In recent weeks there have been numerous reports of mysterious drones flying over parts of New Jersey and the U.S. East Coast. New Jersey Governor Phil Murphy, the White House, U.S. President-elect Donald Trump and the FBI have all weighed in on the matter, although there remain more questions than answers. Here’s what we know.

Reports of drone sightings over New Jersey started in mid-November. The first sightings were in Morris County in the north of the state, and along the Raritan River, about 80 kilometres west of New York City.
