Extreme sports fans were the victims at the X Games when a snowmobile veered into a crowd after a jump went horribly wrong.

The rider himself, Jackson Strong, was lucky to escape serious injury as he lost control of his snowmobile and fell off the vehicle while attempting the risky stunt.

Onlookers in the crowd scampered to safety as the snowmobile accelerated off the slope.

Despite the terrifying footage, just one person, a teenager, was injured.
