Roger Boisjoly was a booster rocket engineer at NASA contractor Morton Thiokol in Utah in January, 1986, when he and four colleagues became embroiled in the fatal decision to launch the Space Shuttle Challenger.

Boisjoly was also one of two confidential sources quoted by NPR three weeks later in the first detailed report about the Challenger launch decision, and the stiff resistance by Boisjoly and other Thiokol engineers.

According to the libertarian social scientist Charles Murray, America is "coming apart at the seams." Class strain has cleaved society into two groups, he argues in his new book Coming Apart: The State of White America, 1960-2010: an upper class, defined by educational attainment, and a new lower class, characterized by the lack of it.
