Did that actually happen? I know someone who worked at a shortwave (a.k.a. microwave) radio station when that almost happened. They had to shut down the transmitters occasionally to paint the radio towers, but someone had the bright idea that they could just power down long enough for the painters to climb on. Then, when they weren't grounded, they could power it back up during the painting. They actually did a test run with chickens before it dawned on anyone that they would be cooking anything up there!
