14 planes, 13 ships continue MH370 search

The search for missing Malaysia Airlines Flight MH370 in the Indian Ocean will resume with up to 14 planes and 13 ships, the federal government's Joint Agency Co-ordination Centre (JACC) says.

JACC said the search for the downed jet would on Thursday focus on an area of about 57,923 square kilometres, about 2280 kilometres northwest of Perth.

Up to 10 military aircraft and four civil planes would take part, JACC said.

It forecast scattered moderate southeasterly winds with isolated showers in the search area.

The agency said the underwater search would also continue, involving the Australian ship ADV Ocean Shield, Chinese ship Haixun 01 and HMS Echo.

"Aircraft and ships reported spotting a large number of objects during yesterday's search, but only a small number were able to be recovered," JACC said.

"None of the recovered items were believed to be associated with MH370."

There is still no proof of what happened to the plane, but possible ping signals have been detected in the southern Indian Ocean, potentially emanating from the plane's black box flight data and cockpit voice recorders.

The search zone was on Wednesday narrowed down to 1300 square kilometres after more audio signals consistent with the black box were detected.

The flight disappeared on March 8 while flying from Kuala Lumpur to Beijing with 239 people on board.
