In a video posted on YouTube. a skydiver shows his near-death experience.
He was jumping from nearly 12,000 feet when he is shown on camera, from the jumping partner’s point of view.
Around 9000 feet the camera shows him having a seizure and he says he loses consciousness for about 30 seconds.
Luckily around 4000 feet his partner pulled his parachute ripcord and he regains consciousness around 3000 feet.
He then landed safely.
