File 1187 - Rio de Janeiro, Brazil - May 7, 1952

This document, identified as File 1187, serves as a photographic record of an unidentified aerial phenomenon observed in Rio de Janeiro, Brazil. The primary documentation consists of a cover sheet dated May 7, 1952, which explicitly notes the inclusion of five photographs. The subsequent pages of the document contain these photographic images, which depict a disc-shaped object appearing in the sky above a landscape. The images show the object from various angles and distances relative to the terrain. While the cover sheet provides the date and location of the incident, the document contains no narrative report, witness testimony, or official analysis regarding the nature of the object. The images themselves are the sole content provided, documenting the visual appearance of the object as it was captured on film. One page includes a label reading 'Rio de Janeiro, Brazil - June 1958', which appears to be a later annotation or reference, potentially conflicting with the May 1952 date on the cover sheet. The document provides no further context, investigation results, or conclusions regarding the origin or identity of the object.
