A family’s dream vacation turned into a nightmare after their 10 year old son lost his balance and tumbled 100 feet into the Niagara Gorge. This horrible event happened at about 4:34pm on October 16, according to buffalonews.com.

The boy  was sitting on the railing at Niagara Gorge, posing for a picture for his mom, when this tragedy happened.

“As he adjusted his seating position on the railing, he lost his balance and fell backwards,” Shawn Black, Sergeant of the Niagara Parks Police Service, reported in a press release.

The boy was adjusting his position when he lost his balance. He fell 25 meters injuring his head, BBC reported. Niagara Parks Police High Angle River Team and Niagara Emergency Medical Service were able to stabilize the boy so he could be taken by helicopter to McMaster Children’s hospital in nearby Hamilton, Ontario, according to foxnews.com.

BBC News reported that about a dozen people have gone over the edge and into the falls in 2011, using a barrel or some other device. A similar incident occurred in June. Kirk Jones died after he plunged off the falls in an inflatable ball. Jones survived a similar stunt in 2003 when he became the first to survive the plunge without any safety device. It was believed he took a boa constrictor with him during his June plunge. At least two people have survived unprotected plunges since Jones’s incident.

The boy’s injuries originally were considered life-threatening, but the hospital later changed his conditions to serious but stable.
