## CONFIDENTIAL the top quarter which was flat, pot-shaped. The witness states that the object definitely did not have the curved trajectory of a wingless missile. Shartly after crossing his path, the blue flame sputtered and turned immediately earthward. The flame then died altogether but nothing was seen hitting the ground. Witness states that the flame was not of the long trailing type, but rather gave the impression that you were looking down a long exhaust stack at a short but concentrated mass of blue flame and further stated that his connections with RAF pilots in England during the war leads him now to believe this object looked the same as the "Buzz Bombs" chased by t ose RAF pilots at night. Arthur Porter, purser on this flight 9 January 48, also saw the object, the flame only, but can give no further evidence for its identification. Mr. DuBose stated on April 29 that seventy-five cattle had died of an unknown disease on the farm of a Mr. Gordy at Newnan, Georgia, and expressed concern over a possible connection between the unidentified object he reported and this unusual fatality among healthy cattle. However, the Atlanta Office of the Animal Industry Division, U.S. Department of Agriculture, advises that this "unknown" disease has persisted for over a year and other cases repeated elsewhere in the country for some time back. There apparently remains no basis for connection between the object Mr. DuBose reports and the death of seventy-five cattle at Newnan, Georgia.
