In 1943, a B-25 Mitchell, WWII's most versatile twin-engine bomber, crash-landed in South Carolina. It sank 150 feet to the bottom of a lake and over time was forgotten. Now, 60 years later, a local doctor is determined to raise the giant bomber intact and give it to a museum. Our team--divers, engineers, and preservationists--takes on the job of moving the 20,000-pound bomber to the surface, while faced with the challenges of working in nearly zero-visibility murky waters and the wrath of an approaching hurricane, plus fear that the plane may be breaking apart!

In Pennsylvania, our movers must lift an historic 1938 diner out of a building that has covered it for more than 50 years. But moving the cherished landmark unscathed will pose quite a challenge for everyone involved. Meanwhile, a determined mining historian must rescue a gigantic 1923 steam shovel that has been hidden high up in the Colorado Rockies. Will 30 years of sludge and rugged terrain stop this move before it even begins?

In America's heartland, few structures are as iconic as the country barn and the local church. In Nebraska, our team attempts to transport an historic gothic horse barn to a new farm. Working in sub-zero temperatures, they'll have to maneuver the massive structure through 26 miles of extremely narrow, unpaved country roads to reach their destination. And in Texas, a 115-year-old church has to be cut into five pieces before being relocated to a new spot two miles away. Will our Mega Movers be able to reassemble this cherished chapel and preserve it for future congregations?

Whether it's at the top of a towering skyscraper or at the bottom of the ocean, if it's got to be moved, the Mega Movers are always up to the challenge. In this episode, we look at two very different moves in two extreme environments. In California, the team must disassemble and move a tower crane that soars 36-stories high in the middle of downtown Los Angeles. And in North Carolina they struggle to move a pre Civil War house. See the unique methods and tools that these movers use to get the job done.

Some of the most spectacular Mega Moves in history have taken place through a route unavailable to most movers: the air. In Florida, the crew of one of the world's most unusual looking airplanes will move a piece of the International Space Station to a facility in Alabama. And in Colorado, watch as Russia's largest cargo jets transport sections of the Atlas Satellite Rocket for an upcoming launch. Do these engineers have the right stuff to get the job done? We'll follow the dangerous relocation of these structures--from the planning process to the actual move--where any second can spell disaster.

Bridges have been pushed, airlifted and taken apart, but if needed, can one of the world's longest and most famous suspension bridges be moved? Experts say San Francisco's Golden Gate Bridge can be relocated.

The Denver International Airport is the largest airport in America. Its famous white peaked fabric roof spans a million-and-a-half square feet. Moving it would seem impossible--but not for this crew!

Imagine trying to move a 475,000 pound structure from Texas to Minnesota. Forget freeways, it'll never clear bridges or overpasses. Flight is out of the question.
