c/o Federal Beaura of Investigation The War Dept Washington D.C. ## Gentlemen: Since reading & hearing over Radio about the "flying saucers," I am compelled to Write to you - I am a strong believer in our almight God & Christ our Lord. I have the faith Daniel had. I feel that these Saucers are films from a secret Camera operated by something like T.V. I do believe, They are operating through the Comuniest Party right here in the, or our Unitid States, by radar Evey Group of Saucers has a picture, the best picture are kept for bombing purposes. Why "we see them just once & a while; They don't want the U.S. to catch on. To my opinion they have a way of causing them to be invisible. They can Lower them or send them high; When high they are invisible; It could be from an enemy plaine, or from a tall building in the United States. It could be the Camera is carried, in to cities and operated from tall buildings the ones that some one seen with a tail of fire is the picture that is Kept; So lets be on the look out for the next one and follow their path. Please Keep my Name confidently. /s/ Mrs. Ora A. Tygrett When they were over Washington D.C. it could a been from the Tallest building there. You might Start from the first place they were ever seen - trace back you might find the secret place. And pray with out sceasing "And have faith" Our good Bood - says do not let our secrets be known, when praying & trusting in God pray secretly into him.
