# PASCOITES SPOT MYSTERY' OBJECT # 'Saucer Like Giant Pinwheel' A brilliant and high speed object that flashed through the sky over Pasco was reported by five persons living in the Navy Homes Project. Presence of the objects aroused much speculation as result of the final admission by the Army Air Force that such objects have been sighted on radar screens and have been chased by fast jet airplanes. The object reported over Pasco last night was described in almost identical detail by all persons who reported they had seen it. The time of the object's appearance also coincided. Mrs. Fern Jorgenson, 10-B Navy Homes, said the "saucer" was round and seemed ringed with flashing lights, mostly green. ALL INFORMATION CONTAINED HEREIN IS UNCLASSIFIED EXCEPT WHERE SHOWN OTHERWISE "Columbia Basin News" July 29, 1952 Pasco, Washington "It seemed to be traveling at terrific speed," she said. "I blinked my eyes once after I first saw it and it appeared to have gone miles during the fraction of a second my eyes were closed." Mrs. Jorgenson's husband also witnessed the strange sight. Three boys who were playing in a field back of the Navy Homes' registration office, also reported seeing the strange sight. "It was just like a giant pinwheel," said Timothy Hogland, 9-B Navy Homes. "It seemed to spin but it went so fast you hardly could follow it." Robert Greeno, 53-B Navy Homes, said: "It came out of the west and streaked across the sky. It disappeared in the east." Thomas Thompson, 10-D Navy Homes, had another comment. It was: "It couldn't have been an airplane with running lights. I've seen too many of them. This was round and it was ringed with lights. It traveled too fast for an airplane." The closest check possible last night disclosed that there were no scheduled flights of airplanes over this area at the time. Another party also said he saw the object but refused to be named in the matter. He is an experienced flyer and said it definitely was not an airplane. "I can only describe it by saying it was something out of this world. I never have seen the like of it before." SERIALIZED FILED JUL 30 1952 FBI - SEATTLE 100-18945-35
