I made a joke of the situation before learning of this a/c's fuel capacity.
After reading about 24 hour fighter cover and SAM's around the G8 summit, I can't help to wonder if the pucker factor of the security folks there might be a little high for good reason.
I wouldn't doubt that the defense ring around Evian extends quite a ways. No doubt there has been more than a few briefings about this missing a/c along with photo's of it in the cockpits of armed interceptors.
My bet is still on a repo job though.
