— In “Electronic Navigators” (October) your Loran position readout on the artwork is given as +30° 17.2’ lat. and -90° 90.6’ long. If we accept the convention that plus latitudes are north of the equator and minus longitudes are east of Greenwich, this places the vessel in the Hsi-Tsang Tzu-Chih-Ch’u Province (Tibetan Autonomous Region) of China. In other words, about 285 miles northeast of Mt. Everest. Who is the skipper? Is there a load of paired animals aboard? What is the vessel’s LOA (in cubits)? Is it raining a lot there? Mo Prophet Nazareth, Pa. Both the CIA and the National Council of Churches are investigating.
