The Sci Fi Channel wants NASA to come clean about the existence of UFOs in the U.S. According to Reuters, the cable network is part of a group pressuring the federal government to release documents relating to a UFO sighting in Kecksburg, Pa., in 1965. Sci Fi Channel President Bonnie Hammer believes there's tremendous programming material contained in the top-secret documents. "As we grow the channel," she says, "this will become more and more important."
