The 9/11 Mastermind The bombing of the World Trade Center in 1993 sets off one of the biggest manhunts the world has ever known. The CIA and its intelligence partners around the world follow a chain of evidence from the Philippines to rural Pakistan to capture the man behind the plot: Khalid Sheikh Mohammed, or KSM. The 9/11 Mastermind is a dramatic story of the CIA's quest to find this once-shadowy figure piecing together fragments of intelligence from around the world. But before they can find him, he engineers the biggest terrorist strike on America in history - the attacks of 9/11. Now, the CIA will have to use every trick in its handbook - eavesdropping, satellite imagery, informants and paramilitary undercover ops to hunt down al Qaeda's military leader before it's too late. Teaming up with Pakistani Intelligence and the FBI, the CIA follows a frightening trail of evidence to the ultimate showdown.

Icebreakers: Arctic Giants This episode reveals the engineering breakthroughs behind the Arctic's biggest icebreaking ship — the oil tanker Timofey Guzhenko. Weighing in at over 93 thousand tonnes, the Timofey Guzhenko is by far the biggest icebreaking ship to operate in the Arctic Ocean. It can smash through solid ice a meter and half thick and pulverize blocks of ice the size of a car with its huge propellers. But the Timofey Guzhenko wasn't designed and built in a day. It stands on the shoulders of historic engineering achievements that have allowed it to grow so big. This film charts the stories of four historic inventions, embodied by landmark machines — giants of the ice.

In the year 2210, scientists uncover the ruins of a great civilisation – so powerful one could argue it dwarfed anything that came before it. Sifting through the wreckage of cities overtaken by the desert and swallowed up by the sea, they piece together a remarkable story of collapse – the story of what on Earth happened to us.

World's Fastest Train A look at the mind-blowing engineering breakthroughs that made the TGV possible, including the Japanese bullet train and Stephenson's record-breaking Rocket. Trains are one of the most popular land transportation means. With the development of technology, people can make High Speed Rail that used for fastest train in the world. Several countries in the world are trying to make the fastest train in the world. Some of the trains are still in service but some of them become a failure for the company that invested on the development of the railways.
