The passengers and crew of the missing Malaysia Airlines Flight MH370 most likely died from suffocation and coasted lifelessly into the ocean on autopilot, a new report released by Australian officials on Thursday said. In a 55-page report, the Australian Transport Safety Board outlined how investigators had arrived at this conclusion after comparing the conditions on the flight with previous disasters, although it contained no new evidence from within the jetliner. All of that suggested that the plane most likely crashed farther south into the Indian Ocean than previously thought, Australian officials also said, leading them to announce a shift farther south within the prior search area.
