Operation Crosstie

From Wikipedia, the free encyclopedia

Operation Crosstie was a series of thirty-three nuclear tests mostly conducted in Nevada during 1967 and 1968. These tests followed the Latchkey series and preceded Bowline.

The blast designated Gasbuggy involved an underground detonation, intended to stimulate production of natural gas by cracking the rock in the underground formation of its deposit. The test was a double-failure, as not only the production did not increase as much as expected, but the customers also refused to buy gas contaminated with traces of radioisotopes. However, the detonation happened mostly as desired.

The individual tests of this series were:
