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

News to me, but OK.

The predator hat crashed was operating in the low teens, when it went
haywire, and went down, right through an area that was not notamed, as far
as I know.

Fortunately, the "big sky" theory worked, and nobody else got mid-air'ed.
