The mystery of Bermuda Triangle

The Bermuda Triangle is a mythical section of the Atlantic Ocean roughly bounded by Miami, Bermuda and Puerto Rico where dozens of ships and airplanes have disappeared. Unexplained circumstances surround some of these accidents, including one in which the pilots of a squadron of U.S. Navy bombers became disoriented while flying over the area; the planes were never found. Other boats

and planes have seemingly vanished from the area in good weather without even radioing distress messages. But although myriad fanciful theories have been proposed regarding the Bermuda Triangle, none of them prove that mysterious disappearances occur more frequently there than in other well-travelled sections of the ocean. In fact, people navigate the area every day without incident.

The area referred to as the Bermuda Triangle, or Devil’s Triangle, covers about 500,000 square miles of ocean off the south-eastern tip of Florida. When Christopher Columbus sailed through the area on his first voyage to the New World, he reported that a great flame of fire (probably a meteor) crashed into the sea one night and that a strange light appeared in the distance a few weeks later. He also wrote about erratic compass readings, perhaps because at that time a sliver of the Bermuda Triangle was one of the few places on Earth where true north and magnetic north lined up.

On a sunny day 58 years ago, five Navy planes took off from their base in Florida on a routine training mission, known as Flight 19. Neither the planes nor the crew were ever seen again. Thus was a legend born. The Bermuda Triangle is an area roughly bounded by Miami, Bermuda, and Puerto Rico. No one keeps statistics, but in the last century, numerous ships and planes have simply vanished without a trace within the imaginary triangle. Unusual features of the area had been noted in the past. Christopher Columbus wrote in his log about bizarre compass bearings in the area. But the region didn't get its name until August 1964, when Vincent Gaddis coined the term Bermuda Triangle in a cover story for Argosy magazine about the disappearance of Flight 19. The article stimulated a virtual cottage industry in myth-making.

Many exotic theories have been propounded to explain what happened to the missing travellers. The disappearances have been attributed to the machinations of enormous sea monsters, giant squid, or extra-terrestrials. Alien abductions, the existence of a mysterious third dimension created by unknown beings, and ocean flatulence—the ocean suddenly spewing great quantities of trapped methane—have all been suggested as culprits.

The reality, say many, is far more prosaic. They argue that a sometimes treacherous Mother Nature, human error, shoddy craftsmanship or design, and just plain bad luck can explain the many disappearances. "The region is highly traveled and has been a busy crossroads since the early days of European exploration," said John Reilly, a historian with the U.S. Naval Historical Foundation. Lieutenant A. L. Russell, in the U.S. Coast Guard's official response to Bermuda Triangle inquiries, writes: "It has been our experience that the combined forces of nature and the unpredictability of mankind outdo science-fiction stories many times each year."

The legend of the Bermuda Triangle will be forever tied to the fateful flight that took place on December 5, 1945. Flight 19 originated at the U. S. Naval Air Station in Fort Lauderdale, Florida. Five TBM Avenger Torpedo Bombers carrying 14 men took off at roughly 2:10 in the afternoon that day on a routine navigational training mission. Led by instructor Lieutenant Charles Taylor, the assignment was to fly a three-legged triangular route with a few bombings practice runs over Hen and Chickens Shoals.

Taylor, in an age before the Global Positioning System (GPS) became commonplace for navigation, got hopelessly lost shortly after the bombing run. Pilots flying over water in 1945 had to rely on compasses and knowing how long they'd been flying in a particular direction, and at what speed. Both of the compasses on Taylor's plane were apparently malfunctioning. Transcripts of in-flight communications suggest he wasn't wearing a watch. There are no landmarks in the middle of the ocean. The planes flew in one direction then another as balmy daylight turned to stormy seas in the darkness. Taylor is heard formulating a plan; as soon as the first plane's fuel level dipped below 10 gallons, all five planes were to ditch at sea. The Avenger was known as an extremely rugged plane. Pilots sometimes called them "Iron Birds" or Grumman ironworks, said Mark Evans, a historian at the Naval Aviation History branch of the Naval Historical Center. "They were built like tanks," he said. "Time and again they'd come back from battle all shot up and still functioning. Pilots loved them."

They were also very heavy, weighing more than 10,000 pounds (4,535 kilograms) empty. When ditched, the Avenger would go down hard and fast. The possibility of anyone surviving a landing in high seas was slim, the chance of surviving the night in the cold waters was nil, the likelihood of the wreckage making a quick descent to the bottom was high.

A massive land and sea search was mounted, but neither bodies nor wreckage were ever found. Adding to the tragedy, one of the rescue planes also disappeared along with its 13-man crew. Their plane, a PBM Mariner, was nicknamed the "flying gas tank"; the slightest spark or a lit match could cause an explosion. A ship in the area reported seeing a huge fireball and crossing through an oil slick at the exact time and place where the plane would have been. The Navy halted production of that plane in 1949. In the Navy's final report, the disappearance of Flight 19 was blamed on pilot error. Taylor's family protested and, after several reviews, the verdict was changed to "causes or reasons unknown."

"The biggest issues in that area normally are hurricanes, but it's not particularly a spawning area for storms," said Dave Feit, chief of the marine forecast branch of the National Oceanic and Atmospheric Administration's Marine Prediction Center.

However, Feit pointed out, the Gulf Stream travels along the western edge of the triangle and could be a factor. The Gulf Stream is like a 40- to 50-mile-wide (64- to 80-kilometer-wide) river within the ocean that circulates in the North Atlantic Ocean. The warm water and two- to four-knot currents can create weather patterns that remain channelled within it.

"If you have the right atmospheric conditions, you could get quite unexpectedly high waves," said Feit. "If wave heights are eight feet outside of the Gulf Stream, they could be two or even three times higher within it. Sailors can sometimes identify the Gulf Stream by the clouds and thunderstorms over it." The Coast Guard also notes that unpredictable Caribbean-Atlantic storms can yield waterspouts that often spell disaster for pilots and mariners.

In all probability, however, there is no single theory that solves the mystery. As one skeptic put it, trying to find a common cause for every Bermuda Triangle disappearance is no more logical than trying to find a common cause for every automobile accident in Arizona. Moreover, although storms, reefs and the Gulf Stream can cause navigational challenges there, maritime insurance leader Lloyd’s of London does not recognize the Bermuda Triangle as an especially hazardous place.
