The Flying Saucer, Bulletin No. 7, August 1957

This document is Bulletin No. 7 of the Centro de Pesquisa dos Discos Voadores (CPDV), dated August 1957, edited by Auriphebo Berrance Simoes. The primary focus is the 'silvery rain' incident that occurred in Campinas, Brazil, on December 20, 1954. The bulletin details the evolution of the investigation into this event, where a witness reported three spinning, gray, circular objects hovering over her backyard and dropping molten metal. Initial reports, based on an examination by a local chemist, Dr. Visvaldo Maffei, claimed the material was 88.91% pure tin with no traces of other metals, suggesting a non-earthly origin. However, subsequent investigations by Professor Charles A. Maney and others revealed the material was likely a tin-lead alloy, similar to solder. The bulletin documents the confusion, conflicting reports, and the editor's own admission of being misled by initial, unverified claims. It also includes correspondence from Dr. Olavo Fontes regarding attempts to have the material analyzed by the USAF. The document serves as a record of the internal debates and investigative challenges faced by UFO researchers in Brazil during the 1950s, highlighting the difficulty of verifying physical evidence and the tendency for initial, sensationalist claims to be corrected by later, more rigorous analysis. Additionally, the bulletin contains reports of other sightings in Brazil, including 'fire-balls' and cigar-shaped objects, and discusses the organizational struggles of the CPDV and the potential for cooperation with international groups like NICAP.
