Hiroshima nuclear bomb attack: Aerial pictures of Hiroshima taken in April 1945 before the atomic bomb was dropped and, in August 1945 after the bombing, show the extent of the devastation on the city. August 6, 2005 marks the 60th anniversary of the bombing, which instantly killed about 78,000 people. These photos were part of the records of the U.S. Strategic Bombing Survey. Reuters
