A detailed oceanographic map has surfaced which predicted 12 months ago that any debris from the missing Malaysian Airlines flight MH370 could wash up exactly where a large piece of aircraft wing has been discovered on Reunion island near Madagascar in the Indian Ocean. The map was prepared a year ago and predicted the various possible paths of debris if MH370 did indeed crash into the water in the so-called "Southern Corridor," the vast area of the Indian Ocean that became the focus of international search efforts in the months after the plane disappeared.
