A-Bombs for Peace.

Throughout the 1960s, the Atomic Energy Commission (AEC) pursued a series of projects called the Plowshares Program, an attempt to find peaceful uses for atomic bombs. In 1961 the first peaceful nuclear blast occurred. It was detonated under-ground twenty-five miles from New Mexico's Carlsbad caverns. The purpose of Project Gnome was to conduct various scientific experiments; the explosion was expected to supply a vast underground salt cavern and to produce steam for generating electricity. The blast occurred pre-maturely, and the explosion knocked the top off the underground chamber, ruining the steam "teakettle" and letting clouds of radioactive waste into the atmosphere. Gophers chewed through cables connecting some of the scientific instruments. Nonetheless, the scientists present declared Project Gnome a great success.
