PENTAGON UFO FILE · DOCUMENT255 413270 UFO's and Defense What Should we Prepare For
This file is a foreign document that ended up in U.S. government records. Its core is UFOs and Defense: What Should We Prepare For?, the report produced in France by COMETA, a private association, and first published in a French magazine in 1999. The release lists the file as held by NASA, and some of its pages are redacted.
What the COMETA report is
COMETA was made up largely of people with defense and aerospace backgrounds, and its report is linked to France’s “Institute of Higher Studies for National Defence,” known by its French initials IHEDN, a body that runs courses for senior officials. The file’s description says the report sets out the results of a study by that institute. It is important to be precise here: COMETA was an independent group, and its report was not an official position of the French government.
The report is widely cited because of its authors’ credentials and its argument that UFOs should be treated as a defense question. The PURSUE description does not summarize its conclusions, so this page does not either.
The Carol Rosin letter
Bundled with the report is a letter from Carol Rosin, who says in it that she was a spokesperson for the rocket engineer Wernher von Braun in his final years. The description does not say to whom she wrote or why, and her claim about her role is her own. For other material on how governments have handled the subject, see NASA’s replies to UFO mail from Congress and the White House.
