The Otero accident was a failure documented by the United States government at the Advanced Particle Physics Laboratory (APPL), located within Otero County, Colorado. According to various individual sources, the accident occurred at 10:22 a.m. on October 13, 1960. Despite the APPL having an on-site dedicated nuclear power facility, the event was so demanding to the greater linked energy system that it nevertheless collapsed the power grid of the Southern Colorado Power Company’s service area and triggered widespread incidents across multiple states in the process.
Following the accident, custody of the facility—previously under the purview of the Atomic Energy Commission (AEC)—was transferred to the Department of Defense. The site has since been operated under the new name Defense Energy Research Center (DERC).
The full details of the APPL accident remain classified by the federal government. Rumors have persisted since the early 1960s that the accident involved experimentation with particle acceleration. Purported whistleblowers, such as physicist John Haynes, have claimed the event may have resulted in the creation of a physical singularity, describing it as “perhaps the greatest error in the history of mankind.” According to Haynes, under different variable conditions, the singularity could have expanded into a black hole. These claims, however, remain unsubstantiated. In 2012, the U.S. government referred to the accident as “merely electrical in nature”—the only official statement made about the event.
Background
Details regarding the Otero accident remain murky, with most available information originating from anonymous whistleblowers or individuals using pseudonyms. The only confirmed whistleblower with verified credentials linking him to the event was John Haynes, who worked as a nuclear physicist under the Atomic Energy Commission.
The AEC, operating under federal directives, had been tasked with experimentation on “the nature of particle physics,” as authorized by the Atomic Energy Act of 1946 (also known as the McMahon Act), signed by President Harry S. Truman. Often referred to as the “Truman Plan” (not to be confused with the Truman Doctrine), the AEC collaborated with other federal research bodies, including elements of the Office of Naval Research. These efforts led to the construction of a specialized research site in the arid plains of Colorado in late 1951, formally designated as the Advanced Particle Physics Laboratory.
According to the AEC, the APPL focused on research into particle interactions as a means of exploring nuclear and quantum phenomena. However, as attested by Haynes, the laboratory's true mission was to investigate the “transition of the quantum back to the macroscopic” using a novel particle accelerator design.
Purported accident and the Otero Harmonic

At 10:22 a.m. MST on October 13, 1960, Colorado experienced the largest power outage in its history. The cause was not attributed to infrastructure failure, but rather to an “unusual and reactive power demand localized to the outskirts of Otero County.” Leaked memos and technical logs from the Southern Colorado Power Company in the 1970s revealed that senior engineers assumed damage from a harmonic excitation event. This phenomenon, which is rare and poorly understood, involves self-reinforcing oscillations in a power grid that escalate into a runaway feedback loop.
According to these impromptu hypotheses, such a resonance must have been triggered by a high-frequency electrical surge in southeastern Colorado, later confirmed to be the APPL. The resonance would have spread throughout the regional grid, causing thermal runaway in transformer cores across Southern Colorado that resulted in burnout or magnetic damage. Substations in western Kansas, northern New Mexico, and the Oklahoma Panhandle reported similar malfunctions, despite no indication of conventional overload. Engineers at the time described voltmeters “fluctuating uncontrollably,” breakers that failed to trip, and frequency meters drifting into uncharted ranges.
According to Haynes’s testimony, the event was internally referred to by federal authorities as “the Otero Harmonic.” Although this term has gained traction in conspiracy theory communities and popular media, it has never been officially used by the U.S. government or a supervisory body. In addition, no physical media depicting this harmonic resonance has become available to the public.
Fabrications, explanations, and incredulity
Some reports regarding the reach of the harmonic event have been proven to be fabricated, especially those from outlying states. These include falsified Texan logbooks that surfaced following Haynes’s death in 1975. The forgeries were presented as evidence for the broader geographic impact of the Otero-originating harmonic resonance.
Harmonic resonance
Experts such as Dr. Jeremy Laney, an electrical engineering professor at the University of Southern California, have raised significant doubts about the plausibility of the so-called “Otero Harmonic” phenomenon. In a 1995 panel on historical grid disturbances, Laney expressed deep skepticism that harmonic resonance alone could account for the scale of the failure attributed to the APPL incident.
According to Laney, for a harmonic resonance event to propagate across multiple states (disabling substations, overloading transformers, and bypassing standard protective relays) would require “the largest short-circuit discharge or nonlinear load ever recorded in the history of electrical infrastructure.” He further noted that even deliberate harmonic injection studies using high-capacity testing facilities have never demonstrated such widespread or cascading impacts.
Laney also pointed out that harmonic resonance typically causes localized equipment failure, not region-wide systemic collapse. “You would need a harmonic source with both enormous power and precise alignment with the resonant frequencies of hundreds of substations operating under different load conditions. The probability of that occurring spontaneously, and without being intentionally engineered, is vanishingly small.”
Critics of the “Otero Harmonic” theory also highlight the lack of contemporaneous technical documentation. No substantiated forensic analysis or independent failure modeling from the 1960 period has ever been released to the public. Furthermore, modern harmonic modeling of 1960s-era grid architecture has failed to replicate the scope of the reported effects, even under extreme nonlinear input scenarios.
Laney and others argue that the invocation of harmonic resonance may have functioned as a “technical placeholder” for a more complex or classified failure mode. “It’s a term that sounds scientific enough to deflect questions,” he said, “but it doesn’t hold up to scrutiny when you compare it with known harmonic behavior in distributed power systems.”
John Haynes
Haynes remains a controversial figure, with critics—both academic and governmental—considering his claim that the APPL created a singularity to be unreliable.
Dr. James T. Mullins, former director of the APPL, delivered a personal statement after Haynes’s death and the resulting media interest in the Otero accident. Mullins acknowledged Haynes’s role in nuclear research at the facility but also noted that Haynes had developed mental health issues following the death of his wife from cancer prior to 1960. Mullins suggested that the combination of personal loss, long work hours, and isolation likely “exacerbated a latent mental illness… that psychologists he visited were yet to fully capture.”
Dr. Kasen Warren of the University of Colorado at Boulder directly criticized many of Haynes’s claims. In a 1981 interview, Warren argued that creating a singularity—particularly one capable of catastrophic growth—was scientifically impossible with any known terrestrial means. He explained that such a phenomenon would require energy densities on the order of the Planck scale (~10¹⁹ GeV), far beyond what any Earth-based accelerator could produce. Warren noted that, “If the idea of a singularity developing at the APPL is to be entertained, we’d see them from cosmic rays hitting Earth’s atmosphere—at much higher energies than we can generate.”
While electromagnetic interference was indeed recorded beyond the facility, Warren and other physicists believe it was likely caused by a more mundane electrical event.

Requested move 1 July 2012
Otero accident → Otero conspiracy theory – The current title implies a sort of factual consensus on the nature of the event. However, the article itself repeatedly states that the event's cause remains classified, and its most significant claims derive from untrustworthy whistleblowers (primarily Haynes) and unverifiable sources. Furthermore, the term “Otero Harmonic” is only used within conspiracy theory circles and has not been officially recognized by a supervisory body. Given the speculative and highly contested nature of the claims—especially the singularity creation theory—the title “Otero conspiracy theory” would better reflect the article's contents and avoid misleading readers. — Nomination by User:Wiredinspectorr
Support
User:Wiredinspectorr – As the nominator, I reiterate that this article’s core subject—the so-called "accident"—lacks confirmation beyond anonymous sources and a single discredited physicist. The tone of the article borders on undue weight for fringe theories. “Conspiracy theory” is more accurate and reflects how this topic is treated in academic and media discourse.
User:DrMechanism42 – Support. The current article conflates an alleged incident with speculative interpretations of that incident. Calling it an “accident” lends the air of factual documentation, but no government document confirms what actually occurred. The fact that the most cited source (Haynes) is widely discredited should be reason enough to frame this as a theory, not a documented event.
User:86echoDelta – Strong support. If anything, the event—assuming it happened at all—has only been referenced in passing by the U.S. government as “electrical.” The leap from that to black hole formation is a textbook conspiracy trajectory. Wikipedia has a responsibility to avoid amplifying pseudoscience by labeling it neutrally. “Conspiracy theory” is not a pejorative here; rather, it is an accurate categorization.
Oppose
User:cloud_rchivist – Oppose. While the claims surrounding the incident are speculative, there is strong evidence that something occurred at APPL on October 13, 1960. Referring to it as a “conspiracy theory” might imply that no event occurred at all, which is not what the article implies. This move risks invalidating the documented power collapse, which is independently verifiable. This is not analogous to, say, moon landing denial.
User:graincst – Oppose. There is a difference between fringe theories about an event and the event itself. The title “Otero accident” refers to the occurrence (or alleged occurrence) at the APPL facility. The article can, and should, include a section on conspiracy theories, but we should avoid titling the entire article as such. We don’t rename “Roswell incident” to “Roswell conspiracy theory” for similar reasons.
User:Criteriumset – Mild oppose. I agree that the article is speculative, but Wikipedia policy is to use the most commonly recognized name. In books, forums, and even scientific critiques, it’s still often referred to as the “Otero accident” or “Otero Harmonic event.” We might consider a compromise—perhaps “Otero incident (conspiracy theory)”?—but the proposed title feels dismissive of a complicated and partially verifiable situation.
Neutral / Comment
User:zapostlight – I suggest a split: one article for the “Otero accident” describing the historical and infrastructural facts (power grid collapse, site handover), and a separate one titled “Otero conspiracy theory” that collects all claims made by Haynes and others. This way, readers and editors can separate fact from speculation without blurring the lines in a single article.
User:ellipticality – It might be worth waiting for more sources to emerge. The 2012 statement from the U.S. government acknowledging “an electrical event” shows that the entire narrative isn’t purely invented. That said, much of the article currently centers on Haynes’s singularity claim, so perhaps restructuring the content is a better first step before renaming.
User:snakeyes88 – I believe renaming the article to Otero conspiracy theory is premature and potentially misleading. While official confirmation is limited, there are numerous independent testimonials, some dating back to the early '80s, indicating that the “accident” may have had deeper implications. A declassified memo I came across in a FOIA archive (no longer online) referenced “gravitational anomalies” near the APPL site within days of the event. That doesn’t sound like a simple power grid overload to me…
Additionally, there have been anomalous magnetic readings recorded in Otero County as recently as 2009, correlating with what Haynes described [see: Magnetometer Readings @ OTERO COLORADO 2009, r/gravitomancy). These are patterns. Until we know more, the term “accident” remains appropriate and neutrally descriptive.
User:CitationBalance – Refrain from citing unverifiable, unreliable, or inaccessible sources (such as removed FOIA documents) unless they can be independently corroborated, please. Assertions about “gravitational anomalies” fall under WP:FRINGE and require support from reputable, peer-reviewed sources, not Reddit. Wikipedia is not a venue for speculative synthesis (see WP:SYN).
Conclusion
Discussion ongoing. Please refrain from renaming the article until a consensus is reached.
