Senior RAF Officers Spot a Flying Saucer at a Yorkshire Air Show
Senior officers and pilots saw it at a display in Yorkshire. Newspaper stories followed, and the scientist handling the case grew concerned.

British officers and pilots saw a flying saucer during an air show in Yorkshire. The sighting made the newspapers and worried the scientist handling the case, but a memo does not explain what the object was.
A SECRET CIA Office of Scientific Intelligence Memorandum for the Record dated 18 December 1952, signed by Assistant Director H. Marshall Chadwell, reporting on British activity concerning 'Unidentified Flying Objects.' It relays an account from a recently arrived messenger from Britain who spoke with R. V. Jones, describing a British standing committee on flying saucers (formed about sixteen months earlier, now under Jones) that concluded the observations are not enemy aircraft and none have been over Britain. It notes a recent 'Yorkshire incident' in which a 'perfect flying saucer' was seen at an RAF field demonstration by high RAF officials and pilots, prompting public press coverage. A second page discusses potential dangers of UFO sightings (early-warning interference, mass hysteria, and emergency-communications overload) and plans to raise these with the FCDA, ICIS, and the Joint Communications and Electronics Committee.
About ten to twelve days before the memo, during a demonstration at an RAF field to which high RAF officials from London had been invited, a 'perfect flying saucer' was observed by the officials as well as by RAF pilots. So many people saw it that articles appeared in the public press.
Jones reminded the messenger of the Swedish incident, presumably referring to the 1946 events.
Reference to the Tremonton incident: a film taken by a Naval non-commissioned officer. Jones may write asking for a copy of the film or further information on the subject.
"The group has concluded that the observations are not enemy aircraft and that none have been over Britain."
Why it matters: Official British committee conclusion on the nature/origin of the sightings.

Why it matters: Firsthand-relayed account of a mass UFO sighting at an RAF field by senior officials and pilots.

"While there is no indication that these objects represent a direct threat to the national defense, there are certain potential dangers which are related to these sightings."
Why it matters: Official assessment framing UFOs as a procedural/defense-system danger rather than a direct threat.

"The possibility of mass hysteria which might be purposely induced by an enemy at a critical time by faked reports."
Why it matters: Articulates the Cold War concern that UFO reports could be weaponized for psychological/communications disruption.

Likely reason: A second person's name accompanying R. V. Jones appears withheld or unrecovered.
OCR is degraded with many garbled words but core content is recoverable. Document is a two-page CIA OSI memo released 2026 under the FY2024 NDAA; the manifest notes a more heavily redacted version is publicly available on CIA's website. Page 2 reads as a separate policy passage (potential dangers / agency referrals) appended to the Chadwell memo.
Senior RAF officers invited from London, along with pilots who were at the air show.
No. The memo describes the report but does not explain what the object was.
At an RAF airfield in Yorkshire, senior officers invited from London and pilots saw something described as a flying saucer during an air show. The sighting took place in Britain, in front of a crowd gathered to watch the display.
Many people saw the object, and newspapers ran stories about it. The report reached the scientist handling the case and worried him. What exactly did people see at the airfield, and why was the scientist also concerned about public opinion?
Britain had a committee that dealt with reports of flying saucers. It operated quietly until an incident in Yorkshire, about 10 to 12 days before information about it was passed to the Americans.
A U.S. memo from December 1952 says senior RAF officers from London were invited to an air show. Pilots were there, too. During the event, according to the memo, they saw “a perfect flying saucer.”
The memo uses that phrase to describe what the witnesses saw. It does not identify the object or include an explanation from the event’s organizers or the British committee.
Many people saw the object, and newspaper stories about it appeared in the press. R. V. Jones, the scientist handling the case, understood that the reports’ effect on public opinion was also his responsibility. He was concerned not only with what had appeared in the sky, but also with how people would interpret the sighting.
The memo recounts his concern but gives no details of what he said about the incident itself. It describes the event briefly, leaving readers with no account of the object beyond the words “a perfect flying saucer.”
The memo does not explain what was seen at the airfield or what caused the sighting. It says the British committee believed the sightings were not of enemy aircraft and thought there had been no such aircraft over Britain.
Many people at one airfield saw the same thing. But the memo does not reveal exactly what passed overhead.
