To transmit microwaves across the Atlantic Ocean, however, it was necessary to establish a single relay tower at least 400 miles high, or station ships every 30 miles, all the way across the ocean. Before the space age arrived, the 400-mile-high tower seemed to be as unlikely a prospect as the spectacle of 100 communications-relay ships strung out across the ocean. That possibility that a very high tower could be established by launching an orbital satellite was suggested first by the British science writer Arthur C. Clarke in an article, '*Extra-Terrestrial Relays," in Wireless World m October 1945. Nine years later, JohnR.
