What the document records
Project BLUE BOOK was established to investigate UFO phenomena and lasted from March 1952 to December 1969. The project recorded 12,618 sightings and categorized them as identified, insufficient data, or unidentified. Identified sightings were further broken down into categories like astronomical objects, balloons, and aircraft.
Type of case
The case is a visual sighting reported by ground or air observers.
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.
