[Rome2000]

Had a guy on top of a 40 story building under construction get blown off because he was holding on to a 4x8 sheet of plywood and a gust came. He held onto to the board and was blown back in 3 story's below.

The guy held the board so tight his fingernails were embedded in the wood and were ripped out of his hand.

He never came back to work again.

That particular kind of event was featured in a "Mythbusters" episode. Their conclusion was that hanging onto a piece of plywood was about as good as hanging onto a rock. It must have been a VERY strong gust of wind.
