Video surfaced Saturday of a nine-year-old boy dangling perilously from a ski lift at Liberty Mountain resort in Fairfield, Penn. He eventually falls and survives a 20-foot drop.

"At the end, they [other chairlift occupants] couldn't pull him, because it would be rocking the lift, or all three of them would fall," Adrian Delgado, the man who shot the video, told ABC News. The boy, WTTG reports, suffered a leg injury; Liberty Mountain officials are still investigating what led to his fall.
