A first saucer wave case from Hackensack, New Jersey. On the evening of August 3rd, 1947, witnesses observed a round, silver-blue object in the sky.
Background
On August 3, 1947, in Hackensack, New Jersey, U.S. government investigators recorded an unidentified-object incident later released to the public on May 8, 2026 as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). The incident is one of the first wave of “flying saucer” reports that swept the United States after the Kenneth Arnold sighting of June 1947 and the Roswell incident of July 1947. The case was filed with the Federal Bureau of Investigation, whose Knoxville, Albuquerque, Los Angeles, and other field offices routed UFO reports to headquarters under the Bureau’s standing protocols for the protection of vital installations.
What the document records
On the evening of August 3rd, 1947, witnesses observed a round, silver-blue object in the sky. The object appeared to be revolving and was visible for approximately one minute before disappearing over the horizon. Witnesses estimated the object to be small at a distance, but potentially larger if closer.
The number of witnesses is not specified in the released document.
Verbatim from the file

Type of case

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.
