An explosive demolition team is challenged with safely imploding complex and iconic structures around the world. Each episode focuses on the dangers, challenges, and inside strategies of this type of high-risk demolition. Built to withstand time, gravity and natural disasters, every job poses unique engineering challenges. Blowdown premieres on Wednesday 20 October at 9pm and explains the complex science behind the missions and highlights obstacles these experts encounter as they rely on experience and intuition to reverse engineer structures designed to be indestructible.

The team is faced with an engineering marvel gone horribly wrong in the first episode as they deal with their strangest challenge yet: to demolish a brand new hurricane-proof tower. In the second show they're faced with the demolition of a 60,000-seater super dome which sits a few metres away from a multimillion dollar convention centre and a main rail line. And in an unprecedented demo job the Blowdown crew joins forces with marine salvage specialists to turn a 17,000-tonne former spy ship into the second-largest artificial reef in the world. Will they give this dead vessel a new life? Or will the sink plan lead them to disaster?
