PASSAGE – III

The Bermuda Triangle has always been shrouded in mystery. The missing ships and planes have roused irrevocable inquisitiveness among people. Many theories pertaining to extraterrestrials, evil humans, anti gravity, magnetic field, oceanic flatulence and other technical sounding and weird hypothesis have been put forth. But a few investigators contrive ill luck, pirates, incompetence of navigators to be the cause of these missing  ships  and  planes.  A  few  diehard  rationalists  believe there is no mystery element that needs to be explained as the figures pertaining to wrecks is common when there is such exceeding traffic on sea. The missing ships perhaps had never touched Bermuda Triangle’s domain. No scientific derivations prove any aura of mystery enveloping Bermuda Triangle. The surprising subject rather is how Bermuda Triangle became so centralized a topic of mystery.

Probably it began with the disappearance of five Navy planes in 1945. Logic states they vanished due to bad weather and failure of compass field. The trainee pilots lacked the expertise to face the sudden ordeal. The other declaration was that the planes collapsed due to fuel shortage. But in no way any mystery element coincides. This has been a revered subject for writers as a lot of written material can be found about it. It’s perhaps surprising that no one took the investigation on the mystery. Rather they all cashed this mystery to write their best sellers. They passed these derivations of the past without pondering on them. Slowly Bermuda Triangle mystery evolved as a farce as these irresponsible authors did not foresee how their accounts would change a myth into a truth in public eye. The mass media too played in phlegmatic attitude in solving this. They plundered the mystery element to spice up their news items. Soon the superstitious called it the ‘Devil’s Triangle’. Some considered it to be the alien’s domain and some called the Atlantis the cursed water which gobbled whoever came across. But it’s a fact that all these exaggerations have helped to lend fear and fascination to the world’s greatest mystery the Bermuda Triangle.
