Public-domain United States government records (USAF Project Blue Book, NARA microfilm publication T-1206). Machine transcription from microfilm scans — typewritten bodies read well; stamps, marginalia and handwriting imperfectly. Pages marked poor legibility await re-examination. Source scans are linked unaltered on every case file.
