Project 10073 Record: Sighting Report - Harvard, Massachusetts, 11 August 1966

This document is a collection of reports and correspondence related to various unidentified aerial phenomena sightings, primarily from 1966. The core of the document is a Project 10073 record detailing a sighting on 11 August 1966 in Harvard, Massachusetts, by a military witness who was an ex-Civil Air Patrol cadet. The witness reported a disk-shaped object flying under the cloud cover of a severe thunderstorm. The official conclusion for this specific incident was that a cloud was responsible for the observation. The document also contains numerous other reports, including correspondence from individuals like Keith Bender and others, describing various sightings of lights and objects in the sky. Many of these reports were evaluated by the Air Force, often concluding that the sightings were satellites, meteors, or other conventional phenomena. The correspondence includes letters from citizens seeking information or reporting their experiences, and the Air Force's standard responses, which often emphasize the lack of sufficient data for a scientific investigation and the importance of reporting sightings promptly to the nearest Air Force installation. The document also includes internal Air Force communications regarding the analysis of balloon debris and the handling of UFO reports, reflecting the administrative processes of Project Blue Book during this period.
