{{B}}第一篇{{/B}}
One of the greatest mysteries of the world, for 'which scientist have so far been unable to find any satisfactory explanation, is the Bermuda Triangle, sometime called "the Graveyard of the Atlantic." This is an area of the western Atlantic between Bermuda and Florida, roughly triangular in shape where since 1945 at least a hundred ships and planes and over a thousand people have disappeared. No wreckage had been found, no bodies, lifebelts or any other evidence of disater. It is as if these planes, ships and people had never existed. In some cases a routine radio message has been received from aircraft reporting everything in order a few minutes before all contact was lost, in others a weak S. O. S message has been picked up and, in perfect weather, inexplicable references to fog and loss of bearings. In the extraordinary case of five U. $. navy planes disappearing on a routine mission from Florida, the rescue place sent to locate them vanished also. There have been references to the curious white light or haze which is a feature of the sea in part of this area, and it is interesting to note that not only was this light, or streaks of light, observed by the astronauts on their way to space, but was also noted by Columbus, five centuries ago. Whether this light has any connection with the mysterious disappearance is unknown-it is just another curious circumstance as yet unexplained.
Many theories, some bordering on the fantastic, have been advanced to account for the disturbing incidents that occur in the area of the Bermuda Triangle. It has been asked whether these disappearances are caused by extraterrestrial activity, by some undiscovered source of energy, or some dimension of time or space unguessed at by Man. This is no answer and speculation continues as anxiety increases.
