A man who purportedly survived a seizure while skydiving from 12,000 feet in Australia said he spent 30 seconds — unconscious — in free fall before his instructor saved him in what he described as the "scariest moment" of his life in a video published on YouTube on Sunday. The man, who was only identified as Christopher, he was in stage five of his accelerated free fall program on Nov. 14 when he started to have a seizure while attempting a left-hand turn at around 9,000 feet. NBC News could not independently confirm the authenticity of the video and attempts to reach "Christopher" have been unsuccessful.
