On October 21, 1978, 20-year-old Australian pilot Frederick Valentich rented a single engine Cessna 182L and left Melbourne, Australia to begin a 48-mile training flight. During the flight, Valentich told Melbourne air traffic control that an aircraft about 1,000 feet above him was accompanying him. He said, "The strange aircraft is hovering on top of me again. It is hovering and it's not an aircraft." Frederick Valentich and his plane were never seen again. Texas Blue Dogs- Since 2004 bizarre hairless, blue-skinned, blue-eyed and hunch-backed dogs have been seen in Texas attacking and mutilating livestock and farm animals. The creatures have been caught on film and camera, and their bodies have been found. One Texas doctor even has one stuffed and mounted in her fireplace. But the classification of these creatures is still very much a matter of great debate among experts.
