Come in for a smooth landing as we explore the history of hangars--stark, massive structures that house and protect flight vehicles. We visit the first hangar, built on a German lake; Boeing's Delta 4 rocket hangar; Hangar Number One in Lakehurst, New Jersey, that housed all US airships built in the 1920s and '30s; and the Space Shuttle's hangar--as big as four skyscrapers! Back in Germany, Cargolifter's mammoth hangar, large enough to enclose the Superdome, signals the rebirth of an industry.

Welcome aboard the luxury liner Titanic, the world's largest ship and pride of the White Star Line. Watertight compartments and a steel-plated hull render it all but unsinkable. Nearly every technological breakthrough of the previous 50 years is employed onboard, providing comfort and safety for passengers and crew. But none of this will matter on April 15, 1912, when the ship bears down on an iceberg on her maiden voyage, sinking within hours with more than 1,500 lives lost. Learn the details of her construction and how the achievements of technology may have masked her vulnerabilities.

If the long journeys prove successful, all should be hard at work on the Red Planet's surface by January 2004. NASA's Spirit and Opportunity and the European Space Agency's Beagle 2 represent the pinnacle in the history of the search for extraterrestrial life. Leading scientists, who believe life may exist beyond Earth, explain skepticism about ETs having visited Earth.

These extreme aircraft have made their mark on aeronautical history, and sometimes on political history as well. The U-2 and SR-71 spy planes played a crucial role in the Cold War, and now Lockheed Martin's top-secret "Skunkworks" division is touting the new "air dominance" fighter plane-- the F/A-22 Raptor.

Examine the colorful history of the premier flight test center, and America's most important aviation facility for more than 60 years, Edwards Air Force Base in California. Every single aircraft to enter the Air Force's inventory has been put through its paces at Edwards, along with many Navy and Army aircraft as well. With unprecedented access to several forgotten and abandoned facilities on the base, we are guided by Richard Hallion, former chief historian for the US Air Force. Today, Edwards continues to push the envelope. Among the many cutting-edge projects currently being tested is the Airborne Laser, designed to focus a basketball-sized spot of intense heat that could destroy a ballistic missile.

The history of civilization has been built on the back of brick, and it's been said that "architecture itself began when two bricks were put together well." From great Egyptian temples to the Roman aqueducts, the Great Wall of China, and the dome of the Hagia Sophia, brick is one of the oldest, yet least celebrated, building materials manufactured by man. In this hard-packed episode, we explore brick's past, highlighting defining moments, such as the Great London Fire of 1666, the zenith years of brick in the New York Hudson River Valley, and brick as an essential building block in infrastructure and industry. We'll feature advancements through the ages as well as construction techniques, trends, and the future of brick construction. Essentially, brick is still just burnt clay...it has been around for thousands of years, but continues to serve as the backdrop of the modern age.

Journey underground and backstage at the technological marvel that is Walt Disney World. Enter a make-believe world spanning some 27,000 acres, brought to life by cutting-edge technology. What was once Florida swampland now boasts the world's largest theme park. The ride technology ranges from space-age centrifuges to enhanced motion vehicles powered by 3,000 PSI of hydraulic pressure. And hundreds of audio animatronics brought to life through the power of pneumatics, hydraulics, and electrical systems. Walt Disney World is made up of four separate theme parks, each with its own innovations: the 107-acre Magic Kingdom, Epcot, Disney-MGM Studios, and Disney's Animal Kingdom. The four parks are all part of a megaplex of a resort. Twice the size of Manhattan, it was the final vision and crowning achievement of a man who spent more than 40 years pushing the limits of technology to create entertainment magic: Walt Disney.

501 :13x12 - Leather

First aired: Mar/08/2006

Sometime at the dawn of civilization, animal hides were rubbed down with animal fat, making them more flexible, durable, and malleable. By the 5th Century BC, this "tanning" process expanded to include vegetable and tree oil washes, creating what's now known as "leather"--one of man's most reliable and versatile products. Without advances in leather shoes, the Romans could never have marched to the Tigris; nor could the Pilgrims have survived winters in Plymouth. Today, leather is a staple of our daily lives. Modern tanners have devised techniques to make leather more versatile, colorful, and luxurious than ever. We visit modern tanneries of conventional cowhide leather, and explore the more exotic leathers made from alligator, snakes, and even sting-ray. And we'll examine the race of modern science to create synthetic leathers that are supposedly more convenient in today's fast-paced life. We'll see how leather binds us to the past in an unparalleled way.
