-38 flying at Mach 1.1, at an altitude of 13,700 feet, was taken at Wallops in 1993. The technique, called Schlieren photography, shows density changes, and therefore shock waves, in fluid flow.
