Unmanned aerial vehicles, "drones" or "UAVs" for short, are getting to be pretty impressive affairs. Target-tracking software allows one drone to fly by its own wits, even above 15,000 feet. Overseen by humans, these planes can chase down a moving vehicle, send reports to a human operator by cell phone, collect photo images and video, and even relay information via VoIP.

Even with the new autonomous capabilities in the ScanEagle, surveillance efforts will often dictate that a human maintain a greater degree of oversight. One major objective of these flyers is to reduce the risk to human scouts in dangerous areas. Check out the amazing technology involved in keeping troops informed.
