Signs of the drone times

"DJI, the company that manufactured the drone that crashed at the White House, announced in March that its new geofencing software would make its devices inoperable within roughly 16 miles of the White House. The company said it was working to create similar no-fly zones for “sensitive institutions and national borders.”

An organization called No Fly Zone has introduced a website where individuals, business owners and others who do not want drones overhead can enter their addresses into a database. Those addresses will be provided to drone manufacturers who have agreed to program their devices not to fly over those locations."
