This declassified document is a March 22, 1949 letter from the Security Operations Branch of the U.S. Atomic Energy Commission's Santa Fe Directed Operations. It forwards a transcript of a Conference on Aerial Phenomena held at Los Alamos Scientific Laboratory on February 16, 1949. At the conference, Dr. LaPaz described the green fireballs, including his own Starvation Peak sighting of December 12, 1948, and argued that they were not conventional meteors. Dr. Teller and others discussed why the fireballs made no sound, and no conclusion was reached.
