The former chief executive of ill-fated Kiwi Airlines says the disappearance of MH370 wasn't an accident.
Commercial pilot and Hamilton City Councillor Ewan Wilson and Fairfax journalist Geoff Taylor have researched the events surrounding the disappearance of Malaysian Airline flight 370 for a book that is due for publication in July.
The authors told Fairfax that Good Night Malaysian 370: The truth behind the loss of Flight 370 leads the readers towards a revelation through the process of elimination.
Mr Wilson, who has qualifications in transport safety investigations, said he and Mr Taylor investigated the evidence for the book and eliminated all the possible scenarios for the disappearance on March 8.
"What happened to MH370 was no accident. It was deliberate and it was calculated and it should never have been allowed to happen," he told Fairfax.
"The disappearance of Malaysia Airlines Flight 370 captured the world's attention and shocked everyone - [the outcome] is gut-wrenching."
The authors travelled to Malaysia to carry out interviews for the book, including with authorities and family members of MH370's pilot, Zaharie Ahmad Shah.
"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?"
It's been more than three months since the Boeing 777 disappeared travelling from Kuala Lumpur to Beijing with 239 people aboard.
There has been no sign of wreckage from where the plane was believed to have crashed in the southern Indian Ocean, but an extensive search has turned up no sign of wreckage.
The Australia Transport Safety Board last week issued a tender to continue the deep-water search for the ill-fated flight.
