Drones Over America: What Can They See?

"Unmanned aircraft systems, or drones, have long played a role in military operations. But imagine thousands of drones flying over U.S. skies — something we may see in just a few years. In February, President Obama signed an aviation bill requiring the Federal Aviation Administration to make plans to integrate drones into American airspace."

"On Monday's Fresh Air, John Villasenor, a senior fellow at the Brookings Institution and a professor of electrical engineering at UCLA, explains what these drones will be able to see and how they work. He also talks about the privacy and national security concerns raised by using drones for surveillance purposes."
