Project 10073 Record — Roslyn Heights, New York, 27 May 1966

This document contains the records for a UFO sighting reported on 23 May 1966 in Roslyn Heights, New York. The witness, a student, observed a single, diamond-shaped object that appeared metallic gray with white lights. The object was described as moving in a westerly direction, dipping up and down in a manner compared to a seagull, and was observed for approximately 90 seconds at dusk. The witness reported no sound. The initial report was filed through military channels, involving the 52nd Fighter Wing at Suffolk County AFB. Major Hector Quintanilla, Jr., Chief of Project Blue Book, subsequently contacted the witness, noting that the initial information was insufficient for a full evaluation and requesting the completion of an FTD Form 164. The witness completed the questionnaire, providing details about the sighting conditions, including the presence of scattered high cirrus clouds and seven-mile visibility. The final analysis by the Air Force suggested that the sighting could be explained by the sun highlighting a seagull at a distance, given the timing at dusk. The file includes the original military teletype, the correspondence from Major Quintanilla, and the completed technical information questionnaire.
