My knee-jerk reaction to that is to think about the large iron meteorites
in our collections. They tend to be the most competent and coherent and
hence will hold together on impact. It doesn't seem likely to me that an
iron will disintegrate in the fashion you are talking about on impact. I'm
not sure of that, just my first reaction to the statement.
