This opens up the need for discussion about how to fly a UAV to theatre from its MOB in blighty. Tricky. The ability to do so however, would present a significant strategic capability.
Could it not fly airways under "normal" ATC control? It seems to me that it makes very little actual difference whether the pilot is sitting in the plane controlling the fly-by wire computers, or is many miles away, providing he is talking to the relevant ATC centre and responds to any instructions given. It's slower speed might be an issue though.
