Last week, an Ars Technica writer was struck by lightning. He says that the 911 operators were concerned about whether or not he was wearing shoes at the time, but he didn't think it would make much difference. Apparently, air has a thousand times more resistance than hard rubber. Does this mean that wearing shoes wouldn't do anything?
What about with electrical wiring? I've seen electricity spark through the air before, but I don't think I've seen it go through rubber, especially a greater volume of it. Is there something I'm missing here, or have I just never considered it?
