Basically, there are these "bubble pockets". They are underwater in the triangles. When they pop they release huge bubble into the ocean and they move upward very fact. If a boat happens to be underneath them (they can cover and area of up to 1 square mile) it has the power the split the boat in half, or deform it, or just flat out flip it and sink it. There is a certain type of chemical (can't remember the name) that is released into the air, it shuts down navigation systems, can even thicken the air, and makes you lose your sense of direction. That explains the crashes planes.
That was on discovery channel and has been scientifically proven.
