Discovery Channel Extreme Engineering - Tokyo's Sky City

With land area shrinking and population growing, Japan has decided to take its urban development strategy to the next level. Welcome to Sky City – the most massive super-building on earth and certainly one of the most daring feats of engineering ever attempted.

With its 14 steel, concrete and glass 'plateaus,' each 40 stories high and stacked on top of each other, Sky City will rise a full mile into space – more than twice the height of any existing building! The towering, vertical city will house more than 100,000 people and provide for every aspect of modern life with parks, schools, homes, offices and shops all housed within the 'city's' ample walls.

Only one problem: No one knows for sure if it can really be built! Join leading engineers from Japan, Taiwan and Canada as they try to tackle the immense mechanical, structural and logistical issues behind such an enormous project. Architects have drawn up plans for a truly majestic edifice, but can they protect the city from earthquakes, typhoons and the very worst disaster that can strike a tall building – a raging inferno?
