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 disappearance 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 p lanes have reported that their magnetic compasses 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.
