France's National Space Studies Centre (CNES) is to put its UFO archive online this spring.
The group within the organisation known as the Rare Aerospace Phenomena Study Department ( SEPRA ) has been collecting reports of UFO sightings and now has over 6,000 documents relating to "strange sightings".
Jacques Arnould, project leader at CNES , said that the organisation will put its whole archives online for world viewing by mid-February.
"Often the [sightings] are made to the Gendarmerie, which provides an official witness statement, and some come from airline pilots," Arnould told Reuters.
The reports cover some 1,200 UFO sightings within French national borders, and represent 30 years of investigations.
