(KUALA LUMPUR, Malaysia) — Malaysian authorities believe the last words spoken to air traffic control before Malaysia Airlines Flight MH370 disappeared came from the co-pilot.
“The initial investigation indicates it was the co-pilot who basically spoke the last time it was recorded on tape,” Malaysia’s acting transport minister, Seri Hishammuddin Hussein, told reporters Monday.
The final radio transmission before the Boeing 777 vanished on March 8 was, “All right, good night.” Hussein said the voice is now being analyzed for any signs of stress.
“If he made transmissions before, can you tell any differences in his voice based on frequency, stresses and things like that,” ABC News consultant Tom Haueter, a former National Transportation Safety Board investigator, said, explaining what officials will be looking out for.
Meanwhile, the search for the missing airliner with 239 people on board continues.
“Today I can confirm that search and rescue operations in the northern and southern corridors have already begun. Countries including Malaysia, Australia, China, Indonesia, Kazahkstan have initiated search and rescue operations,” Hussein said.
For its part, Australia is sending two more P-3 Orions and a C-130 Hercules. In all, 56 countries are now involved in the search.
