"He's obviously got himself out of his restraint somehow," Mark Charnley told Sky News. "Two seconds after that he actually fell out of the carriage to the floor, maybe around [12 to 15 feet] he fell.

“[The boy] mustn’t have been strapped in right, or too small for ride. As it went down the fast bit towards the ‘souvenir’ camera he slid out and over the top of the carriage,” parkgoer Simon Moran recounted, as per The Daily Telegraph.

Charnely, who was on the ground waiting in line at the time of the accident, said that witnesses started shouting at the ride attendant when they saw what was happening “as he hadn’t noticed what had gone on.”

“Two guys dove over the actual barriers to get to the lad who was on the floor,” Charnley added.
