The Bermuda Triangle

USS Cyclops

The incident resulting in the single largest loss of life in the history of the US Navy not related to combat occurred when the collier USS Cyclops, carrying a full load of manganese ore and with one engine out of action, went missing without a trace with a crew of 309 sometime after March 4, 1918, after departing the island of Barbados. Although there is no strong evidence for any single theory, many independent theories exist, some blaming storms, some capsizing, and some suggesting that wartime enemy activity was to blame for the loss. In addition, two of Cyclops's sister ships, Proteus and Nereus were subsequently lost in the North Atlantic during World War II. Both ships were transporting heavy loads of metallic ore similar to that which was loaded on Cyclops during her fatal voyage. In all three cases structural failure due to overloading with a much denser cargo than designed is considered the most likely cause of sinking

 Why do ships and planes seem to go missing in the region? Some authors suggested it may be due to a strange magnetic anomaly that affects compass readings (in fact they claim Columbus noted this when he sailed through the area in 1492). Others theorize that methane eruptions from the ocean floor may suddenly be turning the sea into a froth that can't support a ship's weight so it sinks (though there is no evidence of this type of thing happening in the Triangle for the past 15,000 years). Several books have gone as far as conjecturing that the disappearances are due to an intelligent, technologically advanced race living in space or under the sea.
