Extraordinary video showing transmission workers scaling the terrifying height of a broadcast antenna.
The six-minute film, shot using a helmet camera, follows the progress of two engineers as they scale a 1,768 ft pylon in the US.
In case anyone is in doubt about the height to which the workers climb, the top of the antenna shown in the film is higher than Chicago’s Willis Tower (formerly the Sears Tower), the tallest skyscraper in the US.
