Malaysian Prime Minister says officials will 'not give up' on search for missing jet
Thursday, April 3, 2014, 6:34 -
The search goes on, nearly a month after Malaysian airlines flight 370 disappeared.
In a briefing in Perth Thursday, Australian Prime Minister Tony Abbott described the search for the plane as "the most difficult in human history."
He warned there was no guarantee the plane will ever be found.
Abbott also said authorities will spare no effort until they've done everything possible to find it.
Malaysian Prime Minister Najib Razak echoed that sentiment.
"I know that until I find the plane, many families cannot start to grieve. I cannot imagine what they must be going through. But I can promise them, we will not give up," he told reporters.
In the latest search, up to eight aircraft will set out, looking for telltale debris across an 91,500 square-mile zone.
Up to nine ships will search, including one British submarine racing against time to hear the signature pinging from flight 370's flight data recorder.
