What the file records

A bureau bulletin announced the discontinuation of FBI investigations into flying discs. The bulletin was issued following a determination that these objects were likely man-made missiles, not an unexplained phenomenon. The USSR was also reported to be experimenting with similar technology.

Status of the case

The page-level assessment recorded in the file is: discounted by investigators. 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.
