"Hummingbird" Drone a Spy in the Sky
'Nano Hummingbird' Drone Takes Spying to the Sky - This drone gives new meaning to "bird watching."Tech company AeroVironment has announced that the unmanned, "hummingbird–like" aircraft it's been working on since 2006 has achieved its prescribed goals. The Nano Hummingbird, developed for DARPA, the Pentagon's research arm, has both whimsy and espionage potential. Flying via remote control at something like 11 miles per hour, the drone wouldn't be able to keep up with the living and breathing hummingbird. But then, real hummingbirds don't have cameras.
