Some conclusions based on research from teh Univ. of Arizona research librarian...
Kusche came to several conclusions: With this area being one of the busiest shipping areas in the world, the proportion of losses was no greater than anywhere else.
In an area with frequent tropical storms, the total disappearance of some ships was not unlikely or mysterious, and the number of such disappearances was exaggerated by sloppy research, when a missing boat would be reported in the press, but not its eventual return to port.
In actual disappearances, the circumstances were frequently misreported in the Bermuda Triangle books: the number of ships disappearing in supposedly still, calm weather did not jibe with press weather reports published at the time.
