In Iraq on September 3, 2004, United States Marine Corps military photographer Lance Corporal Andrew Z. Williams used his digital camera to capture still photos of flares fired by two U.S. Marine Corps KC-130 Hercules Tanker/Transport aircraft. The stunning and crisp images, shot from above the KC-130s, include the the aircrafts’ wingtip vortices, popularly known as "angel decoys," which are visible due to the flare salvos.
