You can see the Pilot of this Helicopter leaning out into the bubble window as he looks down at 100 feet of tree trimming tool hanging under the helicopter. The tree trimmer has ten large saw blades rotating at very high speed at the bottom of the long drive shaft. The pilot works a two hour shift then has to land and rest for an hour.
This helicopter is used to trim trees on each side of a high voltage electric line. I would think that flying a helicopter is challenge enough but this pilot has to fly, watch the trees, ground and electric lines all at the same time. All identifying information has been removed from the helicopter to protect the company and pilot.
