Letter to Director April 4, 1949
SA-100- 7545
In view of the interest and concern of 4th Arm:y military authorities
who have the duty of protecting the vital installations at Los Alamos, N. M. ,
Sandia Base, N. M. in the El Paso Division, and the Camp Hood area in the San
Antonio Division, it is suggested that the Bureau may desire to arrange to have
Mr. WINCHELL interviewed concerning the source of his information that "flying
discs" emanate from Russia.
It would be appreciated if the Bureau can supply any infonna.tion that
can be transmitted to military authorities which would clarify this matter.
