The UFO Library: Military encounter
Little Rissington UFO Incident
RAF Gloster Meteor VII encounters three saucer-shaped objects at 35,000 feet with independent radar confirmation from GCHQ and civilian radar station.
The Encounter
On the afternoon of 21 October 1952, during a routine high-level navigation exercise, Flight Lieutenant M.J.E. Swiney (instructor) and Lieutenant D. Crofts, R.N. (student), were flying a Gloster Meteor VII at approximately 35,000 feet over Gloucestershire when they observed three highly unusual objects. The aircraft was on a standard training sortie from RAF Little Rissington, a fighter pilot training facility near Cheltenham.
The three craft appeared to be disc or saucer-shaped and were traveling at high speed in formation. The encounter occurred during daylight hours, giving the trained military pilots a clear visual sighting. Both men were experienced aviators—Swiney held the rank of Flight Lieutenant and Crofts was a Royal Navy pilot serving as a student—lending credibility to their observations.
Corroboration and Evidence
What distinguishes this incident from countless unconfirmed sightings is the independent radar corroboration. During the same time period, the air traffic control center at Gloucester (ATCC Gloucester) independently plotted the movements of unidentified objects on their radar systems. Critically, these radar plots aligned with the visual sighting from the Meteor, establishing a rare radar-visual correlation that eliminates conventional explanations.
The British intelligence organization GCHQ intercepted radio communications between the Meteor aircrew and RAF Little Rissington as the encounter was unfolding, creating an additional documentary record of the incident. The presence of GCHQ monitoring and recording indicates the sighting was taken seriously enough to warrant signal intelligence protocols during the investigation phase.
Official Response
Despite the credible witnesses, radar confirmation, and intelligence agency involvement, the Air Ministry quickly moved to discount the sighting. Officials publicly stated there was no possibility these objects were "extraterrestrial" in origin, though they offered no plausible explanation for what the radar and the trained pilots had observed. The incident was successfully suppressed from public knowledge at the time, unlike some other dramatic sightings from the 1952 wave that leaked to the press.
Historical Context
The Little Rissington incident occurred during the intense 1952 UFO wave, which saw unprecedented activity across the UK and NATO forces. The month of October 1952 alone generated hundreds of reports. This incident preceded the famous Operation Mainbrace sightings that same month and was part of a broader pattern of military and civilian observations that prompted official inquiries and considerable concern within defense establishments.
The incident remains one of the most credible early British military encounters, combining the testimony of high-ranking trained observers with independent electronic confirmation.
Witnesses
Flight Lieutenant M.J.E. Swiney (RAF instructor, Gloster Meteor VII pilot) — Experienced military aviator with aircraft rating; primary observer during the encounter.
Lieutenant D. Crofts, R.N. (Royal Navy, student pilot) — Naval officer serving as student pilot on the navigation exercise; co-observer and secondary witness.
