Aim: The aim of this article is to discuss un biasedly and objectively why the disappearance/crash is not due to pilot-suicide. Method: The authors present their own postulates as to why the disappearance/crash is not a pilot murder-suicide, besides briefly discussing relevant aspects of the safety investigation report. The authors also make reference to other related articles and news reports. Results: The evidence contradicts claims that it was a pilot murder-suicide “meticulously planned” by either of the pilots – the route could not have been planned by the captain and the ‘hijacking-pilot’ could not have killed everybody else by causing cabin-depressurization, and consequent hypoxia, before deliberately crashing. The flight-path of the MH370 do not resemble the path of eight previously ascertained commercial-airliner pilot-suicides, while it resembles the path of nine previous suicides in which it was hijackers who were flying the plane. Usual psychiatric suicide-risk assessment of both the pilots prior to the flight did not reveal any suicide-risk, and revealed that they were stable socio-economically, physically and mentally. Conclusion: The disappearance/crash of the MH370 is not due to pilot (mass) murder-suicide.
