## Dear Mr. Hoover: The motive of this letter is a sincere effort to help avoid useless waste of life, time and money. It is written with full respect to your pressing work, and to the ability of this country's scientific experts. Although your responsibilities may not be directly connected with the intended text of this letter, I sincerely hope that you will consider the possibilities, and forward the suggestions to the proper authorities concerned. For the past five years the general public has read, and ballyhoed newspaper articles related to the "Flying Saucers", and following the same trend of thought have ignored recent reports made by persons of undisputed experience and intelligence. The possibilities of this earth being visited by ships from outer space have been lightly suggested by some, while others believe the "objects" belong to some nation on this earth. Granted that some such objects do even belong to this country, it is obvious that we, nor any other nation possess and fail to use, in time of war, such useful means as have been reported by the balloon experts connected with General Mills, Inc. I am sure that these suggestions will bear scientific investigation and that they are entirely probable. Similar to Columbus and the egg - they may not have been given due consideration. These "objects" of undetermined origin" (not to be confused with our controlled weather balloons, etc.) are in all probability operated by the absorption, compression, and controlled emission of the sun's energy (basically electricity). As such, they probably carry a potential charge which is past our imagination. An earthly object approaching too close to the O.U.O. would have the same effect as grounding a high tension wire, with the total destruction of both objects as a likely result. Assuming that some of these objects are from outer space, we would certainly benefit considerably by establishing contact with them, where as, if such a nation as Russia should acquire this knowledge before us we would certainly suffer as a result RECORDED - 46
