There is no more potent demonstration of man’s resolve than the design and construction of tunnels–avenues that slice through a conspiracy of elements in the single-minded determination to connect two points. Whether underwater, blasted through solid rock, or negotiating the shifting strata of earth’s unstable crust, we explore the design and engineering of famous tunnels…and the motivation behind them.

The White House is more than the President’s residence–it is a structure that both reflects the office and affects the man. As architecture, it suggests America’s consensus on the nature of the Presidency. It is at once humble, genteel and stately. It avoids the aristocratic airs of European leadership in favor of an accessible office. And history has demonstrated that men exposed to the grace of the White House are absorbed by its American allure. It makes politicians “Presidential”. It lifts them to a loftier plane of purpose. The President may live in the White House, but it is America’s home.

Many rivers quenched the thirst of millions in the American west and around the world. Without these aqueducts, some of the earth’s largest cities would turn into gigantic ghost towns. Their technology has been in use for over two thousand years. But today these engineering marvels cost billions of dollars to build, requiring thousands of men to toil for years on end. Aqueducts have made some men famous and others fabulously wealthy. In Los Angeles one man’s vision took one hundred thousand men to complete and a great city was truly born. In Northern California the most famous conservationist of our time waged the political fight of his life in an attempt to save one of nature’s most spectacular valleys from San Francisco’s demand for more water.

Set the sedan’s safety brake and hop on your “hog” for a 2-hour high-speed history of the motorcycle–from the 1868 “steam velocipede” to the early 20th century, when they were a low-cost alternative to automobiles; from Harley-Davidsons preferred by Hell’s Angels and police to motocross riders who take bikes into the air and onto the dirt. We also look to the motorcycle’s future, featuring Jay Leno’s jet-propelled Y2K sportbike and Erik Buell’s bike-without-a-gas-tank creation.

SECRET RUSSIAN AIRCRAFT OF WORLD WAR II reveals how, despite the ever-present danger, Soviet designers mastered technical hurdles astonishing even by today's standards. Rare footage, photos and plans show their creations: a swept-wing, delta aircraft design, a rocket-powered fighter, a long distance fixed-wing aircraft which helped inspire the U-2 spy plane, a flying tank prototype, a submarine-bomber combination, and a canard-wing aircraft.

In 1943, a B-25 Mitchell, WWII's most versatile twin-engine bomber, crash-landed in South Carolina. It sank 150 feet to the bottom of a lake and over time was forgotten. Now, 60 years later, a local doctor is determined to raise the giant bomber intact and give it to a museum. Our team--divers, engineers, and preservationists--takes on the job of moving the 20,000-pound bomber to the surface, while faced with the challenges of working in nearly zero-visibility murky waters and the wrath of an approaching hurricane, plus fear that the plane may be breaking apart!

It traps a treasure of energy on the ocean floor, and confounds scientists still trying to solve why it’s so slippery. We’ll venture inside NASA’s Icing Research Tunnel in Ohio, and then it’s off to Salt Lake City’s Olympic Oval which boasts “the fastest ice on Earth.” Dive to the ocean floor to collect and analyze a unique form of ice called methane clathrates–cages of ice encasing pressurized natural gas. Scientists believe that if only one percent of the world’s ice-entrapped methane could be harvested, it would more than double our current supply of natural gas. Other highlights include the search for extraterrestrial ice and a trip inside the studio of a chainsaw-wielding artist as he sculpts a masterpiece
