This edition of Narrative features an interview from StoryCorps, an oral history project that collects the voice of our time. At the StoryCorps mobile booth in Columbia in 2016, Dean Byrd talked with his father Willard Byrd, a veteran of the Korean War. Willard had a unique role with the army. He was stationed in the Marshall Islands, where he worked as a machinist. He was also witness to something few people have seen. Here, Dean Byrd asks his dad to tell the story of seeing the first test of a Hydrogen Bomb, known as Ivy Mike, on November 1, 1952.
