DO NOT PANIC! Its completely human made! The XR-23 is the United States Airforce latest achievments in Saucer technology. Called the Flying Saucer or eventually nick named the "Duck" because of it's odd ability to float on water. That right folks, this is a land, air and sea tacticle fighter and long range bomber. Don't worry, if you happen to see this flying arround, we wont call it a weather balloon!
