Project Blue Book Case #2692. On August 27, 1953, a bright object was observed over Greenville, Mississippi — a city on the banks of the Mississippi River in the heart of the Delta. Greenville sits in the flat, alluvial plain of the Mississippi Delta, with terrain so level that aerial objects are visible for enormous distances.
Greenville was home to Greenville AFB, a pilot training installation. The base's training aircraft were well-known to residents. The object did not match any training flight. The case was classified "Unknown."
