Dyatlov Pass: Avalanche, Military Testing, or Something Worse?

Unsolved History Archives — Thu, 09 Apr 2026 23:00:00 GMT

On February 1st, 1959, nine experienced hikers set up camp on a remote Siberian mountainside. Sometime that night, something made them slash open their tent from the inside and flee barefoot into -40° winds. None of them survived.

When searchers found the bodies weeks later, the evidence made no sense. Five had frozen to death — but four had suffered crushing internal injuries that the medical examiner said required more force than any human could deliver. One was missing her tongue and eyes. The Soviet government classified the case and sealed the files.

In this documentary, we trace the full story of the Dyatlov Pass incident — from the hikers themselves and their careful preparations, through the harrowing search and discovery, the baffling autopsy results, the Soviet investigation that ended with no real answers, and the decades of theories that followed: avalanche, military testing, infrasound, katabatic winds, and stranger explanations still.

65 years later, we're no closer to understanding what happened on Dead Mountain that night.

We Found an Alien Signal in 1977 and Nobody Noticed

Unsolved History Archives — Wed, 08 Apr 2026 23:00:00 GMT

On August 15, 1977, a volunteer astronomer named Jerry Ehman was scanning through printouts of radio data from Ohio State University's Big Ear telescope when he spotted something impossible — a signal 30 times stronger than anything they'd ever recorded from space. He grabbed a red pen and wrote one word in the margin: "Wow!"

For 72 seconds, something powerful and precise broadcast at the exact frequency of hydrogen — the universal channel any advanced civilization would know. Then it vanished. Nearly five decades later, no one has been able to explain it.

In this documentary, we trace the full story of the Wow! Signal — from the Big Ear telescope and the SETI program that made the detection possible, to the decades of follow-up searches, the controversial comet theory, the Fermi Paradox, and what modern science is doing to finally answer the question: is anyone out there?

Bob Lazar's Biggest Claim Just Got Verified

Unsolved History Archives — Tue, 07 Apr 2026 23:00:00 GMT

What really happened to Bob Lazar in the Nevada desert? In 1989, a man claiming to have reverse-engineered alien spacecraft at a secret facility near Area 51 went public on Las Vegas television. His story would divide the UFO community, frustrate government officials, and captivate the world for over three decades.

Tonight, we examine everything — the claims, the credentials, the contradictions, and the questions that still don't have good answers.

The Roswell Discovery That the Government Still Won't Explain

Unsolved History Archives — Mon, 06 Apr 2026 23:00:00 GMT

In the summer of 1947, something crashed in the desert outside Roswell, New Mexico.
The United States Army Air Force initially announced they had recovered a "flying disc."
Twenty-four hours later, they changed their story.

What followed was decades of cover-up, contradictory official explanations,
whistleblower testimony, and one of the most debated events in modern American history.

This documentary examines the full Roswell story — the crash, the witnesses,
the military response, the debris, and the question that has never been
satisfactorily answered: what exactly did they find out there in the desert?

They Lost 2 Hours. No One Could Explain It. | The Betty & Barney Hill Incident

Unsolved History Archives — Sun, 05 Apr 2026 03:46:54 GMT

On the night of September 19, 1961, Barney and Betty Hill were driving home through
the White Mountains of New Hampshire when they encountered something they could never
fully explain. What followed would become the most documented and debated alien
abduction case in American history.

This documentary explores the full story — from the initial sighting on a quiet
mountain road, to the mysterious missing time, the physical evidence, and the
groundbreaking hypnosis sessions with Dr. Benjamin Simon that revealed details
neither of them had consciously remembered.

We examine the science, the skepticism, and the deeply human story at the heart
of it all — two remarkable civil rights activists whose lives were changed forever
by a single night in the mountains.

They Saw It Land. The Military Covered It Up. | The Rendlesham Forest Incident

Unsolved History Archives — Sun, 05 Apr 2026 23:00:00 GMT

n December 1980, United States Air Force personnel stationed at RAF Woodbridge
in Suffolk, England, witnessed something in the nearby forest that they could
not explain. Over the course of three nights, multiple military witnesses —
including a deputy base commander — reported unexplained lights, a landed craft,
and physical evidence that has never been fully accounted for.

This is the Rendlesham Forest incident. Britain's most compelling UFO case.
And one that the military has never satisfactorily explained.

We examine the witnesses, the evidence, the official response, and the
questions that remain unanswered over four decades later.
