Project 10073 Record Card — Olmstead AFB, 3 May 1952

On May 3, 1952, at 1752 MST, a sighting of an unidentified aerial phenomenon occurred near Olmstead Air Force Base, Pennsylvania. The incident was reported by two witnesses, one of whom was identified as an ex-pilot, and was subsequently documented via a Project 10073 record card and a Department of the Air Force staff message. The witnesses described a single circular object that appeared red upon approach and turned white as it receded. The object maintained a straight and level flight path, moving from east to west on a heading of approximately 240 degrees. The duration of the observation was 20 seconds. The witnesses noted that the object was at an 'entirely high' altitude and that no jet or rocket exhaust streams were visible. Weather conditions at the time were reported as having unlimited visibility with cirrus clouds present. The report indicates that the witnesses were considered reliable. Despite the documentation, the official conclusion recorded on the card is 'Insufficient Data for Evaluation,' and a note on the record card indicates that the location of the 'DCE' was unknown.
