Project 10073 Record Card and Air Intelligence Information Report — Millheim, Pennsylvania, 13 August 1952

This document consists of a Project 10073 record card and an Air Intelligence Information Report regarding a sighting in Millheim, Pennsylvania, on August 13, 1952. A high school student reported observing a yellowish, stationary object at approximately 2130 EDT. The object was estimated to be 20 times the size of the brightest star. The witness observed the object for 5 to 10 minutes before it faded out. A second witness, an adult male, corroborated the sighting while driving on a highway near Spring Mills, Pennsylvania. He described the object as moving at approximately 35 mph on a course parallel to the highway, maintaining a straight and level flight path before making a sharp turn to the South and disappearing. The weather was reported as clear with 15-mile visibility. Intelligence officers noted that while there had been heavy meteor activity in the area, the object could not be conclusively defined as an astronomical phenomenon. Furthermore, while the possibility of an aircraft was considered, the duration of the observation (10 to 20 minutes) was cited as a factor that made that explanation less likely. The report concludes that the object remains unidentified.
