The co-pilot of a missing Malaysian jetliner spoke the last words heard from the cockpit, the airline’s chief executive said on Monday, as investigators consider suicide by the captain or first officer as one possible explanation for the disappearance.
No trace of Malaysia Airlines Flight MH370 has been found since it vanished on March 8 with 239 people aboard. Investigators are increasingly convinced it was diverted perhaps thousands of miles off course by someone with deep knowledge of the Boeing 777-200ER and commercial navigation.
A search unprecedented in its scale is now under way for the plane, covering an area stretching from the shores of the Caspian Sea in the north to deep in the southern Indian Ocean.
Airline chief executive Ahmad Jauhari Yahya also told a news conference that it was unclear exactly when one of the plane’s automatic tracking systems had been disabled, appearing to contradict the weekend comments of government ministers.
