GoPro camera captures free-fall from 12.5K feet when skydiver drops it (video, not safe for epileptics)

[Video Link] Warning: do not watch if you're epileptic. "MartialArt23," the YouTube user who shot and uploaded this video, explains:

[I] bumped my head on the door frame on exit unclasping the latch on the box. The camera popped out on exit at 12.500 and fell straight down onto the landing area at the DZ and was recovered by a fellow skydiver. It even caught our landings. Not one scratch on the body or lens. Still can't believe that I got it back and that it is totally fine. A buddy the same day who is one of our camera flyers had the same thing happen but with his SLR….not the same result. I'm definitely a gopro fan for life these little guys are bomb proof.
