Using a Beechcraft B200 and two T-38 trainers, NASA was able to take Schlieren photos of multiple supersonic aircraft from another aircraft for the first time.

Schlieren photography is a technique used to image the flow of fluids of differing densities, and is useful for understanding shockwaves and sonic booms from supersonic planes. In this case, NASA was able to image the interaction of the shockwaves from two aircraft exceeding Mach 1, which may lead to quieter Mach busters in the future.
