ALSACAT is my comprehensive catalog of UFO sighting reports in Alsace, the region is the North-East of France, whether they are "explained" or "unexplained".

The ALSACAT catalog is made of case files with a case number, summary, quantitative information (date, location, number of witnesses...), classifications, all sources mentioning the case with their references, a discussion of the case in order to evaluate its causes, and a history of the changes made to the file. A general index and thematic sub-catalogs give access to these Alsatian case files.

Case of Ingwiller, on January 14, 1945:

Case number:



The 415th Night Fighter Squadron (415th NFS) of the US Army Air Force was established in February 1943 and conducted patrols in the Mediterranean and north-west Europe combat zones during WWII.

In December 1944, and until the Germans lost Alsace, members of the 415th NFS made several reports of what they called "Foo-Fighters" in the Rhine valley, as recorded in a report for January 30, 1945, by the Tactical Air Command intelligence officer Fred Ringwald, who had himself been one of the first witnesses of these "balls of light".

In this report, a case is recorded for the night of 14-15 January 1945 at 08:00 pm, saying that a large orange glow in the sky that was seemingly 5 feet in diameter was observed close to Ingwiller, at 6000 feet.

The report stated that in all cases where the pilot requested a confirmation by ground radar, he received a negative answer.

The case was cited in the UFO literature, wrongly located in Germany and with the misspell of the original report; where the location was called "Ingweiller" instead of Ingwiller.

The 415th Night Fighter Squadron of the U.S. Air force was formed in February 1943 and it carried out patrols in the Mediterranean and then North-west Europe during World War II.

In December 1945, members of the 415th made multiple reports of what they called "foo-fighters", as recorded in a January 30, 1945 report to Tactical Air Command by intelligence officer Fred Ringwald.

Here are the parts of that report about the sighting in their case file:


1. In compliance with paragraph 3 of 1st Incl., the following extracts from the Sortie Reports of various pilots who have encountered the Night Phenomenon are submitted for your information.

[... other sightings ...]

Night of 14-15 January 1945 - "Observed a large orange glow in sky appear. 5 ft. in diameter in vicinity of Ingweiller [sic, "Ingwiller"] at 6000 ft. at 20:00 hours."

[... other sightings ...]

2. In every case where pilot called CGI Central and asked if there was a Bogey A/C in the area he received a negative answer.

Note: the report lists several other sightings in Alsace, those have their own case files. It also lists several sightings whose location is unknown to me as they were coded such as "Q-9050", "Q-1378" etc... these locations may have been over Alsace, over elsewhere in France, or over Germany. As I did not find the meaning for these locations codes, I cannot include these other sighting in ALSACAT for now.

Crews of the 415th Night Fighter Squadron of the U.S. Army Air Force reported their nocturnal observations of what they called "Foo Fighters" above the Rhine valley then occupied by the Germans, between November 1944 and April 1945, as their base was in Dijon and Ochey in France.

Their reports apparently ceased when the Germans lost Alsace.

"Ingweiller, Germany" is an incorrect location. Ingwiller is a French village in the Bas-Rhin department, Alsace region.

In Merzig, in the Saarland, 80 kilometers northeast of Ingwiller, there was a launch pad for V-2 rockets. This is the known launch site closest to the place of observation; but it is documented that the launches there ended in October 1944. However, it should be kept in mind that at that time the V-2 had logistics allowing them to be launched from anywhere.

The description of the observation is obviously too meager to prove that the airmen saw a V-2 rocket; but it is also too meager to allow to discard this explanation.


Possible V-2 rocket.
