Worried yet by the first landing of an unmanned Navy drone on an aircraft carrier, thus rendering possible combat "anywhere on the planet"? If not, try this: First video on DARPA's "next generation of surveillance," the $18.5 million Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System (ARGUS), the most advanced surveillance system in the world, capable of patrolling at 17,500 feet and sending back high-resolution images of 1.8 gigapixels so clear you can see the color of a bad guy's - or good guy's, or your - shirt. Just so you know. And NOVA aired this a few months ago; God knows what they can do now.
