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. الدول Dickerson for 2040 Michols___ Belmont___ SECURITY INFORMATION - COMMUNITIAL Glevin EAB:mes RECORDED-86
