Project 10073 Record - Warrington, Pennsylvania - 21 November 1966

This document is a Project 10073 record detailing a civilian sighting of an unidentified aerial phenomenon in Warrington, Pennsylvania, on November 21, 1966. The witness reported observing a single, round, silver-colored object at approximately 10:00 PM. The object was described as traveling in a level and straight path toward the northeast at a low altitude, estimated at 50 feet. The observation lasted for five minutes, during which the witness noted a hissing sound. The object eventually disappeared from view by descending behind trees. The official conclusion recorded by the Air Force is that the object was a possible aircraft. The report includes a completed U.S. Air Force technical information questionnaire, which provides additional details such as the weather conditions being clear and dry, and the observer's estimation of the object's speed at 20 miles per hour. The investigation involved coordination with personnel at NAS Willow Grove and an investigator named Robert N. Solleday.
