Oil Fire Fighting

When a burning gusher shoots flames into the air, only a handful of men know how to snuff out the monster. Fighting fire with fire, they place explosives around the flames to blow it out, or douse it with tons of water. The modern world depends on these risk takers, yet their industry began less than 100 years ago. Join us for a scorching hour as we review the rich history of this “breed apart”, and look at modern heat-resistant clothing, new technology, and regulations that protect oil firefighters.

Athens Subway

Under Athens' bustling metropolis, an unique engineering project transformed the city, building a new underground Metro system, while uncovering secrets of its past, alleviating chronic traffic problems, and preparing for the 2004 Olympics. But to dig stations and tunnels in the heart of one of the world's oldest sites of continuous habitation, engineers had to accommodate the largest archaeological excavations conducted to date in Athens. Thousands of invaluable artifacts were discovered, spanning more than 25 centuries. We talk with leading project engineers and archaeologists to explore the difficult balance between progress and preservation. Unique library film records every stage by which gigantic Tunnel Boring Machines cut under some of the most famous architecture of the ancient world. Despite problems and delays, the Athens' Metro finally opened in January 2000. Its dazzling modern stations at the center of the city contain ancient artifacts found at the station sites.

The World's Longest Bridge

Bridges are the lifeline of Japan. Since the 1930s, the island nation has dreamt of linking its many parts as a whole. But WWII diverted the incredible resources needed to accomplish this, and only since 1960 has the dream moved again, slowly, toward reality. The final step in this massive undertaking was the Akashi-Kaikyo Bridge, currently the longest single-span suspension bridge in the world. This marvel of architectonics stands as a testament to the genius of Asian engineering and, judged in a context that perhaps the Japanese understand best, as the most beautiful bridge in the world. We’ll watch it rise, from sketch to completion, and see how it fared during the massive Kobe earthquake.

Japanese Sub at Pearl Harbor

The Japanese attack on Pearl Harbor was a move of unprecedented aggression that shook the U.S. out of its peaceful slumber and into WWII. But for 60 years, veterans of the destroyer USS Ward claimed they sank an enemy submarine outside the harbor more than an hour before the aerial attack began. The wreck was never found, and the story was dismissed. In August 2002, a dive team crossed its path and their find made headlines worldwide. We travel to Pearl Harbor to investigate the midget sub mystery.

Submarine Disasters

When the men and women aboard a modern submarine hear the command to dive, they can take a measure of comfort in the fact that no US sub has been lost in nearly 40 years, though it’s been said that the sea is a more hostile environment than space. The tragedies of former disasters have not been forgotten or squandered and the Navy has been extremely motivated to find ever more effective ways to prevent them. We’ll examine sub disasters to discover what caused them and what they’ve taught us. And as we explore the early history of the submarine–including a sub used in the American Revolution and one used in the Civil War–we follow a modern crew using submarine simulators to train for disasters, study subs in the nuclear age, and explore state-of-the-art rescue technology.

Washington Monument

The US capital boasts many memorials, but none with a more bizarre history than the obelisk erected to America's first president. Over 55 stories high and weighing over 90,000 tons, the Washington Monument stands stalwart in the city's center. From concept to completion, it took 100 years–years filled with mystery, ceremony, conflict, government action, and inaction. Proposed in the late 1700s by a group of prominent citizens and finished in the late 1800s by the Army Corps of Engineers, the exterior is mainly Maryland white marble, while the interior is made of granite, iron…and a few surprises. How did it come together and why did it take so long? Historians tell stories of stalling bureaucracy, secret societies, and triumphant engineering. Stark and daunting on the outside, we let viewers know what's inside.

Chaos in Guadalajara, Mexico, when the city streets explode; an airplane crash outside of Paris that ranks as one of the worst in history; two mining dams in Italy collapse engulfing a village in a tidal wave of sludge; a generation of children in a small Texas town are entombed in the rubble of their school; an oil tanker runs aground off the coast of England and introduces the world to the devastation of the first super spill… EM Engineering Disasters 16 /EM delves into the shocking chain of events leading up to each of these horrific catastrophes and examines resulting technological improvements designed to prevent similar tragedies in the future.

Doomsday Tech

Doomsday threats range from very real (nuclear arsenals) to controversial (global warming) to futuristic (nanotechnology, cyborgs, and robots). Despite the Cold War’s end, we live under the shadow of nuclear weapons, arms races, and accidental launches. Next, we stir up a hotter topic–the connection between global warming and fossil fuels–and ask if they’re cooking up a sudden, new Ice Age. And we examine 21st-century technologies that typify the dual-edged sword of EM Doomsday Tech /EM with massive potential for both creation and destruction–nanotechnology (engineering on a tiny scale), robotics, and cybernetics. We witness amazing applications in the works, wonder at the limitless promise, and hear warnings of a possible nano-doomsday, with tiny, out-of-control machines devouring everything around them.

More Doomsday Tech

The second deadly hour examines more threats–both natural and manmade–that may endanger civilization. From the far reaches of space to tiny viruses, doomsday sources are many. But so are technologies used to keep doomsday at bay. Asteroids of significant size have hit our planet before and likely will again. Asteroid hunters demonstrate the Near Earth Asteroid Tracking (NEAT) program and methods being developed to destroy earth-aimed asteroids. Then, it's onto bioterrorism's sinister technologies–how highly virulent agents like smallpox and plague can be weaponized. Next, an ex-hacker turned cyber-security expert shows how vulnerable the nation's computers are to cyberterror. Finally, we visit the controversial world of biotechnology. Could genetically engineered crops backfire? Does a brave new world of genetically selected beings loom in our not-so-distant future?
