While the contractor, smucker builders, crew was using a brut post grabber to set the 16th pole of the day for a pole building construction, the 8""x8""x32' pole slipped in the brut pole grabber. It then fell forward knocking down the last pole set, which landed on the brace of the next pole back. the 2x4 wood brace broke and stuck EE in the back of the head as EE moved away.
