Search for Malaysia Airlines Flight 370

The search zone for missing Malaysia Airlines flight MH370 will be doubled if nothing is found in the huge undersea area now being scanned for wreckage, Malaysia, Australia and China announced Thursday.
      

A fourth ship with enhanced search capabilities has been commissioned to join the underwater hunt for missing flight MH370, Australian authorities said Jan. 14, with 14,000 square kilometres (5,405 square miles) of the sea floor scoured so far.
      

Relatives of MH370 passengers have criticised beleaguered Malaysia Airlines after an official reportedly said authorities would set a date to announce the plane "lost", with an industry source saying such a declaration would see the search called off.
