Project Blue Book Case File
SE of Louisville, KentuckyJune 1956
Summary
On a June evening in 1956, someone in southeastern Kentucky watched one or two white objects in the sky that moved very fast and appeared to turn and descend. The observer estimated the object or objects were between 5,000 and 20,000 feet above the ground. The sighting took place at dusk.
The Air Force investigated the report, which appears to have been documented in a 19-page file held at the National Archives. According to the investigation summary, the sighting may have been caused by an aircraft that was known to be in the area at the time. No photographs of the object were taken. The case file does not contain a detailed narrative from the witness, and the OCR text is often unclear, making it difficult to extract additional specifics about what was observed or how the investigation proceeded.
The Air Force classified this case as "unknown," meaning the investigators could not identify the object with certainty. The full case file is reproduced below as held by the National Archives in 19 pages of microfilm.
