At this link: http://www.history.com/shows/full-metal-joustingHISTORY is bringing back the most dangerous collision sport in history and transforming it into a 21st-century event. But this is no Renaissance fair as the toughest riders in the nation face off in a bone-crushing competition for big money. It's as intense as it was 500 years ago, but with a twist: Traditional armor is replaced by modern suits of steel, while action is captured by high-speed cameras. Each episode features full-contact jousts in which jousters charge and collide at 30 miles an hour, and every joust is a test of courage and strength requiring nerves of steel. The last man standing takes home the cash as this extreme sport is reborn.
