Impossible Engineering

The largest semi-submersible crane vessel in the world, the SSCV Sleipnir, pushes the limits of engineering possibilities; with its two record-breaking cranes, it's one of the most complex ships ever constructed and redefines how we build at sea.

The Rosalind Franklin ExoMars rover is a brand-new space mission by the European Space Agency (ESA) to discover hard evidence of extraterrestrial life; special access reveals how engineers and experts are making a new age in exploration possible.

The deepest-diving submersible vessel in the world, the Triton 36000/2 (aka DSV Limiting Factor ), is one of the most intricately designed crafts ever engineered for the sea. Having reached the bottom of each of the five oceans and certified "Depth: Unlimited," this submarine's accomplishments are truly monumental.

The abandoned Battersea Power Station on the banks of the River Thames is being reinvented into a stunning centerpiece of London; now, experts use cutting-edge construction techniques to transform this historic landmark into a pioneering new destination.

The Global Supertanker is the largest firefighting aircraft in the world and equipped to reach the biggest blazes anywhere; expert engineers reveal how this game-changing machine is a vital tool for supporting heroic firefighters on the ground.

The Singapore National Stadium is a gigantic multipurpose arena that all sits under the world's largest free-spanning dome; expert engineers reveal how this cutting-edge design marks the dawn of a new age in superstructure construction.

The largest helicopter in the U.S. military arsenal, CH-53E Super Stallion, has completely redefined the capabilities of heavy-lift aircraft; using the latest in cutting-edge engineering, it can transport vast amounts of cargo and personnel, all while under enemy fire.

The US military's most advanced hovercraft, Ship-to-Shore Connector (SSC), represents the next generation of amphibious transport vehicles; using the latest in cutting-edge tech, it's designed to carry the heaviest cargo into locations that were previously impossible to reach.

The Queensferry Crossing in Scotland is the longest triple tower cable-stayed bridge in the world, and with record-breaking underwater foundations, it stretches the limits of engineering possibilities and marks a new age of superstructure construction.

The V-22 Osprey is a revolutionary feat of aviation engineering that combines the speed and range of an airplane with the landing versatility of a helicopter, allowing the US military to transport troops and cargo into seemingly impossible locations.
