PBS special 'The Bomb' seeks to tell story of atomic weapons for 70th anniversary

A new PBS special looks into the creation of the atomic bomb at the then-secret city of Los Alamos and will feature newly restored and declassified footage.

"The Bomb," which begins airing this week on most PBS stations, seeks to tell the story of nuclear weapons as the 70th anniversary of the atomic bombings of Hiroshima and Nagasaki approaches.

Producers say some of the footage of the film has been declassified only recently by the U.S. Department of Defense.

The first test took place in southern New Mexico as part of the Manhattan Project, the secretive World War II program that provided enriched uranium for the atomic bomb.

The project involved three research and production facilities: Los Alamos; Oak Ridge, Tennessee; and Hanford, Washington.
