I too recall watching a cable channel on the use of a helicopter for high voltage line repairs. However it was not using a single person pilot/lineman that can leave the helicopter unattended. I am prepared to recant my opinion that this is not being done at this time with some kind of proof. Surely such an amazing feat would have tons of articles and videos demonstrating itIf I remember correctly, the one-man-helicopter method of working on high power lines was demonstrated on the History Channel, right at the end of the episode of Modern Marvels, or whatever series that epidode was a part of. It might even be possible to find a transcript on the internet. I found a transcript of "Triumoh of the Nerds".
