Project 10073 Record Card — 13 August 1956, Hermanville, Michigan

This document is a Project 10073 record card detailing an unidentified aerial phenomenon sighting that occurred on 13 August 1956, approximately 10 miles north of Hermanville, Michigan. The report describes a single object observed for a duration of 20 seconds. The witness characterized the object as round with a flat bottom, metallic and silver in appearance, and estimated its size to be between 18 and 20 feet. The object was reported to have moved toward the south before disappearing. The record card indicates that the observation was made via ground-visual means. The official conclusion reached by the evaluating agency, ATIC, was that there was insufficient data for a proper evaluation. The report explicitly notes that no specific bearings, elevations, maneuvers, or other basic data were provided by the source, rendering the incident impossible to classify further. The document includes handwritten annotations, including a note stating 'I agree' and 'Insufficient Data for any conclusion,' as well as rough sketches indicating elevation and azimuth measurements, though these remain largely contextual and do not provide definitive technical data.
