I keep wondering about the guy by the other loader across the fence. He's got the bucket extended up above the peak of the roof of that other building with what looks like an attempt to shield the building in case the limbs go that way. I'm positive if the tree man tops that tree where he is and it falls that way, it's bye bye building, loader, and probably ground man....
In the time it took to get rigged like that, one good tree man in a set of hooks, with a chainsaw could have had most of that dropped without damage to any of the structures in the picture.
I'm not too sure the upper ladder and the man aren't photoshopped in. I don't think he could even get to the second ladder to climb it, even if the bottom of it is nailed down.
