PUTRAJAYA, Malaysia, July 30 (Xinhua) -- A detailed report on the disappearance of Malaysia Airlines flight MH370 in 2014 released by a safety investigation team Monday failed to determine the cause behind the mishap and left many questions unanswered due to lack of evidence.
The 800-plus-page report, while reviewing several aspects ranging from airworthiness and maintenance to cargo assignment and wreckage information, said the probe team could not determine why the plane went off its filed flight route.
"The change in flight path likely resulted from manual inputs," it added.
Calling the disappearance of MH370 and the searches for it "unprecedented in commercial aviation history," the report said improvements must be undertaken to ensure that this type of event is identified as soon as possible.
Also, the international aviation community needs to provide assurance to the traveling public that the location of current-generation commercial aircraft is always known, it recommended.
Though Malaysia's Transport Minister Anthony Loke previously described it as the final and full report, Kok Soo Chon, head of the Malaysian International Civil Aviation Organization Annex 13 Safety Investigation Team for MH370, said the report is not final and is only about safety investigation to provide safety recommendations.
