The cameras strapped to the skydivers' helmets were supposed to memorialize their perfectly timed jumps and exhilarating descent from two small planes to the earth 12,000 feet below.
Instead, the footage filmed by five daredevils shows the terrifying moment when the aircraft collided above Wisconsin, flinging parachuters into the air like plastic action figures and sending one plane into a fiery dive across a sunset-lit sky.
The images in the video, exclusively licensed by NBC, are heart-stopping: One Cessna suddenly sandwiched atop another; the legs of a jumper dangling over the tail of a plane; a skydiver hanging onto a step like an acrobat before he lets go; a fireball roaring out of one plane as it plunges downward.
The thrill-seekers' helmets also filmed the miraculous aftermath of the crash: one by one, the jumpers landing on the ground, shaken but largely uninjured, and hopping into a truck to gather up the others.
