Relatives of people aboard Flight MH370 said they hoped a long-awaited report into the plane's disappearance might give them answers about one of the world's most enduring aviation mysteries.
KUALA LUMPUR - Investigators released a report on missing Malaysia Airlines flight MH370 on Monday, saying the Boeing 777&39;s controls were likely deliberately manipulated to take it off course but they were not able to determine who was responsible.
They had no conclusion about what happened aboard the plane that vanished with 239 people on board en route to Beijing from Kuala Lumpur on 8 March 2014, leaving one of the world&39;s greatest aviation mysteries unsolved.
"The answer can only be conclusive if the wreckage is found," Kok Soo Chon, head of the MH370 safety investigation team, told reporters.
Malaysian and international investigators have been looking into why the Boeing 777 jet veered thousands of miles off course from its scheduled route before eventually plunging into the Indian Ocean.
Experts believe someone may have deliberately switched off MH370’s transponder before diverting it over the Indian Ocean.
The last communication from the plane was from the Captain Zaharie Ahmad Shah who signed off with “Good night, Malaysian three seven zero”, as the plane left the Malaysian airspace.
A 440-page final report by the Australian Transport Safety Bureau (ATSB) last year showed that Zaharie had flown a route on his home flight simulator six weeks earlier that was "initially similar" to the one actually taken by MH370.
A forensic report by the Malaysian police previously concluded that there were no unusual activities other than game-related flight simulations.
Kok said the investigators examined the history of the pilot and the first officer, and they were satisfied with their background and training and mental health.
"We are not of the opinion it could have been an event committed by the pilots," he said, but added they were not ruling out any possibility since the in-air turn back was done manually and the systems in the plane were also manually turned off.
"We cannot exclude that there was an unlawful interference by a third party," Kok said.
He added all the passengers of the 15 countries had their backgrounds checked by their respective countries and all came back with a clean bill of health.
