Great, except where are the dead people? And how did the plane keep flying for 7 hours after they were "dead"? Too many unanswered questions, me thinks.
My understanding is that it was the Rolls Royce jet engines that were reporting to satellites for several hours, and that they were reporting some basic maintenance data about themselves (such as whether they were on and functioning). So if the engine had sat in the ocean for five hours and still somehow reported home, it would not have reported that they were still on and functioning.
