The National Geographic Channel EXPLORER series takes on the August 6, 1945, U.S. Air Force atomic bombing of Hiroshima, Japan, in this chronological retelling of the 24 hours following the event.

The atomic bombing of Hiroshima, on August 6, 1945, was a moment that changed the world. Power that fueled the stars had been unleashed and turned into a lethal technology. Now learn the second-by-second story of that defining moment through those hit hardest by that weapon--the survivors.
On August 6th, 1945 a weapon unlike any other before was unleashed on the Japanese city of Hiroshima. Four days later, the Japanese surrendered having been subjected to horrors and devastation previously unknown and unimaginable. But beyond the horror and human toll, real scientific questions remained unanswered. In 1945, a team of scientists and experts from the Manhattan Project was ordered by President Truman to investigate the facts of what really happened when the atomic bomb exploded over Hiroshima. National Geographic reveals the incredible science behind what happened moment by moment in the 24 Hours After Hiroshima.
Narrated by Peter Coyote, 24 HOURS AFTER HIROSHIMA uses re-creations, stock footage, and stories to piece together the act that killed/injured 129,558 people. This comprehensive look back at the catastrophic events leading up to the end of World War II includes first-hand accounts from people such as Enola Gay crew member Dick Jeppson and survivor Takashi Tanemori. Interwoven throughout the survivors' stories, we hear from atomic bomb experts like Massachusetts Institute of Technology Professor Theodore Postol and "The Making of the Atomic Bomb" author Richard Rhodes, who draw from declassified military reports to break down the bomb's devastating effects and the lasting implications of humanity's newfound power to destroy the world.
