I was traveling from Mississippi to Illinois going north on Route 412 near Dyersberg TN. GPS showed I was about 14 miles south of Route 155. Two saucer shaped flying objects with dome on top flew across the highway about one-eighth of a mile in front of me. It was daytime, but somewhat cloudy and dark, so the silver metallic discs were quite noticeable. They were moving very fast so sighting was short. They disappeared over the top of the tree line on my right. I felt sobered and nervous. I called the two people in this world who would believe me, my wife and my son.
