A satellite image taken by Google Earth related to a mysterious vehicle, apparently an unmanned aerial vehicle (UAV), parked at Lockheed Martins Skunk Works facility in Palmdale, California. The dimensions calculable from the image suggest that the photographed aircraft match the one ones for wingspan of the secretive RQ-170 Sentinel. The drone was sighted for the first time in Kandahar Air Field in 2007, later the Air Force confessed to use it for surveillance operations. A similar drone was captured by Iranian forces near the Iran-Afghanistan border in December.”]
