On the 5th December 1945, Flight 19, which consisted of five US Navy planes, took off from Fort Lauderdale, Florida in fine weather. There was a total of fourteen men on board the planes. The planes were in good condition; they had the best equipment on board including compasses and radios, and they also carried life rafts. The planes could float on water for ninety seconds. One and a half hours after the take-off, a radio message from one of the planes was heard at the control tower at Fort Lauderdale. “I don’t know where we are.” After that the planes could no longer speak to the control tower, but they could speak to and hear each other, and the control tower could hear them. “The magnetic compass is going crazy.” “We’re completely lost.” No other messages were heard after that. Nobody else heard from the planes or saw them again. Three hundred planes and many boats searched the area, but not one trace of Flight 19 was found. Then one of the planes that was sent to look for them also disappeared completely. These planes had disappeared in a very mysterious part of the world in the western Atlantic Ocean where lots of strange events have taken place. The mystery started long before 1945, and since that year many other ships and planes have also disappeared in this area. It is called the Bermuda Triangle. It is a large triangular area of the ocean with the island of Bermuda at its northern tip. Planes and ships disappear in other parts of the world, but there are more disappearances in the Triangle than in other areas. For years now scientists and others have been puzzled by this mystery. There have been many attempts to explain why people, planes and ships disappear in such high numbers here. One writer, John Spencer, believes that the ships and planes have been carried off from the sea and sky by flying saucers or UFOs from another planet. Since there are millions of other planets in the universe, Spencer believes there must be other intelligent creatures somewhere in the universe. These creatures are interested in collecting humans and their equipment so that they can examine them carefully. Another theory is that the geography of the area is responsible for the disappearances of the ships and planes. Bermuda lies on an earthquake belt. Underwater earthquakes result in large waves appearing suddenly. These waves are so big that they can break a ship into pieces. In the air, a similar thing can happen to airplanes because of sudden strong winds. As with Flight 19, many boats and planes have reported that their magnetic compassed stop working properly in the Bermuda Triangle. Normally a magnetic compass points towards magnetic north. However, the Bermuda Triangle is one of the two places on Earth in which a compass points towards true north. Therefore, there is something strange about the magnetic properties of the area. Many people have found these explanations difficult to believe. However, the most recent theory has a scientific basis and is more believable. The discovery of methane gas on the seafloor of the Bermuda Triangle started a scientist, Dr. Mclver, thinking about an explanation for the mysteries. Sometimes large amounts of the gas escape from the seafloor and rise into the air. This could produce large waves on the surface which would make a ship sink. When the gas mixes with air, it could also cause a ship’s engine to stop or it could start a fire. Similarly, as the mixture rises into the air, it could cause an airplane’s engine to stop or explode. The explosions would break a ship or a plane into tiny pieces. This latest theory has yet to be proved but seems to offer a better explanation as to why Flight 19 and all the other planes, ships and people have disappeared in the Bermuda Triangle.
