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 Basel - Mulhouse, on October 31, 2005:

Case number:

ALSACAT-2005-10-31-BALEMULHOUSE-1

Summary:

On November 12, 2005, a member of the Alsatian ufology association SPICA posted on a UFO sightings forum a testimony that his association had received.

The witness said that on Sunday, October 31, 2005, at night, he was driving "on a French motorway from Basel to Strasbourg (E-25 maybe?)."

Between Basel and Mulhouse, about ten kilometers north of the Basel-Mulhouse airport, at about 8 p.m., his attention was drawn to an object in the sky, reminiscent of an airliner in landing approach.

After a few tens of seconds, he had approached the object enough to find that not only it was stationary at about a hundred meters from the ground according to his estimate, "almost exactly above the highway", but it also let clearly see three round white lights arranged in a triangle, with a smaller red irregularly flashing light, more or less in the center.

He estimated that the diameter of the object must have been about 15 to 20 meters, noting that it is difficult to estimate this precisely.

He then "instantly remembered the famous Belgian wave of UFOs in the early 1990s," saying that this object had the same look as those he had seen on the TV news.

He said the sky was clear at the observation place, the outside temperature was around 12-15°C.

He ensures that he is someone rational, but that he was puzzled by what he saw, and hoped that "other motorists who saw the same thing that night will also give a testimony because I'm very curious to know what it was."

This is the witness report received on our SPICA website

Hello,

I was driving by car on Sunday, October 31, 2005 in the evening, on a French motorway from Basel to Strasbourg (the E-25 maybe?). Between Basel and Mulhouse, I would say about ten miles north of the Basel-Mulhouse airport, around 08:00 p.m., my attention was drawn to an object in the sky, reminiscent of an airliner in landing approach.

After a few tens of seconds, I had approached enough of the object to find that not only it was stationary at about a hundred meters from the ground I would say, almost exactly above the highway, but that it clearly let see 3 round white lights arranged in a triangle, with a smaller red light flashing irregularly, more or less in the center. At first glance, I would say that the diameter of the object must have been about 15 to 20m, hard to say exactly.

Then I instantly remembered the famous "Belgian wave" of UFOs in the early 1990s. This object had the same appearance as those I had seen on the news...

Some details on the conditions of observation:

date : Sunday, October 31, 2005

hour : at about 08:00 p.m., approximately

weather : clear sky at the place of the observation

external temperature: i would say about 12 - 15°C (my car does not have an onboard computer)

I am a rational, but I must say that I am disturbed by what I saw. I hope that other motorists who saw the same thing that night will also give a testimony because I'm very curious to know what it was.

Best regards,

MULHOUSE (68) Monday, October 31, 2005

Testimony received by SPICA

At around 08:00 p.m., my attention was drawn to an object in the sky, reminiscent of an airliner during landing approach. After a few tens of seconds, I had approached enough of the object to find out that not only it was stationary at about a hundred meters from the ground I would say, almost right above the highway, but also that it clearly let see 3 round white lights, arranged in a triangle, with a smaller red light flashing irregularly, more or less in the center.

Discussion:

The motorist was, he said, on the highway at about ten kilometers to the north of the Basel Mulhouse airport.

The map allows to understand the situation: he was about the blue dot is on the A35 motorway, and this is perfectly in line with the runway of the airport, visible on the lower right part of the map.

There, very often, airliners in landing approach seem to be "stationary" to motorists and are interpreted as UFOs because of this illusion.

I know this perfectly well: I must have made the same trip there more than a hundred times, often at night, for example when going home after skiing in the Swiss Alps, and I saw the apparent immobility of approaching airplanes.

So, with a witness aware of the Belgian UFO wave, indicating that he initially thought it was an approaching aircraft, for me, the case is clear: this is almost with certainty another case of an airliner in landing approached mistaken for a UFO.

It is a fact that as presented on TV, the UFOs of the Belgium flap were reduced to something like this, three bright white lights and a flashing red light in the middle. But the reports were very often not that simple at all. The "white lights" were often projectors directed downwards to the ground, the triangular shape was often really visible, the immobility was often real, noted by witnesses standing near the UFO, not driving on the approach path of landing airliners. Other features such as a lack of sound when it should have been heard if it was a plane, other details such a the red light flying off the main structure, make it impossible to decide they were all just planes in landing approach.

My documentation of the "Belgium flap" is here.

Evaluation:

Landing plane.
