Hackensack, New Jersey UFO Sighting (August 3, 1947) — FBI Files
A first saucer wave case from Hackensack, New Jersey. On August 3, 1947, Charles Casella Jr.
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 August 3, 1947, Charles Casella Jr. and William Truex observed a fast-moving, round black object while waiting to meet Truex’s girlfriend in Hackensack, New Jersey. The object was estimated to be 30-40 inches in diameter and traveling at a high speed approximately 200 yards above the surrounding terrain. A nearby man also noticed the object and appeared excited.
The number of witnesses is not specified in the released document.
Verbatim from the file
“‘RUEX’s girlfriend came out about fifteen seconds after they first sighted it.’”. “‘It faded out of sight shortly thereafter.’”. “‘CASELLA said that this man seemed excited but did nothing about it.’”
Type of case
The case is a visual sighting reported by ground or air observers.
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.
