Status of the case

The page-level assessment recorded in the file is: no agency assessment. All records released under the PURSUE program are designated unresolved by the All-domain Anomaly Resolution Office unless otherwise stated, meaning the federal government has not concluded the events were anomalous, has not concluded they were conventional, and has not ruled out either possibility. Conventional candidates for sightings of this period include experimental aircraft, weather balloons (especially the Project Mogul series), atmospheric optical phenomena, and astronomical objects.
