Missing Malaysian jet: Most difficult search in history continues

On his part, Malaysian Prime Minister Razak thanked the efforts by Australia and other countries involved in the search operation, saying "their commitment will not be forgotten".

"In a time of great tragedy... differences have been set aside, as 26 nations have united behind a common cause. The disappearance of MH370 is without precedent, so too is the search," said the Malaysian prime minister.

"The disappearance of MH370 has tested our collective resolve. Faced with so little evidence, and such a difficult task, investigators from Australia, China, France, Malaysia, the UK and the US have worked without pause to reveal the aircraft's movements. Their collective efforts have led us here," he added.

Razak also asserted that his country would not give up, because he knew "many families cannot start to grieve until the plane is found".

According to the JAAC update, the two prime ministers also spoke to personnel at the Royal Australian Air Force (RAAF) Base Pearce near Perth, the hub of the aerial search, where they honoured the efforts of the eight nations involved.

“It was a very heart-warming experience to be introduced to the leaders of the various countries -- from China, from the United States, from New Zealand, from Japan, from South Korea, from New Zealand and, of course, from both Australia and Malaysia,” Prime Minister Razak said.

“I know it is a daunting task to go out there in very inclement weather, in very challenging circumstances. Malaysia is indeed grateful for your courage and for your commitment.”

Razak also announced that Australia had accepted Malaysia's invitation to participate as an accredited representative in the investigation and would continue to work closely together to draw up a comprehensive agreement on the search.
