I like Feynman, but this bit of theater is virtually the only thing
anyone remembers about the Challenger investigation.  A much richer and
more interesting, and more disturbing, source of information about the
events and the aftermath is the book by Thiokol engineer Allan McDonald
and space historian James Hansen (Truth, Lies, and O-Rings: Inside the
Space Shuttle Challenger Disaster, University Press of Florida, 2009).
