>From Michael Davis' article Thinking Like an Engineer: the Place of a Code of
Ethics in the Practice of a Profession, Philosophy and Public Affairs, Spring
1991, Vol. 20 #2:
Lund's [the engineer who expressed concern about the Challenger's O-rings]
first response was to repeat his objections. But then Mason said
something that made him think again. Mason asked him to THINK LIKE A
MANAGER INSTEAD OF AN ENGINEER (the exact words seemed to have been take
off your engineering hat and put on your management hat.) Lund did and
changed his mind. The next morning the shuttle exploded, killing all aboard.
An O-ring had failed.
