ARMY RENEWS STUDY OF BOMB BLASTS.

The article reports that army engineers are resuming a project to test the effects of bombs on underground structures such as shelters and industrial plants constructed in caves. The tests will attempt to determine the types of material, which will provide the best protective covering for underground installations. It will be conducted at testing sites in Utah, Colorado and New Mexico. Results of the bomb-penetration tests will be passed on to civil defense planners. The U.S. Army is also considering plans for two typical underground industrial plants.
