The Glass Skyscraper

The Black Pearl is one of the largest and fastest sailing yachts in the world, and using cutting-edge innovations in shipbuilding and engineering, its crew puts this brand-new $200 million vessel through the gauntlet to test its unique capabilities.

When engineers built railroads across the swamps of New Orleans, they used cutting-edge technology and methods to get it done, and these extreme trains attest to the innovative engineering required to conquer the most challenging water environments.

A rugged ship built to withstand tsunami size waves travels on a highway unlike any other in North America. A fleet of machines combats a massive flood in the Arctic Circle. And the biggest, most powerful wind turbines in Alaska.

The Yeti, a machine with 588 sharp teeth, helps keep the coldest airport in America running. Mighty tugboats chew through ice chunks in Alaska. And soldiers become Arctic warriors in the coldest army post in the country.

On the remote island of Sitka, Alaskan engineers construct a giant dam to power the town. Ride on a dangerous mission on the world's largest helicopters. Alaska's biggest boat lift hauls a 400-ton fishing ship in high winds.

Alaska's Coast Guard fights the most dangerous waters in the state to maintain buoys standing three stories tall. Explosive machinery yields big rewards 800 feet below Alaska's surface. An army of Alaskans build a steel ferry, several tons at a time.

A unique barge carries an entire train along Alaska's high seas. A mega fish factory on a remote island churns out 3 million pounds of seafood a day. A flying ambulance saves lives 14,000 feet above Alaska's wilderness.

Only in Alaska can you find an airport made from nothing but water and ice. Hardy vehicles brave the arctic to travel across the tundra. And next to a field of moose, 16 missiles stand by to prevent a nuclear disaster.

At Jimmy’s Junk, inventors are looking for parts to complete what appears to be a jet-propelled merry-go-round. Later, shop regular Hale Storm tries to sell Jimmy an African Birthing Chair and a gigantic piece that could take the yard to new heights.

At Jimmy's Junk, an inventor needs Jimmy to hunt down a replacement engine for his surf cycle prototype. Then, two students hope Jimmy can give their solar-powered tank the firepower it needs to win a creators competition for a prize of $10,000.

At Jimmy’s Junk, things heat up when inventors need help creating a flame cannon and Hale reveals his own balls of fire. And when a team of lawn mower racers need a replacement transmission it’s up to Billy to turn a piece of trash into a trophy win.

At Jimmy’s Junk, inventors need help turning a fridge into a beer launcher, and Hale lands himself in hot water. Later a high school class’s hopes may go crashing into a watery grave when they ask Jimmy to come up with an engine for their hovercraft.

At Jimmy’s Junk, it’s all hands on deck to create a huge new sign for the yard, but when things are just about finished a team member really drops the ball. Later, emotions explode when the guys prank Hale, and Jimmy has a near-death experience.

At Jimmy’s Junk, a team of Punkin Chunkers need Jimmy’s help to take their homemade trebuchet to the next level, and yard regular Hale has found something that he thinks will blow Jimmy away. Then the guys get creative in recycling an old treadmill.

From Steven Spielberg comes the story of Americans rebuilding a 16-acre plot in Lower Manhattan and healing a nation in the process. The new World Trade Center, which will rise 1,776 ft, will embody America's physical response to the 9/11 attacks.

Producer Steven Spielberg presents the new World Trade Center. About to reach the 1000-foot mark, it is effectively reclaiming the New York City skyline. However it's more than just an engineering marvel, it demonstrates that America is rising.
