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 the Socorro (New Mexico) case, which is similar to the Trans-en-Provence case, but the I critical overview of which would needlessly weigh down this report. One strong conclusion emerges from this set of facts: some UAP Ds do seem to be completely unknown flying machines with exceptional perforrnances that are guided by a I natural or artificial intelligence. I Chapter 8 - UFOs: Hypotheses, Modeling Attempts 8.1 Partial Models I Credible sightings ofaeriaJ objects can be reinforced by plausible technical explanations I - of the phenomena reported. Among the most striking observations in relation to the current state of our_knowledge, we cite: aerial movements canied out silently with very rapid accelerations and/or very high speeds, - the shutting offof the engines of nearby land vehicles, - the locomotive paralysis of witnesses. Insofar as the sightings that are the most well documented, and the most credible owing to the obvious competence of the witnesses, come from aircraft pilots, it is their sightings ofaerial movements, sightings which are, moreover, supported by radar plots, that should be explained first. I 8.1.l Travel I There are, from the standpoint of the concept, various principles of propulsion that do not require propellers or jet engines that could thus be silent. The most advanced uses I magnetohydrodynamics, abbreviated MHD, but many others can also be considered. We will review these. 8.1.1.1 MHD Propulsion I The principle ofMHD propulsion, which cannot be envisioned in a vacuum, consists of I causing an electrical current to flow in the medium surrounding the .ship At the same time, the ship emits a magnetic field. According to Laplace' s law, this field exerts a force on the current and thus on the medium in which it is flowing; this is the principle of most electric motors. The medium being thus displaced in relation to the ship, it is in fact the latter that undergoes, by reaction, a force that enables it to be propelled. It remains to I create the necessary field and current: I - for the magnetic field, this is easily accomplished by installing windings (like those in electric motors}, in which a suitable electrical current travels, in or under the walls ofthe ship, I - for the electrical current, all depends on the medium. In sea water it is easy to cause a current to flow using electrodes positioned on the hull. This is why MHD propulsion has been experimented with, so far successfully, in the I United States and Japan on both surface and submarine ship models. In air, which is naturally insulating, it is more difficult to cause an electrical current to flow, but air can be made conducting by using, for example, strong electric fields generated here again by suitable electrodes (air, when rendered conducting, can become more or less I I
