Project Blue Book Case #4399. On September 14, 1956, a bright object was observed near Highlands, North Carolina — a mountain resort community at approximately 4,100 feet elevation in the Blue Ridge Mountains near the South Carolina and Georgia borders. Highlands sits on a plateau at the southern end of the Appalachian chain, with dark skies and dramatic mountain terrain.
The remote mountain setting provided excellent observation conditions with minimal light pollution. The case was classified "Unknown."
