Are UAVs legal in the United States?
Under certain conditions, they are. There are two ways to legally fly Unmanned Aerial Vehicles in the “National Airspace”, which is to say all but certain restricted areas: 1) Get a Certificate of Authorization (COA) or Experimental Airworthyness Certificate (EAC) from the FAA, a process that can take months or more. 2) Fly under exemptions granted to non-commercial (“recreational”) flyers who adhere to certain restrictions. More detail is here.
