Hanoi (VNA) – Malaysian authorities released a report on July 30 on the disappearance of the Malaysia Airlines Flight 370, which includes the possibility of "intervention by a third party."

In a press conference providing the information of the flight’s pilots, Chief Investigator Kok Soo Chon said that there was no evidence of abnormal behaviour or stress in the two pilots that could have led them to hijack the plane.

"We are not of the opinion that it could be an event committed by the pilots," Kok said.

He added that the captain of the flight, Zaharie Ahmad Shah, married with three children, is an experienced pilot with 18,000 hours of flying.

"We cannot rule out unlawful interference by a third party," such as someone holding the pilots hostage, he said. However he added that no group has claimed to have hijacked the plane and no ransom demands have been made, compounding the mystery.

The plane carrying 239 people from Kuala Lumpur to Beijing vanished on March 8, 2014, and is presumed to have crashed in the southern Indian Ocean.

A 440-page report released by the Australian Transport Safety Bureau (ATSB) last year revealed that six hours prior to the disappearance of the MH370, Zaharie operated an emulated flight with a similar route from Malaysia to the Indian Ocean, yet Malaysian police confirmed that he did not perform any abnormal actions. –VNA
