Lépcső a mennyekbe - Stairway to Heaven

This is for the masochists among you, who fear heights, yet cannot resist watching clips of height climbers. This was shot from a camera mounted on the (hard) hat of a technician. There's this team of people who do repair work on antenna towers, taller than the Sears Tower. The repairmen are climbing up essentially with nothing to protect them from lightning, slippery steps, attacks of dizziness, nasty birds, etc. In short, if they slip, that's it. And it's a long way down. But they're quite casual about the whole thing.
Notice that the main part of their work begins after this clip ends. The climb is the getting-to-work part.

EDIT JULY 2011: A lot of viewers recommend coming down by using a parachute. Please know that this would be very dangerous! First of all, carrying the equipment all the way up with you would seriously hamper your movements and weigh you down. Then, you would need to jump far, far away from the tower and its cables and protrusions, otherwise you run the risk of the parachute being ripped or not opening. (Parachutes open rather widely!)

EDIT SEPTEMBER 2011: And, yes, they're wearing hard hats because they wanna protect their heads when climbing up. Even a small hit on your (bare) head can make you dizzy and lose your balance.
