Far belw the surface f the Nrth Atlantic Ocean, in a rughly triangular area knwn as the the Bermuda Triangle, lie mre than 50 shipwrecks and 20 plane wrecks. What makes these wrecks s mysterius is that the cause f their fate remains largely unknwn--ships were abandned withut apparent reasn, distress singles were never sent and aircraft were lst withut trace.
Sme believe that supernatural frces are respnsible, while thers put the accidents and disappearances dwn t cincidence. Scientific theries, meanwhile, include pilt errr when trying t navigate the area, and huge “rgue waves” caused by terrible strms. Althugh many ships and planes crss the the Bermuda Triangle withut incident, the stries behind thse dmed vessels’ fates cntinue t capture peple’s imaginatins.
