Project Blue Book Case File
Duluth, MinnesotaMay 1961
Summary
The OCR quality of this case file is too poor to support a reliable summary. While the metadata indicates an observation in Duluth, Minnesota in May 1961 that the Air Force evaluated as "unknown," the document pages are severely degraded and largely illegible. Key details about what was observed, by whom, when exactly, and how the investigation proceeded cannot be confidently extracted from the garbled text. The full case file, consisting of 8 pages as held by the National Archives, is reproduced below.
