what is bermuda triangle and where it is?

Answer 1

The Bermuda Triangle, also known as the Devil's Triangle, is a geographical area in the Atlantic Ocean which has been made infamous for the many people, aircraft, and surface vessels said to have disappeared within its bounds. Many of these disappearances involve a level of mystery which are often popularly explained by a variety of theories beyond human error or acts of nature, often involving the paranormal, a suspension of the laws of physics, or activity by extraterrestrial beings. An abundance of documentation for most incidents suggests that the Bermuda Triangle is a mere legend built upon half-truths and tall tales from individuals who sailed the area, then later embellished on by professional writers.

Answer 2

The Bermuda Triangle is the region bordered by the lines extending from the eastern coast of Florida east to the Carribean and north to Bermuda. As far as why planes and ships tend to disappear, it is nothing supernatural. Before radio navigation and communication, vessels would travel straight into storms, while out of communication with the mainland. When they never retuened, they disappeared.
