FBI headquarters file 62-HQ-83894, Section 5, contains 1949 investigative records on flying saucers, including a letter Walter Winchell received from Peter Camerlon Jones of Los Angeles, who claimed to have seen a large silver object shaped like a child's top in the mountains near Los Angeles in August 1947. D. M. Ladd directed the Los Angeles field office to discreetly check Jones's background and interview him, but efforts to locate Jones were negative. The FBI wrote to Ernest Cuneo on July 21, 1949, suggesting the original letter may have been a prank.
Large silver metal object, greenish in color, shaped like a child's top, approximately the size of a County Fair balloon, with two windows, portions of metal appearing transparent, resembling a pressure chamber; silent propulsion; knocked observer to the ground on departure (August 1947, mountains near Los Angeles)
