In 1995, a report (*) has been written by an organization that is an official emanation of the Ministry for the Defense dealing with the problem of UFOs, and presenting in an up to date manner the official position of the French Military of this issue. The file is not exactly secret, a French citizen might obtain it by asking for it at the Ministry of Defense. But on the other end the text is copyrighted, and it is illegal to reproduce it.
The aforementioned file devotes a paragraph about the events at Colares under a section dealing with the possibilities of direct threats related to UFOs. The case is quoted as an example that such threats do exist, that some cases are not just observation of objects but present facts of a much more worrying nature.
The French Defense in the presents the case by a summary in a dozen lines of what Jacques Vallée, quoted as the source, learned when he investigated the phenomenon. The medical effects on the witnesses are mentioned, including five deaths caused by the "Chupa-chupas", and, still quoting Jacques Vallée as source, the report of the Defense mentions that the Brazilian Air Force carried out a study mission in the area, which lead to a written report.
(*) Not the well known "COMETA" report which was not an official report.
