Returning to weapons research when President Kennedy ordered resumption of underground testing in Nevada, Ogle was recommended for the Christmas Island job by his longtime boss, Alvin Graves, test director at Los Alamos. (Graves has been one of the leading figures in nuclear testing, once was critically ill from exposure to a radiation dose of 200 roentgens; he recovered, but has been slowed down since...

Some of the depressions are only a few feet deep, but two of them are 50 ft. deep and several hundred feet across. The holes are not craters; nothing is blown out. There is no radioactivitiy, and the level of the ground around the depressions is not raised. But millions of cubic feet of dirt have...
Last week the AEC explained that recent bomb tests have been conducted in deep vertical shafts. The walls of the test chambers are of sedimentary strata full of small pores. The irresistible pressure of a bomb's expanding fireball compresses this material, forming a spherical cavity holds its shape for 15-25 minutes; then the cooling gases lose their pressure.
