Unknown Drone 12-11-11: My sister and her boyfriend were heading back to Arkansas City KS coming from the gas station-casino on or near the Oklahoma state line, when they noticed the object being towed. A state trooper escorted it and black truck followed. Could it be an unmanned US drone?

Looks like an X-47B with the wings removed.
