New Unmanned Aerial Vehicle Designs
Aurora GoldenEye 80 Hovercraft is a vertical takeoff and landing (VTOL) tactical unmanned aerial vehicle. The duct fanned vehicle is very loud and would need to be a long distance from the enemy to avoid detection.
British Taranis UCAV is currently undergoing wind tunnel testing. It will not be flight tested until 2010. This craft is considered to be a "low observable" (stealthy) craft and is therefore difficult to detect.
Note: The above craft obviously are of strange design and would likely generate a number of UFO reports when tested. They are displayed only to show readers that unusual unmanned aircraft are being flown and many more are undergoing design and testing.
