Incident #19 Sighting Report — Dayton, Ohio, 20 October 1947

This document details Incident #19, a sighting of two unidentified objects over Dayton, Ohio, on October 20, 1947. The witness, whose name is redacted, reported observing two 'cigar-shaped' objects flying in horizontal formation, separated by approximately one city block. The objects were described as silver, reflecting light, and moving at a 'very fast' speed at a very high altitude, estimated between one and five miles. The witness noted that the objects left exhaust trails resembling a slight trace of steam. The weather was described as cloudless. The report includes a checklist and a narrative summary of the event. An investigation by the Air Technical Intelligence Center (ATIC) concluded that the witness's testimony was reliable. While the report briefly considers the possibility that the objects were a 'double fireball,' the investigator dismisses this as highly unlikely and concludes that the objects remain unidentified. The document also includes an index of Dr. Hynek's evaluations from the Project Grudge report, which categorizes various incidents based on their likelihood of being astronomical or otherwise explained.
