Good subject to bring up, I've come across this info as well. This island might have been used for cabal purposes, but how and why to make it disappear is a great to speculate on. Parallel universes could be who knows.

I know government insider Robert Dean and others have talked about technology existing to cloak huge land masses to make them look invisible and literally u would have to get so close that u enter this cloaking system and than would see it.

But if researchers have been there and still not seen anything than who knows....Truth is stranger than fiction!
