Global Hawk - and only Global Hawk - has a blanket authorization to fly
in the national airspace. They figure they're launching in a
restricted area and climbing to 60,000 feet, and there's not much
civilian traffic up there


The predators are flying the border, at least, and are under notam. Not a blanket clearance, but there are 100% more of
them this year than last year...
