AeroVironment's MicroAir Vehicle looks like a flying laptop with a propeller and is about the same size but carries a digital camera and can fly for nearly two hours. A slightly larger model is the Organic Air Vehicle, which uses a strong fan to keep itself aloft and can hover in place. In DARPA's vision of the future battlefield, unmanned aircraft like these will swarm the skies, providing ubiquitous surveillance for commanders.
