Project 10073 Record Card: Cleveland, Ohio Sighting (12 August 1963)

This document collection details the investigation of a physical object recovered in Cleveland, Ohio, on August 12, 1963. A civilian observer reported that while cleaning her yard during a rain shower, she went inside to avoid the rain. Upon returning outside after the rain stopped, she discovered her son playing with an object that had allegedly fallen to the ground, leaving a half-inch indentation. The object was subsequently turned over to the Aeronautical Systems Division (ASD) at Wright-Patterson Air Force Base for analysis. The investigation, documented under report MY 63-37, involved spectrographic and X-ray diffraction analysis. The laboratory concluded that the object was composed of salt crystals (sodium chloride). Correspondence from Allan J. Manak of the American UFO Committee to Dr. J. Allen Hynek indicates that the committee was interested in the incident and sought to provide the fragment to the Air Force for analysis. The records include a project record card, an evaluation report from the Materials Physics Division, and personal correspondence regarding the incident's documentation.
