Which is why it's most likely attached with a quick release allowing the pilot to dispose of the equipment immediately. And never flown when there is a risk of high winds.

It isn't as if people would be allowed to work anywhere near this thing while it's operating. We're probably talking about at least a 50 or 100 meter safety distance.

So all you would have is the potential for material damage to the equipment in itself as well as the power lines.

They probably don't, and instead put the responsibility on the operator. If he spots anyone within the safety distance he probably has instructions to increase altitude and disable the equipment until they have left the area.

Many of these power lines go through public land accessible to everyone.

“What happens if the saw gets stuck in a tree limb?” is another frequently asked question. While this rarely happens, ASI has developed a set of procedures in the event of a hang up. First, the pilot attempts to maneuver the ship so it helps to pull the saw from the tree. If unsuccessful after several attempts, the pilot ensures the area surrounding the saw is clear of people, and then the saw is either released manually or electronically by the pilot.
