The bermuda triangle is certainly not fixed and its effect can be experienced outside of the triangle too.
The disappearances are ascribed to UFO's and alien activity, city of Atlantis lost under the triangle, and ious other technical, natural and geographical reasons.
Whenever any plane or ship disappears in the Triangle, its debris cannot be found. The reason behind this is that Gulf Stream runs near the triangle, which quickly gets rid of the debris.
At least 1000 lives are lost within the last 100 years. On average, 4 aircraft and 20 yachts go missing every year.
The first person to report about Bermuda Triangle was Christopher Columbus. He wrote in his journals that inside the triangle, the ship's compass stopped working and he also saw a fireball in the sky.
Bermuda Triangle is one of the rare places on earth where the compass does not point towards Magnetic North. Instead of that, it point towards true north, which creates confusion and that's why so many ships and planes lost its course in the triangle
