I could be remembering wrong, but I believe the last time I checked, the FAA required people operating RC planes/quadcopters to maintain a physical line of sight to their machine, with the implication being you need to do so to remain in control of the machine. A quadcopter a mile away is definitely outside controllable line of sight, and this guy should be getting questioned by the FAA.
