From New York Post:
A New Jersey mayor warned Tuesday that the troubling drone sightings over the state may be linked to missing radioactive material, although federal officials say the amount poses no serious threat either way.
Belleville Mayor Michael Melham said the drones flying in a grid-like pattern over his Essex County township appear to be “looking for something. “What might they be looking for? Maybe that’s radioactive material,” Melham told Fox TV’s “Good Day New York.” “It was a shipment. It arrived at its destination. The container was damaged, and it was empty,” Melham said.
