SECURITY INFORMATION - CONFIDENTIAL 62-83894 Date: August 11, 1952 To: Director of Special Investigations The Inspector General Department of the Air Force The Pentagon Washington 25, D. C. From: John Edgar Hoover - Director Federal Bureau of Investigation Subject: FLYING SAUCERS SEEN NEAR THESSALON LAKE, ONTARIO, CANADA, JULY 27, 1952 MISCELLANEOUS - INFORMATION CONCERNING Dr. R. E. McIndoo, 820 West Walnut Street, Kokomo, Indiana, on July 30, 1952, advised that on July 27, 1952, at approximately 10:00 A. M. while fishing in the back waters of Thessalon Lake, Ontario, Canada, he noticed a formation of bombing planes, sixteen to twenty in number, in two groups flying south at a height estimated by him to be four or five miles. Dr. McIndoo stated that the planes went over the lake and suddenly dropped objects, at first thought by him to be parachutes. He continued that these objects fell straight for a short time, then suddenly spurted vapor and at a high rate of speed flew off in a southwesterly direction. Dr. McIndoo was unable to identify the nationality of the planes, but stated that they had twin trails of bluish smoke. He further stated that the objects which had been dropped from the planes had single trails of bluish smoke. Telecom Ladd Michols Belmont Clegg Glavin Barbo Roam Tracy Laughlin Mahr Tele. En.
