The 1930s was a highpoint for ocean-going liners. Crossing the Atlantic by boat was the only way to reach the US, and competition between the French and British shipyards was never less than fierce, a focus for patriotic pride.

Back in the 1930s, two giant airlines began to span the globe, flying firstly mail and then passengers around the world. Pan American flew to Latin America and eventually across the Pacific to Asia.

The fourth episode in the series visits the fast, furious and all-too-often deadly powerboat races of the 1920s and 30s.

George Carey's film shows how the Russian space programme was kick-started by a mystic who taught that science would make us immortal, and carried forward by a scientist who believed that we should evolve into super-humans who could leave our overcrowded planet to colonise the universe. Stranger still, Carey shows how those ideas have survived Communism and adapted themselves to the science of the modern world.

Engineer Jem Stansfield looks back through the Horizon archives to find out how scientists have come to understand and manipulate the materials that built the modern world.

The inside story of the James Webb Space Telescope, following the Nasa team building the £8 billion device and the scientists taking its first image of distant stars and galaxies.

Supersized Earth traces the spectacular story of how humans have transformed our world in a generation.

In this final episode, Dallas examines what it takes to keep seven billion humans alive with food, energy and water.

In this episode, Dallas explores how we can travel further and faster than ever before - and how our desire to shrink the world is inspiring some of the most extraordinary engineering projects on the planet.

Supersized Earth traces the spectacular story of how humans have transformed our world in a generation. In this awe-inspiring three-part series, Dallas Campbell travels the globe, visiting the world's largest and most ambitious engineering projects, exploring the power of human ingenuity.

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.

Dan Cruickshank explores the secrets of the bridges that have made London what it is. Along the way, he uncovers stories of the sublime ambition of London's bridge builders.

Series following a team of more than 10,000 engineers and construction workers as they race to build a brand new railway under London - Crossrail - London's new Underground.

Series following a team of more than 10,000 engineers and construction workers as they race to build a brand new railway under London - Crossrail - London\'s new Underground.

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.

London's Victorian sewer network is at bursting point, and now a huge engineering project is underway to massively expand the capital's capacity to deal with its own waste.

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.

Filmed at Claridge's over six years, this series follows work to dig out a five-storey mega-basement, add four new floors and create London’s most exclusive penthouse.

A team of miners work to tunnel under the hotel by hand, while upstairs, hotel manager Eugene tries hard to ensure loyal guests remain undisturbed by the work above and below them.

It's just over halfway through the seven-year renovation project, and the team have adopted unusual measures to make way for the next stage of the audacious build – a four-storey roof extension.

With the shell nearing completion, the hotel turns its attention to the interiors, employing some of the world’s top designers and craftsmen to meet the expectations of their well-heeled guests.

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.
