Dembski could argue here that the natural assembling of the first flagellum is not absolutely impossible, only highly improbable. While that might be technically true, the whole of Dembski’s argumentation is dedicated to demonstrating that non-natural action was an essential element in the assembling of the first bacterial flagellum. Under those circumstances, the technical distinction between "naturally impossible" and "possible but so astoundingly improbable as to conclusively preclude natural formation" strikes me as the rhetorical equivalent of attempting to hang a 500-pound painting on the wall with a tailor’s pin.
