Rant: That rigging class I took in Tulsa got one thing wrong

We spent a full Saturday going over tag line placement for swinging loads, but nobody mentioned how much a light breeze changes everything when you're working at 150 feet. Last week on a job near the river, we had a 4,000 pound beam start spinning slow and the tag line guy couldn't keep up. Has anyone else found that the textbook method just doesn't cut it outside a wind tunnel?

Watching a 4,000 pound beam start spinning in the wind is nightmare fuel. I can't believe they spent a whole day on tag lines and never brought up wind at height once. At 150 feet even a 10 mph gust acts on that load like a sail, and no tag line guy on the ground can fight physics with his arms. That class set you up to get surprised by something that happens on basically every outdoor pick.
