Australia says four planes are now searching in a new area in the Indian Ocean for possible signs of the Malaysian airliner that went missing three weeks ago.
John Young, manager of the Australian Maritime Safety Authority's emergency response division, said Friday that four planes were in the area, and that six ships were headed there.
Officials said earlier that the search zone had been shifted 680 miles to the northeast after new analysis of radar data suggested the plane flew faster than thought and used more fuel, which may have reduced the distance it traveled.
The search comes as the weather cleared enough Friday to allow planes to hunt for fresh clues to the fate of the plane carrying 239 people that went missing March 8.
