It begins at night—always at night. Residents across New Jersey have been witnessing something straight out of science fiction: vehicle-sized drones flying low over neighborhoods, their navigational lights flashing like signals in the darkness. At first, people thought they were planes, maybe helicopters. But these machines don't behave like either. They hover, stop mid-flight, and dart sideways with precision before rocketing into the sky at unimaginable speeds.

"It's kind of unsettling," said Mike Walsh, a Randolph resident who has seen the drones numerous times. "Some are very big, probably the size of a car." (Source: Yahoo News)
