Impossible Engineering - Season 10

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.
