Project 10073 Record — Thornwood, N.Y. Sighting, 25 April 1966

This document contains a Project Blue Book sighting record (Project 10073) concerning an unidentified aerial phenomenon observed on the night of April 25, 1966, in Thornwood, New York. The primary witness, a 21-year-old female, reported observing a solid object with four evenly spaced, yellow-orange oval lights. The witness stated the object was approximately 1500 feet in the air, traveled from the north to the southwest, and moved faster than a jet plane. The witness emphasized that the object made no sound and did not resemble any airplane or helicopter she had seen before, despite living near the Westchester County Airport. The observation lasted between 15 and 20 seconds. The witness's husband also observed the object through field glasses. The witness reported the incident to the Mt. Pleasant Police and subsequently to the Project Blue Book office in Washington, D.C. The Air Force responded on May 10, 1966, via Major Hector Quintanilla, Jr., stating that the initial letter was insufficient for evaluation and requesting the completion of a formal FTD Form 164. The completed questionnaire provides detailed sketches and descriptions, noting that the lights were not blinking or revolving and that the object's edges appeared dim. The official conclusion recorded on the summary sheet is 'Aircraft (possible).'
