As Atlantis completes its 135th and final mission, this definitive documentary charts the rise and fall of the most ambitious space programme ever undertaken: the space shuttle. For the three decades since its first launch in 1981, the shuttle has become an iconic symbol of America's technological dominance and has rewritten the rules of space travel. It's a reusable vehicle that could lift off like a rocket, carry people and cargo into Earth's orbit, then land on a runway like a plane, and do it time after time. But two disasters, in 1986 and 2003, and the tragic loss of 14 astronauts shocked the World, and signalled the end of the programme and of an era. However, its legacy has been extraordinary.
