Project Blue Book Case File
Cincinnati, OhioMay 1957
Summary
In May 1957, a Cincinnati resident observed a single object in the sky for about 14 minutes. The witness described it as round, slightly larger than a baseball, with fuzzy or blurred edges and an orange color with a tail. The object appeared very high in the sky, at an estimated altitude of 10 to 15 miles. There was no sound, and it moved from southwest to north before disappearing below the horizon.
During the Air Force's interview with the observer, investigators learned that the witness held strong beliefs about UFOs and claimed they have a base on the moon. The witness also reported having seen a similar object 11 years earlier near St. Louis, Missouri. The Air Force noted these details in their case file, suggesting they viewed the observer's background and prior claims as relevant context for evaluating the sighting.
The Air Force investigated the sighting as a possible aircraft. The case file indicates evaluators considered it a "probable aircraft sighting based on duration and description," though the record card also lists "balloon" and "probably balloon" among possible explanations. The exact reasoning behind these assessments does not appear clearly in the available OCR text. The Air Force ultimately classified the sighting as unidentified, meaning investigators could not conclusively match it to any known object or phenomenon.
The complete case file, as held by the National Archives, is reproduced below in its 10 scanned pages.
