Through their superlative buildings, the legacy of the Egyptian empire continues to enthrall people to this day. Yet these incredible structures were made over 4,000 years ago.

When the space shuttle Challenger blew up in 1986, it was the most shocking event in the history of American spaceflight. The deaths of seven astronauts, including the first teacher in space Christa McAuliffe, were watched live on television by millions of viewers. But what was more shocking was that the cause of the disaster might never be uncovered. The Challenger is the story of how Richard Feynman, one of America's most famous scientists, helped to discover the cause of a tragedy that stunned America.

This episode follows engineers building London\'s brand new underground railway, Crossrail, as they take on a Great British obsession - building train tunnels under water.

A team battles to put together the giant jigsaw that will become a cathedral-sized station at Canary Wharf. It\\\'s so big, they have to build it in a dock and underwater. Its architect-designed roof is so complicated it comes in a kit of over 2,500 pieces.

With exclusive access, this returning series follows the construction workers of Crossrail as they battle to finish the final stages of the new Elizabeth Line underground railway beneath the streets of London.

Final part of an exclusive series following the construction of Crossrail - one of Europe’s largest projects and one of the most ambitious in Britain since the time of Brunel.

Following workers across the capital for three years as they race to build an enormous super sewer on time and on budget.

London's Victorian sewer network is at bursting point. Its tunnels are regularly pushed past their limit, and each week the equivalent of 300 Olympic swimming pools full of raw sewage is released into the Thames, totalling 39 million tonnes every year. Now a huge engineering project is underway to massively expand the capital's capacity to deal with its own waste.

In this second episode, construction begins in the heart of London. Two key connection shafts along the Thames are to be dug to enable the super-sewer to be built. In Battersea, a challenging construction technique called 'diaphragm-walling' is employed to build a massive 90-metre-deep shaft.

Examining the inventions that led to the electrical, the transport and the communication revolutions that shaped the modern world.

We take our ability to travel quickly and safely across the globe for granted. This episode reveals the fascinating chain of events that made such everyday marvels possible, telling the story of the handful of extraordinary inventors and inventions who helped build the modern world by making the miracle of powered transport mundane.

Documentary celebrating the 50th anniversary of the first satellite, Sputnik, which launched the space age in 1957. The film explores how satellites have affected almost every aspect of our lives, from spy satellites and GPS transforming the military to the communications revolution kickstarted by Telstar. But recent events in China have revealed just how vulnerable we might be, for they suggest we might be on the verge of another new age, one of satellite terrorism.

At the heart of Britain sits something so all pervasive we don't even notice it's there - the national electricity grid. This three-part series charts how our lives got wired and the impact electrification has had.

Miners, nuclear scientists, politicians, environmentalists and even the City have all wrestled for control of the national electricity grid and the power that it has brought.

In 2011, after more than 30 years of service, America's space shuttle took to the skies for the last time. Its story has been characterised by incredible triumphs, but blighted by devastating tragedies - and the BBC and Horizon have chronicled every step of its career.

The story of The Shard - the colossal glass skyscraper that has transformed London's skyline.

The surprising story of the hidden powerhouse behind the globalised world - the diesel engine, a 19th-century invention that has become indispensable to the 21st century.

Professor Jeremy Black examines one of the most extraordinary periods in British history: the Industrial Revolution. He explains the unique economic, social and political conditions that by the 19th century, led to Britain becoming the richest, most powerful nation on Earth. It was a time that transformed the way people think, work and play forever.
