Re, above...
I spent about 9 months working for a company that was removing old twisted copper wire from poles up in the mountain areas, and replacing it with modern aluminum wire. (Often, replacing the poles also.)
Luckily I found a better paying job and moved on without ever having or seeing an accident on the lines. Unfortunately, a few months later one of the guys was working in the bucket and was caught in a flashover between a hot wire and a ground. He probably died fast, but the crew had to watch as the body and bucket burned up in the wires while waiting for somebody downline to kill the power to that section.
A couple guys on the crew quit after that due to how freaked out they were after having witnessed it. One of them is a life-long friend of mine, and it was pretty painful to listen to him tell the story. You could really tell it got into his head.
Also... add this to my list.
F**K this:
