DOE UAP D004 Los Alamos Conference on Aerial Phenomena 1949

According to the releasing agency, this file is a transcript of a 1949 conference convened at Los Alamos Scientific Laboratory (now Los Alamos National Laboratory) in New Mexico to discuss and gather hypotheses about a phenomenon involving 'green fireballs' reported over several months in the vicinity of the laboratory. Attendees included eminent scientists and physicists, many of whom had contributed to the Manhattan Project's first nuclear weapons. The group reached no consensus on the cause; a leading hypothesis was that the observations related to meteors entering the atmosphere at a shallow angle and high altitude. Dr. Edward Teller suggested that if not a 'material body,' an 'electron phenomenon' might be responsible, while meteorics expert Dr. Lincoln LaPaz stated that 'nothing like this, to [his] knowledge, has ever been observed in the case of meteorite drops.'
