American climber Alex Honnold has successfully scaled a Taiwan skyscraper without a rope, harness or safety equipment. The building, named Taipei 101 for the number of its floors, stands at 508m (1,667ft) of steel, glass and concrete and is designed to resemble a stick of bamboo. Honnold is renowned for being the first person to climb El Capitan, the vertical granite cliff in California's Yosemite national park - also without ropes or safety gear. The climb was originally set to take place on Saturday but was delayed by wet weather. His ascent in Taiwan's capital was streamed live on Netflix, which said there would be a delay on the live feed should the worst happen. Honnold completed the climb in one hour and 31 minutes and celebrated the achievement with one word: 'Sick.' His time more than halves the record of the only other person to scale the tower. Alain Robert, a Frenchman who called himself 'Spiderman', made it to the top of Taipei 101 - at the time the world's tallest building - in four hours. Honnold was congratulated by Taiwan's Vice President Hsiao Bi-khim, who expressed her own nervousness at watching the climb. Upon reaching the top, Honnold was warmly welcomed by his wife, who had been concerned about the challenging conditions. As Honnold climbed, spectators at the 89th floor cheered him on from behind the glass, capturing the moment on camera. Honnold's extraordinary climbs have gained him international recognition, particularly following the success of his Academy Award-winning documentary, 'Free Solo,' which chronicles his ascent of El Capitan.
