In Southern California, raging wildfires set the stage for a massive mudslide killing 14 people at a campsite. A tornado targets an Oklahoma truck driver. And an Indonesian volcano erupts, smothering nearby citizens with a blanket of ash.

Mother Nature unleashes a barrage of attacks around the globe. In San Francisco, a powerful earthquake levels bridges, crushing commuters underneath. A rolling avalanche devours climbers in the Himalayas. And in Nebraska, lightning strikes an unlucky storm chaser.

Mother Nature attacks Gulf Coast residents with the worst hurricane in US history. A tornado rips through a hardware store, turning merchandise into lethal weapons. And in Haiti, a monstrous earthquake claims countless victims.

From breakthrough technologies to never before seen weapons and defense systems, Secret Access: Superpower is an all-access pass to America's military might, featuring the most modern weapons taking on the age old challenges of terrorism, war, bomb threats, close combat, the deepest missions of sea and death-defying airborne fights. Hosted by actor/director and military enthusiast, Peter Berg, along with Peter Singer, the noted defense expert and NY Times best-selling author, this two-hour special leads viewers down the war path of America's most remarkable munitions of past and present in an exciting and surprise-filled journey behind the scenes of the world's last remaining superpower.

Produced with the cooperation of leading Civil War historian Winston Groom, author of Forrest Gump, this 2-hour special is a personal look at two iconic leaders of the Civil War. Surprising details reveal the bold choices and almost godlike power Ulysses S. Grant and Robert E. Lee summoned on decisive battlefields like Vicksburg and Gettysburg that, within days of each other, turned the tide of the war. This special features a unique perspective, exploring how these men changed the course of American history.

A steam pipe explosion rocks New Yorkers on a summer day in Midtown Manhattan. Boston's Big Dig highway project suffers a major setback when sections of a tunnel ceiling fall onto the roadway. Rush hour in Minnesota turns deadly, as a bridge plunges into the Mississippi River. An air show in Mannheim, Germany comes to a tragic end when a Chinook helicopter crashes along the Autobahn killing 46 people. A tanker truck explodes on an Oakland freeway overpass, causing the structure to collapse. And a mud volcano near a natural gas drilling site erupts in Indonesia, leaving villages buried 16 feet deep. We'll explore what engineering and structural failures caused these events, and the changes the catastrophes have wrought.

It's full steam ahead when we drop in at Jay Leno's garage as Jay fires up two of his classic steam cars and takes viewers for a couple of rides. Jay also shows off his 11-ton steam engine built in 1860, back when pigs had to be slaughtered to keep it lubricated. In northern Nevada, fire up a coal burning boiler and get a 100-year-old steam locomotive chugging across the rugged landscape. In New Orleans, board an authentic paddlewheel steamboat. Trek to the Southern California desert where geothermal steam rushes up from the ground and drives electricity producing turbines, powering over 300,000 homes. In New York City, find out why manmade steam surges into some of the world's most famous skyscrapers. Steam clean some very dirty machines, and do a little laundry, too. And ride a steam-driven carousel and play with some strange, steam-powered robots that are part of a movement called--what else--"steampunk."

From stars, galaxies and moons to subatomic particles, black holes and invisible phenomena, discover the most bizarre, mysterious and exotic things in our universe. Learn about actual alcohol clouds floating in space that are filled with organic molecules which produce complex compounds like ethyl alcohol, the stuff we drink. Is there a hypothetical planet that exists beyond Neptune and what are pulsar planets? Mini Black Holes are a theoretical idea, but if they were to exist, some theorists speculate that they might have been produced shortly after the "Big Bang." Finally, delve into dark matter, a hypothetical form of matter that is invisible yet it exists everywhere.

Some of the world's leading physicists believe they have found startling new evidence showing the existence of universes other than our own. One possibility is that the universe is so vast that an exact replica of our Solar System, our planet and ourselves exists many times over. These Doppelganger Universes exist within our own Universe; in what scientist now call "The Multiverse." Today, trailblazing experiments by state of the art particle colliders are looking for evidence of higher dimensions and Parallel Universes. If proof is found, it will change our lives, our minds, our planet, our science and our universe.

Every year, thousands of objects both natural and manmade plummet through our atmosphere and crash into the Earth. These menacing messengers from the sky provide scientists with amazing insights into the natural, and not so natural, phenomena of the cosmos. From space rocks crashing through homes to cosmic boulders triggering mass extinctions to rocket parts landing on front lawns, explore objects that fall from the heavens, such as asteroids, comets, meteor showers and space debris.

Centuries ago the prophet Nostradamus had visions of the end of our modern world. Now, scholars decipher his mysterious predictions and learn of terrible tragedies and catastrophic events that threaten to annihilate global populations. Nostradamus has successfully predicted the rise of Hitler, the assassination of John F. Kennedy, the detonation of the atomic bomb, and countless other events. Many fear that the remaining unfulfilled prophecies of Nostradamus will manifest before our very eyes. At Radius Engineering in Texas, Walton McCarthy shows state of the art underground shelters to a concerned family and in South Florida, Billy Carson of Fort Terra Nova meets with a prospective client interested in joining an underground shelter community large enough to house over 350 people.

On June 20, 1941, the US Submarine O-9 headed out of Portsmouth, New Hampshire, and nosed below the surface carrying 33 hands and never returned. Inquiries into her sinking failed to find answers. But 60 years later, she was rediscovered. Today, our team of Deep Sea Detectives heads out with the National Undersea Research Center to take the first ever video survey of the wreck in an attempt to solve this long forgotten mystery.

June 6, 1944--the destroyer USS Meredith joined the D-Day invasion of Normandy. Her 5-inch guns pounded German coastal batteries as American troops fought their way ashore at Utah Beach. On the night of June 7, the Meredith moved out into dangerous mine-infested waters to defend the Allied ships against a new threat, fast German torpedo boats. Shortly before 2 a.m., a huge explosion ripped through the destroyer. Did she hit a mine? Sail into the path of a torpedo? Or was the Meredith struck by a top-secret German glide bomb, the world's first guided missile? Teams of deep-water detectives use today's cutting-edge technology to make this wreck "tell its story", along with CGI graphics, expert interviews, archival materials, and dramatic reenactments.
