SUPER COPTERS
Since their breakthrough invention decades after the aeroplane, helicopters have been used for surveillance, rescue and as a weapon of war. They can seemingly defy gravity, fly backwards, and even fly upside down. But they can also spin out of control and crash - brought down by gusty winds, high altitude thin air and bullets. Using live action, re-creations, amazing archival footage and advanced CGI, we marvel at the creation of today's ‘super choppers’.

SUPER RIGS
Engineers push the limits of design and technology to create the most advanced offshore oil rigs on the planet: thousands of tons of floating steel, structures half as tall as the Empire State Building, isolated on the frontlines of the world's deepest and most unforgiving waters. As the world's insatiable need for oil and gas grows, companies are going deeper, in more hostile environments than ever before. In this new program we rip apart the largest oil rigs on the planet to reveal the secrets of these amazing technological achievements.

SUPER SUB
Super Sub deconstructs a mystery machine that few of us have seen up close – and even fewer fully understand. Focusing on the latest-generation submarine, the USS Texas, we tells the story of this incredible invention. Through exclusive access to training missions, CGI and recreation, we’ll show how today’s submarines defy the imagination: they dive deeper, are quieter (and deadlier), and are capable of feats that would amaze even science fiction writers. Less «
