can't pay me enough money to do this.

If you put me on the top of that thing and said climb down and all the money in the world is yours, i would be as good as the cat that climbed the tree next door.
I would think the thing moves in the wind?????
How about when you have to go to the rest room???
The only way i could climb that high, would be inside a tube, that had the floor close under me as i climbed the ladder.
I will have to say that those guys have total confidence in there ability.
I don't think i could even go up a set of stairs out in the open like that.
