This file is a US Atomic Energy Commission transcript of a secret conference on aerial phenomena held at Los Alamos Scientific Laboratory on 16 February 1949. A cover letter from the AEC Santa Fe office dated 22 March 1949 accompanies it. Dr. Lincoln LaPaz describes the New Mexico green fireballs, including the Starvation Peak sighting of 12 December 1948 and the 30 January 1949 fall over Texas. He argues they were not conventional meteorites. Edward Teller, Norris Bradbury and others discuss the missing sound and the long horizontal paths but reach no conclusion.
