Numerous unidentified objects, possibly drones, have been spotted loitering over military bases, water infrastructure, and restricted airspaces. The majority of reports are in NJ, but several accounts are coming in from Phoenix AZ, UK, Germany, and Brazil. The only firm stance the government has taken is that they are not nefarious and do not pose a threat.
Mayors, Sherifs, Governors, FBI, DHS, Coast Guard, and DOD have stated that they are not responsible for all of the objects in the sightings.
This recent wave started just before Thanksgiving I believe.
