On September 19

On this day in ...
... 1957 (55 years ago today), the United States conducted its 1st-ever underground nuclear weapon test. Detonated at a Nevada site 65 miles north of Las Vegas was a 1.7-kiloton warhead. This "Rainier" test was one of nearly a thousand nuclear tests that the United States would conduct before halting such testing in 1992. (credit for photo of dust kicked up by test)
