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.

POSSIBLE ORIGIN OF THESE AERIAL PHENOMENA The Bureau has been advised in the past by OSI that many of the sightings reported to them were determined by investigation to have been of weather balloons, falling stars, meteorological phenomena and other air-borne objects. INFORMATION OBTAINED BY BUREAU LIAISON FROM OSI, WASHINGTON, D. C. RE THE CAPTIONED LATTERS ON OCTOBER 9, 1950. Bureau liaison determined on the morning of October 9, 1950 from OSI headquarters that the investigations of these aerial phenomena are being handled by OSI, Wright Field, Ohio. Their investigation of these phenomena fails to indicate that the sightings involved space ships or missiles from any other planet or country. According to OSI, the complaints received by them have failed to indicate any definite pattern of activity. OSI further advised they are closely following the investigation of the captioned matters, and they will advise this Bureau of any matters of interest. None. The above is for your information.
