Witness: Events of the 20th Century tells the dramatic, revealing and sometimes moving stories that lie behind the headlines. These are the tales that have caught the public's attention and imagination across the world: tales of bravery and disgrace, of destruction and innovation, of despair and hope.1. The Crazies For some a compulsion, a drug that needs the rush and adrenaline that skirting on the precipice of danger brings. For others a predicament which forces a death-defying show of bravery. These are crazies, the foolhardy and the genuinely heroic that have been involved in stories that have truly thrilled us.2. The Adventurers From the men who jump ravines on motorbikes and ski down mountains for sheer fun, to those leaping from burning buildings or landing stricken aircraft to those who explore to the ends of the earth, these are characters who've been to the very edge.
