Blowdown (TV series)

Blowdown is an internationally broadcast documentary television series that follows a team of explosive demolition experts as they prepare and implode iconic, complex and challenging structures around the world.

The series airs on National Geographic Channel International, History Television in Canada, DMAX in Germany and Five in the United Kingdom, and is produced by Parallax Film Productions Inc..

The hour-long shows focus on the dangers, challenges, and inside strategies of this high-risk type of demolition by documenting the work of a specialized explosives team: Controlled Demolition Incorporated of Phoenix, Maryland, USA.

Using a combination of exclusive footage, high-concept visual effects and process-driven computer models, Blowdown explains the complex science behind CDI’s mission.

The series highlights obstacles the team encounters as they rely on experience and intuition to reverse engineer structures designed to be indestructible.
