Documents / Official release
This Federal Bureau of Investigation file section, 62-HQ-83894 Section 6 (serials 246 to 301), collects FBI memoranda and correspondence from 1950 to 1952 on flying saucers. It covers green fireballs and discs seen near sensitive installations in New Mexico, Dr. Lincoln LaPaz's analysis, and the Air Force's Land-Air study known as Project Twinkle. It also holds an OSI summary, a USAF directive on reporting unconventional aircraft, a dissolving object reported by Philadelphia police, and letters from members of the public.

Date: May 7, 1952 CONFIDENTIAL Declassified To: Director of Special Investigations The Inspector General Department of the Air Force The Pentagon Washington 25, D. C. 2016 8/31/77 HP From: John Edgar Hoover, Director Federal Bureau of Investigation Subject: FRED J. EEKHOUT On May 5, 1952, Fred J. Eekhout called at this Bureau and advised that he is General Manager of Mouton and Company, Printers, 5 Herderstraat, The Hague, Netherlands. He resides at 49 Stadhouderslaan, The Hague. He is residing at the Victoria Hotel, New York City, until May 16, 1952, when he will return to Europe. Mr. Eekhout advised that he has a considerable interest in electronics and has been very much interested in reports circulated during the past year or two concerning the existence of flying saucers. He feels that there have been enough uncontradicted reports concerning such devices to indicate that they may exist in fact. He is also of the opinion that if they do exist they can be produced only by the United States or Russia or perhaps by the Republic of Argentina. Mr. Eekhout indicated that he has given extensive thought to the manner in which these devices could be operated. He has concluded that since the disk shape is not suitable for conventional aircraft it would be used only because it would provide the greatest possible lifting surface. It is his opinion, therefore, that one of these devices could be operated only by reducing the air pressure above it which would cause it to rise in the air. He concedes that conventional machinery to cause such a reduction of pressure would be so bulky that its weight would prevent the device from leaving the ground. He concludes, therefore, VHB:rdm 62-83894-473 INDEXED - 65 MAY 10 1952 MAILED 16 MAY 8 1952 OOMM - FBI
