The disappearance of the doomed passenger jet MH370 has been described as "calculated" and "deliberate", in the latest in a long line of conspiracy theories.
Veteran commercial pilot Ewan Wilson and investigative journalist Geoff Taylor have spent months analysing the aircraft's final hours, before all 239 passengers and crew on board vanished without a trace.
The pair have concluded that the flight's mysterious disappearance and apparent failure of its tracking systems could only be the result of deliberate tampering.
Wilson, who previously ran two airlines, also jetted to Malaysia to interview investigators and relatives of MH370's pilot Zaharie Ahmad Shah.
He and journalist Taylor, both from New Zealand, have reviewed all published data undertaken by Malaysia and other nations involved in the search for the tragic craft.
Air traffic controllers lost contact with the Boeing 777 soon after it took off from Kuala Lumpur on March 8 on a night flight to Beijing over waters between Malaysia and Vietnam.
Wilson told stuff.co.nz that the conclusion of his book, Good Night Malaysian 370: The truth behind the loss of Flight 370, will shock the public.

Malaysian Airlines Conspiracy Theories
The authors say they have systematically ruled out malfunctions or freak accidents, saying there was no other reason for the flight's change of route.
Describing their findings, pilot Wilson, who has training in investigating air crashes, said: "For the first time we present a detailed analysis of the flight, the incredible route it took, and who we believe was in charge of the aircraft as it plunged into the Indian Ocean."
The authors said that relatives of those on board were not being told the truth about the diversion.
Journalist Taylor added: "For the sake of the relatives of those on the flight the truth needs to be out there.
"We visited the departure lounge where families sat full of excitement and anticipation waiting for their boarding call. Surely they deserve better than a cover up?"
He added: ‘What happened to MH370 was no accident
"It was deliberate and it was calculated and it should never have been allowed to happen."
