A cutting-edge engineering marvel, the Falkirk Wheel in central Scotland, can lift boats and water to astonishing heights. Its advanced design makes it the first and only rotating boat lift of its kind. Behind-the-scenes access shows how it works. It reconnects the Forth and Clyde Canal with the Union Canal for the first time since the 1930s, opening in 2002 as part of the Millennium Link project. 

To carry infantry troops to the frontlines, military engineers designed three battlefield behemoths that command the land, sea, and air. Special access reveals how cutting-edge tech made these innovations for the U.S. Air Force (C-17 Globemaster III), Army (Stryker), and Marines (ACV/Amphibious Combat Vehicle) possible.

Engineers in China are constructing the largest and most ambitious water transfer project in human history, defying nature to move vast quantities of water from the south to the dry north in Beijing, all without the use of pumping stations. This is China's South to North Water Diversion Project.
 

Test pilots and engineers embark on the first flight of the largest airplane ever built: the Stratolaunch, a one-of-a-kind aircraft designed to transport rockets, spacecraft and experimental hypersonic planes into the stratosphere.
