they do it alot in cali, transmission lines are not joke, i use to work on them, if you pulled over to watch he has a 4ft metal rod he hangs out to energize him and the heli, the arc just jumps out at it from around 4-5ft away and is so bright you cannot look at it, they also have attachments that clip on the heli to trim trees, pretty cool stuff, he also has a cradle and clips, he can actually use it to clip on the transmission lines and it looks like a hammock and it has rollers, just pulls himself from one pole to the next...you can't get health insurance though, and one out of every two dies. pays in the 200k's annualy
