The steel panels used by Behlen Manufacturing, of Columbus, Nebraska, in the construction of their buildings proved their durability in an atomic bomb test at Yucca Flats, Nevada, on May 5, 1955. Exposed to a thirty-kiloton blast alongside two competitors' metal buildings, two Behlen buildings were the sole survivors still in serviceable condition. Both were returned to Nebraska to be exhibited, one at the state fair and later at the factory, and the other on the University of Nebraska-Lincoln east campus.
To stock bomb shelters with food in the event of a nuclear attack, the Nebraska Department of Agriculture developed "Nebraskits," compressed wheat biscuits formulated to satisfy a person's nutritional needs for at least two weeks. The Division of Nebraska Resources newsletter, Nebraska on the March, sang the praises of Nebraskits: "The rations have a long shelf life, are ready to eat and are palatable to all age groups." The shape was later changed to look more like a conventional cracker, and other varieties were produced.
