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 Strasbourg, on March 17, 1959:

Case number:

ALSACAT-1959-03-17-STRASBOURG-1

Summary:

A questionable Spanish encyclopedia of 1996 about "mysteries" says that on March 17, 1959, unexplained explosions were heard above Strasbourg. For this same date, a ufology catalog on the web says there was a UFO sighting of "nocturnal light" type in Strasbourg, stating that it comes from the computer catalog of Jacques Vallée.

[Ref. ev1:] ENRIQUE DE VICENTE:

Cet auteur d'une encyclopédie sur les mystères divers, parue sous forme de CD-Rom, écrivait qu'à Strasbourg en France le 17 mars 1959, on avait entendu de mystérieuses explosions au-dessus de la ville, qui n'ont pas eu d'explication:

17 Marzo 1959 Estrasburgo Francia Misteriosas explosiones fueron escuchadas sobre esta ciudad. No se encontraron explicaciones al respecto.

[Ref. ud1:] "UFODNA" WEBSITE:

17 March 1959 20:30

Strasbourg, Alsace, France

Hynek rating: NL

The sources are indicated as: "Vallee, Jacques, Computerized Catalog (N = 3073)."

Discussion:

According to [ev1], there would be no UFO there but "explosions"; for [ud1] it is a UFO sighting of the "nocturnal light" type...

I found no othe source other than these two meager and unreliable ones.

Admitting the reality of the facts - which is doubtful - I find that there has been no earthquake in Strasbourg on this date.

I found that the newspaper L'Est Républicain for March 14, 1959, on page 6, reported the discovery of fifteen tons of shells of WWI, in Héming in the Moselle, near the Paris-Strasbourg line. Were they detonated in a center in Strasbourg?

A demining company was created in 1959 precisely in Soultz-sous-Forest, 30 kilometers north-west of Strasbourg.

Evaluation:

Probably not UFO-related.
