It is perhaps sad, but I&#x27;m heartened by this letter.  I had heard that warnings were given in advance, but this is clear (in fact, I find the &quot;catastrophe of the highest order&quot; language to be less impressive than the clear and defined &quot;loss of human life&quot;).<p>Why am I heartened to see that someone foresaw a lethal accident and was ignored?  Because it was foreseen, and the consequences understood, with clarity.  Getting people to take clear warnings seriously seems a more easily solved problem than getting us to be able to recognize the danger in the first place.  A single person in management, or a few people, being dense is fixable.  Groupthink where everyone assumes someone else is checking for problems and no one does is harder to fix.<p>Now, just because it&#x27;s an easier problem doesn&#x27;t make it an EASY problem, but still, easier.
