In September 2023, multiple credentialed witnesses at a U.S. government test site in the western United States reported observing an ellipsoid bronze metallic object, between 130 and 195 feet in length, that materialized out of a bright light in the sky, hung in place, and then disappeared instantaneously. The FBI Lab subsequently produced a composite sketch — released for the first time in PURSUE Release 01 — that overlays a graphic rendering on the actual site photograph based on corroborating eyewitness statements.

The FBI 302 interview included in this release (Serial 5, redacted) captures a first-person U.S.-person account: the subject describes a 'bright light over the horizon' from which the object emerged.

These FBI records are released alongside the AARO Western US Event summary (see related event). Together they constitute the most narratively striking modern case in PURSUE Release 01.
