[SystemSafety] Feynman and the Challenger disaster

[Gergely Buday]

Hi,

I came across this today:

"A fascinating 1986 text by Richard Feynman on the question of how to
estimate the reliability of a space shuttle. This text was written as
part of an investigation of the Challenger launch disaster. It
describes a large mismatch between the reliability estimates made by
the engineers (of the order of 1 failure in 100 uses) and the
reliability estimates communicated to the public by the NASA
management (of the order of 1 failure in 100 000 uses). I think this
text should be of interest to anyone interested in security,
engineering, the production of safety-critical products and its
management."
