Season 5

September 1, 1997

Strong enough to survive their fiery launch into orbit, sophisticated enough to provide life-saving images or relay tens of thousands of phone calls at the same time. By monitoring weapons systems and troop movements, these "eyes in the sky" may be the difference between security and annihilation. From the futuristic visions of a British sci-fi writer to creations of a German rocket designer for the Nazi war machine to the Cold War technological race, we review the satellites that link our world.

September 7, 1997

To some it was a miracle. Others call it the triumph of illiteracy. Somewhere between adoration and scorn. Somewhere between the carrier pigeon and television. There was and is radio. We take radio for granted. Perhaps think of it as a second rate medium. A poor relation to our pride and joy, television. But fewer than a hundred years ago, the discovery that people could communicate over great distances without wires, galvanized the world to a degree that has been equalled.

September 21, 1997

Probably Thomas Edison’s best-known invention is the electric light. But the familiar light bulb is only the most obvious element of Edison’s accomplishment. He also created from scratch a delivery system for his light. His invention literally changed the world, putting the power of electricity at our fingertips. In 1878, Edison said: “The electric light is the light of the future. And it will be my light.” This is the story of how he and his team raced against competitors to make good his word.

September 22, 1997

Thomas Edison registered over 1,000 patents, but his favorite invention was one of his first. Rare photographs and early recordings show how the young inventor and his team outfoxed Alexander Graham Bell.

September 28, 1997

Viewer discretion is advised for those with vertigo! Featuring rare construction footage and interviews with steely-nerved iron workers who risked death to build them, we climb to the top of the world's tallest, most innovative, and most thrilling structures, including Seattle's Space Needle, Toronto's CN Tower, and Las Vegas's Stratosphere. The architects who designed these astounding buildings explain how each broke the boundaries of architecture at the time it was built.

Reviews the revolution in home improvement and glimpses the kitchen of tomorrow. Included: the development of the stove, sewing machine, refrigerated air, washing machine, vacuum cleaner, toaster, and mixer.

October 12, 1997

Examines the history of radar, focusing on its role in the Allies’ victory in WWII–from the Chain Home Network, rudimentary radar towers that ringed England’s eastern coast, to the role of Boston’s MIT in developing a smuggled English secret, the cavity of magnetron.

From Sherlock Holmes' examination of the physical evidence at a crime scene to today's DNA technology, we review the history of crime detection through the use of forensic science.

October 26, 1997

Welcome to the center of the American economy, where nearly $90-million changes hands each minute.

Journey inside the top-secret headquarters of NORAD–the North American Aerospace Defense Command–a binational military command composed of the United States and Canada. Established in 1958 during the height of the Cold War, NORAD’S initial mission was air defense against a bomber attack by the Soviet Union. We see how its primary mission has changed through the years, and go inside the Cheyenne Mountain Operations Center, one of history’s most ambitious underground building projects.

Feel the earth move under your feet and dig into the fascinating history of earthmoving equipment–from invention of the simple spade to today’s powerful steam shovels. Meet the legendary giants like John Deere, Jerome Case, and the founders of Caterpillar, who helped forge America’s monolithic construction industry.

November 3, 1997

Everyday 3-million passengers board the 10,000 aircraft flying at any given moment. Go behind the scenes at international airports to see the inner workings that make commercial air travel possible–from ground control in air traffic towers, the plane's cargo holds and high-tech security, and back to earth at customs.

November 4, 1997

From hollow-reed snorkels to mini-submarines equipped with video cameras, curiosity compelled inventors to conceive of innovative devices to dive ever deeper into earth’s last frontier. Explore the ocean floor using the latest in technology, and examine biological and geological discoveries culled from the sea’s depths.

January 1, 1998

In 1973, a desperate America, starved by an OPEC embargo, began construction on an 800-mile lifeline for its insatiable oil hunger. We’ll examine this technological triumph, built over impenetrable mountains and tundra, where temperatures drop to 75 below zero. We also study its impact on a fragile ecological system.

January 18, 1998
