From the source: Release of 2026-05-08 Incident: 9/16/20, Strait of Hormuz. Released with redactions. This document is a Mission Report (MISREP), a standardized reporting form the U.S. Military uses to record the circumstances surrounding its operations. U.S. military services often use MISREPs to report Unidentified Anomalous Phenomena (UAP) to AARO. The GENTEXT, or “general text” section of these reports often contains important qualitative, contextual information, distinguishing it from the more quantitative, or numerical, data found elsewhere in the report. A U.S. military operator reported observing one UAP at an estimated altitude of 1,800 feet. All descriptive and estimative language contained in this report reflects the reporter’s subjective interpretation at the time of the event. Such characterizations should not be interpreted as a conclusive indication of the presence or absence of any intrinsic object features or performance characteristics.
