Capt. Thomas Pedersen said the military released the documents after growing weary of journalists asking questions about them, the Copenhagen Post reported Friday. Advertisement "We decided to publish the archives because frankly there is nothing really secret in them," Pedersen said. "The Air Force has no interest in keeping unusual sightings a secret. Our job is to maintain national security, not investigate UFOs." The Air Force said the archives contain details of unexplained events occurring between 1978 and 2002, before the job of chronicling UFO sightings went to a group called Scandinavian UFO Information.
