Watchout for flying power saws

MANITOWOC, Wis. (AP) - March 17, 2014

The American Transmission Company is using an oversized flying saw to trim trees.

The trees are along a high voltage line near the Point Beach Nuclear Plant in Wisconsin.

The company has hired Aerial Solutions.

They use helicopters equipped with rotary saw blades suspended on a 90-foot vertical boom.

The energy transmission company said that using helicopters for tree trimming is more productive and efficient than using ground-based crews.
