wrong place!
In the footage, which has had more than 2.5 million views since it was uploaded to YouTube yesterday, the man is seen jumping from a plane before suffering a seizure seconds into the dive.
The nail-biting incident then unfolds with the man's instructor trying to grab a hold of him in freefall to deploy the parachute.
Perth man Christopher Jones, 22, was halfway through his skydiving training program when he made the jump in November.
WA Skydiving Academy business manager and chief instructor Robin O'Neill said Christopher was the perfect student before his last terrifying dive.
"Halfway through the skydive, he had a seizure and rolled onto his back," Mr O'Neill said.
He said the instructor on the dive, Sheldon McFarlane, managed to get hold of Christopher and pulled his rip cord.
"The guy came to consciousness under the canopy well before he landed," Mr O'Neill said.
"He landed uneventfully. It was a controlled landing in the Pinjarra drop zone."
Mr O'Neill said no ambulance was called, and Christopher's mother collected him and took him home.
He said the academy had a questionnaire specifically asking course participants whether they had illnesses and conditions such as epilepsy.
"(Christopher's) treating specialist wrote a letter specifically saying he was fit for skydiving," Mr O'Neill said.
"Obviously he wasn't.
"That was the end of his skydiving career."
