Re: Why such a crude method?
I remember a novel plot point in a spy book I read many years ago, possibly the 80's. The spy would go outside at certain specified times, lay on his back and then mouth the words of the information he needed to pass on. The timing was critical because the spy satellite passing over would be filming him for the lip-readers back home.
Now that I've typed that out, ISTR it was an SF book, but set in the present or at least very near present day (of the time, not 21st C)
