Sorry this took so long, but I found out more info on the story.
Apparently the guy who got hurt is working for me now... which I didn't realize until the other day.
Alright, the company he was working for was TCOT. The guy has MANY years of experience with the business, so he was no newb when this happened. The way he tells it, there were SEVERAL people on the jobsite, but he doesn't remember exactly what happened. He said that the last thing he really remembers was that he was tying on a chainsaw for a climber who also had a polesaw up in the tree. He said somebody else was either taking a shot with a throw weight, or was messing around with a stuck bag. He had to spend 2 days in the hospital because of the damage... I think it hit him in the bridge of his nose. Then he went back another day later in the week when a surgeon installed some kind of metal piece into the bridge of his nose.
