Again, I'm no structural engineer, but I would think that falling
straight out would be indication of an abnormal situation. It seems
that if it were properly guyed (with proper strength guys at each
point), it would fold, because the remaining guys would pull toward the
center. On the other hand, if a complete anchor failed, it's going to
have a tendency to lay over full length.
