Skydiver Suffers Seizure Mid-Jump (VIDEO)

This could have ended very badly if not for a brave skydiving instructor who stepped in and performed a thrilling rescue.

22-year-old Christopher Jones was taking skydiving lessons at the Western Australia Skydiving  Academy when he suffered an almost-fatal seizure, calling it "possibly the scariest moment of my life."

Jones jumped from the plane at 12,000 feet, followed by instructor Robin O'Neill. "At around 9,000 feet I have a seizure while attempting a left hand turn," Jones writes in the YouTube description. "I then spend the next 30 seconds in free fall unconscious." O'Neill saw that Jones was having trouble and was able to pull Jones' ripcord at around 4000 feet. Jones says that he regained consciousness at about 3000 feet and was able to land safely.
