Fairy-Tale-Inspired 'Gremlin Drones' Could Spy in Swarms

The Defense Advanced Research Projects Agency (DARPA), which is responsible for developing new technologies for the military, recently announced its "gremlin" program, a drone design initiative. The program is named for the "imaginary, mischievous imps that became the good luck charms of many British pilots during World War II," DARPA said. Like their make-believe counterparts, DARPA's mechanical gremlins will reside inside of manned aircraft.
