A new book about missing flight MH370 claims its disappearance was a "deliberate" and "calculated" act.

Written by a commercial pilot and a reporter from New Zealand, it claims the Malaysia Airlines plane was ditched in the Indian Ocean.

The writers claim that their conclusion of foul play was reached via process of elimination.

Co-authors Geoff Taylor and Ewan Wilson conducted interviews with relatives of the MH370 pilot, Zaharie Ahmad Shah during their investigations.

The conclusion they reached in Good Night Malaysian 370: The Truth Behind the Loss of Flight 370, is that the incident was no tragic accident.

Taylor said: "What happened to MH370 was no accident. It was deliberate and it was calculated and it should never have been allowed to happen."

Providing some insight on how the pair managed to arrive at their conclusions, while the mystery continues to confound the efforts of governments, Taylor said: "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?

"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 disappearance of Malaysia Airlines Flight 370 captured the world's attention and shocked everyone, it is gut-wrenching."

Australia and Malaysia are co-ordinating efforts to find the missing jumbo jet, which vanished on 8 March. Meanwhile, families of the 239 passengers have started to receive compensation, totalling $50,000 each.
