Colorado Springs Triangle UAP Sightings - October 2023
Two declassified triangle-shaped UAP sightings witnessed by DOD personnel in October 2023, featuring silent triangular objects with anomalous flight characteristics.
Overview
In October 2023, two separate unidentified anomalous phenomena (UAP) incidents occurred over Colorado Springs, Colorado, involving sightings of dark triangular objects with distinctive flight characteristics. These encounters remained unreported in official channels until the Department of War released them as part of the fifth tranche of declassified UAP files on August 7, 2026, under the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE).
First Incident: Dark Translucent Triangle
Around 10:50 PM on an October evening in 2023, a former Department of War employee and his spouse observed a "dark translucent triangle" from their residential porch in Colorado Springs. The witness, familiar with United States Air Force (USAF) aircraft and military hardware through his DOD background, stated with confidence that the object did not correspond to any known conventional aircraft in the U.S. military arsenal.
The triangular object maintained a silent flight profile, traveling at an estimated altitude of approximately 300 feet above ground level. The entire observation window lasted roughly four seconds before the object departed the visible area. The witness noted the object's lack of visible propulsion mechanism and its completely silent operation—a characteristic notably absent from conventional aircraft at such low altitudes and presumed speeds.
Second Incident: Illuminated Triangle with Corner Lights
During the same month, occurring between 8:00 PM and 9:30 PM, another witness in Colorado Springs observed a distinctly different triangular UAP. This object was described as a "solid black triangular shaped object" with "a red light in each of the three corners," giving it a distinctive appearance unlike conventional aircraft lighting configurations.
The defining characteristic of this second incident was the object's apparent acceleration and maneuverability. The witness estimated the craft achieved speeds consistent with Mach 1 to Mach 2 (approximately 660 to 1,320 miles per hour), with the object performing slight rotational movements. Notably, the witness described the object as appearing "pixelated" or "distorted," suggesting either visual distortion effects, instrumentation artifacts, or unconventional surface properties that created this visual anomaly. Waves of energy or radiation were reported to radiate outward from the object during or immediately before its rapid acceleration phase.
Official Classification and Response
Both incidents were initially unreported in mainstream military or intelligence channels. The Department of War's official assessment, as documented in the declassified files, states that the government was "unable to make a definitive determination on the nature of the observed phenomena." This classification reflects the department's acknowledgment that conventional explanations—such as misidentification of known aircraft, weather balloons, or other conventional objects—could not adequately account for the reported characteristics.
The incidents were formally categorized as unresolved cases and included in the comprehensive August 2026 disclosure release. This release contained 41 documents, videos, and related materials covering UAP sightings from across the United States in 2026 and earlier declassified cases, with records originating from the Pentagon, Federal Bureau of Investigation (FBI), Central Intelligence Agency (CIA), State Department, and Executive Office of the President.
Significance in the Disclosure Era
The Colorado Springs incidents exemplify a pattern increasingly evident in post-2017 disclosure-era releases: credible sightings by military or government-affiliated observers that remain officially unresolved. Unlike speculation-heavy civilian accounts, these witnesses brought technical expertise and access to classified briefings, positioning them to recognize the anomalous nature of the phenomena they encountered.
The presence of these sightings in official government files—rather than relegated to UFO folklore or fringe discussions—underscores the shift in institutional acknowledgment that the UAP phenomenon represents a legitimate subject of scientific and military interest. The August 2026 PURSUE release, of which these Colorado Springs incidents formed a part, further accelerated public access to previously compartmentalized UAP reports.
Credibility Assessment
Both incidents rank among the better-evidenced contemporary sightings, backed by credible witnesses (including DOD personnel) and inclusion in official declassified government records. The lack of conventional explanation, combined with the witnesses' technical backgrounds and the absence of obvious misidentification factors, supports the classification of these incidents as genuinely anomalous. However, like most UAP cases, the incidents remain ultimately unresolved regarding the true nature or origin of the observed phenomena.
