On December 6, 1994, the museum completed a script for a supplementary segment to be placed at the beginning of the exhibition. Despite negotiations over content and presentation with both the Air Force Association and the American Legion, each version of the script was met with severe criticism. Three additional revised scripts were drafted between late August and late October 1994. On May 31, 1994, the new version, retitled "The Last Act: The Atomic Bomb and the End of World War II," was completed. Under pressure from both organized groups and the general public, the National Air and Space Museum began revising the script. Correll also noted that the script warns that "parental discretion is advised." He argued that this was not the objective setting that many World War II veterans envisioned when they petitioned for the display of the historic aircraft. Correll, Editor-in-Chief of Air Force Magazine, a publication of the Air Force Association, wrote that "many visitors may be taken aback by what they see" and "the presentation is designed for shock effect." He detailed the plans in the script to include images of melted and carbonized objects along with life-size photographs of victims and words of survivors recalling the horror of the bombs.
The Air Force Association publicly responded to the script on March 15, 1994. What Harwit and the curators saw as a balanced history of the bombings and their consequences, many interpreted the script as a depiction of vengeful Americans and an attempt to garner sympathy for the Japanese. For many, the script only confirmed those fears. Many veterans had advocated for the display of the Enola Gay, the B-29 Superfortress used to drop the bombs, as a celebration of American triumph over Japan, but there were already concerns that the Smithsonian was creating a politically correct, revisionist interpretation of the events. Once complete, he sent the script to the group for comment. Plans for the exhibition began as early as 1987, and Harwit had already been in discussions with the Air Force Association while the script was under development.
The original script, completed on January 14, 1994, contained five sections: "A Fight to the Finish," depicting the last year of World War II "The Decision to Drop the Bomb," raising questions about the need to use nuclear weapons against Japan "The World's First Atomic Strike Force," illuminating the experiences of the bomber pilots "Cities at War" describing ground zero and "The Legacy of Hiroshima and Nagasaki," discussing the beginning of the arms race and the Cold War. In the years leading up to the 50 th anniversary of these attacks, National Air and Space Museum director Martin Harwit and curators Tom Crouch and Michael Neufeld imagined an exhibition that would provide a balanced look at the bombings. The United States dropped an atomic bomb on Hiroshima on August 6, 1945, and another on Nagasaki three days later. In 1994, the National Air and Space Museum completed an exhibition script titled “The Crossroads: The End of World War II, the Atomic Bomb, and the Origins of the Cold War.” Over the next year, this script, and the versions following it, would generate one of the greatest controversies the Smithsonian ever experienced.
