An Australian man posting under the name Nomadic Adrenaline has uploaded this incredible video of the moment he suffered a seizure during a sky dive.
"Possibly the scariest moment of my life," wrote the poster.
The man, called Christopher, said his near-death experience happened during a jump last year, when he was doing stage five of his Accelerated Free Fall programme.
"At around 9000ft (2743m) I have a seizure while attempting a left hand turn. I then spend the next 30 seconds in free fall unconscious."
Noticing something was wrong, Christopher's jumpmaster soon came to the rescue. The video, which appears to be filmed from the jumpmaster's headcam, shows him approaching the unconscious man and reaching for his ripcord.
"Thankfully my jumpmaster manages to pull my ripcord at around 4000ft," wrote Christopher. "I become conscious at 3000ft and land safely back to the ground."
