High Voltage Power Line Repair

I was watching an episode of the program World's Toughest Fixes on the National Geographic Channel about working on high voltage power lines. The power company PSEG let the host of the program actually do some of the work on the lines including live line repair from helicopter. This video is a clip from the show on the program's website. Each episode is about a major repair that the host participates in. On a recent episode they were installing a new diesel engine generator in a cruise ship. I like the shows of the theme: world's largest crane, building the world's tallest building, the world's largest digging machine, etc, etc....
