Project 10073 Record Card — Cincinnati, Ohio, 13 Dec 55

This document consists of a Project 10073 record card and an associated teletype message regarding an unidentified aerial phenomenon reported in Cincinnati, Ohio, on December 13, 1955. The sighting was reported by a civilian witness who observed an ellipsoid object with a blue-white and orange exhaust. The object was reported to be heading west at a rate of 2 degrees in 45 seconds. The teletype message, dated December 14, 1955, provides additional details, noting that the object was observed for 5 minutes visually and with a 15-power telescope, though the record card notes a total observation duration of 40 minutes, which the reporting officer questioned. The object was estimated to be at an altitude of 130 feet, and the witness reported no sound. The weather was described as clear. The report was processed by the Air Technical Intelligence Center (ATIC) and signed off by an operations and intelligence officer named Sidney C. Marlborough Jr. Ultimately, the official conclusion reached by the investigating agency was that there was insufficient data to evaluate the sighting.
