I'll say again, cool of you to post the video.
Out of my 20 or so videos that I have edited in my head that I want to put together sometime, one of them is one that shows mistakes and notes climbers that got killed.
I have a mistake on film with me from years ago, might be on a tape, a butt of a limb bumped me in the face. Only busted my lip a little, but looks kind of violent. Crane pick from a tree that fell on a house. I had the two sling tensioned wrong. 2006 maybe?
I had a big log try to take my 460 once. I put the tip of the saw a little too far, chain stayed in that kerf. I had a loop runner as the layard too, and it was attached to my saddle. Maybe 2000 lb log. Up about 15 feet high. As it hinged over, i felt the saw was going, my right hand went fast to the biner and I suprised myself, I got the biner off before the loop runner got tight, just then the saw pulled out. That would have really hurt, probably would have been the chainsaw chain that would have been the weak point there. That's actually on video too, doesn't show it great until you watch in slow mo.
