On January 19, 1973, a young man in Gaffney, South Carolina, had an encounter with what he described as a domed, saucer-shaped craft hovering over the highway. It’s one of the more widely known UFO incidents. That makes it only natural that South Carolina was later to become home to the UFO Welcome Center.
