Project 10073 Record Card and Observer Questionnaire — Navarre, Minnesota, 23 August 1952

This document contains a sighting report filed under Project 10073 regarding an unidentified aerial phenomenon observed in Navarre, Minnesota, on 23 August 1952. The witness, a machinist inspector, reported observing a single, silver, perfectly round object, approximately the size of a golf ball, while at a filling station. The witness stated they were filling a car with gas when they glanced up to watch two P-51 fighters and noticed the object. The witness described the object as moving at a 'terrific rate of speed' and performing erratic maneuvers that were unlike any conventional aircraft they had ever seen. The observation lasted approximately 5-6 seconds. The witness noted that there was no sound associated with the object and that it had no visible distinguishing marks. The report includes a completed 'Observers Questionnaire' where the witness provided details on their location, the weather conditions (clear, dry, and warm), and a sketch of the object's motion. The witness also indicated that they were not alone at the time of the sighting and that others had seen it as well. The official evaluation of the report by the Air Technical Intelligence Center concluded that there was insufficient data for a formal evaluation. A cover letter from the 31st Air Division at Fort Snelling, Minnesota, dated 28 August 1952, forwarded the report to the Air Technical Intelligence Center at Wright-Patterson Air Force Base in accordance with Air Force Letter 200-5. A follow-up letter from the Air Technical Intelligence Center to the witness, dated 4 September 1952, acknowledged receipt of the report and provided a questionnaire for further standardization of the data.
