The Bermuda (or Devil's) Triangle is that stretch of sea roughly bounded by Bermuda, Florida and Puerto Rico, into which, the Stories go, an ""unusual"" number of planes and sea craft have disappeared ""without a trace."" Kusche is out to spoil the fun of those who see alien beings or Other Dimensions at work -- psychics, ufologists, and that sector of the public pleasantly chilled by the subject, via movie, TV special, articles, and the latest best-selling Berlitz. And this he does, with both a straightforward use of reliable documentation and a sly use of the Triangle ""Legend,"" tremulous parodies of which open each chapter. There are usually logical explanations, Watson, for all the vanishments; and the Triangle buff who uses his scanner on the contents will recognize all the ""cases:"" from the fabled derelict Mary Celeste (found outside the Triangle anyway) to the Ellen Austin from which even the salvage crew disappeared (the writer of the 1944 story never revealed his source) to the famous matter of the five Avenger bombers and their rescue plane which never returned, the Star Ariel, that DC-10, Marine Sulphur Queen, Sno' Boy, etc. -- they're all there. The author finds plausible explanations for most of the tragedies -- bad weather (conveniently not reported by the cult), communication gaps, fires, failed instruments, darkness inhibiting searches, etc. The real mysteries exist because of lack of firm evidence, and the legend, Kusche states, is a ""manufactured"" one. In all, a superior weapon for all sensible squares to use for the bedevilment of Triangle believers.
