Tom Ferebee, top photo left, the bombadier who dropped the first atomic bomb on Hiroshima, talks with Sgt. Roy E. Fagan, right, after signing a poster of the Enola Gay, the plane that carried the bomb. Fagan was the first to photograph Hiroshima and Nagasaki after the dropping of the atomic bombs. Using a hand-held camera, Fagan shot his pictures of the devastated cities through the glass window of the cockpit. Some of the original prints were on display at the Exposition. The bottom photograph shows war protesters from the Des Moines Catholic Worker Community standing outside the admission area during the Aviation Expo in Ankeny, protesting what they thought was a “sugar-coated” treatment of the bombing.
