Evidently, this happened in France. Below is a quote from anther Frenchman who had more info:
"This have happen in France, and from what I've heard the guy is a strong contract climber. He had a really long day , he wanted to notch the whole thing but the boss said do a last piece. His climbing line was set high to help him work with the big saw, maybe he did not left enought wood... He told he crane operator to wait while he was removing his climbing line from the pick. The crane operator mist understood and pull on the piece before he was untie.... "
I even left his misspellings in
BTW, I have nothing against the French, as I happen to be 100% French Canadian myself
