ALSACAT:

As its name suggests, 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 Bourtzwiller, on February 14, 1978:

Case number:

ALSACAT-1978-02-14-BOURTZWILLER-1

Summary:

Journalist Pierre-Louis Cereja published in the regional newspaper L'Alsace for February 15, 1978, an article about two UFO sightings in Bourtziller by the same witness, Christian Rupp, electrician, 17 year-old in 1978.

The previous evening, February 14, 2015, at approximately 7 p.m., he was walking his dog near the small park in the street of Dieppe in Mulhouse-Bourtzwiller, when he saw a flying object.

He had noticed it far off in the sky and had initially thought it was a plane that passed; so he continued his walk without paying attention.

But a few minutes later, he looked back and saw, about 5 meters above the roof of a house, a flat object with two headlights at the ends and a sort of triangle in the middle. Both headlights were producing a very white and very bright light, which he called a "industry white" in the words of his craft.

The lights went out and lit alternately. The UFO was stationary for about ten seconds above the ridge of the roof of the house before "disappearing" behind it.

The newspaper published this sketch as representing the UFO seen:

The article said that three years ago, in the same place but around midnight, Christian Rupp had already observed a UFO. He was then with his mother and neighbors in the street to follow the slow passage of a triangular-shaped object that moved, without light.

A UFO in the sky of Bourtzwiller?

A young electrician of 17 years old, Christian Rupp, brings his stone to the building since last night around 7 p.m., while walking his dog near the small park in the street of Dieppe in Mulhouse-Bourtzwiller, he saw a flying object.

At first, the young man had noticed far off in the sky a presence that he initially attributed to the passage of an airplane. So he continued on his way without paying attention. However a few minutes later, the young electrician turned around to see, about 5 m above the roof of a house, a flat object with two headlights at its ends and a kind of triangle in the middle. Both headlights were providing a very white and very strong light (an "industry white" according to the expression of the professional young man) that was flickering on and off alternately. The UFO remained motionless for about ten seconds above the ridge of the roof before disappearing behind it.

Three years ago, in the same place already but that time around midnight, Christian Rupp had already observed a UFO. He was then with his mother and neighbors in the street to follow the slow passage of a triangular shaped object that moved without light however.

[Ref. cv2:] CHRISTIAN VALENTIN:

Former journalist Christian Valentin published in 2012 a very interesting book telling the story of UFO sightings, flying saucers sightings, in Alsace, from the beginning to 1980.

In this book, he reports that on Monday, February 13, 1978, there was an observation in Bourtzwiller, reported like this in the newspaper L'Alsace for Wednesday, February 15, 1978:

Discussion:

As often with cases only reported as a newspaper article, very essential information is omitted.

According to the sketch, we are dealing with a non-human flying machine, so, an alien craft.

But who made the sketch? Was it the witness, or is this a free interpretation of some draftsman who did not see the UFO? We are no told.

Actually the thing could have been a human machine, id we do not take the sketch for a reliable representation. For example, the machine could have been a helicopter.

To confirm or deny this, we should have at least two pieces of information: was the apparatus making noise, or was it silent, and how far from the witness was it?

Again, we are not told, although this information could have been easily collected, obviously.

Was this a phoned report? Did anyone meet the witness directly? What was heis profile, his credibility? What was the total length of observation? Why don't we get to know whether people in the area saw of heard something? so many questions...

What a pity!

There are several areas that can be called a "small park" along rue de Dieppe in Mulhouse-Bourtzwiller (green line).

A daylight view in 2015 of that street.

Another daylight view in 2015 of that street.

Bourtzwiller was a town of its own in the Haut-Rhin, but was then incorporated into the town of Mulhouse; becoming its most populous district.

Evaluation:

Unidentified, but sparse information.
