The new conventional wisdom is that Malaysian Airlines MH370 cruised south-southwest until it ran out of fuel hundreds of miles southwest of Perth, Australia. Whereupon it ditched in the lonely south Indian Ocean, broke up, and much of it sank.
What is unclear now, and may never be known, is why. This seems an unlikely way to commit suicide. I'd suppose a suicide would want to get it finished, not fly on for hours beyond the point of no return.
Perhaps everybody aboard was already unconscious or dead and the plane simply continued on autopilot until out of fuel. If so, by whom did the transponder get turned off?
You have to wonder will we ever know what happened? Much depends on whether the cockpit recorders, aka the black boxes, are ever recovered.
