Only madmen could contain the thought, execute the act, fly the planes. The sane world will always be vulnerable to madmen, because we cannot go where they go to conceive of such things. We could not see it coming. We could not be here before it happened. We could not stop it. But we are here now. You cannot see us for the dust, but we are here. You cannot hear us for the cries, but we are here.
