When I was in elementary school a national magazine did an article on what would happen if a hydrogen bomb were dropped on Detroit. I don’t remember all the details, except that windows would have been broken in Lansing, and where I lived would have been melted glass. This was back in the early 1960s, when we were still tucking ourselves under our desks in that famous “duck and cover” air raid drill.
I wasn’t terribly sophisticated, but I was smart enough to figure out that squatting under a Formica desk wasn’t likely to save anyone. After the Cuban missile crisis, I read portions of a book I was probably too young for, Herman Kahn’s On Thermonuclear War.
