Rectangular object flying low, slow with red light flashing.I was driving east on 84 about 30 miles west of Snyder, I turned to my left and saw just above the road a rectangular object with a red light flashing under it. It was flying low and traveling west. I never noticed the object as it was approaching me and only saw it when it was above and to the left of me. I tried to watch it while driving at the same time. I was startled and wanted to turn around to follow it but was too scared. I instead pulled to the side of the road to watch it. The low speed, bright flashing light, and object flying low never changed. I continued to watch it until it left my sight.
