About the Show
NOVA: A provocative investigation into the growth of airborne UAVs, or pilotless drones. During the invasion of Iraq in 2003, the United States deployed only a handful. Now, the US has more than 7,000 drones and over 40 other nations are building or buying these lethal and cost-effective weapons. This new ability has already saved the lives of hundreds, if not thousands, of US service personnel but may make military strikes a more tempting and seemingly risk-free option.
