Thad W. Culmer II Post Office Box 99 Robinson, Illinois Mr. J. Edgar Hoover, Director Federal Bureau of Investigation Washington, District of Columbia Dear Mr. Hoover: Perhaps this is a little out of your line of endeavor, however, I feel that perhaps you or your organization might be able to give me some information concerning the following matter. From the first time it was written up in the press I have been keenly interested in strange celestial phenomena such as the flying disks popularly called "flying saucers." Now out of all the thousands of people who have reported sightings not all of them have had too much to drink, nor could they have been victims of optical illusions, retinal retention, or hallucinations. Some of the objects sighted could not have been jet craft, guided missiles, or rockets, neither could they all have been weather instruments. Unretouched and undoctored photographs have given evidence that someone must have seen something. It seems that both civil and military authorities are most willing to proclaim what the objects are not. I feel there is more to the matter than meets the eye. My decision to write you was based on the thought I would get straight answers. Do you have any ideas or data on this subject? What are your opinions? If not, where might I write for such information? Any kindness, consideration, or information which you can extend toward me concerning this matter will certainly be most sincerely appreciated. Very truly yours, N ? DEBLI DE INJEICE EBI RECEIED Jhn W. Coulue Thad W. Calmer II.
