MH370 was the sixth 'suicide flight'
The pilot of the missing MH370 flight killed himself and his passengers by switching off the oxygen supply in what is the sixth example of such a suicide, according to an aviation expert.
Ewan Wilson, head of Kiwi Airlines, believes Zaharie Ahmad Shah planned mass murder - locking his co-pilot out of the cockpit, depressurising the cabin and shutting down all communication links before turning the plane around.
Having examined all other possibilities, Wilson insists that Shah, 53, is responsible for the deaths of the 227 passengers and 12 crew members on board the doomed Malaysian Airlines flight, which disappeared on March 8.
He said: 'There is a fundamental desire to ignore the mental health issue in the aviation industry.
'Our research indicates there have been five previous incidents of murder/suicide in commercial flights over the last three decades or so, accounting for 422 lives.
'The sad addition of MH370 would bring that number to 661.'
The remarkable claims are made in the book 'Goodnight Malaysian 370', the culmination of a four-month study into the incident, which Wilson co-wrote with the New Zealand broadsheet journalist, Geoff Taylor.
