# Office Memorandum • UNITED STATES GOVERNMENT TO : MR. LADD FROM : A. H. BELMONT DATE: October 19, 1950 SUBJECT: FLYING SAUCERS CAEF The matter of flying saucers was discussed by Special Agent Edward S. Sanders with Major General Joseph F. Carroll of OSI on October 16, 1950, at which time General Carroll advised that insofar as he has been able to determine the Air Force is not working on any type of "flying saucer" or "flying disk". General Carroll stated that the Air Force is working on high altitude rockets and jet aircraft. He stated these experiments may account for some of the reports concerning flying saucers but that the Air Force is not apparently working on anything which is the cause of the many flying saucers reports. He stated that the Air Force program for investigating reports concerning flying saucers, etc., has been reinstituted at Wright Field and that any pertinent information of interest coming to his attention will be furnished to the Bureau. RECOMMENDATION: The foregoing is for your information. MRK ESS:i1w محمد . RECORDED - 38 OCT 1950 43515
