This eyewitness account describes the atomic missions, the preparation needed for their success, and their aftermath. Told by Charles Sweeney, the only pilot who flew on both atomic missions, it includes sections on the months of careful planning and training leading to the drops, the secrecy, the problems the crew encountered, the final tense seconds, and the reactions after the bombs were dropped. The book contains many personal reminiscences and recollections of both missions, and describes Sweeney’s dealings with important military men involved in the flights, including Colonel Tibbets, pilot of the plane that dropped the atomic bomb on Hiroshima.
