World's Most ExtremeSun 27 Sep, Airports

World's Most Extreme is a TV show on Seven. From airports precariously carved into unstable ice shelves, highways built along sheer cliffs, to bridges held together by nothing more than rope, this series counts down the WORLD’S MOST EXTREME airports, railways, roads, tunnels, bridges and waterways. Using first-person eyewitness stories, rare archive and CGI, we throw you into the world’s danger zones. The long-running program has been available since 2014. A total of 4 episodes have been broadcast, most recently in January 2017.
