Observer Uh Dt, Robart UAP Encounter, 1947 — USAAF Box 7 #111
An archived U.S. Army Air Forces report from 1947 documents an unidentified flying object sighting near Observer Uh Dt, Robart.
Historical Context of the 1947 Phenomenon
The year 1947 represents a pivotal moment in the history of aerial anomaly documentation. Following the conclusion of World War II, the United States entered a period of intense technological transition, characterized by the emergence of jet propulsion and the early stages of the Cold War. During this era, the sudden appearance of unidentified aerial phenomena, often colloquially termed “flying saucers,” began to saturate news media and military reporting. This specific period is frequently identified by historians as the first “saucer wave,” a phenomenon triggered by high-profile sightings that captured both public imagination and military scrutiny.
The cultural and technological landscape of the late 1940s provided a unique backdrop for such reports. The rapid advancement of aerospace engineering meant that the sky was increasingly occupied by experimental craft, while the public was simultaneously processing the unprecedented scale of aerial warfare experienced only years prior. This heightened state of vigilance contributed to a surge in reported sightings that were often difficult to categorize using the contemporary scientific frameworks of the time.
The Robart Incident Documentation
In 1947, near Observer Uh Dt, Robart, the U.S. Army Air Forces recorded an unidentified-object incident that became Incident #111 in the “Check-List - Unidentified Flying Objects” series archived in Box 7 of file 38_143685. The specific details of the encounter were preserved within military archives and were later released to the public by the Department of War on May 8, 2026, as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE).
The primary documentation for this case is found within the official U.S. Army Air Forces “Check-List - Unidentified Flying Objects” series. The summary records that an unspecified observer reported a sighting near Observer Uh Dt, Robart. As a visual sighting reported by ground or air observers, the case falls into the fundamental category of optical aerial anomalies. While the specific characteristics of the object’s flight path or luminosity are not detailed in the summary, the existence of the report itself confirms that the event was significant enough to be formally logged into the military’s tracking system during the height of the 1947 saucer wave.
Classification and Investigative Status
The classification of Incident #111 is consistent with other visual sightings from the mid-century era. It is positioned chronologically alongside other landmark events, such as the Kenneth Arnold sighting of June 1947 and the Roswell incident of July 1947. These events collectively shaped the trajectory of aerial anomaly investigation for decades.
Under the current regulatory framework, all records released under the PURSUE program are designated as unresolved by the All-domain Anomaly Resolution Office. The federal government maintains a neutral stance regarding the nature of the Robart encounter. The authorities have not concluded that these 1947-era incidents were anomalous, nor have they concluded they were conventional; the possibility of either remains open.
When evaluating the origins of such 1947-era sightings, investigators often consider several conventional candidates. During this period, the United States Southwest was the site of active Project Mogul balloon flights, which utilized high-altitude sensors to detect Soviet nuclear tests. Additionally, the era saw the testing of experimental jet and rocket aircraft, as well as various atmospheric optical effects and astronomical objects that could be misidentified at unusual angles. The Robart case remains a subject of study within this broader context of unidentified aerial phenomena.
