A chap called William E Burrows wrote a book called "Deep Black" about the development of US spy satellites, esp. the Keyhole series (think Hubble, but pointing down).

There is also some fascinating info in his book "This New Ocean", a history of space flight and exploration. The NRO's spy satellites are operated from the Satellite Control facility, a windowless building called the "Big Blue Cube" in Sunnyvale, California.

Perhaps some CA freeper could drive by and take some photos :-) On second thoughts, maybe we should stick to these:

That's the one I was thinking about, just didn't remember the exact title and author. I read it some time ago.

I certainly hope they have not one, but several other such facilities deep underground somewhere, this one looks too exposed and vulnerable.
