ACUFO is my comprehensive catalog of cases of encounters between aircraft and UFOs, whether they are "explained" or "unexplained".

The ACUFO 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.

Koblenz, Germany, on February 19, 1944:

Case number:



In his 2007 book "Strange Company" about the military pilots UFO encounters during WWII, author Keith Chester indicated that there was a sighting on February 19, 1944, over Koblenz in Germany.

It was reported that a silver cigar-shaped object like an airship was observed at a distance of 2,000 - 3,000 yards. It flew on a parallel course, at the same altitude and gradually dropping astern. It appeared to turn towards the aircraft, passing from the right to the left.

The source was indicated as a summary report of flak liaison officers of the US Army Air Force dated March 7, 1944.

The Website Saturday Night Uforia, in the 2010's, reported on this sighting in the same manner.

Case 33

February 19-20, 1944

Coblenz and Aachen, Germany

A silver cigar-shaped object like an airship was observed in Coblenz at a distance of 2-3,000 yards. It flew on a parallel course, at the same altitude and gradually dropping eastern. It appeared to turn towards the aircraft, passing from starboard to port. In Aachen, it was reported that the object a line of windows along its bottom.

Sources: Consolidated Flak Liaison Officer report, 7 March 1944, N░205/ Strange company, Keith Chester


The website indicates that on the night of February 19/20, 1944, which saw massive raids against multiple cities in Germany, came "many reports of unusual phenomena" described in the Consolidated Liaison Flak Officer Report of March 7, 1944. Most "phenomena" reports in this summary undoubtedly related to conventional anti-aircraft weapons. But there were two intriguing incidents.

One occurred near Koblenz, of a "silver cigar-shaped object like an airship," which was seen at a distance of about 2-3,000 yards from the aircraft, flying on a parallel course at the same height and gradually dropping astern; it appeared to turn in towards the aircraft, passing from starboard to port well astern.

[Ref. nip1:] "THE NICAP WEBSITE":

[1944] Feb. 19/20, 1944; Coblence and Aachen, Germany

Silvery cigar-shaped object like an airship; appeared to be a line of windows along the bottom of the object. (Page 60 Ref.1)

The reference 1 is described at the end of the document as "Strange Company (2007), Keith Chester".


Date: Feb. 19/20, 1944

Location: Coblence and Aachen, Germany


Summary: Silvery cigar-shaped object like an airship; appeared to be a line of windows along the bottom of the object.

Page 60 Ref.1

Aircraft information:

No information on the involved plane(s) is available. But US Army Air Force raids over Germany in those times were performed mostly using Boeing B-17 "Flying Fortresses" or Consolidated B-24 "Liberators"; both by daytime, both armed with a number of machine guns for defense against enemy fighter planes.



The information is meager; which is only normal since it apparently came from a "Summary" report aimed at collecting German flak operations during the US bombers raid.

One may think, given the description, that this was a "Zeppelin" airship. But the Germans did not use or build any such airship in WWII.

On May 6, 1937, the "Hindenburg" Zeppelin caught fire when it landed at Lakehurst, USA: thereafter, no Zeppelin or other airship were built again until long after the end of WWII.


Possible extraterrestrial craft.
