Mysterious drone sightings in New Jersey raise questions about regulations. Here are 5 things to know

Recently, sightings of what appear to be drones flying over New Jersey at night have created anxiety among some residents.

Drones for commercial and recreational use have grown rapidly in popularity, despite restrictions on who can operate them and where they can be flown.

No-fly zones are enforced around airports, military installations, nuclear plants, certain landmarks including the Statue of Liberty, and sports stadiums during games.

Not everybody follows the rules. Sightings at airports have shut down flights in a few instances.

Reported sightings of what appear to be drones flying over New Jersey at night in recent weeks have created anxiety among some residents, in part because it is not clear who is operating them or why. Some state and local officials have called for stricter rules to govern drones.

After receiving reports of drone activity last month near Morris County, New Jersey, the Federal Aviation Administration issued temporary bans on drone flights over a golf course in Bedminster, New Jersey, that is owned by President-elect Donald Trump, and over Picatinny Arsenal Military Base. The FAA says the bans are in response to requests from “federal security partners.”
