Project 10073 Record Card — Manhasset, New York, 5 July 1955

This document is a Project 10073 record card and associated teletype correspondence regarding a UFO sighting reported on July 5, 1955, in Manhasset (Roslyn), New York. The primary witness observed a bright light moving from west to east at an estimated altitude of 15,000 feet. The observation lasted between ten and twelve seconds. The witness, who was on a terrace in Roslyn, noted that the object had no running lights and was moving too fast for an airplane. The weather conditions at the time included local thunderstorms and a cloud layer at 20,000 feet, with a haze layer over the area. The report was processed by the 26th Air Division in Roslyn and forwarded to the Air Technical Intelligence Center at Wright-Patterson Air Force Base. The official conclusion reached by the investigating authorities was that there was insufficient data for a proper evaluation, citing the brevity of the sighting and the lack of additional information. The document also references a concurrent investigation by the Nassau Police regarding a burning object found in a tree in Flower Hill, New York. This object was identified as a lightbulb and battery, likely remnants of weather apparatus, and was reported by a Mr. Crowe. The military investigation concluded that the primary sighting did not warrant further follow-up due to the lack of significant data.
