We don't know what the workplace situation was there.  So we don't know
such discussions did occur, or if they were greatly discouraged by the 
powers that be a.k.a the Challenger space shuttle incident, the quashed 
opinions of some low level NASA scientists that did not agree with
high level political power philosophies, and the employment at will 
doctrine.  The more money and political power that's involved, the more 
likely that these are some of the important underlying issues.

Me, I sincerely doubt that anyone talked that much about it, any more
than they would have intense discussions about a bolt.

It's rather disconcerting to realize that much work is being done by
young (and therefore inexpensive) structural engineers without a lot of
experience, and that they aren't monitored that much.

This has been my experience over the years when I've consulted on
forensic projects.
