I have a strange feeling in my stomach watching this. I can imagine being paralysed by fear half way up and unable to move.

I thought this was footage of Newt Gingrich trying to regain the moral high round.

That gave me the collywobbles.

You've got to be missing something very fundamental to do that for a living.

Quite astonishing.

Assuming it's the same footage (and I think it is), this was posted on a blog very briefly, and got taken down - they got into serious trouble because it shows them working without the safety line attached. Apparently it gets in the way when they're working.

I can hardly bear to watch it - a few seconds of that and I can feel a certain part of my anatomy shrinking.

in my lower body is now in a state of spasm. Seriously butt-clenching stuff.

"And The Wichita Lineman is still on the liiiiiiiiiiiiinnnnne!!!!!!!"

... one of them was going to say "I forgot the screwdriver!"

Blimey, my palms are still sweaty.

What happens if one of them has to 'go'?

at one of my work places to demonstrate the importance of designing safety into construction projects, especially safety for future maintenance workers. Even if they were using the safety line, look how many times they have to pull themselves up, over or around something. Check also the falling object hazards the second guy faces.
