What was reported
A December 18, 1952 CIA memorandum relays a report from a CIA messenger who spoke with R.V. Jones (a senior British defense scientist) about a standing British flying-saucer committee. It states that roughly 10-12 days earlier, a 'Yorkshire incident' occurred at an RAF airfield: a 'perfect flying saucer' was seen by senior RAF officials and pilots during some kind of demonstration event, generating public press coverage that concerned Jones. A second page discusses US concerns that UFO reports could overload emergency communications or be exploited to induce mass hysteria, to be addressed via the Federal Civil Defense Administration.
