[TowerTalk] Tower Collapse in South Dakota

I think ham radio tower installations have far too unpredictable 
potential failure modes to make generalizations.  Many are short enough 
to be relatively stiff and would tend to lay down in the case of a 
failed guy.  Some are overloaded and/or vulnerable to twisting, which 
would tend to bring them down in a heap.  Others are poorly maintained 
and could fail in all sorts of ways.  The results could be different in 
every case, and I've seen pictures of several of them.  If I was making 
rules for private tower installations I'd require that set back as well.
