Like the arena announcer said, with animals, especially these big strong ones like the Clydesdales, it takes an incredible amount of training to keep a situation like this from getting completely out of control. When two horses turned around and twisted back into the horse train, this accident looked like it could go very wrong. Watch how fast the team of professionals were able to calm the situation down and keep the horses under control. One viewer Melissa posted "the horse next to the one that was down, while still hitched to the wagon was an absolute saint of a horse, how calm he stayed as the other one was trying to get up and falling into him helped the whole situation."
