The FAA wants to clip drone wings. Proposed rules would require drones to stay in view of their controllers — meaning no night flights and no long distances. It would also put the kibosh on widely publicized plans by firms like Amazon for using drones for deliveries. Critics say the “in sight” rules could negate most of the usefulness of drones. A public comment period starts now, and it will likely be a couple years before any regulations go into effect.
