NEVADA TEST SITE

This photograph was made at a firing area in Yucca Flat, Nevada Test Site, the morning of January 30, 1957. As Nevada Test Organization and Sandia Laboratory personnel began a series of experiments to determine if anchored balloons may be used as detonation platforms for full scale nuclear tests. The tube like extension of the balloon (lower right) is used to inflate it with helium.
