Project 10073 Record Card — 12 February 1957

This document is a Project 10073 record card detailing an Unidentified Aerial Phenomena (UAP) sighting that occurred on February 12, 1957, between Valley Forge and Coatsville, Pennsylvania. The witness, a sergeant serving as a guard for Likens Steel, reported observing a single, white, oblong-shaped object while traveling in an automobile. The object appeared to be the size of a pencil held at arm's length and remained stationary in the sky at an estimated altitude of 5,000 feet. The observation lasted for 18 minutes, ending when the witness left the vehicle. The weather conditions at the time were reported as clear. The official evaluation by the Air Technical Intelligence Center (ATIC) concluded that the sighting was likely caused by a balloon. The file includes a teletype communication between military units, including the 646th AC&W Squadron at Benton AFS and the Air Defense Command at Ent AFB, Colorado. A handwritten annotation on the document suggests that the reporting officer felt the provided information was insufficient for a more definitive evaluation.
