Tacoma, Washington

On August 25, 1947, Lt. Col. Donald L. Springer of Headquarters Fourth Air Force, A-2 Intelligence, Hamilton Field, forwarded to the FBI SAC in San Francisco a letter from F. M. Johnson, a prospector who wrote from Portland, Oregon on August 20, 1947, reporting that he had observed flying discs in the Ft. Adams district on June 24, 1947, the same date as the Kenneth Arnold sighting. Johnson described the objects as round, about 30 feet in diameter, tapering to a point at the head end, with a bright top surface, no engine noise, and a tail object shifting side to side like a big magnet.
