FBI agents in the Newark Division interviewed witnesses to a flying disc sighting at Hackensack, New Jersey on August 3, 1947. Separately, the Detroit office reported that Raymond Edward Lane, a Dow Chemical Company employee, brought fused sand material to the Dow Physics Laboratory on July 10, 1947, after he and his wife observed a ball of white about the size of a bushel basket burning a foot off the ground in a Dow field near Midland, Michigan. The material was found to contain ordinary sand giving off ammonia gas, a small silver nugget, and a grayish substance described as radio active at an extremely low level.
