What they don't really show, there, are the two main dangers involved with climbing those towers. One is radiation from the various microwave dishes, but the second is the rather alarming swaying that occurs as you near the top. The towers themselves are not substantial and are designed to sway, but they don't feel safe when you're atop one - even a much smaller one. And when you look down, the human propensity for making any height seem lethal really kicks in, and the diminishing size of the tower below you makes it feel as though you're standing on a needle. Not nice...
