Langley, Virginia. CIA HQ. The heart of U.S. ForInt acquisition and processing. An obvious highest priority target for enemy action, and a place, like its counterparts, rife with paranoia and security - in almost equal, momentarily fluctuating, proportion.
The airspace for tens of miles around is a no-warning no-fly zone, of course. Those shot down have zero legal recourse- ditto their next of kin.
