Investigators later determined, through an analysis of "handshakes" between the plane and an Inmarsat telecommunications satellite, that MH370 had eventually turned and flew south for hours.
Analysis of a flight recorder from that plane showed that a lithium-ion battery experienced a sudden drop in voltage and was not overcharged, the Japan Transport Safety Board said Wednesday.
No-one will ever know how the plan to attack the terrorists was hatched, but early indications from analysis of the recordings suggest it began in the front of the plane in first class.
