Watch this video of a worker climbing to the top of a 1,768-foot-tall transmission tower. To reach the top, workers have to occasionally free climb, which means to climb without any sort of safety harness. DO NOT TRY THIS AT HOME. Once at the top, workers can see 55 miles to the horizon.
By comparison, the tallest skyscraper in the United States, Chicago’s Willis Tower (formerly Sears Tower), stands 1,451-feet tall.
