Impossible Engineering - Season 7

The man-made islands of Dubai are modern-day engineering marvels that turn the Persian Gulf into high-priced real estate, and today, a team of expert engineers uses cutting-edge technology to build a brand-new city district where there was once only water. This is Bluewaters Island, a lifestyle destination featuring distinctive residential, retail, hospitality, and entertainment options. It includes the Ain Dubai, or Dubai Eye, the world's largest observation wheel at 689 feet tall. 

A team of engineers is overhauling London's underground infrastructure to build a world-class super-sewer system, the Thames Tideway Tunnel. Using cutting-edge tech and the latest construction methods, they work to transform a centuries-old network into a modern-day masterpiece. 

The F-35 is the most advanced fighter jet on the planet, and special access into the most expensive military program ever reveals how engineers use cutting-edge technology to outfit this 1,200 mile-per-hour aircraft with a state-of-the-art stealth system.

The skinniest skyscraper in the world will soon become New York's third tallest, and using an innovative, gravity-defying design, this colossal megastructure is breaking all the rules of engineering. 111 West 57th Street, or the Steinway Tower, is an 84-story, 1,428-foot (435-meter) supertall residential project. 
 

Engineers are racing against the clock to build the world's biggest airport, Beijing Daxing International Airport. Using cutting-edge construction methods, experts put the finishing touches on a modern-day marvel that will move 100 million people in and out of Beijing every year.

A state-of-the-art NATO airplane, the Airborne Warning and Control System (AWACS), is one of the most complex surveillance tools in the world, and special access inside this behemoth reveals how cutting-edge engineering and a hi-tech midair refueling system helps its crew defend against security threats.

The world's highest bridge, China's Beipanjiang First Bridge, impossibly spans an 1,854-foot chasm known as the Crack in the Earth, and to build this engineering marvel, experts use cutting-edge construction technology that can conquer the deadly cliffs of this rugged environment.

Deadly avalanches and catastrophic flooding are ever-present threats at Whistler, British Columbia, Canada, one of the world's busiest ski resorts. New technology and cutting-edge construction methods help engineers conquer the elements to keep this mountain-top getaway safe.
