PART II

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.
