It's curious, but I just heard something on French TV from a journalist
that's relevant to this. She said she'd covered the aeronautics field in
the past and mentioned the *principe de dissemblance* (dissimilarity
principle). Critical redundant parts on aircraft, she claimed, would be
sourced from different manufacturers in order to obviate the possibility
of redundant failures you've raised here.
