The Vikings were the most ferocious warriors of the Middle Ages. Especially fearsome were the select few who wielded a formidable weapon: a light, razor sharp, virtually indestructible sword with its maker's name, Ulfberht, inlaid along the blade.

The Rise of Drones

Peter Yost, Peter Yost

Drones. These unmanned flying robots–some as large as jumbo jets, others as small as birds–do things straight out of science fiction. Much of what it takes to get these robotic airplanes to fly, sense, and kill has remained secret. But now, with rare access to drone engineers and those who fly them for the U.S. military, NOVA reveals the amazing technologies that make drones so powerful as we see how a remotely-piloted drone strike looks and feels from inside the command center. From cameras that can capture every detail of an entire city at a glance to swarming robots that can make decisions on their own to giant air frames that can stay aloft for days on end, drones are changing our relationship to war, surveillance, and each other. And it's just the beginning. Discover the cutting edge technologies that are propelling us toward a new chapter in aviation history as NOVA gets ready for "Rise of the Drones."
