HISTORY VAULT

Engineers work to save cities across the globe from the potential effects of super storms and rising sea levels.

Project Impossible

Sinking Cities

A new generation of epic engineering projects; projects that were considered unthinkable just a few years ago are now a possibility with recent advances in engineering and technology.

Unsolved Mysteries

As humans push even further into the world's most extreme environments, a new breed of tools, like a polar survival suit, allow us to go even further.

Man vs. Nature

Scientists all over the world work to keep the lights on as energy consumption continues to increase.

Above the Arctic Circle, a number of projects are underway that will open the Arctic to the rest of the world.

Conquering the Arctic

Structures are being built below the ground's surface which rival skyscraper size.

Digging Deeper

Stories on some the biggest breakthroughs in engineering, from the fastest production bike ever created, to a train with the potential to break the speed of sound.

Biggest Engineering Breakthroughs

A casino explosion; a silo collapses; how chemical weapons are rendered harmless.

Dangerous Demolition

Exploring a new generation of epic engineering projects, projects that were considered unthinkable just a few years ago, but with recent advances in engineering and technology, have become possible.

Engineering America

Builders tackle unique challenges and elevate engineering to new heights, constructing super structures such as Los Angeles' Wilshire Grand Center, France's ITER, Atlanta's Mercedes Benz Stadium, and the Bayonne Bridge in New York and New Jersey.

Super Structures

It is sometimes necessary to create large "super structures" to overcome nearly-impossible challenges. This series showcases the construction of some of these larger-than-life structures. Some of the buildings are constructed to be able to survive natural disasters, while the purpose of others is mainly to highlight what engineers are capable of creating. Among the structures featured on "Project Impossible" are the largest movable building in history and a skyscraper built to withstand major earthquakes.
