On August 7th 1974, a young Frenchman called Philippe Petit stepped out on a wire suspended between New York's twin towers, then the world’s tallest buildings. After an hour dancing on the wire, with no safety net or harness, he was arrested and thrown into an underground prison. Until that moment no one but Petit and his team of accomplices, who had spent months planning their illegal 'coup' knew anything about it. Born out of a dream and an idea, Petit and his team would have to find a way to bypass the WTC’s security; to smuggle the wire and rigging equipment into the towers; to suspend the wire between the two towers; to secure the wire at the correct tension to withstand the winds and the swaying of the buildings; to rig it secretly by night – all without being caught. Not to mention the walk itself.
