The 415th Night Fighter Squadron, 27 November 1944: the case the Air Ministry called 'still something of a mystery'

On 13 March 1945 the British Air Ministry sent its written response to the Supreme Headquarters Allied Expeditionary Force in Paris. A US Army Air Forces night-fighter squadron operating over the Rhine had been reporting glowing orange spheres pacing its Bristol Beaufighters at night. The 415th Night Fighter Squadron’s intelligence section had compiled fourteen separate incidents. XII Tactical Air Command in southern France could not explain them. SHAEF had sent a SECRET classified message to the War Department in Washington on 2 January 1945, under Brig. Gen. Clayton L. Bissell, asking for an assessment. Washington produced none on the record. SHAEF turned to London.

The Air Ministry replied that RAF Bomber Command crews had been making similar reports. A small number of the alleged aircraft might have been Messerschmitt Me 262 jet fighters. Flak rockets were the “most likely” candidate for the remainder. And then it put the sentence in writing that the case has run on ever since: “the whole affair is still something of a mystery.” Five days later, on 18 March 1945, SHAEF forwarded the assessment up its own chain and closed the file with “no further, or more definite, information.”

That written admission, from an Air Ministry at the height of its wartime intelligence capacity, is the spine of the case. Eighty years on, no postwar interrogation of German aerospace and Luftwaffe personnel has produced an admission of a programme matching the reports, and no archival find has either. The Robertson Panel of January 1953, convened by the CIA, cited the foo fighter reports as part of its prehistory and proposed candidate natural-phenomenon explanations. It noted in writing that “if the term ‘flying saucers’ had been popular in 1943-1945, these objects would have been so labelled.” It did not produce an evidentiary identification.

What follows is the case the chain of inquiry made. The three layers below are kept separate.

The documented account

The 415th Night Fighter Squadron of the United States Army Air Forces was activated on 10 February 1943 and worked its way through North Africa, Tunisia, Sicily, Italy, Corsica, and southern France. By the autumn of 1944 it was operating from Advanced Landing Ground A-96 at Ochey and the airfield at Dijon-Longvic, in eastern France, flying the British-made Bristol Beaufighter until the Northrop P-61 Black Widow arrived in the spring of 1945. The commanding officer at the relevant time was Capt. Harold Augsperger; the intelligence officer was Lt. Frederic “Fritz” Ringwald.

On the evening of 27 November 1944 a Beaufighter of the 415th was on patrol over the Rhine, north of Strasbourg. The crew comprised Lt. Edward Schlueter as pilot and Lt. Donald J. Meiers as radar operator. Ringwald flew with them as an observer. The aircraft picked up eight to ten bright orange lights off the left wing, moving at high speed and apparently in formation. Schlueter turned toward them and they disappeared. They reappeared at a greater distance. The display continued for several minutes. Neither the Beaufighter’s airborne intercept radar nor ground control reported any return at the relevant positions.

Meiers, in the debriefing that followed, reached for a name. He was from Chicago and read the Chicago Tribune’s syndicated comic strip Smokey Stover by Bill Holman, in print daily from 10 March 1935, whose protagonist was billed as “the foolish foo fighter” and whose catchphrase was “where there’s foo, there’s fire.” Holman’s “foo” was a nonsense word he attributed variously to the French feu and to a jade Chinese figurine. Meiers, with an expletive that Capt. Augsperger sanitised for the squadron record, declared the objects to be “foo fighters.” The name went onto the form.

The 27 November date carries a second squadron incident. Later the same evening, Lt. Henry Giblin and Lt. Walter Cleary reported being followed in the vicinity of Speyer by an “enormous burning light” that flew above their aircraft at about 200 to 250 miles per hour. In the weeks that followed, other 415th aircrew added accounts. Lt. Wallace Gould described lights pacing his wingtip and climbing out of sight, with no visible structure on the spheres even at close range. Lt. Samuel A. Krasney described a wingless cigar-shaped object glowing red.

The press took the story on 31 December 1944. AP correspondent Robert C. Wilson, weathered in at the 415th’s base, spent New Year’s Eve with the squadron and filed a wire dispatch on 1 January. The New York Times and the St. Louis Post-Dispatch ran it on 2 January. Meiers was quoted distinguishing three classes of object: red balls of fire flying along off the wingtips; a vertical row of three balls in front of the aircraft; and a group of about fifteen at distance. Time magazine, 15 January 1945, called the objects “the most puzzling secret weapon” and floated St. Elmo’s fire and radio control; Newsweek the same week suggested an anti-radar device.

The intelligence chain ran in parallel with the press. Ringwald compiled fourteen sightings logged between mid-December 1944 and late January 1945. The report was forwarded from the 415th to the 64th Fighter Wing and on to XII Tactical Air Command, which could offer no explanation. The inquiry went up to SHAEF, then by the 2 January 1945 SECRET cable to the War Department, and finally to the British Air Ministry in London.

The Air Ministry replied on 13 March 1945: RAF Bomber Command crews were making similar reports; a small number of the objects might be Me 262s; flak rockets were “most likely” for the rest; the whole affair was still something of a mystery. SHAEF closed its file on 18 March 1945. The aircrew did not accept the dismissal. Stars and Stripes, on 19 February 1945, carried the line attributed to the pilots: “If we’re starting to see things now, we’d better quit and go home.”

Across the Pacific, B-29 crews of the Twentieth Air Force, flying out of bases in the Marianas, generated their own reports of “balls of fire” pacing aircraft at high altitude during the strategic bombing campaign against Japan. Period and postwar treatments commonly cite over 300 ball-of-fire sightings by 140 B-29 crew members in the final year of the war, a figure that rests on modern compilation rather than a published primary table. The spheres were described as sometimes hanging in the sky and sometimes following the aircraft; gunners reportedly engaged them in a small number of cases. The April 1945 raids on Tokyo and Kawasaki are among the more frequently cited Pacific dates.

In the autumn of 1945 the US Air Force in Europe’s intelligence section questioned thirteen German scientists, engineers, and former senior Luftwaffe officers about any programme matching the reports. None claimed knowledge of one. From January 1948 the first US Air Force study of unidentified flying objects, Project Sign at Wright-Patterson AFB, treated the foo fighter reports as the prehistory of the postwar UFO file. The project’s “Estimate of the Situation,” reportedly arguing for an extraterrestrial hypothesis, was rejected by Air Force Chief of Staff Gen. Hoyt Vandenberg; the original has never been recovered. Project Grudge took over in 1949 and Project Blue Book from 1952.

The Robertson Panel, a CIA-convened group of five scientists chaired by the physicist H. P. Robertson, met at the Pentagon from 14 to 17 January 1953 to review the postwar UFO problem. It treated the foo fighters as part of the prehistory, observed that the behaviour of the objects had not been threatening, and proposed candidate natural-phenomenon explanations: St. Elmo’s fire, electromagnetic phenomena, and reflections of light from ice crystals. The panel did not produce, and was not asked to produce, an evidentiary identification of the phenomenon.

The evidence

The record runs on testimonial and official-record evidence. There is no radar return on the foo fighters themselves: the airborne intercept radars on the Beaufighters registered nothing where the orange lights were, and Ground Control Intercept reported the same.

The 415th NFS squadron debriefs and mission reports. From late November 1944 through January 1945 the squadron’s intelligence section logged sortie summaries describing variously a light four to five times larger than a star near Erstein, an orange glow consistent with a possible jet, and amber lights of approximately one foot in apparent diameter following a Beaufighter. Each carries the same notation: negative airborne intercept radar and negative Ground Control Intercept contact. Ringwald’s fourteen-incident compilation, forwarded to XII Tactical Air Command, is the central Allied documentary record.

The named aircrew. The witness chain is signed. Schlueter, Meiers, Ringwald, Gould, Krasney, Giblin, Cleary, and others, debriefing through their own squadron intelligence officer rather than to a reporter.

The period press. Wilson’s AP dispatch of 1 January 1945 brought the term “foo fighters” to the national press for the first time. Time and Newsweek, both 15 January 1945, called the phenomenon “the most puzzling secret weapon” and floated St. Elmo’s fire and the anti-radar device. Stars and Stripes on 19 February 1945 carried the pilots’ “we’d better quit and go home.” The press of the period is the period treating the case as a real intelligence question.

The classified chain. The SHAEF SECRET cable to the War Department of 2 January 1945, under Bissell. The XII Tactical Air Command formal report of 16 January 1945. The Air Ministry written response of 13 March 1945, with its “still something of a mystery” formula and its Me 262 and flak-rocket candidates. The SHAEF close-out of 18 March 1945 with “no further, or more definite, information.” This is the document run that the case rests on.

The postwar interrogations. The autumn 1945 questioning of thirteen named German scientists, engineers, and senior Luftwaffe officers by US Air Force in Europe intelligence. No admission of a matching programme was produced. Subsequent archival work, including the Combined Intelligence Objectives Subcommittee files on German aeronautical research, has not produced one either.

The Project Sign file. January 1948 to April 1949, Wright-Patterson AFB, treating the foo fighter reports as the prehistory of the UFO problem. The rejected “Estimate of the Situation” is reported across the postwar literature; the original is not extant. Project Grudge from 1949 and Project Blue Book from 1952 inherited the foo fighter material as historical context rather than as live cases.

The Robertson Panel report. 14 to 17 January 1953, chaired by Robertson. This sits at the hinge between layer two and layer three: the panel’s statement that its St. Elmo’s fire and ice-crystal natural-phenomenon candidates were candidates is a documented official statement; the candidates themselves remain unconfirmed hypotheses about the 1944-45 phenomenon. The panel made no evidentiary identification.

The Pacific theatre B-29 reports. Documented in unit histories and in postwar accounts of the strategic bombing campaign; consolidated in Graeme Rendall, UFOs Before Roswell (2021), the standard modern catalogue drawing on RAF squadron war diaries, USAAF mission logs, and declassified intelligence files. The “over 300 sightings, 140 crews” figure is from this compilation.

Hypotheses and open questions

Seven hypotheses sit on the open record. Each is labelled and attributed. None is asserted as fact.

A. A German secret weapon. The wartime working hypothesis of every Allied chain of inquiry, and the position the Air Ministry’s response was reaching for when it offered the Me 262 and flak rockets. Constraints: the Me 262 was a recognised jet with a known signature and was being engaged by Allied fighters; flak rockets do not pace aircraft for minutes at consistent distances; the autumn 1945 interrogations produced no admission of a programme, and no archival find in eighty years has produced one.

B. Natural electrical or optical phenomena. The Robertson Panel’s January 1953 candidate menu: St. Elmo’s fire, electromagnetic effects, ice-crystal reflections. Time magazine raised St. Elmo’s fire in January 1945. The US Navy’s Bureau of Medicine investigation into night-flight visual disorientation, Project X-148-AV-4-3, began in April 1945. Constraints: aircrew rejected the dismissal in the period record (“if we’re starting to see things now”); the objects were reported by multiple crew members concurrently and tracked their aircraft over distances and manoeuvres that St. Elmo’s fire, an electrical discharge on the airframe itself, does not produce.

C. Ball lightning. A recognised but poorly characterised atmospheric phenomenon, typically weather-correlated. Constraints: ball lightning is not known to pace aircraft over minutes at consistent distances; the foo fighter reports were not weather-correlated in the squadron record.

D. An anti-radar device. Floated by Newsweek on 15 January 1945 and recurring in later speculation. The thesis is that the objects were intended to interfere with Allied airborne intercept radar. Constraints: the airborne intercept radars consistently registered nothing on the spheres themselves. A device intended to spoof radar that does not appear on radar is a strange design.

E. Renato Vesco’s Feuerball thesis. The Italian aerospace engineer Renato Vesco, in Intercept UFO (1968; English as Man-Made UFOs: 50 Years of Suppression, 1994), proposed a specific German weapon: a ground-launched guided flak mine supposedly developed at the SS-controlled aeronautical institute at Wiener Neustadt, gas-jet propelled, with klystron tubes and collision-avoidance radar. Constraints: the Vesco thesis is unsupported by any archival find. It is reported here as documented later speculation, not as evidence.

F. Pilot fatigue and combat hallucination. Behind the Bureau of Medicine 1945 investigation. Constraints: the dismissal was rejected at the time by experienced 415th aircrew and by experienced B-29 crews, and does not account for the multi-crew, multi-sortie pattern across two theatres.

G. Several distinct phenomena under one popular label. The position the documentary record most cleanly supports: some Me 262 contacts misread as orbs; some ball lightning; some St. Elmo’s fire; some aviator disorientation; and some residual category of sightings not captured by any of these. The Air Ministry’s “still something of a mystery” formulation is the period record’s own version of this position.

What remains unknown

The chain of inquiry is the case. A US Army Air Forces night-fighter squadron generated a fourteen-incident report. XII Tactical Air Command could not explain it. SHAEF could not. The Air Ministry, asked to assess, put in writing that the matter was still a mystery and offered the Me 262 and flak rockets as a reach. SHAEF closed the file with “no further, or more definite, information.” The autumn 1945 interrogation of thirteen senior German aerospace and Luftwaffe figures produced no admission of a matching programme; no archival find since has produced one. Project Sign in 1948 treated the reports as prehistory. The Robertson Panel in 1953 proposed natural-phenomenon candidates without identifying anything.

The Air Ministry’s “still something of a mystery” was an admission against interest by an intelligence apparatus at the height of its wartime capacity, working from the testimony of its own crews and an Allied air force’s. The Robertson Panel’s candidates were proposals, and the panel said so in its own language about the name. The Pacific theatre B-29 record extends the same phenomenology to the other side of the war. The Vesco Feuerball thesis is a hypothesis without an archive.

What flew with the Beaufighters of the 415th over the Rhine in late 1944, and with the B-29s over Japan in 1945, has not been identified. The Air Ministry said so in writing on 13 March 1945. SHAEF said so on 18 March 1945. No agency has said otherwise since. The file is open.
