Wgtd's The Morning Show With Greg Berg

From 2015 comes a conversation with Neil Swidey, author of "Trapped under the Sea: One Engineering Marvel, 5 Men, and a Disaster 10 Miles into the Darkness."  It chronicles the efforts in Boston to construct a huge tunnel beneath Boston Harbor that would allow the city to discharge waste well out to sea rather than directly into the harbor.   It was an engineering project of enormous complexity- and, regrettably, it resulted in the deaths of two of the five divers involved in the most dangerous phase of the construction.
