L'American Way of Life bombardée dans un exercice de sécurité civile.
"Operation Doorstep was a Civil Defense test carried out in conjunction with the much larger March 17, 1953, 16-kiloton ANNIE test conducted at the Nevada Test Site, part of Operation Upshot-Knothole. In the smaller Operation Doorstep test, blast and thermal effects were evaluated on mannequins, automobiles, and wooden frame houses."
