Then radio contact was broken The flight did not return, and the planes that were sent to look for the bombers also failed to return. A massive search operation was mounted, but no trace of the missing planes or their pilots was founD.They had simply and inexplicably disappeareD.This event was sufficient to confirm in many people's minds that the so-called 'Devil's Triangle'. or 'Bermuda Triangle' —a section of the North Atlantic bounded roughly by Bermuda, Florida and Puerto Rico— really was haunteD.and in some mysterious way was responsible for the loss of ships and planes. In all, in this area (3 900 000 square kilometres) of open sea, more than 50 ships and 90 planes have mysteriously disappeareD.These include the US Navy ship Cyclops in 1918 and the merchant vessel Marine Sulphur Queen in 1963.

After all, ships, boats and planes are lost at sea in all parts of the world due to weather, mechanical failure or human error, and several of the losses are mysterious. The Marie Celeste, an American cargo boat, for example, was found in 1872 off the coast of Portugal in perfect order but with no crew on boarD.Their disappearance has never been explaineD.Did some of them mutiny and then escape? Were all the crew killed by some unknown agent? Did they try to escape from some danger or other? We shall probably never know.However, regardless of the theories which exist about the 'Bermuda Triangle', ships, boats and planes continue to travel daily trough the area with great frequency and it has not been proven that a higher percentage of accidents and losses occur in this section of the North Atlantic than in other areas of the world's oceans.To many people the Bermuda Triangle is really a mystery because ______.A.it is called 'Devil's Triangle'B.a lot of books have been written about the areaC.the lost continent of Atlantis lies somewhere in that areaD.there have been may unexplainable disappearances of ships and aircrafts in that area
