Documents / FOIA release
This part of the Federal Bureau of Investigation's UFO file collects FBI and Air Force correspondence from about 1950 to 1953. It includes an Air Force OSI district summary of aerial phenomena in New Mexico from December 1948 to May 1950, which reports that green fireballs occurred near sensitive installations and remained unexplained. It also holds a 1950 sighting of an orange sphere by a New Haven chemical engineer, a report from jet pilots near Fairbanks, a Los Alamos reporting form, and 1953 memos on sighting tips that the FBI passed on without investigating.
