Project 10073 Record Card and Related UFO Reports, May 1964

This document is a compilation of various reports and correspondence regarding Unidentified Aerial Phenomena (UAP) sightings occurring in May 1964. The primary document is a Project 10073 Record Card detailing a sighting in Wheaton, Maryland, on May 31, 1964. In this instance, witnesses observed an object moving from the southeast to the northwest, performing abrupt turns for approximately 25 minutes before ascending. The official conclusion for this specific event was that the object was a balloon. The compilation also includes several other reports of UAP sightings and related phenomena from various locations, including North Lawrence, Ohio; Phoenix, Arizona; Holloman Air Force Base, New Mexico; Wakefield, England; and Las Villas Province, Cuba. These reports describe diverse phenomena, ranging from hovering objects and strange lights to reports of a 'mystery submarine' in Sweden. Additionally, the document contains internal Air Force correspondence regarding the processing of these reports, noting that due to the lapse of time between sightings and report receipt, standard electrical reporting was not always feasible. The document also includes meteorological data requests to assist in the evaluation of these sightings, specifically surface and rawinsonde observations for Washington, D.C., and Flint, Michigan. The overall tone of the document is administrative, focusing on the collection, forwarding, and initial evaluation of UAP reports in accordance with Air Force Regulation 200-2.
