Brazil Barra da Tijuca UAP Photographs 1952

On May 7, 1952, journalists Joao Martins and photographer Ed Keffel of O Cruzeiro — Brazil's largest circulation news magazine — were near the Barra da Tijuca coastline when they spotted a disc-shaped craft moving at low altitude. Keffel captured five sequential photographs in approximately 60 seconds showing the craft in different positions and angles. The photographs were submitted to official analysis by the Brazilian Air Force technical division, the Brazilian Navy, and the US Air Force attaché in Rio de Janeiro. All three independent analyses concluded the photographs were genuine and showed an actual object rather than a model or composite. The US Air Force analysis was forwarded to Project Blue Book. O Cruzeiro published the photographs as an exclusive, making them some of the most widely-distributed authentic UAP photographs of the early 1950s. The triple military authentication from two countries on five sequential images remains significant.
