Sorry I read that as 200 meters. I did not know you could operate 200 Kilometer line of sight. I would have thought the curveture of the earth would have caused unrealistic .

However 200 kilometers and line of sight is still somewhat short range for modern UAV's. But the fact that UAV's use 2.4 at that range and there will be even more UAV's when the FAA gets their new regulations in effect, then that supports the article.
