Project 10073 Record Card — Cleveland, Ohio, November 28, 1955

This document consists of a Project 10073 record card and a related military teletype message concerning an unidentified aerial phenomenon reported in Cleveland, Ohio, on November 28, 1955. The sighting, which occurred at 2232Z, involved a single object described by a civilian witness as being dark grey in color, shaped like a wing, and roughly the size of a single-engine aircraft. The observation lasted approximately 20 seconds at an altitude of 1,000 feet under clear weather conditions. The witness reported that the object made no sound. The military teletype, dated November 30, 1955, confirms the details of the report, noting the object's structure resembled a wing. The report was processed by the 662nd ACWRON at Brookfield AFS, Ohio, and forwarded to various commands, including the Air Technical Intelligence Center at Wright-Patterson AFB. The final assessment recorded on the project card is that there was insufficient data for a formal evaluation. Additionally, the document includes a separate, unrelated case report (Case 171) from Hong Kong, dated November 28, 1955, involving a bright light observed near Lyemun Pass, which was dismissed by an editorial note as a meteorological balloon.
