Those are interesting numbers.  I didn't know they existed.  However, I
would have to say that they cover the only one I have had direct
exposure to.  In that case, the 1500' tower folded itself into a radius
of about 300 feet of the base when a top guy failed while iced up.

I would NEVER consider that to be a "norm", but maybe it is.  I
certainly wouldn't bet my life on it.
