A 1,500 page report from the Malaysian government on missing Malaysia flight MH370 has answered few questions, but it has responded to numerous conspiracy theories surrounding the plane's disappearance. He said there was no evidence of abnormal behaviour or stress in the two pilots that could lead them to hijack the plane but all passengers were also cleared by police and had no pilot training.
Malaysian air traffic control authorities should have issued a distress phase earlier when they failed to make contact with Malaysia Airlines flight 370 (MH370) on March 8, 2014.
Head investigator Kok Soo Chon said, while its unlikely a deliberate diversion by the pilot or first officer, they can not exclude the possibility of a third party interference.
"If the wreckage has not been found, if no victims have been found, how can we call our report the final report?" he said.
The recorded changes in the aircraft flight path following waypoint IGARI, heading back across Peninsular Malaysia, turning south of Penang to the north-west and a subsequent turn towards the Southern Indian Ocean were hard to attribute to any specific aircraft system failures.
"It is too presumptuous of us to say this is the final report", Kok said.
Other theories disproved by the report included speculation that the plane's cargo, which included 4,566kg of mangosteens and 221kg of lithium-ion batteries, had sparked to cause a fire.
Malaysia's government has said it is open to resuming searching if credible evidence of the plane's location emerges.
In a separate statement, the Minister of Transport Anthony Loke Siew Fook said that the Ministry will review the safety recommendations proposed in the report and will take appropriate improvement measures to prevent similar future air accidents.

Video surveillance indicates that Cowell allegedly entered the parking structure at the station and discarded his clothes. BART Police says it has ramped up patrols and working video cameras have been placed throughout stations and on the cars.
Chief investigator Kok Soo Chon told reporters in Kuala Lumpur that given the plane had been manually diverted and the communications systems turned off by hand, process of elimination meant someone else might have been responsible.
Grieving families who had advanced sight of the report before its official release this morning said it provided no new answers, according to Reuters news agency.
Investigators also noted both Kuala Lumpur Air Traffic Service Centre (KL ATSC) and Ho Chin Minh Area Control Centre (HCM ACC) lost valuable time when events started unfolding.
The report called for modern passenger jets to be globally trackable.
Officials said this is still not a final accounting because the plane has not been found.
"The disappearance of MH370 and the search effort are unprecedented in commercial aviation history", the Malaysian report said Monday.
It was the second major search after Australia, China and Malaysia ended a $200million hunt across an area of 120,000 square kilometres previous year. It says all the evidence points to a an incontrovertible conclusion - that it was under manual control, and that it was deliberately flown out into the Indian Ocean.
The report concluded that several turns that took the plane off its path from Kuala Lumpur to Beijing and southwards on its long journey to the southern Indian Ocean were likely made manually, not by the autopilot.
Theories range from mechanical error or a remote-controlled crash, to more weird explanations like alien abduction and a Russian plot. The only confirmed traces of the aircraft have been three wing fragments washed up along Indian Ocean coasts.
