Bear in mind that most of the deaths from tree felling occur within 10' of the stump. Trunks kicking back or getting wrenched in odd directions when the crown tangles on the way down can make for unpredictable movement in the butt. The best thing to do is to make a hasty retreat from the vicinity of the stump without ever turning your back on the tree.
From my own experience felling in the dense virginia woods I can say that it is very difficult to fully clear the lay for the crown when you are selective harvesting and that often results in crazy swings, kick back (from the tree) - I choose to clear 2 escape paths and use one of them the instant I see the tree start to go.
Same here. I was referring to a tree doing a completely unexpected movement and running in terror. I usually move 8-10 feet off to the safest side and watch carefully, looking up too. Death from above is the danger after the tree is in a committed fall.
