Incident #51 Sighting Report — Oswego, Oregon, 3 September 1947

This document contains records pertaining to Incident #51, which occurred on 3 September 1947 in Oswego, Oregon. A single witness, identified as a housewife, reported observing twelve to fifteen round, silver-colored objects at a high altitude at 1215 PST. The report includes a standard check-list for unidentified flying objects, which notes that no sketches or photographs were taken and that the witness was observing a local plane flying overhead at the time of the sighting. The evaluation of the incident, conducted under the auspices of Project Grudge, concludes that the information provided is insufficient to reach a definitive conclusion. The report highlights the limited nature of the data and expresses surprise that only one witness reported the event, despite it occurring in a city. The evaluators suggest that if the objects were not ordinary aircraft at a great distance or a cluster of balloons, the incident should be analyzed in conjunction with other reports of groups of unidentified round or discoid objects that occurred in the same geographic area, specifically referencing incidents #5-9 and #12-16. The document also includes an index of Dr. Hynek's evaluations of various incidents, categorizing Incident #51 under the classification of 'Evidence offered suggests no explanation' within the broader category of 'Non-astronomical, with no explanation evident.'
