During the Winter X Games “Best Trick” competition Australian Jackson Strong was attempting a backflip on his snowmobile, when he separated from his sled and came crashing to the ground. When Strong hit the ground beside his snowmobile, the sled took off towards a fence and crashed into a group of spectators.
One man was evaluated by the medical staff after being struck by the sled, but all of the fans in attendance and Strong were able to avoid serious injury.
According to witnesses, the sled never struck a fan, but he was injured when his father pulled him out of the way of the snowmobile and he smacked into a nearby truck.

It was a scary situation and luckily no one was seriously injured. These are the types of high risk situations the fans and athletes find themselves in while attending an event like the X Games.
