Real Underground Tunnels, Cities, and Bases (DUMB’S) Video Documentary

Chapter 4 – 1991: 130+ DUMBS Worldwide

Table of Contents: Earths Ancient Secrets

Experts, scientists, and ex veterans say there are over 130 active D.U.M.B.s in the U.S. alone, costing billions each, connected by tunnel networks for military research, elite survival, biogenetic experiments, extraterrestrial (EBE) alien research or illicit activities.

Deep Underground Military Bases (DUMBs), along with extensive underground tunnels and facilities, are real and serve critical military and civilian purposes worldwide.

DUMB’s are made by some of the smartest people in the world. Ironic, right? Watch DUMB video documentaries below, and send to the friend who calls you a conspiracy theorist. Dont listen to America24, listen to DARPA themselves.

The Defense Advanced Research Projects Agency (DARPA), originally established as the Advanced Research Projects Agency (ARPA) on February 7, 1958, by President Dwight D. Eisenhower.

DARPA is a research and development arm of the United States Department of Defense dedicated to pioneering breakthrough technologies for national security. It was created in direct response to the Soviet Union’s launch of Sputnik 1 in October 1957, which sparked fears of a “technological surprise” and highlighted America’s perceived lag in space and advanced military capabilities; the agency aimed to prevent future such shocks by driving high-risk, high-reward innovation far beyond immediate military needs, collaborating with academia, industry, and government partners.

Over the decades, DARPA has famously funded transformative projects like the ARPANET (the precursor to the modern Internet), stealth aircraft technology, GPS, advanced robotics, AI, and countless other advancements in areas such as materials science, cybersecurity, and biotechnology, while maintaining a lean, flexible “DARPA model” that relies on temporary program managers and short-term contracts rather than permanent labs or bureaucracy to foster radical, often revolutionary ideas that maintain U.S. military technological superiority.

The Cheyenne Mountain Complex (often referred to as the Cheyenne Mountain bunker or NORAD facility) is a fortified underground military installation carved deep into the granite of Cheyenne Mountain near Colorado Springs, Colorado.

Construction began in 1961 under the supervision of the United States Army Corps of Engineers, with excavation starting on May 18, 1961, and the facility becoming fully operational in February 1967 (with NORAD’s Combat Operations Center activating in 1966), at a cost of approximately $142.4 million. It was built primarily for the North American Aerospace Defense Command (NORAD), a joint U.S.-Canada organization established in 1958, to serve as a hardened command and control center capable of withstanding a direct nuclear attack from Soviet bombers or missiles during the height of the Cold War. The mountain’s solid granite structure, combined with engineering features like massive blast doors and shock-absorbing springs supporting the internal buildings, was designed to protect personnel, computers, and operations, ensuring continuous aerospace warning, air defense coordination, and survivability in the event of a nuclear exchange targeting North America.

These structures are engineered for protection against attacks, natural disasters, or to ensure operational continuity. Prominent U.S. examples include the Cheyenne Mountain Complex in Colorado, excavated deep beneath granite to house NORAD’s alternate command center with shock-mounted buildings, independent power, water, and air systems capable of withstanding massive blasts; the Raven Rock Mountain Complex (Site R) in Pennsylvania, often called the “Underground Pentagon,” which provides emergency operations for the Department of Defense and supports continuity of government; and the Mount Weather Emergency Operations Center in Virginia, managed for FEMA and designed as a high-security bunker for federal leadership during crises.

Military applications also extend to networks of underground missile silos, such as those at Minot Air Force Base in North Dakota for ICBMs, and vast tunnel systems like those in Gibraltar (built by the British military over centuries for defense and storage). On the civilian side, extensive underground infrastructure includes transportation tunnels, subways, utility networks, and emergency shelters, while some nations maintain large-scale subterranean facilities for strategic resilience, demonstrating that deep underground construction is a established engineering and defensive reality rather than speculation.

Phil Schneider was a geologist and explosives contractor who worked on secret Deep Underground Military Bases (DUMBs). He worked for one of the most notorious American concrete and construction companies still around today.

Morrison-Knudsen (M-K), founded in 1912 in Boise, Idaho, by Harry Winford Morrison and Morris Knudsen, grew from humble beginnings on small irrigation and canal projects in the American West into one of the world’s leading heavy civil engineering and construction firms. The company played a pivotal role in some of the 20th century’s most iconic infrastructure projects, including serving as a key member of the Six Companies consortium that built the Hoover Dam, constructing the San Francisco-Oakland Bay Bridge, developing Pacific naval air bases during World War II, contributing to the Hanford Engineering Works, the Trans-Alaska Pipeline, ICBM systems, and even the Vehicle Assembly Building at Kennedy Space Center. Headquartered in Boise, M-K expanded globally across continents, tackling dams, bridges, tunnels, railroads, highways, pipelines, airports, and military facilities, later sold and restructured as AECOM.

in 1979 how he helped drill into an alien base under Dulce, New Mexico, triggering a deadly firefight between U.S. forces and extraterrestrial “Grays” that left him severely injured. He lectured widely about black-budget underground networks, alien treaties, and government cover-ups until his 1996 death—officially ruled suicide but widely called murder by supporters. Skeptics view him as a fabricator or unstable figure, yet he remains an enduring icon in DUMB and UFO lore.

In the 1994, Phil gained notoriety in UFO/UAP Advanced Alien Technology (AT). Phil was killed in 1996, after many strange events and threats. Phil’s death was ruled a suicide, but this is something we hear too often today.

Hermetic Sealed DUMBS:

A hermetic seal is an airtight, gas-tight barrier that completely prevents the passage of gases, liquids, moisture, or contaminants in either direction, originally derived from alchemical traditions linked to Hermes Trismegistus and now commonly achieved through materials like glass-to-metal fusions, compression seals, welding, or specialized epoxies to ensure long-term isolation in extreme environments. In submarines, a prominent real-world example is the hull penetrator or feedthrough for electrical cables and connectors, which maintains a hermetic seal at points where wiring passes through the pressure hull to protect internal electronics from high-pressure seawater ingress while allowing data and power transmission; similarly, hermetic connectors (often glass-to-metal sealed) are used in naval and submarine applications to safeguard sensitive systems against corrosive saltwater and pressure differentials.

For deep underground military bases (DUMBs)— highly classified, subterranean facilities buried deep within mountains or earth for continuity of government, command, or secret operations during nuclear threats—hermetic sealing principles apply to blast doors, airlocks, ventilation systems, and environmental controls that create isolated, pressurized compartments to maintain breathable air, block radiation fallout, chemical agents, or external flooding, ensuring self-contained habitability in sealed environments far below the surface, though verifiable details on hardened military installations like the Cheyenne Mountain Complex.

Inside DARPA’s SubT Challenge: Mapping the Unseen Underground

The DARPA Subterranean (SubT) Challenge Competitors’ Day was an informational event hosted by the Defense Advanced Research Projects Agency on September 27, 2018, in Louisville, Kentucky, to introduce the vision, timeline, and details of the upcoming DARPA Subterranean Challenge. Announced in July 2018, the event aimed to engage potential competitors, facilitate technical and operational exchanges, and encourage the formation of cross-cutting teams with diverse expertise in robotics, autonomy, and related fields to tackle the challenge of rapidly mapping, navigating, and searching complex underground environments—such as human-made tunnels, urban infrastructure, and natural cave networks—for applications benefiting warfighters and first responders. Registration for the Competitors’ Day opened on August 15, 2018, with advance sign-up required for on-site or virtual attendance, and the gathering provided preliminary information about the multi-year competition, which featured three circuit events and a final event in 2021, offering more than $3 million in total prizes across Systems and Virtual tracks.

Elon Musk’s Boring Company: Revolutionizing Underground Digging: “Tunnels & Roads to Beat Traffic”

Did the CIA and DARPA help Start The Boring company?

The Boring Company, founded by Elon Musk in 2017 (initially as a SpaceX subsidiary before spinning off independently in 2018), is an American infrastructure and tunnel construction firm dedicated to revolutionizing urban transportation by digging safe, fast, and low-cost underground tunnels to alleviate surface traffic congestion. Born from Musk’s frustration with Los Angeles gridlock—sparked by a 2016 tweet declaring he would “build a tunnel boring machine and just start digging”—the company aims to create multi-layered, 3D road networks using advanced tunnel boring machines (TBMs) like the Prufrock series, which promise dramatically faster and cheaper excavation than traditional methods. Its flagship operational system is the Vegas Loop in Las Vegas, a network of tunnels transporting passengers in Tesla vehicles (with over 3 million riders to date across stations connecting the Convention Center, resorts, and more), while ongoing or planned projects include expansions in Las Vegas, the Music City Loop in Nashville (with tunneling progress toward 2027 openings), a pilot Dubai Loop starting construction in late 2026, potential connections in Orlando for Universal theme parks, and various R&D tunnels. Though early visions included ultra-high-speed Hyperloop pods and ambitious inter-city links, the company has focused on practical, Tesla-driven urban loops to enable rapid point-to-point travel, minimize surface land use, and transform cities by making tunnels a viable alternative to above-ground congestion.

DC Long Full Video Interview: DUMBS and Monolithic Slabs Levitating with Anti Gravity

Veteran Reveals Levitating Monolith in Secret Underground Base. Gravity-Defying Slab Hidden Deep Beneath Fort Bragg. An Army Vet’s Chilling Encounter: A Floating 100-Ton Stone Underground.

The story of the mysterious monolithic slab in an underground military base, as recounted by U.S. Army veteran DC Long (featured in the Shawn Ryan Clips video titled “Army Veteran Recounts Mysterious Monolithic Slab in an Underground Military Base”), begins with his family’s deep ties to the military world. DC’s father owned a construction company called TurnKey, specializing in residential and commercial projects, including the pouring of monolithic slabs—large, single-pour concrete foundations common in building. Their work frequently intersected with government contracts through the Army Corps of Engineers, but this particular job stood out due to its extreme secrecy and personal connections.

These connections stemmed from DC’s father’s hunting trips across states like North Carolina, Arkansas, Montana, and Colorado, where he befriended operators from Delta Force—elite special operations soldiers based at Fort Bragg. Such relationships occasionally led to informal subcontracting opportunities that bypassed standard bidding processes. One day, DC’s father received a call requesting their expertise for a classified project at “Range 19,” a remote training area near Fort Bragg. The job involved setting up a shoot house—an indoor live-fire training facility used by special forces for close-quarters combat simulations. It was going to be a secret underground testing site for reverse engineering alien technology, (AT), like anti gravity, and other advanced scientific research. The escort arrived in a windowless van, a standard measure for sensitive transport to prevent visual identification of routes or locations. DC and his father were instructed to keep their heads down during the drive, heightening the sense of intrigue and potential danger. Upon reaching the site, which appeared to be an ordinary trash dump on the surface, they were led to a concealed concrete door embedded in the ground. This entrance opened to a freight elevator with unmarked buttons, descending into an underground facility far removed from public view. As they stepped off the elevator into a vast, dimly lit hangar-like space, the atmosphere felt industrial yet eerily controlled. Armed Delta operators—familiar faces from his father’s hunting circles—provided security, issuing stern warnings that looking up or deviating from instructions could result in being shot on sight. The task at hand was straightforward: prepare forms, rebar, and pour concrete for the shoot house walls and floors. The environment was utilitarian, with concrete surfaces, overhead lighting, and the faint echo of distant machinery. While working, DC glanced past the operators and spotted something extraordinary in an adjacent area: a giant monolithic slab suspended in mid-air. The object measured roughly 20 feet long and 7 feet tall, with an estimated weight well over 100 tons based on its granite-like density. It appeared to be made of natural stone, possibly granite, but possessed an unusual sheen—somewhere between polished and translucent—that caught the overhead lights in a way that suggested depth or internal properties beyond ordinary rock. What made the slab truly baffling was its complete lack of visible support. DC knelt down and peered underneath, confirming there was “absolutely nothing” holding it up—no pillars, cables, hydraulics, or magnetic apparatus detectable to the naked eye. The slab simply hovered, defying gravity in a manner that challenged everyday physics. Adding to the surreal scene, two large boulders sat behind it, and one operator casually manipulated one with a single hand, spinning it effortlessly as if it were weightless and frictionless, with no wobble or resistance. Compounding the visual anomaly was an intense, silent vibration emanating from the slab. DC described it as feeling like standing next to massive concert speakers, where the bass permeates your entire body without any audible sound—just a deep, permeating resonance that vibrated through bones and organs. This haptic feedback suggested some form of advanced energy field or acoustic technology at play, evoking comparisons to theories of sonic levitation or anti-gravity manipulation. The slab’s translucent quality allowed glimpses of what lay beyond it, hinting at possible layered or composite construction rather than solid stone. In conspiracy circles, such features often tie into lore about recovered extraterrestrial materials or reverse-engineered tech capable of nullifying gravitational forces. The effortless boulder-spinning further implied mastery over inertia and mass, reminiscent of claims surrounding Ed Leedskalnin’s Coral Castle, where one man allegedly moved multi-ton coral blocks alone using unknown methods. After only 15-20 minutes underground, the team completed their initial setup and returned to the surface via the elevator. Upon re-entering the same space later, everything anomalous had vanished without trace. The monolithic slab, the two boulders, and any associated equipment were completely gone, leaving the area as an empty, ordinary hangar. No debris, no marks on the floor—nothing to indicate the objects had ever existed there. DC reflected on his lack of immediate curiosity at the time, attributing it to the normalcy of working around elite operators and the job’s demands. He trusted the men involved and assumed the phenomena were part of classified experimentation, perhaps involving novel weapons systems or propulsion tech. The event lingered in his memory, resurfacing years later amid broader discussions of hidden military capabilities. This encounter fits into larger narratives of Deep Underground Military Bases (D.U.M.B.s), where whistleblowers describe facilities housing exotic technologies far beyond public knowledge. While DC’s account avoids direct alien claims, the levitation and vibration strongly suggest anti-gravity or field-based manipulation, fueling speculation about government possession of such tech—possibly derived from UFO recoveries or independent breakthroughs. Ultimately, the monolithic slab remains one of the most compelling modern veteran testimonies in underground base lore. Its disappearance, combined with the effortless manipulation of massive stones, leaves an indelible impression of hidden wonders beneath familiar military landscapes, challenging skeptics to explain how such feats could occur without revolutionary physics being openly acknowledged.

What was the base?

Fort Bragg, located near Fayetteville in North Carolina, stands as one of the largest and most significant U.S. Army installations in the world, currently home to over 52,000 military personnel and serving as the premier hub for the Army’s airborne and special operations forces. Established in 1918 as Camp Bragg and later designated a permanent fort in 1922, it has long been synonymous with elite units such as the XVIII Airborne Corps, the 82nd Airborne Division, and U.S. Army Special Operations Command, playing a pivotal role in training and deploying globally responsive forces. After a temporary rename to Fort Liberty in 2023 amid efforts to remove Confederate-associated names, the base was redesignated back to Fort Bragg in early 2025—this time honoring World War II paratrooper Private First Class Roland L. Bragg, a Battle of the Bulge hero, rather than the original Confederate general. This sprawling installation, spanning over 251 square miles across multiple counties, remains a cornerstone of American military readiness, supporting rapid deployment capabilities, advanced training, and a vibrant community of soldiers, families, and civilians.
