PERTH: Australian navy vessel Ocean Shield, which is fitted with a US-supplied "black box" detector, was Friday expected in the area being scoured for wreckage of Flight MH370 as 14 planes continued the arduous search.

Nearly a month after the Malaysia Airlines jet carrying 239 people vanished, authorities still have no idea how or why it crashed and warn that unless the black box is found, the mystery may never be solved.
