In the video, you can hear the guy saying "Oh shit." Maybe because he's 2,000 feet in the air "attached" to pegs.
Take the KLDT tower, which stands at a whopping 1,999 feet, making it one of the tallest structures in the world. Nick Wagner, a project manager of National Tower Controls, is responsible for what happens at the top. When he's summoned to the KLDT mast, his job entails riding a tiny lift for the first 1,900 feet straight up in the air. When he gets to this dizzying height, he has to climb the final hundred feet by hand with nothing but a few carabiners between him and an uncomfortably long fall.
Assuming gravity even still works that high up.
So next time you flick a switch and nothing happens, don't sigh and moan. Give yourself some perspective by remembering that you can at least change the bulb while looking down and still seeing the planet you live on.
