I was a security officer at a coal mine. I went off patrol to sleep. I was awakened by bright lights shining through the passenger window. When I spun my unit around there was nothing there. But that wasn't the disturbing thing. There was no road where the thing had been, and it was nearly straight down into a gulch. In order for that thing to have shown lights into my window it would have had to be hovering about 30-40 feet off the ground. I never reported it because I was off patrol grid and sleeping on duty. I was very disturbed over this incident and never slept on guard duty again!
