Satellites
Aired on Aug 17, 1997Strong 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.
Radio: Out Of Thin Air
Aired on Aug 24, 1997To 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.

Aired on Oct 19, 1997Journey 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.

Aired on Nov 04, 1997Aqueducts: Man Made Rivers Of Life
Aired on Jan 04, 1998Many 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.
American Steel: Built to Last
Aired on Jan 18, 1998For over a century, the US steel industry was a powerful symbol of the nation’s industrial might. Steel helped explode the stock market into an overnight powerhouse, and transformed a country of farmers and merchants into a nation of visionary builders. But America’s domination of the market would meet new challenges in the 1970s.
