Episode 1 - Trans-Siberian Railroad

It’s the longest, most expensive and complicated railroad ever built. Ordered by the Czar in an effort to save his empire and unify his country at the twilight of the 19th century, the Trans-Siberian Railroad nearly tore Russia apart. Intended in part for defense, the railroad provoked a war, crossed great lengths over treacherous terrain, and encountered logistical and economic failures. Ironically, “enemies of the state” built the railroad–men sentenced to hard labor in Siberian prisons.

Episode 2 - Castles & Dungeons

Some of the most imposing structures ever built, medieval castles withstood both bloody assaults and the test of time. Designed like machines with nearly every architectural detail devoted to defense, castles represented the perfect fusion of form and function. Journey back to that unruly era as we examine the complexity of their construction and the multipurpose they served–homes to kings and nobles, economic centers, courthouses, treasuries, prisons, and torture chambers.

Episode 3 - Ice Road Truckers

Based on the book Denison’s Ice Road by Edith Iglauer, the episode detailed the treacherous job of driving trucks over frozen lakes, also known as ice roads, in Canada’s Northwest Territories. After 2000, reruns of the documentary were aired as an episode of the series Modern Marvels instead of Suicide Missions/Dangerous Missions.

Episode 4 - Winter Warriors

Traces the story of the U.S. Army’s legendary 10th Mountain Division. They were formed after WWII began, specifically to fight in high, rugged mountain conditions. After training in the Colorado Rockies, they were sent to Italy’s Apennines to take on well-entrenched Germans. Using a combination of mountain skills and raw courage, they drove the Germans back, and helped win the war in Italy. Later, former members of the 10th helped create many of the country’s ski resorts, including Aspen and Vail.

Episode 5 - Booby Traps

All it takes to set off a booby trap is an unsuspecting victim lifting, moving, or disturbing a harmless-looking object. Booby traps continue to worry law enforcement; made from easily acquired items, information detailing their construction and needed materials are accessible through the mail–anonymously! And unlike a land mine, they can be anywhere. We detail the history of booby traps–from the ancient Egyptians, Chinese, Greek, and Romans to the Middle Eastern crisis and the War on Terrorism.

Built during a span of well over 1,000 years, they stand as cultural and engineering marvels of staggering proportions. But many things about these monuments, including the exact methods used to construct them, remain tantalizingly obscure. Travel back in time as we investigate their evolution–from the earlier mastaba to the Step Pyramid, Bent Pyramid, and of course, the magnificent necropolis at Giza.

Episode 84 - The Berlin Wall

During the Cold War, the Berlin Wall stood as a forbidding barrier in an embattled world. Erected in August 1961, the Wall system stretched 103 miles through and around Berlin, locking in 1.3-million people. 261 died trying to get over, under, around, and through it. We review the daunting devices within the Death Strip–one of the deadliest obstacle courses ever–and the ingenious ways people ran it. When the Wall fell with a thud in 1989, its pieces became souvenirs or were recycled for new roads.

Episode 85 - Toys

All aboard the nostalgia express as we take a trip through the past to enjoy toys of our youth–the ones we can't forget and those that some of use never gave up! This is the real toy story! We take a look at five categories of boys' toys and see what relationship they have had on the development of young minds; talk with collectors of antique and specialty toys; and visit companies that make electric trains, Matchbox Cars, GI Joe action figures, and LEGO Bricks, among others.

Episode 86 - Engineering Disasters 5

Examines some of the most notorious engineering failures of recent years and asks what went wrong and what we learned from them. We take viewers to the southern coast of Louisiana, where a misplaced oil rig caused an entire lake to be sucked into an underground salt mine; review the 1972 Buffalo Creek dam disaster; revisit the Exxon Valdez oil spill; see how radio and TV antenna towers collapse with alarming regularity; and look at the collision of two California icons–freeways and earthquakes!
