The problem, a huge problem, in lists of supposed disappearances of airplanes and ocean-going vessels within the Bermuda Triangle (BT), is that most of the listed disappearances did NOT occur within the BT. The BT is an equilateral triangle with its apex at Bermuda and its western side angling to the southern tip of Florida and its eastern side going nearly due south from Bermuda to Puerto Rico. The base of the triangle skirts along the northern edge of the Bahamas from Puerto Rico to southern Florida. This means that all disappearances close to the east coast of the U.S. (except those close to the tip of Florida) were NOT within the BT, unless the delimitation is altered.
Other disappearances are clearly north or south of the BT. Some are listed as located off the coasts of Delaware or New Jersey, etc. These locations are hundreds of miles to the north. Some are even listed in the Gulf of Mexico.
In addition, the sea lanes off North America are some of the world's busiest. It would be a mystery, if there were NOT many disappearances. The huge area which is generally labeled the BT is, after all, an ocean where ships and airplanes can be quickly swallowed, many without trace.
In sum, an extremely busy area, where storms are frequent, covering a huge area, and where accidents are covered over--the supposed mystery is explained.
If there were anything truly mysterious about the area, would captains of naval vessels and pilots of private boats and ships and airplanes of all types fly and sail through the area? I have flown from Miami to London, passing through the BT. I lived to tell the story. Through the decades, so have millions of others.
