Hi all,


Yesterday, I posted a piece ( click here to read) on the SIGMA technical committee of the French learned body, 3AF (click here). Last night I came across some additional information, which I thought I would share here.

The latest article, which I found on the 3AF website was titled "SIGMA2: a mandate, structure, work plan and action." It is written by Luc Dini, Manager of the SIGMA2 technical committee, and dated 21 July 2014.


"SIGMA2...will refer to the evidence and representations accompanied by physical data from databases, physical analysis, including new theories, focusing on observations of PANs likely to be exploited scientifically."

SIGMA2 will not conduct parallel field investigations like those by GEIPAN, but will instead focus on "unsolved cases." (GEIPAN type D.) It will also build technical and scientific networks in France and abroad, to examine possible causes. Lastly, SIGMA2 will also seek overseas cases, unlike GEIPAN.

A rough translation of GEIPAN's type 'D' is:

"The PAN D correspond to investigations that failed to advance an explanation for the observations reported, despite the quality and consistency of data and testimonials. These are, in the true sense, "unidentified aerospace phenomena.""

Work plan:

A three year work plan was set out in the article, which will include:

1. A literature review of works that offer a scientific analysis.

2. Gaining an understanding of the international environment, and making contact with new data or studies.

3. An operational database.

4. A 'contact group' whose main task will be to establish links with organisations able to "provide interesting case studies."

The article mentions that the GEIPAN database has 232 cases in their category 'D.' SIGMA2 have selected a few to study, which include:

* 28 January 1994. Flight AF3532 (details in French click here.)

* April 2007. Aircraft crew see UAP near the Channel Islands (details in English click here.)


It is so refreshing to see serious research of this nature being carried out in France; as compared to no official government or learned body interest, here in  Australia.

2017 update:

I checked the 3AF website on 1/10/2017. Sigma2 is still listed there, but the 'SIGMA2: a mandate, structure, work plan and action,' written by Luc Dini, Manager of the SIGMA2 technical committee, and dated 2014, as above, is no longer to be found.

  1. Thanks..an interesting range of groups in France. The contrast between different language areas is interesting
