With the 362-foot (110 m)-tall antenna/mast, the highest point of the North Tower reached 1,730 feet (530 m).[91] Chicago's Sears Tower, finished in May 1973, reached 1,450 feet (440 m) at the rooftop.[93] Throughout their existence, the WTC towers had more floors (at 110) than any other building.[91] This number was not surpassed until the advent of the Burj Khalifa, which opened in 2010.[94][95] Each tower had a total mass of around 500,000 tons.[96]
Philippe Petit Philippe Petit (French pronunciation: ​[filip pəti]; born 13 August 1949) is a French high-wire artist who gained fame for his high-wire walk between the Twin Towers of the World Trade Center in New York City, on the morning of August 7, 1974.[1] For his unauthorized feat 1,350 feet (400 metres) above the ground – which he referred to as "le coup"[2] – he rigged a 450-pound (200-kilogram) cable and used a custom-made 26-foot (8-metre) long, 55-pound (25-kilogram) balancing pole. He performed for 45 minutes, making eight passes along the wire. The following week, he celebrated his 25th birthday. All charges were dismissed in exchange for him doing a performance in Central Park for children.
