Project 10073 Record Card — Georgetown, Massachusetts, 5 July 1955

This document is an Air Intelligence Information Report concerning an unidentified flying object sighting reported by Mr. George G. Tyler in Georgetown, Massachusetts, on July 5, 1955. The report, processed by the 32d Air Division (Defense) and forwarded to the Air Defense Command, details a six-second observation of a single, disk-shaped object described as resembling an 'emery wheel.' The object was estimated to be approximately 230 feet in diameter and was observed traveling in a circular flight path from East to North at an extremely fast rate of speed, accompanied by four vertical silvery-white streaks. The witness, identified as a registered pharmacist, was considered reliable by the Operations Officer of the Manchester, N.H. Filter Center. The official conclusion reached by the military investigators was that the sighting was likely an atmospheric or optical phenomenon. Specifically, it was suggested that the observer witnessed the reflection of sunlight off a high-flying jet aircraft and its associated contrails. This conclusion was supported by a check with the COC Weather at the Air Defense Command, which confirmed that there were no temperature inversions at the time of the sighting that might have caused anomalous refraction. The report includes a detailed diagram drawn by the post supervisor, Mr. James Maropoti, which illustrates the object's flight path relative to the observer's position and the local geography. The documentation consists of several standard forms, including the Project 10073 Record Card and the UFOB Index Card, which summarize the incident and the subsequent evaluation. The file emphasizes that the information provided by the witness was considered credible, despite the final determination that the object was likely a conventional aircraft.
