We were delivering newspapers in downtown Littlestown,Pa. on the eastern edge of town at about 4:45 AM,when we came to a stop sign facing south.At this time,we observed a configuration of white lights in a diamond shape with all the lights equidistant apart.The lights were solid white and at the top and bottom there was an additional white light that pulsated together like a heartbeat.All we could see was the lights.At first,we thought it was a celltower because they were stationary.After further thought we realized celltowers have RED lights,NOT white.We returned to the site about 5 minutes later and the lights were gone.We were really confused now.Why,if this was a celltower,did the lights go out?We returned to the site the next day after sunrise and found nothing but an EMPTY FIELD.NO structure,NO ANYTHING!!!To this day it bothers me greatly.I am a man who uses deductive reasoning to figure things out.THERE IS NO EXPLANATION FOR THIS.Whatever this was,it made no noise at all.It was approximately 400 feet from us and maybe 200 feet in altitude.I will never forget this experience EVER!I remember it like it happened yesterday.It looked like this: . . . . . .
