Disappear. i am a professional driver and was on my route when this occurred, at 9:03 pm. the object was a similar color to a cool-white led light. the time span was too short to even film, but i immediately called my wife to tell her what i'd seen right after. it was a bizarre thing to watch. it just stopped in it's path, went from being perfectly even with the horizon to being at a 45 degree angle and went straight down and out of sight.
