# The Lakenheath Radar Night [View on uap.fun]() CASE FILE 014 · 1956 Published: September 17, 2026 In August 1956 radar at RAF Bentwaters clocked a return at 4,000 miles an hour. At Lakenheath a target stopped, started and turned at right angles, and the Americans called for a fighter. By their teletype the Venom locked on, and then the target swung in behind it. The RAF crew, found forty years on, remembered a faint blip and nothing else. The record that could settle it is missing. ![Illustration of a back-facing 1950s radar controller at a circular green scope, looking through windows toward a rural night airfield, a distant fighter silhouette, and unresolved points of light.]() Not a real photo. ## AT A GLANCE - **DATE:** August 13–14, 1956 - **LOCATION:** RAF Bentwaters and RAF Lakenheath, Suffolk, England - **REPORT TYPE:** Military encounter - **RESOLUTION:** [Disputed explanation]() - **RECORD STATUS:** Unresolved; Air Force weather finding disputed ## The story ### “Real and not figments of the imagination” Three days after the night in question, the intelligence officer of the U.S. Air Force’s 3910th Air Base Group at RAF Lakenheath, Capt. Paula Stimson, sent a long classified teletype to Air Defense Command in Colorado and to the technical intelligence center in Ohio that housed Project Blue Book. It ended with a judgment. “My analysis of the sightings is that they were real and not figments of the imagination,” she wrote. “The fact that three radar sets picked up the targets simultaneously is certainly conclusive that a target or object was in the air.” It had been a tense summer at the base—seventeen days earlier a B-47 had crashed into Lakenheath’s nuclear weapons store—and the radar room where much of this happened had been open only a few weeks. The man in charge of it that night, Tech. Sgt. Forrest Perkins, remembered how it began: a telephone call from another base asking whether Lakenheath had any targets on its scopes doing four thousand miles an hour.

Then a cluster of twelve to fifteen blips came drifting out of the southwest, spread across six or seven miles, and appeared to merge into one enormous echo, which stopped, moved, and stopped again before leaving the screen. A third fast target went east to west. The operators said the blips looked like normal aircraft returns, and a check found nothing wrong with the set. Lakenheath saw none of these early tracks, and the operators’ arithmetic does not always agree with the ranges and sweep times they reported.

Bentwaters’ control tower chief, Lawrence Wright, watched an amber, star-like light low in the southeast for about an hour. Mars was there, rising, and that month it was making what Blue Book’s own record card noted was its “closest approach to the Earth in 32 years.” Two lieutenants, Charles Metz and Andrew Rowe, were sent up in a T-33 jet trainer to look for the radar targets and spent forty-five minutes finding nothing but a bright star and one other thing, which the intelligence report records in a sentence that would mean more to a later generation: “Lt. Rowe also stated that a flashing beacon was flashing through a low haze along the east coast of England from the vicinity of the village of Orford.” Twenty-four years on, the same lighthouse would be the skeptics’ answer to the lights that airmen from the same base chased through Rendlesham Forest. The RAF’s night was going no better. A Venom fighter scrambled from Waterbeach that evening lost both wingtip fuel tanks over the countryside near Cambridge; they were found in a cornfield, and the crew was interrogated. The squadron’s commanding officer, Anthony Davis, wrote years later that he had been airborne himself and “found myself chasing a star.” Sources: [Air Intelligence Information Report IR-1-56]() · [Project 10073 record card: Bentwaters–Lakenheath]() · [Astronomical comments on the Lakenheath case]() · [The Fate of British MoD Records]() · [History, documents, and witness archive for the Lakenheath case]() ### The white light over the field At 10:55 p.m. Bentwaters had a new target coming in from the sea, thirty miles east, at what the teletype gives as 2,000 to 4,000 miles an hour. It vanished from the scope two miles east of the station, reappeared three miles west, and ran off the edge. A ground radar is blind directly overhead, so the gap alone means little. What made the track hard to forget is that the report pairs it with two sets of eyes. Men in the tower said a bright light had streaked over the field from east to west at terrific speed, at about four thousand feet. And the pilot of a C-47 transport passing over the base at that height said a bright light had streaked underneath him.

Ten minutes after midnight, by the teletype, they had an echo twenty to twenty-five miles southwest that was not moving and should therefore have been invisible. A second radar of a different type confirmed it. Then it moved: north-northeast at 400 to 600 miles an hour, with no build-up of speed, to a dead stop; then off again in another direction. “Object would stop and start with amazing rapidity,” the teletype says, and made right-angle turns at 600 to 800 miles an hour. Four intelligence specialists from the 307th Bomb Wing went outside and reported small white lights doing the same. Stimson thought the “rapid acceleration and abrupt stops” seen both ways “certainly lend credulance to the report.” Perkins remembered conferencing in the 7th Air Division, Third Air Force, and his base commander on one telephone line. Somebody asked the RAF for a fighter. Sources: [Teletype BOI-485]() · [Letter to the University of Colorado UFO project]() · [The Lakenheath Radar/Visual UFO Case]() ### A Venom enters the story In the American version, a de Havilland Venom night fighter arrives from Waterbeach and is steered onto a target six miles east of Lakenheath. The pilot sees a bright white light and says he will investigate; it disappears. He is sent after another return, and the teletype has him advising that the “target was on radar and he was ‘locking on.’” Then the scope shows something the controllers had never seen: “The target began a tail chase of the friendly fighter.” The pilot “was unable to ‘shake’ the target off his tail and requested assistance.” Before he went home low on fuel he offered an opinion: “Clearest target I have ever seen on radar!” A second Venom took off and turned back with “malfunctions.” That is the record made at the time. The lines everyone remembers come from a letter Perkins wrote to the University of Colorado’s UFO project twelve years later. In it the pilot radios, “Roger Lakenheath I’ve got my guns locked on him,” then, “Where did he go? Do you still have him?” He tells the pilot coming up to relieve him, “I saw something but I’ll be damned if I know what it was,” and, “It’s the damndest thing I’ve ever seen.” He sounded, Perkins wrote, “worried, excited and also pretty scared.” Sources: [Teletype BOI-485]() · [Letter to the University of Colorado UFO project]() · [Case 2: “Greenwich,” summer 1956]() ### The aircrew remembered a different interception Nobody asked the pilots for forty years. In the mid-1990s a BBC researcher and the historians David Clarke and Andy Roberts traced the two crews of No. 23 Squadron, and they had kept their logbooks. Navigator John Brady’s shows Venom NF3 ‘E’ taking off at 2:00 a.m. on August 14 for fifty-five minutes, with a note unusual enough that he wrote it down: “scrambled and controlled by the USAF.” He and his pilot, David Chambers, made several passes at a spot the Americans kept steering them to. “It was stationary,” Brady said; all he ever got on his set was “this little, faint paint.” Chambers looked out each time and saw nothing at all. Brady’s guess was “probably a met balloon.” He never called “Judy,” the RAF code for a navigator taking over an interception. Shown the gun-lock dialogue, he said, “RUBBISH!” and, of its phrasing, “That’s American language.” Chambers said of the published story, “I think it’s nonsense.” The second crew’s logbooks fit the teletype rather better. Navigator Ivan Logan recorded a 2:40 scramble and recalled weak contacts of his own, and pilot Ian Fraser-Ker’s entry explains the “malfunctions”: “FAB scramble had Hydraulic failure.” He “saw nothing!” It was the last flight of his RAF career. Brady and Logan were filmed at Lakenheath for a 1996 documentary; Brady was paid forty pounds in expenses and thought the result “cringe making.” Sources: [Interview with RAF navigator John Brady]() · [Interview with RAF pilot David Chambers]() · [Letter from RAF navigator Ivan Logan]() · [Recollections of RAF pilot Ian Fraser-Ker]() · [History, documents, and witness archive for the Lakenheath case]() ### A third version from the RAF’s own radar There is another British account, and it agrees with nobody. In 1978 a retired officer signing himself “R.A.F. Fighter Controller” wrote to Flying Saucer Review; he was Flight Lt. Freddie Wimbledon, chief controller that night at the RAF’s radar station at Neatishead. The Venom, he insisted, “was never at any time under the control of Lakenheath.” His own team had scrambled it and talked it in. The pilot called “Contact,” then “Judy”—the navigator had it—and then “the object appeared behind our fighter,” followed by “Lost contact, more help.” Afterward “a Senior Officer from Air Ministry came down and interrogated us,” and Wimbledon’s logbook, he told Clarke, was taken away. Brady, whose logbook says the Americans controlled him, could not credit it: “I can’t believe that!” Researcher Martin Shough thinks the two men may simply be describing different interceptions, and that the one Wimbledon saw is otherwise lost; one more retired navigator has since recalled hearing over the radio that night, “I think they are now on our tail!” It cannot be checked. Of all the Neatishead sector’s operations record books in the national archives, the one for August 1956 is missing. Davis, who went from commanding 23 Squadron to running the Ministry of Defence’s UFO desk, wrote in 1972 that UFO reports from before 1962 had been destroyed. And a later head of that desk, Ralph Noyes, said that around 1970 he was shown clips in a small ministry cinema of what he understood to be gun-camera film of UFOs. Asked in 1994, the ministry could find no trace of them. Sources: [Letter from an “R.A.F. Fighter Controller (Rtd.)”]() · [Interview with RAF navigator John Brady]() · [The missing interception]() · [The Fate of British MoD Records]() · [UFOs over RAF Lakenheath]() ### Blue Book closes the card; Colorado opens it again Blue Book’s consultant astronomer, J. Allen Hynek, called it “one of the more unusual reports,” thought meteors “highly unlikely” as the cause, and warned that “the Lakenheath report could constitute a source of embarrassment to the Air Force.” The project’s chief, Capt. George Gregory, was unmoved. He found it suspicious that two stations had both arrived at “exactly 4000 m.p.h.,” suspected “some contact (I do not wish to use the word ‘collusion’)” between them, and ruled that “our original analyses of anomalous propagation and astronomical is more or less correct.” The record card says “Anam. Propagation” and notes that the observations “cannot be considered concurrent.” There it sat until Perkins’s letter landed in Boulder in 1968 and the Colorado project’s radar specialist, Gordon Thayer, pulled the file. His verdict, in the government-funded study remembered for dismissing UFOs, reads: “This is the most puzzling and unusual case in the radar-visual files. The apparently rational, intelligent behavior of the UFO suggests a mechanical device of unknown origin as the most probable explanation of this sighting.” The report’s case summary, which disguises the location as “Greenwich,” goes further: “the probability that at least one genuine UFO was involved appears to be fairly high.” Thayer later explained that by “genuine UFO” he meant only something material, flying, and unidentified. Physicist James McDonald made the case a centerpiece of his attack on the study’s negative conclusions, and in 1971 the American Institute of Aeronautics and Astronautics published Thayer’s fuller analysis as a specimen of the kind of report that deserved scientific attention.

[Image source]() [Public domain — U.S. federal government work]() ### Four ordinary explanations, none for the whole night Mars accounts well for the amber light. Ground observers said shooting stars were unusually numerous, and Philip Klass leaned on the Perseids for the streaks; the British Astronomical Association’s records put that night two days past the shower’s peak, at a modest twenty an hour. Balloons suit the slow cluster at Bentwaters and the faint, stationary paint that Brady met at two in the morning. For the radar, Klass proposed that Lakenheath’s moving-target indicator was faulty and throwing up ghosts, noted that a long-range set turning four times a minute could not have drawn a fighter and a pursuer circling each other, and pointed out that the Lakenheath targets appeared two hours after the Bentwaters ones and may have had nothing to do with them. August is the high season for false radar echoes. Against that, the weather balloon sent up from Hemsby at two that morning found nothing remarkable in the atmosphere, five stations reported a cloudless sky, and Thayer and McDonald argued that radars of different types on different frequencies do not usually hallucinate the same target. The Air Ministry’s own technical intelligence branch, in a briefing the following spring, had a cooler memory of it: a radar object at “two and four thousand knots,” but “no visual contact was made with this object by the Venom… other radars failed to pick it up.” Sources: [Astronomical comments on the Lakenheath case]() · [Interview with RAF navigator John Brady]() · [History, documents, and witness archive for the Lakenheath case]() · [Meteorological analysis for the night of August 13–14, 1956]() · [The Lakenheath Radar/Visual UFO Case]() · [Air Ministry DDI (Tech) briefing on unidentified radar objects, AIR 2/18564]() ### What remains on the green scope Lakenheath survives as three stories that cannot all be true and may all be partly so: an American radar room watching something stop, start, and swing in behind a jet; a British aircrew nudging at a motionless speck and going home unimpressed; a British controller hearing his pilot call “Judy” on a target that then got behind him. Each has paper behind it. The one document that might settle which fighter chased what, the Neatishead record for that month, is gone. Were there two interceptions or one? What did a captain of intelligence see in the reports that made her write “real” to three commands? And what was the C-47 pilot looking at when a light went under his wing at four thousand feet?

Fighter Controller (Rtd.)”]() · [The missing interception]() ## The evidence ### The contemporary documentary spine The core is two American documents, the Lakenheath teletype of August 16 and the Bentwaters intelligence report of August 31, plus Blue Book’s correspondence and record card and a 1957 Air Ministry briefing. They establish that controllers at two bases reported unusual returns, that visual reports went up the chain, that aircraft searched, and that both air forces took notice. No radar film, photograph, cockpit recording, or signed RAF aircrew statement from 1956 survives.

Perkins could not remember the month, named the calling station as Sculthorpe rather than Bentwaters, and put the C-47 at five thousand feet where the teletype has four. The teletype itself says the ground observers had moonlight, though the first-quarter moon had set before the Lakenheath phase began. It dates Lakenheath’s radar observations from ten past midnight, later than most retellings. The aircrews spoke forty years on, with logbooks to anchor times but not altitudes: Brady recalled seven thousand feet, Chambers three or four thousand, Logan two or three.

Redundancy counts only when contacts can be matched in time and place, and here no common recording exists: Blue Book judged the observations not concurrent, Lakenheath never saw the first Bentwaters tracks, and the British briefing says other radars failed to pick the object up.

The crew most likely to have flown the sortie accept a faint contact and reject everything else; a British controller describes a chase but denies the Americans had any part in it. The available record supports an interception and a radar search. It cannot say whether the chase happened, or to whom.

Fighter Controller (Rtd.)”]() · [The missing interception]() ### Classification This file is classified as an unresolved military radar-visual episode with a disputed official finding of anomalous propagation. The conventional case is cumulative: Mars, meteors, balloons, a possibly faulty filter, and atmospheric echoes each fit part of the night, and the Air Force’s own scientific consultant and the Colorado study’s radar analyst both declined to accept that they fit all of it.
