In April 2026, a retired US Air Force radar maintenance technician reported a remarkable radar contact from spring 1967 at Fortuna Air Force Station (AFS) in North Dakota. The individual, who was part of the 780th Radar Squadron, described tracking an object travelling at approximately 5,000 mph on the AN/FPS-35 search radar and his attempts to lock the target on the height finder radar (AN/FPS-26) were unsuccessful due to the object's speed. The incident occurred during his service at Fortuna AFS between October 1966 and December 1967, with the event taking place during early morning hours while off duty and playing cards with fellow radar staff. Shortly thereafter, personnel were visited and interrogated by Air Force Office of Special Investigations (AFOSI), who emphasised secrecy regarding the sighting. This report was submitted to NUFORC and thoroughly investigated by a seasoned UFO researcher, who verified its credibility and linked it to other contemporaneous UFO-related incidences reported at nearby missile bases.
Key details reveal the object’s radar signature was highly anomalous; unlike conventional aircraft that move smoothly across radar sweeps, the contact jumped intermittently as the radar dish rotated every 12 seconds. Communication with other bases, including Minot AFB and Opheim AFS, confirmed the object's fast north-northwest trajectory. The radar operators nicknamed the regular scope monitors “scope dopes,” and it was one such operator who first noticed the unidentified target, prompting the immediate inquiry. The AFOSI team's arrival the following day and their apparent pressure to suppress discussion is suggestive of official concern. Cross-referenced archival files also record significant UFO incidents involving Minuteman missile silos at Minot (5 March 1967) and Malmstrom AFB (16 March 1967), corroborating a broader pattern of UFO encounters coinciding with sensitive nuclear missile sites. This incident adds to the body of evidence illustrating a high level of mystery and potential threat during the height of the Cold War nuclear deterrence era.
The Fortuna AFS radar incident forms part of a well-documented phenomenon observed in the 1960s Cold War environment whereby unidentified aerial phenomena appeared in proximity to critical nuclear missile infrastructure. Known as "nuclear missile interference" cases, these events involved UFOs tracked by sophisticated radar systems and coincided with unexplained disruptions or shutdowns of missile systems at strategic bases. Such incidents prompted secretive investigations and non-disclosure attempts by military and intelligence agencies, underscoring perceived national security implications. The network of radars within the Semi-Automated Ground Environment (SAGE) system was designed to detect hostile Soviet bombers, yet these encounters challenged conventional aerospace threat paradigms. The extraordinary speeds, radar behaviour, and repeated targeting of nuclear assets differentiate these reports from typical unidentified lights or aircraft and have been the focus of considerable scrutiny within UFO research circles and official investigations. This Fortuna case is notable for its corroboration by a credible witness and the suppression efforts, reinforcing ongoing questions about Cold War UFO events and their implications for understanding the intersection of UFO phenomena and national defence.
