Alex Honnold has sensationally scaled one of the tallest skyscrapers on Earth with only a bag of chalk — and no ropes or safety gear.
The American rock climber took one hour, 31 minutes and 43 seconds to complete the hair-raising stunt on Saturday evening. On Friday night, just minutes before Skyscraper Live was due to air on Netflix on Friday (January 23), it was announced that the special had been postponed due to wet weather conditions in Taipei.
