Los Alamos Conference on Aerial Phenomena, 1949
Department of Energy
This document is a transcript of a 1949 conference held at Los Alamos Scientific Laboratory (now Los Alamos National Laboratory), Los Alamos, New Mexico. Attendees included several eminent scientists and physicists, many of whom had contributed to the development of the first nuclear weapons during the Manhattan Project. The purpose of the conference was to discuss and gather hypotheses to account for the nature and origin of a phenomenon involving “green fireballs” that had been reported over a period of several months in the vicinity of the laboratory. The group did not come to a consensus on a likely attribution for the phenomenon, though a leading hypothesis was that the observations may have been 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 the cause, while Dr. Lincoln LaPaz, an expert specializing in meteorics, expressed that “nothing like this, to [his] knowledge, has ever been observed in the case of meteorite drops.”
UAP Reported at Sandia Base, 1948-1950
Department of War
This file contains 116 pages of documentation from the Armed Forces Special Weapons Program (AFSWP) – the direct, post-World War II successor to the Manhattan Project – and from the U.S. Air Force – relating to a series of sightings and investigations in Sandia, New Mexico, from 1948-1950. This file contains 209 sightings of “green orbs,” “discs,” and “fireballs” reported near the military base. Witnesses reported unidentified anomalous phenomena (UAP) maneuvering, flying out of sight, disappearing, or exploding. The documents also include the results of contemporary investigations into residual copper powder found in some areas where sightings were reported. A few of these investigations became the basis for Project Grudge, which collected reports of unidentified flying objects from various other military installations – also included in this collection.
