A man who survived a seizure while skydiving was amazingly rescued by his instructor in Pinjarra, Australia.

In an incredible scene that was caught on tape, Christopher Jones, 22, is seen jumping out of a plane seconds before he suffered the seizure and started free-falling backwards.

The instructor who was on the dive, Sheldon McFarlane, was able to reach Jones and pull the rip cord for him. Jones eventually regained consciousness and landed safely.

Jones has a history of seizures, but had not suffered one in four years. 

The jump reportedly occurred in November, but McFarlane just posted the helmet cam footage on YouTube, where it's been viewed 4 million times in the last day.

Dr. Marc Siegel explained this morning that a seizure is a burst of electrical activity in the brain. He said there is less oxygen pressure at higher altitudes, which can cause a seizure. 

Siegel said when Jones woke up again, he was at a lower level with more oxygen pressure. Siegel cautioned that people with a history of seizures cannot fly planes and should not be skydiving.

Then on "Fox and Friends," we saw the first U.S. interview with McFarlane, who took us through the harrowing turn of events.

He said Jones had done several other successful skydives with him and had been a "textbook student."

Since each skydiver is equipped with a parachute that automatically activates at a certain point, Jones was never in danger of making it all the way down with no parachute. 

"The equipment we use is actually fitted with two automatic activation devices, one to open his main parachute at 2,500-3,000 feet and one to open the emergency parachute at about 750 feet above the ground. So I don't think Chris was in any danger of hitting the ground without a parachute above his head," said McFarlane.
