Project 10073 Record Card: Williams Bay AFS, Wisconsin, 5 November 1957

On 5 November 1957, at 0500Z, a sighting of an unidentified aerial phenomenon was reported at Williams Bay AFS, Wisconsin. The report, filed under Project 10073 (UFOB 1581), involved three military personnel: A/2C Walter L. Kelly, A/3C Harold Erwin, and Capt Herman Blohm. The witnesses described a single, small, round object that exhibited a flashing red and white light. The object was initially observed to be stationary before it moved upward. The weather conditions at the time were reported as clear. No radar contact was made, and no physical evidence was recovered. The official conclusion reached by the evaluating agency was that there was insufficient data to determine the nature of the object. The investigating officer, Capt Blohm, noted that the sighting was likely a confusion with a rotating beacon on a tower or building, and he explicitly criticized the quality of the report, stating that for military men, the reporting was very poor. The document includes a standard Project 10073 record card and a teletype message detailing the description of the object and the circumstances of the observation.
