METEORS  [3 parts PDF dossier (in French): Astronomers and UFOs (1986), Singular Meteors and Ufology(1994), These strange Meteors (1996)]  (added July 2013)

Marc Hallet

Under the generic title “Meteors”, a PDF file of three books that Marc Hallet published between 1986 and 1996. The purpose of these three books, which completed each other,  was to show that contrary to what tell ufologists, meteors can take many different appearances and therefore can be misidentified as UFOs. Some researchers studying UFOs from the past have repetitively been mislead in the past.
[Astronomers and UFOs p3, Singular Meteors and Ufology p74, These strange Meteors p115]
