Malaysia today vowed to hunt Flight MH370 missing for the past 100 days with “renewed vigour”, even as two authors of a yet to be released book on the plane sensationally claimed that its disappearance was “deliberate” and “calculated“.

“It has been 100 days since MH370 went missing. More than 14 weeks have passed since the Malaysian Government first coordinated the search operations for the missing plane. This search effort is unprecedented in sheer scale and complexity involving 26 countries at its peak,” Acting Transport Minister Hishammuddin Hussein said.

“Indeed, as the search transitions to a more challenging phase, we reaffirm our commitment with renewed vigour to locate the missing MH370,” he said in a statement to mark the 100 days of the plane’s disappearance.

Hishamuddin hoped that Malaysia will be credited for doing its best under “near-impossible” circumstances and history will judge it favourably for that.

“100 days after MH370 went missing, its loss remains a painful void in the hearts of all Malaysians and those around the world. We cannot and will not rest until MH370 is found.

We cannot and will not abandon the families of the crew and passengers of MH370. We will, with the grace of God, find this missing plane and so with it begins the process of healing,” he said.

The Beijing-bound Boeing 777-200 — carrying 239 people, including five Indians, an Indo-Canadian and 154 Chinese nationals — mysteriously vanished on March 8 en route to Beijing from Kuala Lumpur.

Meanwhile, two authors from New Zealand who are set to publish a book about the disappearance of the flight MH370, claimed that the tragedy was no accident.

Using a process of elimination, authors Ewan Wilson, a commercial pilot and Hamilton City Councillor, and journalist Geoff Taylor lead readers toward the assertion that the tragedy was not an accident.

They said the conclusion of their book ‘Good Night Malaysian 370: The truth behind the loss of Flight 370’ will shock the travelling public.

“What happened to MH370 was no accident. It was deliberate and it was calculated and it should never have been allowed to happen,” Taylor was quoted as saying by New Zealand—based news website stuff.co.nz.

“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,” Wilson said.

Their book begins at Kuala Lumpur International Airport on March 8 and intertwines the lives of 239 passengers and crew who ultimately met their fate on board what they thought would be a routine flight to Beijing.

The authors travelled to Malaysia to interview authorities and family members of MH370’s pilot Zaharie Ahmad Shah.
