Lunéville, France, on December 27, 1944:

Case number:



In the fall and winter 1945, Intelligence Officer Fred B. Ringwald was attached to the 415th Night Fighter Squadron, stationed in the Dijon region in France; which carried out night intrusion missions into enemy territory on the Rhine valley. Having himself seen with others unexplained luminous phenomena during a mission, he had collected a series of other testimonies to send a summary about it for the Tactical Air Command of the U.S. Army on January 23, 1945.

Among the cases he listed, he indicated that on the night of December 27 to 28, 1944, 8 miles northeast of Lunéville, France, three series of three lights had been seen at 7:10 p.m. They were of red and white colors, one series was to the right of the aircraft and the other series to its left, at 1,000 feet to 2,000 feet, towards the rear of the aircraft and approaching the altitude of 10,000 feet. The plane had descended to 8,000 feet, and the lights had gone out. The plane's radio operator had called "Churchman" - code name for the ground radar station - to see whether there was anything in the area, but he had received a negative response.

The sighting was previously noted in the 415th Night Fighter Squadron's December 27-28, 1944 operations log, where it was noted that on December 28, 1944, "the first patrol saw 2 sets of 3 red and white lights. One appeared on the port side, the other on the starboard side 1,000 to 2,000 feet astern and they were getting closer. The Beau [their plane, a Bristol Beaufighter] sped away and the lights went out. Nothing on the GCI [ground radar station] screen at that time."

Night of 27-28 December 1944 - Eight miles NE of Luneville at 19:10 hrs. saw three sets of three lights (red and white) one on starboard and one on port from 1000ft. to 2000 ft. to rear and closing in at Angels 10.

* Foofighters is the name given these phenomenon by combat crews of this Squadron.



Three nights later [than November 23, 1944] they were again seen by a U.S. pilot flying in the same area.


The bulletin of "Citizens Against UFO Secrecy" (CAUS) published that they managed to get the first Foo Fighters official reports in the War diaries of the 415th Night Fighter Squadron. Extracts were cited, such as:

December 28 [1944]- "The Ops report says: '1st patrol saw 2 sets of 3 red and white lights. One appeared on port side, the other on starboard at 1000 to 2000 feet to rear and closing in. Beau peeled off and lights went out. Nothing on GCI scope at the time.' And then again: 'Observed lights suspended in air, moving slowly in no general direction and then disappeared. Lights were orange, and appeared singly and in pairs. These lights were observed 4 or 5 times throughout the period.'"


December 28: "The operations report says: "first patrol saw two rows of three red and white lights. One appeared on the port side, the other on the starboard side at 1000 and up to 2000 feet astern, approaching. Beau picked up and the lights went out. Nothing on the GCI screen at this time." Then, again: "Saw lights hanging in the sky, moving slowly in no precise direction, which disappeared. They were orange, and moved in pairs or alone. They were observed four or five times."


1944, December 28


(415th bombers) The first patrol saw 2 sets of 3 red and white lights, one appeared on the right side, the other straight ahead, at an altitude of 1000 to 2000 feet. When Beau (pilot) applied the throttle for the interception, the lights went out. Nothing on the radar at the moment. Next, lights are seen hanging in the sky in an erratic slow trajectory. They are orange in color, appear singly or in pairs. These lights are observed 4 or 5 times by the patrol. (Greenwood, Barry; Just Cause, no. 32, p. 1, June 1992.: Source: microfilm roll containing the Unit History and War Diary of the 415th was obtained from the U.S. Air Force. Frames 1613 and 1614.)


Case 74

December 27-28, 1944

8 miles northeast of Luneville, France

At 19h 10, the crew of a Beau fighter from the 415th Night Fighter Squadron while patrolling at 10,000 feet saw three sets of three lights (red and white). The lights were closing in fast, one on starboard and one on port from 1,000 to 2,000 feet to the rear and closing in at Angels 10 (10,000 feet altitude). Taking evasive action, the pilot peeled off and dropped his aircraft down at Angels 8 (8,000 feet) and the lights went out. The crew called GCI to see if there was anything in the area and they received a negative reply. Not far away, around the time, the crew of another 415th NFS aircraft reported orange lights suspended in the air, "moving slowly" before disappearing. The pilot said the lights appeared singly and in pairs and he observed these lights four or five times.

Aircraft information:

The Bristol Type 156 "Beaufighter", nicknamed "Beau", was a British multi-role aircraft developed during WWII. It was originally conceived as a heavy fighter variant of the Bristol Beaufort torpedo bomber; it proved to be an effective night fighter, which came into service with the Royal Air Force (RAF) during the Battle of Britain.

Originally, armament consisted of four 20mm cannons and six 0.303-in machine-guns but many variants were built; for example, versions had the ability to additionally carry eight rocket projectiles, some had a Vickers 'K' gun, Beaufighter TF.Mk X was used for anti-shipping operations.

The Beaufighter Mk VIF was fitted with the Mark VIII radar.

Below: Beaufighter Mk VIF of the 415th Night Fighter Squadron.

Beaufighter VIF 415th NFS.

The Beaufighters served with the US Army Air Force until the end of the war, but most were replaced by the P-61 "Black Widow" beginning on March 20, 1945.


Lunéville was liberated on September 18, 1944. The incident took place during the Battle of the Bulge. The Germans were then attacking to the north of Luxembourg and were to the north of Saarbrücken in Germany, the front line being there more than 60 kilometers from the place of observation.


The strangeness of this case is numerous.

The lights could hardly be German planes or other German devices because they erre coming from below, and this, in the region of Lunéville in France, territory then totally under American air force control.

The lights couldn't have been enemy flak fire at all, because there were no more enemies on the ground in that area at that time.

The lights were seen but not detected by the ground radar station, which is abnormal if they were German planes. This characteristic is common in sightings of "Foo Fighters" from the fall - winter of 1944 - 1945 in this sector.

The lights could not be "St. Elmo's fires", as some had suggested to explain such sightings, because they were approaching the plane. St. Elmo lights would have remained fixed on the ends of the plane from end to end.

If one intends to plead that these were "German weapons" whatever they were, the objection is, as in all other cases of "Foo Fighters", that these "weapons" had absolutely no effect.

All sorts of other explanations can be ruled out. For example, if we want to think that these were German Messerschmitt "Komet" rocket planes, it must be ruled out because these planes could not operate at night, because their range, with their flight capacity of only 7 minutes, ruled out their operation in liberated territory, because their "light" was not a light but a white streak, never red.

If it is argued that these were flames from the jet engines of German planes, it is necessary to explain how they could be visible with planes approaching from the rear. They should have flown "in reverse"... moreover, the exhausts of the only German jet night fighter which could have operated there at that time, the Messerschmitt Me-262, were very discreet, and bluish - white in color, never red.


Possible extraterrestrial craft.
