Ultimate Explosions

Tiff Needell narrates this documentary about an immense unexploded World War One bomb found under a Belgian farmhouse, the sinister product of an arms race that would eventually lead to Hiroshima and Nagasaki. The programme reveals how a series of tunnels were packed with explosives by the Allies during the conflict in an effort to secure a strategic ridge, but four remained undetonated. One was destroyed by lightning in 1955, harming no-one, and two still exist under open fields : but the shocking discovery that another is now lying under a working farmhouse has forced experts to attempt to resolve the situation before disaster strikes
