The Sedan test [1], part of Project Plowshare, was an underground test in Nevada that sent fallout across a large swath of the U.S. Midwaste, sorry, Midwest.

The wife's family lived in Omaha, Nebraska at the time. A lot of cancer in her family. But then a lot of smokers as well. So who knows.

Regardless, that one was a major fuck-up that seems to have kind of put the kibosh on "underground" testing of that sort.
