US working on rules for flying drones over populated areas

According to documents seen by AP, the committee has divided drones into four separate categories for flights over people. The first includes drones under a half-pound with no flight restrictions. However, the manufacturer would have to certify that there would be no more than one percent chance of a person being hurt if it fell on them. The second category is for the most common type of recreational and commercial models by the likes of DJI (above), 3D Robotics and others. Those range from four to five pounds in size, though there would be no set weight limit, according to the AP.
