A group of skydivers jump at the same time, when one is accidentally kicked in the head by his buddy. He goes unconscious, but is miraculously saved when one of his partners is able to catch him and activate his chute.
From Digg:
The terrifying footage was shared recently by Ben Pigeon, the unfortunate diver who took a fellow diver's "femur [to the] head at 200 plus mph." Pigeon writes that he lost 3 days of memory due to the concussion, but it could have been a lot worse — luckily, another diver was able to reach Pigeon and activate his chute and he was not further injured upon landing.
