Aerial saw

I have seen some video previously of this contraption used for trimming trees from a helicopter, but this video from YouTube is better than some. Haverfield Aviation uses the 20-foot long side-trimming saw to trim trees along powerline and gas line right-of-ways. They said it is powered by a compact fuel injected engine and is able to side-trim a 20′ path of vegetation an average of three miles per day on both sides.

It seems that the pilot, in addition to having to have cojones of steel flying adjacent to a power line, would have to have exceptional depth perception to be sure the saw does not drag on the ground, since hitting dirt or especially a rock, would instantly dull the blade.

I’m not sure if this would be feasible to be used on fires if it can only side-trim the branches on trees. Maybe it could widen an established fuel break by 10 to 15 feet on each side.
