Gemini 7 Transcript, 1965
NASA
Gemini 7 was the tenth crewed American spaceflight. This document is a transcript of communications between the flight crew, Astronauts James “Jim” Lovell and Frank Borman, and the Manned Flight Center (now known as Johnson Space Center) in Houston, Texas. The transcript begins with Borman’s report of a “bogey,” contemporary nomenclature for an unknown aircraft, as well as a debris field. Borman described the debris field as consisting of “very, very many […] hundreds of little particles.” He estimated the particles’ distance from the spacecraft to be four miles. Lovell described observing a “brilliant body in the sun against a black background with trillions of particles on it.” This document also includes handwritten notes documenting the encounter, annotated with the phrase “UFO Sighting by Borman” in the top right corner.
