ACUFO:

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.

Emden, Germany, on December 11, 1943:

Case number:

ACUFO-1943-12-11-EMDEN-1

Summary:

In their 2002 book "Out of the Shadows", Dr. David Clarke and Andy Roberts indicated that their research in the archive of the British Public Records Office let them find that the December 31, 1943, issue of "Bang On", the newsletter of 115 Squadron, ran a short piece simply titled 'Phenomena'; which said:

"Under this heading there occur from time to time reports of weird and wonderful apparitions seen during our (and the American) attacks on Germany. We have asked our local Inner Circle bloke to comment on the latest species of wizardry. Here is his story... believe it or not..."

This 115 Squadron newsletter mentioned two sightings, one of them was:

"On the 11th December the Yanks paid one of their daylight visits to Emden. Visibility was GOOD and the weather clear. An unidentified object was seen in the target area. It was about the size of a Thunderbolt and passed 50/75 yards beneath the formation. It flew STRAIGHT AND LEVEL (no, chaps, it was not a Lane gone mad) at a terrific speed, leaving a streak like a vapour trail which was all white and which remained visible for a long time. The object passed so quickly that the observer could not determine it more accurately!"

A couple of paragraphs later, after some general comments about the raid, the article continues:

"In another attack... this time on Bremen... there were many reports of "silver and red discs above the formations". These have been seen before but up to now no-one has been able to decide their purpose. Suggestions please." (Source Andy Robert's research at PRO)

The authors indicate that although the introductory paragraph made it clear that "weird and wonderful apparitions" were not uncommon, no one in 115 Squadron knew what their origin was and the editor wrote that "Suggestions will be welcome, serious ones, as to what this Loch Ness Monster of Emden might have been."

Case 24
December 11, 1943

Edmen, Germany

During a daylight raid over Edmen, the bombers were approaching the target between 2 1,000 and 24,000 feet altitude when crews observed and unidentified object. The object was described as being about the size of a thunderbolt aircraft which passed 50-75 yards beneath the formation flying straight and level at a terrific speed. It left a streak like a vapour trail, which was all white and remained visible for a very long time. The object passed so quickly that the witnesses could not describe it better.

Comment: It was probably a German jet-propelled aircraft.

[Ref. tgd1:] TIMOTHY GOOD:

This author indicates that according to a semi-humorous item in an RAF news sheet, classified secret, an unknown aircraft was observed during a USAAF daylight bombing raid on Emden on 11 December 1943. Visibility was good and the weather was clear. The report is cited by the editor:

An unidentified object was seen in the target area. It was about the size of a Thunderbolt and passed 50/75 yards beneath the formation. It flew STRAIGIIT AND LEVEL (No chaps it was not a lanc [Lancaster] gone mad) at a terrific speed, leaving ii streak like a vapour trail which was all white and which remained visible for a long time, The object passed so quickly that the observer could not determine it more accurately.

Aircraft information:

Nothing is said about the plane in which the witnesses were, except that the report came from the "Yanks". i.e., US airmen. As the No 115 Squadron was a RAF night bombers squadron, it would be reasonable that the US airmen refered to were a USAAF daytime bomber crew, thus operating B-24 or B-17 bombers.

This incidentally supports that the sighting did take place during the day.

Discussion:

In their 2002 book [dcr1], Dr. David Clarke and Andy Roberts made some points about such kind of sightings:

In this case, the short observation distance of 50 - 70 meters and the mention that the object was the size of a "Thunderbolt", mean that the object should not have been "flak" nor glitter to deceive the radars.

"Thunderbolt" was the name of the American single-seat fighter plane Republic P-47; its wingspan was 12.40 meters and its length was 11.03 meters. It was bulkier than other fighter planes, so that this remark in the report would mean that the UFO was just a bit over the usual size of a fighter plane.

It also suggests that, although mysterious, marvelous, this object was of the nature of a plane.

The mention of the white trail that remained visible for a long time is undoubtedly what motivated Dominique Weinstein's idea that it was probably a German jet plane.

It is therefore up to me to draw up an inventory of German aircraft which could have emitted a trail by jet engine or rocket engine near Emden in December 1943.

Germany attempted to develop a number of surface-to-air missile systems: Enzian (radio-controlled, 1943), Rheintochter (solid fuel rocket, first tests in August 1943), Henschel Hs-117 "Schmetterling" (radio controlled, first tests May 1944), "Wasserfall" (somewhat similar to the V2, first tests March 1943, failure) "Feuerlilie" F25 and F55 (first test launches in mid 1944). None of them saw operational use, not even at the end of World War II.

None were flying "straight and level."

There is no shortage of more or less successful projects for strange German flying machines which, due to their reactors or rockets, could be suspected of being considered as causing "lights", but here, only one remains to be seen. consider, the Messerschmitt Me-163 "Komet", the only operational rocket fighter plane during World War II, which was put into service only in April 1944.

But tests began in May 1941, in Peenem nde.

The concept began in 1937, the idea was to use a classic glider, but equipped with a rocket engine. The plane would be based on the Lippisch Delta IV "DFS 39" wooden glider, but it was ultimately Messerschmitt who would build the first airframe, metallic. This was completed at the beginning of 1940 and it was sent to Peenem nde-West to receive its rocket engine. The wingspan was 9.32 m.

The first test flight took place on September 1, 1941, with success. The 2nd took place on October 2, 1941, and broke the world speed record by flying at 1004 km/h (624.2 mph) without damage. The dates of the following tests are poorly documented, but we can think that there may have been one on December 11, 1943.

The tests, notably for reasons of very strict secrecy, had all taken place in Peenem nde, on the north-eastern coast of Germany, while Emden is located on the western border, 430 km from Peenem nde. The "Komet" had a flight autonomy of a few minutes, before having to land by gliding, and it is therefore excluded that it could have flown from Peenem nde towards Emden at the end of 1943.

However, the first active unit in charge of testing the "Komet" in operational conditions, the Erprobungskommando 16 (Service Test Unit 16, EK 16) had received a first copy, and was based at the Bad Zwischenahn airfield from August 1943 to August 1944.

And it turns out that this Bad Zwischenahn airfield is only 58 km southwest of Emden.

Map.

So I think entirely possible that what the aviators saw was a Messerchmitt 163A "Komet" with the trail of its rocket engine, white and clearly visible in broad daylight.

Let s read again:

"Visibility was good and the weather was clear. An unidentified object was seen in the target area. It was about the size of a Thunderbolt and passed 50/75 meters below the formation. It was flying STRAIGHT AND FLAT (no, guys, it wasn't a Lanc [Lancaster] gone crazy) at a terrible speed, leaving a trail like a vapor trail that was all white and remained visible for a long time. passed so quickly that the observer could not determine it more precisely!"

The report describes very accurately the passage of a Me-163 Komet, thus I make it the probable explanation for this observation.

Me-163 Komet.

I still have to explain why I do no think it was an Arado Ar-234 "Blitz", as it made its first flight on June 15, 1943.

Evaluation:

Probable Messerschmitt Me-163A "Komet".
