Elusive schlieren picture of supersonic shockwaves emanate from NASA F-15 and F/A-18 aircraft in the air at supersonic speed were captured during new pilot skill flights. The images were collected by a twin telescope and digital camera system on the earth .Under a NASA Small Business Innovation investigate project. Schlieren photography is a method that enables imaging of airflow, with particular illumination making changes in air density—in this case the density of the shockwaves "Our team...
