AARO Unresolved Case Analysis Update: Western United States Event
A two-day UAP incident near a sensitive national security site in the western U.S. gets the AARO treatment here — and three years later, the office still doesn't have an answer. The memo documents the state of ongoing analysis, making it a rare look at an active unresolved case rather than a post-hoc summary of something explained away.
This memorandum summarizes the All-domain Anomaly Resolution Office’s (AARO) ongoing analysis of a reported incident near a sensitive national security site in the western United States involving unidentified anomalous phenomena (UAP) over a period of two days in 2023. As of June 2026, the case remains unresolved.
