When I was stationed in Korea in the 257th Signal Company (FAST-South), we had a tower climbing section. They took care of all of the American towers south of Taejon. There was nothing as high as this, but I used to watch those guys in amazement. They ran up and down those towers like monkeys on a tree. I heard recently that two of the guys, Mike Stone and Jim Hazel, now own their own company and travel throughout the US doing tower work. Balls of steel.
