In 2014 , Malaysia Airlines ’ flight of stairs MH370 from Kuala Lumpur to Beijing veered off the usual flight route before disappearing into the Indian Ocean . Four years later and we still do n’t bang where it put down , what happened to its remains and the 239 rider on board ,   or until now , what caused it to make the roundabout way in the first place .

On Monday , Malaysian investigators released a 495 - page report into the tragedy , initially knight the “ last story ” , expose it was extremely likely the planing machine ( a Boeing 777 ) had been manually manipulate to deviate from the pre - plotted road on March 8 , 2014 . They still do not recognize who was responsible .

“ The turning back could not be ascribe to an anomalous system , ”   Dr Kok Soo Chon , the detective in charge of the   investigating , told an audience at   a printing press conference in Putrajaya .

" It has been established that the air twist back was done under manual ascendence , not robot pilot . "

Up until this point , the official theory give was that the carpenter’s plane had ram in an " unresponsive crew / hypoxia event " . Experts believe Zaharie Ahmad Shah , the pilot , had been unconscious   in the hours   leading up to the incident , the Guardianreported in March . The aeroplane   continue to serve on automatic pilot before it ran out of fuel and plunged into the sea .

The Modern report complicate the theory that the aeroplane was on automatic pilot . It also course in contrast to other theories that advise a mechanical or computer malfunction is to fault . And while the detective say they can not dismiss " unlawful interference by a third party " , they have also said they do not surmise the   fender or first officer of concoct a suicide mission in a similar vena to theGermanwings incidentin 2015 .

“ We have analyze the pilot and the first officer and we are quite satisfied with their background signal , with their grooming , with their genial wellness , ” Kok added .

“ We are not of the opinion that it could have been an case committed by the pilot . ”

While he was quick to say he was not ruling it out , Kok did say two psychiatrists had examine the audio transcription and CCTV footage of the pilot program before the crash and found no grounds of anxiety or focus . scope check on all the passengers also come back show a uncontaminating bill of wellness .

Which all seems to intimate the write up does more to dismiss certain theory than it does to provide some sort of conclusion to the mystery . Kok tell reporters , the only mode it can be solve is if the wreckage is found and that seems unlikely   – so far , only three wing fragments base on the Indian Ocean coast are definitely from the aircraft , Reutersreports .

What we do sleep with is that flight   MH370 made orbiter tangency seven times in the six hour after the plane left radio detection and ranging screen , the last time suggests the plane ’s location was near the Australian coast in the South Indian Ocean . The very last affair hear from the trajectory is a goodnight message from the fender . ( " right nighttime ,   Malaysian three seven zero . ” ) We now also be intimate that the flight ’s four emergency locator transmitter malfunctioned so that they did not trigger signals that may have help oneself site the Boeing 777 .

According to Malaysia ’s Prime Minister , Mahathir Mohamad , the search will not be go forward unless new evidence is found .
