The essentials in 30 seconds
En July 1999, a 90-page private report shakes France: “UFOs and Defense: what should we prepare for? », said COMETA report. Its authors are not amateurs: former auditors of IHEDN - generals, an admiral, armaments engineers -, prefaced by General Bernard Norlain, former commander of the Tactical Air Force. Addressed to the Prime Minister and the President of the Republic, it concludes that for a core of unexplained cases, the extraterrestrial hypothesis is “the most coherent” — the most daring declaration ever signed by French soldiers of this rank.
What the report is — and is not
Capital clarification: COMETA is a report private of an association, not an official document of the French State - even if its authors are former senior officials and it was handed over to the highest authorities. His conclusion is a authors statement, not an established fact: “the most coherent hypothesis” is not proof, and the report itself recognizes this. Our grid applies: the document exists (fact), its conclusion commits its signatories (declaration), the nature of the cases remains unestablished (hypothesis).
Why it still matters in 2026
COMETA relied on the solid cases of French casuistry — Trans-en-Provence, Valensole — and on the data of GEPAN/GEIPAN. Twenty-seven years before the Pentagon opened its 334 files, French officers were already asking the question in terms of defense. The COMETA question — “what should we prepare for?” » — is exactly what Washington is asking itself today.
Who signed — and why it matters
The COMETA association (“In-depth Studies Committee”) brings together former auditors of IHEDN, the Institute of Advanced National Defense Studies. Among the contributors and supporters: General Bernard Norlain (former commander of the Tactical Air Force and director of IHEDN), General Denis Letty (fighter pilot, initiator of the project), general armaments engineer Pierre Bescond, and André Lebeau, former president of CNES. Three years of work, hearings of pilots and radar operators, access to GEPAN/SEPRA files. It is not the quality of the signatories that makes a conclusion true — but it does prohibit the document from being brushed aside.
What the report contains, chapter by chapter
First part: the cases — Lakenheath (radar-visual, 1956), the aerial incident of Tehran 1976, the RB-47 (1957), Trans-en-Provence, the “Amarante” case, the Belgian wave. Second part: the state of knowledge — radar, propulsion, hypotheses. Third part: defense implications, with concrete recommendations (monitoring, European cooperation, pilot information). The report explicitly rules out generalized collective psychosis and only natural phenomena for a core group of cases — while acknowledging that no definitive material evidence exists.
