Behind every seemingly impossible marvel of modern engineering is a cast of historic trailblazers who designed new building techniques, took risks on untested materials and revolutionised their field. Each episode details how giant structures, record-beating buildings, war ships and spacecraft are built and work. As the show revels in these modern day creations, it also leaps back in time to recount the stories of the exceptional engineers whose technological advances made it all possible.
