Aircraft without pilots are currently banned from U.S. airspace, but the ban only applies to high-flying "real" drone aircraft, not personal, toy-sized fliers like the quad-rotor in the video, versions of which are sold in electronics and hobby stores.
Drones in U.S. skies may threaten more than just privacy
The FAA is in the middle of a $64 billion upgrade to the national air-traffic control system that will allow it to track more and smaller aircraft, including drones, in time to comply with new rules passed by Congress requiring that drones be allowed to fly in the U.S. by Sept. 30, 2015.
Most of those demanding to use drones in the U.S. now are police or security agencies looking for eyes in the sky, help monitoring long borders and other observation missions.
That's the role drones started with in the U.S. military, too.
It didn't take long for them to grow up and start carrying guns, though, weapons that went from taking out the occasional target of opportunity to being a primary weapon in the Obama administration's campaign to eliminate terrorist leaders in Afghanistan and Pakistan.
The Electronic Frontier Foundation and other privacy-protection groups are lobbying for rules that would keep drones from being used in ways that invade the privacy of people on the ground, especially if they're cheap and easy enough for private organizations or individuals to buy and fly.
