We may have a hint as to where one of those UFOs that was shot down came from. A group of amateur balloonists based in Illinois says one of its small balloons is "missing in action" after reporting its last location over Alaska on Saturday. That's the same day a U.S. fighter jet shot down an unidentified object in the same area. The Northern Illinois Bottlecap Balloon Brigade hasn't blamed the government for taking out one of its 32-inch-wide balloons. In a post on its blog, the club noted that the balloon's last transmission near a small island off the west coast of Alaska was made after the balloon had been airborne for more than four months and circled the globe seven times.
