# Operation Doorstep

"The effects of an atomic explosion on two average frame houses are shown in Operation Doorstep, film story of the atom firing at Yucca Flats, Nevada during the March 17 civil defense demonstration. Produced by Byron, Inc., in cooperation with the Federal Civil Defense Administration, the film shows the preparation necessary for such a project, and the combined efforts of television, newsreel and radio facilities to bring home to Americans the importance of being prepared in the event of atomic war." This version includes "Prologue to Operation Doorstep," probably produced later and added to main film, and contains many images that have become emblematic of the Cold War-era nuclear weapons testing program. "Effects of Atom Bomb Are Shown in Byron's "Operation Doorstep.""
