Project Blue Book Case File
Silver Grove, KentuckyJune 1961
Summary
On a June evening in 1961, a resident of Silver Grove, Kentucky observed a shiny object in the sky that changed from red to bright white. The object moved erratically, stopping and starting several times, and eventually faded from view. The witness reported seeing what appeared to be a self-luminous craft that behaved in ways inconsistent with conventional aircraft.
The Air Force investigation produced a report form and witness questionnaire, though the OCR text of the case file is heavily degraded and difficult to read in places. The file appears to contain standard Project Blue Book documentation, including a detailed technical information sheet designed to gather witness observations. Key details are obscured by scanning errors that make precise reconstruction of the investigative findings challenging.
The Air Force's conclusion in this case was listed as "Unknown," indicating that investigators could not definitively explain the sighting through conventional means. However, the file's condition prevents confirmation of specific investigative methods, radar data, or detailed analysis that may have been performed.
The full case file is reproduced below as held by the National Archives across 9 pages of microfilm.
