I was driving and noticed people parked and looking in the sky. We watched these lights move slowly with no sound. This area has no planes that fly over our town, Also there was a person who witnessed was a triangle shaped object that blocked out the moon as it passed over. This date is unknown. Date 1989. We where driving to Eagle Butte in a heavy fog and noticed a light coming down, it had 3 lights on the side, my cousin was a witness. It looked like it landed or crashed.((NUFORC Note: Source of report indicates that the date of the incident is approximate. PD))
