This is terrifying.
A man named Christopher has posted a video of himself skydiving back in November.
The video looks like any other skydiving video; Christopher is being filmed by his jumpmaster, who dives out of the small plane with him.

Christopher floats around in the air for a few moments before it is time to pull the ripcord and begin the process of landing.
But right before Christopher is able to pull the ripcord, he suffers a massive seizure.
It's a major emergency, as Christopher cannot pull the ripcord.

Luckily, the jumpmaster is able to catch Christopher and pull his ripcord.

Here's what Christopher wrote in the video description:
Possibly the scariest moment of my life. On the 14th of November 2014 while doing stage five of my Accelerated Free Fall program I have a near death experience. At around 9000ft I have a seizure while attempting a left hand turn. I then spend the next 30 seconds in free fall unconscious. Thankfully my jumpmaster manages to pull my ripcord at around 4000ft. I become conscious at 3000 ft and land safely back to the ground.
