Chosica Power Plant (Peru) — July 25, 1965
Mr. Alva was awakened night by a strange sound and saw an object on the ground emitting green light flashes. He woke up other em- ployees, who had time to note that the object was about 3 m in diameter, had small windows in its upper part, and a revolving telescopic appendage. The in- vestigating commission found dark, triangular traces on the ground. (FSR 67, 6)
