skepticism-of-ufo-theories

This chapter analyzes the geographic distribution and characteristics of mysterious disappearance zones, termed 'vile vortices,' where ships, planes, and submarines vanish without trace. The author identifies six major lozenge-shaped areas between 30° and 40° latitude in both hemispheres, correlating their locations with oceanic surface currents and noting their unusual frequency of disappearances compared to other regions. The chapter also critiques popular UFO-related explanations and highlights ongoing uncertainty and speculation about the phenomena.
