Scott Wolter investigates the mysterious disappearance of vast amounts of copper from Lake Superior. Through scientific testing a connection is made to a pre-historic civilization and the Bronze Age.

Megalithic monuments linked together by electromagnetic energy... Prehistoric ruins arranged across vast distances in straight lines... And advanced mathematics carved into landmarks more than 5000 years ago. Were ancient man's spectacular structures built by humans alone? Or do they bear evidence of being designed--and interconnected--by otherworldly visitors?

Why were ancient civilizations around the world so focused on the Orion constellation? While scientists site many earthly connections, researchers suggest this point in the night sky may have been a so-called Stargate, or entry point, for alien life forms. If extraterrestrials have been visiting Earth for thousands of years, might they have originated from the Orion Nebula?

Ever since the military started using sophisticated airplanes, they have sought ways to build an aircraft that can fly undetected, maneuver like a helicopter and fly like a jet. The Nazis were the first to pursue the idea of building a disc-shaped aircraft. After the war, the Americans, Canadians and Russians all were able to build aircraft similar to the German prototype, perhaps based on the concepts smuggled out by German engineers. This episode looks at top secret flying saucer designs of the Air Force, with specific dates, times and locales of flights that may point to the real explanation behind the many UFO sightings beginning in 1947, and why the saucer design was abandoned for stealth technology.

Join us for a detailed examination of the little-known phenomenon of USOs, or "Unidentified Submerged Objects", an advanced type of UFO that can operate just as efficiently in water as in the atmosphere. These supposed otherworldly vessels have been reported, some believe, as far back as ancient Egypt. Others believe that USOs were reported by Alexander the Great and Christopher Columbus, and might even involve the lost city of Atlantis. Highlights include the 1967 "Shag Harbour Incident", a government-documented USO crash off the coast of Nova Scotia, Canada, and a trip to the area around Laguna Cartegena in Puerto Rico, a reported hotbed of USO activity. Interviewees include the US Navy's Bruce Maccabee, UCLA's Kathryn Morgan, as well as USO and UFO experts Stanton Friedman, Bill Birnes, and Preston Dennett.

In 1980, three young military men were sent into a UK forest to investigate strange lights. They reportedly encountered a spacecraft of unknown origin. When one of the men touched it, he claims to have received telepathically a long sequence of binary code, which he later wrote down and translated. The military ordered them to never speak about the incident. Why do such UFO encounters continue to be kept under wraps, and what might they reveal about our ancient past?

Super-heated death rays... High-tech rockets... Powerful sonic weapons... Are these examples of modern day science or could these technologies have originated thousands of years ago? Is it possible that early man possessed scientific knowledge far beyond that of our own century? Ancient texts, folklore and art suggest humans witnessed disc-shaped flying machines and fire-spewing chariots. Could these be accounts of flying saucers and rocket ships? And if so, was advanced technology left here by visitors from the stars? Did mankind's quest to unlock the secrets of levitation, anti-gravity and laser technology merely spring from our imaginations or did these ideas come from otherworldly beings?

Scott Wolter investigates a burial site in the mountains of Arizona, only to discover it may belong to a medieval Englishman.

Most people know that the Federal government finally locked up Al Capone for tax evasion, and believe that the man who really brought him down was his archenemy, U.S. Treasury Agent Eliot Ness. But there's much more to the story. After the St. Valentine's Day Massacre in 1929, a group of Chicago businessmen, "The Secret Six", decided to put an end to Capone's 7-year reign as crime king. They enlisted President Hoover and helped to finance intelligence agents to unravel Capone's business operations. Hoover sent two groups of special agents to infiltrate the Capone gang. We look at new evidence, uncovered by a university professor, that shows why Capone was indicted on income tax evasion instead of breaking Prohibition, and why a plea bargain was abruptly taken off the table by the trial judge.

Rennes le Ch teau is a small village in the Pyr n es of Southern France. It's a quiet place until tourists arrive hunting its secrets. According to legend, the Knights Templar brought the Holy Grail here for safekeeping. Those who come on pilgrimage think the Grail is very different than history records. Was it proof of marriage between Jesus and Mary Magdalene? Did it verify their bloodline survived? Permission has been granted to dig in Rennes le Ch teau...and history or legend is about to change.

Meteors, comets, and asteroids cross the solar system to offer clues about our planet and universe. Can they destroy civilizations? Did they wipe out the dinosaurs? Have they brought life to our planet? And when will the next one hit? Aided by elaborate animation and live-action footage, we learn what these mysterious space rocks really are and imagine what likely happened 65-million years ago, when an object plowed into the Yucatan Peninsula. We see how certain spectacular meteor falls advanced our understanding of what they are and the danger that they pose. We talk to leading experts--astronomers and geologists including David Levy and Carolyn Shoemaker, co-discoverers of the Shoemaker-Levy comet that fell into Jupiter in 1994. And we talk to NASA scientists about recent missions to asteroids and comets and speculate on ways to move Earth-threatening asteroids and comets out of our way. Because it isn't a question of if but when the next deadly impact will take place.
