- **Sightings**: Since mid-November, numerous reports have surfaced about unidentified drones appearing at night in several New Jersey counties and later in New York, Pennsylvania, and other states[1][2].
- **Investigations**: The DHS has stated that after examining technical data and tips from concerned citizens, their assessment is that most sightings can be attributed to lawful commercial drones, hobbyist drones, and law enforcement drones, as well as manned fixed-wing aircraft, helicopters, and stars mistakenly reported as drones[1].
- **Concerns**: Local law enforcement officials have expressed concerns about the potential "nefarious" nature of some drones, but federal investigators have not found any evidence that the drone sightings pose a national security or public safety risk[1][5].
- **Proposed Explanations**: Various theories have been suggested, including the possibility of the U.S. military testing new systems (which some officials have discounted) and foreign countries being the source of the sightings (claims that federal investigators have repeatedly rejected)[1][3][5].
