Hon.J.Edgar Hoover Dept.F.B.I. Washington,D.C. Dear Sir: I have been hearing so much about the objects called Flying Saucers that I begin to speculate as to whether we are the only Nation or country to witness such a display. Of course it could be that those odd objects are pest filled Radqr controlled waiting to be punctured. We have been so accused by another Nation that no doubt they have devised some diabolical plan to test on us. I am not inclined to pass those over lightly,because I believe that those gadgets can be made and controlled to the extent of great numbers in groupings. Also, I believe it is very unwise to make public the locations of sightings as many folk are prone to worry, and a state of mind like this is exactly what our enemy is seeking. Any one wise enuf to perfect such would not only know their travel distance but also their location,therefore no talk or publications could benefit us in that. I hope that someone has had the integrity and foresight to learn where if in any other country these 'things' have been seen. INDEXED - 36 AUG 5 1952 291 Thanking you in advance for the courtesy of a reply,I remain 1 . 13 . 52 Let to Mr. Amfe Let to OSI . EHN: Ke Respectfully yours, Mrs. Fred Haufe
