LIBERAL, Kan. A father and son have an extraterrestrial explanation for the strange rock that recently landed in their back yard in southwest Kansas. They are convinced it's a meteorite.

Chandler Harp, 10, was playing in the back yard of his home when he heard what sounded like an explosion about 15 feet from where he was standing. He looked over to see a plume of dirt and debris shoot 5 feet high.

At the bottom of a foot-deep hole, he found a 2-inch rock and showed it to his dad, Lee.

Once Lee Harp got a look at the metallic rock, he was certain it wasn't from this world. He said, "I knew he had a meteorite."
