Project Blue Book's Forgotten Colorado Springs UFO Files
Before 2026's declassified UAP videos, the Air Force logged its own Colorado Springs sightings in Project Blue Book. Here's what those Cold War files reveal.
A Familiar Sky Over Colorado Springs
In August 2026, Denver7 reported that a fresh batch of newly declassified government files included UFO sightings recorded above Colorado Springs. Days earlier, the Colorado Springs Gazette detailed two more declassified UAP incidents tied to the same skies, and back in June, FOX21 News Colorado had already introduced Coloradans to what’s now been nicknamed the “potato” UAP — an oddly shaped object captured on Pentagon sensor footage over the city. Add to that a CIA website posting describing a “frightening” UFO encounter in Colorado, and a New York Post report that pushed the Department of War to open an inquiry into mysterious triangle-shaped UFO videos, and it’s easy to think Colorado Springs has suddenly become ground zero for a new UFO age.
It hasn’t. Colorado Springs has been on the government’s UFO radar — literally and figuratively — since the early days of the Cold War. Long before “UAP” replaced “UFO” in official vocabulary, and long before sensor pods and multispectral video existed to record anything, the U.S. Air Force was already writing down what people over Colorado Springs claimed to see in the sky. The agency doing the writing was Project Blue Book, and its files are sitting in the National Archives right now, available for anyone willing to dig.
The Original UFO File: Project Blue Book
Project Blue Book was the U.S. Air Force’s official UFO investigation program, running from 1952 to 1969. It was the third and longest-lived of the Air Force’s UFO study efforts, following the earlier Project Sign and Project Grudge. Over its seventeen years of operation, Blue Book compiled more than 12,000 reported sightings from across the country, evaluating each one and sorting it into categories — identified as aircraft, balloons, astronomical phenomena, hoaxes, or, in a small but persistent fraction of cases, “unidentified.”
The program was shut down in December 1969, largely on the strength of the Condon Report, a University of Colorado–led study (commissioned by the Air Force and based right here in Boulder) that concluded further study of UFOs was unlikely to yield scientific value. That conclusion effectively ended official federal UFO investigation for decades — until the Pentagon quietly resumed the practice under new names and new acronyms in the 2010s and 2020s, culminating in today’s UAP (Unidentified Anomalous Phenomena) task forces and the declassification wave now making headlines.
Blue Book’s records — case files, correspondence, and investigator notes — are public. They’re held by the National Archives and have been available to researchers for years. Among the tens of thousands of pages are entries logged from towns and military installations across Colorado, including sightings reported in and around Colorado Springs during the height of the Cold War. These weren’t secret in the sense of being hidden from history; they were simply the unglamorous paperwork of a bureaucratic program, filed away and largely forgotten by the public even as the program’s most famous cases entered UFO lore.
Why Colorado Springs, Specifically?
There’s a reason Colorado Springs shows up again and again in America’s UFO record, and it has less to do with anything otherworldly than with geography and military infrastructure. The city sits in the shadow of Cheyenne Mountain, home to NORAD’s underground command complex since the 1960s, and it hosts Peterson Space Force Base and Schriever Space Force Base — installations dense with radar, satellite tracking, and airspace monitoring capability. Wherever the military watches the sky most closely, it also generates the most paperwork about things it can’t immediately explain. Dense radar coverage picks up more anomalies; trained personnel file more reports; classified programs and experimental aircraft (which have historically accounted for a real percentage of “UFO” sightings) get tested nearby. NORAD’s proximity has been a recurring thread throughout Colorado’s UFO history, not because the mountain hides secrets so much as because it comes equipped with the sensors to notice things other places wouldn’t.
That same infrastructure logic almost certainly explains why 2026’s declassified material — the “potato” UAP footage, the triangle videos now under Department of War review — keeps circling back to Colorado Springs airspace. It’s not a new hotspot. It’s the same hotspot, using better instruments.
What’s Actually Different Now
The honest answer is: the evidence itself. Blue Book’s Colorado Springs-era files are largely paper — typed witness statements, investigator summaries, occasional photographs of questionable clarity. They reflect the observational limits of their time: a farmer, a pilot, or an Air Force sentry looking up and describing what they saw, filtered through a Cold War bureaucracy trained to find conventional explanations first.
The 2026 releases are a different animal. According to the recent reporting, the Pentagon’s newer disclosures include actual sensor and video data — the kind of footage that lets investigators (and now, the public) examine flight characteristics, not just secondhand description. The “potato” UAP image reported by FOX21 and Nonstop Local News, and the triangle videos now being investigated by the Department of War following the Post’s report, represent a qualitative shift: multispectral and infrared capture instead of a witness’s memory written down by an officer weeks later.
What hasn’t changed is the fundamental problem. Then and now, “unidentified” doesn’t mean “extraterrestrial” — it means the available evidence hasn’t been matched to a known cause yet. Blue Book closed roughly 94% of its cases with conventional explanations and left the rest genuinely unresolved, not because investigators believed in aliens, but because the data ran out. The 2026 files carry the same open-ended quality: better resolution, better sensors, and still — for now — objects that resist easy categorization.
The Continuity Nobody’s Talking About
The current news cycle treats this year’s declassifications as a revelation, and in terms of the specific footage, they are. But the underlying story is one of continuity, not novelty. Colorado Springs has been quietly generating UFO paperwork for over seventy years, filed under acronyms that have changed even as the airspace and the questions have not. The Cold War-era investigators who typed up Blue Book reports on manila folders and the Pentagon analysts studying sensor footage of a potato-shaped object share the same unfinished business: a small, stubborn category of sightings over Colorado Springs that nobody — then or now — has been able to fully explain.
For those curious enough to look past the headlines, the National Archives’ Blue Book records remain open to the public, a paper trail leading straight back from this summer’s viral disclosures into the mountain’s long, quiet history of being watched — and of watching back.
