The incident is a Cold War-era case investigated under the Air Force’s Project Blue Book or its predecessors.

He had initially contacted them on June 1st, but received no response. The Bureau of Aeronautics and Naval Intelligence ultimately decided not to pursue the matter due to a lack of concrete evidence.
The number of witnesses is not specified in the released document.

Status
All records released under the PURSUE program are designated unresolved by the All-domain Anomaly Resolution Office (AARO) by default. The federal government has not concluded that the events were anomalous, has not concluded that 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 in the late 1940s), atmospheric optical phenomena such as sundogs and lenticular clouds, and astronomical objects including Venus, the Moon, and meteors near the horizon.
