Project Blue Book Case File
Cincinnati, OhioJune 1961
Summary
On a June evening in 1961 in Cincinnati, Ohio, someone observed an unidentified object in the sky. The Air Force investigation file contains a detailed witness questionnaire and evaluation form, but the OCR scan quality makes most of the specific details illegible or heavily garbled across the seven pages.
What can be read from the cover sheet indicates the sighting was ground-based and visual. The evaluation form notes two possible conclusions: "Probably Balloon" and references to other potential explanations, though the OCR text is too unclear to state with certainty what the Air Force concluded. The file preserves a standard U.S. Air Force Technical Information Sheet and multi-page witness questionnaire, suggesting the case was documented according to Project Blue Book procedure, but the handwritten responses and OCR limitations prevent a reliable reconstruction of what the witness saw or how investigators analyzed the report.
The full case file, as held by the National Archives, is reproduced below in 7 scanned pages.
