National Aeronautics and Space Administration · 94 pages · text from the file's own layer

This file, held under a National Aeronautics and Space Administration title, contains an English translation of the 1999 COMETA report "UFOs and Defense: What Should We Prepare For?", produced by a French association of former IHEDN auditors and first published in a special issue of VSD. It opens with a 2001 letter from Carol Rosin arranging a meeting. The report covers pilot testimonies, close encounters in France, GEPAN/SEPRA research and defense implications. Attached material includes a Leslie Kean article, a NARCAP description and a news item about a UFO at Barnaul airport.

From the source:Release of 2026-05-08 Incident: N/A. Released with redactions. NARA Record Group 255, catalogue id 413270. This file contains an independent report on UFOs written by the French association COMETA (previously published in the French magazine VDS in 1999), which details the results of a study by the Institute of Higher Studies for National Defence. The file also includes a letter from Carol Rosin in which she notes that she was spokesperson for von Braun during the last years of his life.

I Chapter 7 - Method and Results of GEPAN/SEPRA
I 7.1 Method Developed by GEPAN
I GEPAN developed an original method for studying rare, randomly occuning
phenomena. Meteorites are among these phenomena. Scientists have long refused to
consider sightings of stones that have fallen from the sky, which are generally reported by
I rural inhabitants. Fortunately, in 1803, the physicist Jean-Baptiste Biot conducted an in
depth investigation in the village of Laigle in Orne [Department] about three weeks after_it
was reported_ that stones had fallen from the sky. Biot examined numerous stones and
I certain evidence (broken branches, perforated roofs, fires) and questioned many
independent witnesses. He prepared a convincing report that gave scientific ~xistence to
meteorites.
I The method developed by GEP AN was approved by its scientific council. It basically
consists of identifying initially unknown phenomena and perfonning a joint analysis of four
I
types ofdata concerning:
- witnesses: physiology, psychology, etc.,
- testimonies: accounts, reactions to questions, general behavior, etc.,
I
- the physical environment: weather, air traffic, photographs, radar data, traces left on
the environment, etc.,
- the_psychosocial_environment: readings and beliefs of witnesses, possible influence of
I
the media and various groups on these witnesses, etc.
Gendarmerie reports often contain sufficient data in order to be able to identify the
phenomenon sighted. In many cases, the phenomenon turns out to be an airplane, a
I
planet, a satellite, etc. In other cases, a fairly large supplemental investigation is
conducted by GEPAN/SEPRA. An in-depth study can take up to two years. The analysis
of traces left on the environment may result in specialized laooratories being called on for
I
assistance (see the Trans-en-Provence and "Amaranth,, cases in Chapter 4).
Finally research was conducted in collaboration with the universities in order to perfect
the investigation method. CNES, out ofa concern for scientific precision, adopted the
term "UAP" instead of the term UFO, which is more well known but more restrictive.
GEPAN is the group that studies UAPs.
I 7.2 First Classification of UAPs (Unidentified Aerospace Phenomena)
I After a study is conducted, each case is classified by GEPAN/SEPRA into one of the
I following four categories, depending on the extent to which it has been identified:
- Category A: completely identified phenomenon,
- Category B: phenomenon that can probably be identified but which cannot be
I identified with certainty due to a lack of evidence,
- Category C: phenomenon that cannot be identified due to a lack of data,
- Category D: phenomenon that cannot be identified despite the abundance and quality
I of the data.
Category D UAPs represent 4 to 5% of the cases and are called UAP Ds. They include
sightings of phenomena, some of which were close to the ground1. within a few meters of
the witnesses. The strangest and most mysterious cases in this category are generally
