No.  As Tufte pointed out, those engineers produced poorly analyzed
chart-junk filled graphs which obscured rather than helped reveal the
meaning in the data.  They could have instead easily produced an
informative graph which would have helped illuminate the known and
very severe risk of O-ring burn through.  They did not, and indeed,
the graphs they DID generate were WORSE than useless.

That was an ENGINEERING failure, and not one that would have been
helped by any class on what is colloquially known as "presentation
skills".  A serious, hard-core treatment of graph and information
design, yes, that could have helped.  "Presentation skills", no.

Exactly.
