SUBJECT: FLYING SAUCERS

DATE: October 9, 1950
PURPOSE
To advise you of the most recent information known to the Bureau concerning the captioned aerial phenomena.
BACKGROUND
You will recall that on August 23, 1950, I furnished to you a memorandum regarding Project Twinkle set up by the Department of the Air Force, with the assistance of Land-Air, Inc., at Vaughn, New Mexico, for the purpose of obtaining data regarding these unusual aerial phenomena which had been seen in the vicinity of sensitive installations in New Mexico. To date the Air Force has not advised us of any new developments in connection with this project.
Dr. Anthony O. Mirarchi, Project Engineer of Project Twinkle, has been contacted by the Albuquerque Office and arrangements have been made in order that the Bureau will be advised in the event any information relative to these phenomena indicates any jurisdiction on the part of the Bureau.
According to Bureau files, an average of approximately three or four complaints have been received per month from June through September. These complaints were brought to the attention of OSI. A review of Bureau files does not indicate that there has been any increase in the sightings of these phenomena during or as a result of the war in Korea.
JURISDICTION FOR INVESTIGATION OF THESE PHENOMENA
You will recall the investigation to obtain information concerning these aerial phenomena is the jurisdiction of the Department of the Air Force. The Department of the Air Force is aware of our jurisdiction in matters relating to espionage, sabotage and internal security, and we have contacted OSI and requested them to advise us of any developments in connection with these phenomena which would be of interest to us as a result of our jurisdiction.
