Status

AARO designates unresolved cases as those for which the agency has not concluded the events were anomalous, has not concluded that they were conventional, and has not ruled out either possibility. Conventional candidates for sightings of recent periods include commercial drones, classified test platforms, satellite re-entry, balloon traffic, atmospheric optical phenomena, and astronomical objects.
