Smithsonian – Stunt – Saturday, 19 February from 4pm

Venture on a globe-trotting mission to discover the ways in which the world works all around us, featuring episodes of:

HOW DID THEY BUILD THAT? – Across the globe, radical architects, ingenious engineers, and skilled builders are creating structures so outrageous, they defy logic and often even gravity. From a Manhattan skyscraper that looks like a Jenga tower to a Singapore glass dome big enough to house a mountain to a high rise in Italy with a built-in forest, we examine the world’s most extraordinary buildings, bridges, and lifts, reveal their design secrets, and discover the incredible stories of their construction.

IMPOSSIBLE REPAIRS – A high-risk/high-reward heli-logging job aboard a chopper that can haul 48,000 tons a mission. A refurbished military vessel that is the heart and soul of a massive open ocean fish farm operation. A freight run that pulls over 50 million tons of cargo a year through Europe. On land, sea, and air, mind-blowing machines are making do-or-die deliveries. Meet the engineers, technicians, and maintenance teams who prep these jobs, complete the repairs, and fix the problems to keep the monster vehicles running.
