Mannequins seated at a table in the dining room of house number two, attend a "dinner party" thrown by Civil Defense officials that are testing the effects of an atomic explosion on houses and occupants on March 15, 1953. The first in a series will be held at the atomic proving grounds near Las Vegas, Nev. No one knows what will happen when the bomb goes off a mile and a half away, but officials hope most of this will remain standing. (AP Photo/Dick Strobel) Dick Strobel
