This Mission Report (MISREP) documents a U.S. military operator's observation of an object that resembled a balloon, reportedly drifting with the winds at around 31,000 feet. The object was visually tracked using an onboard infrared sensor.
This document is a Mission Report (MISREP), a standardized form the U.S. military uses to record the circumstances of its operations. Such reports are commonly used to relay Unidentified Anomalous Phenomena (UAP) observations to the All-domain Anomaly Resolution Office (AARO), with the general-text (GENTEXT) section providing qualitative, contextual information.
The report states that a U.S. military operator observed a UAP that "look[ed] like a balloon," reportedly "traveling with the winds at approximately 31,000 ft." The object was visually tracked using an onboard infrared sensor. All descriptive and estimative language reflects the reporter's subjective interpretation at the time and should not be read as a conclusive determination of any object features or performance.
The record was released to the public through the PURSUE declassification by the Department of War.
