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.

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
