Official description

This image is an artistic interpretation of a reported incident near Colorado Springs, Colorado, potentially involving unidentified anomalous phenomena (UAP) in October 2023. This image is based upon a first-hand description provided by a former Department of War employee, as described in FBI-UAP-D026. The Federal Bureau of Investigation prepared this digital rendering in 2026 as a visual aid in support of the PURSUE initiative.

✦ AI visual analysis

Five-page PDF containing a sequence of digital renderings rather than a text document; none of the pages carries a text layer. All five frames share one fixed viewpoint: a suburban back garden at night, seen from behind two silhouetted figures standing side by side on the lawn. A wooden slat fence encloses the garden, two-storey houses stand beyond it, and the sky fades from deep blue overhead to a warm orange band of light pollution along the rooftops, with faint stars visible. The frames differ only in the object depicted in the sky. In the opening frame a faint pale edge is barely visible at the upper right. In the middle frames a pale, semi-transparent triangular form hangs above the rooftops, its surface broken into horizontal bands so that the sky shows through it — rendered as translucent rather than solid, matching the case title. In the final frame the same form appears much narrower and closer to the roofline, seen nearly edge-on as a thin vertical sliver with a triangular profile, reading as the object having rotated or turned away. No text, caption, timestamp, scale or watermark appears on any page. The images are an artistic reconstruction based on a witness account, not sensor imagery.
