The search for flight MH370, which vanished on March 8 with 239 people on board, has narrowed to a 10 sq km patch of sea floor about 2,000 km west of the Australian city of Perth.
Search authorities and the Australian and Malaysian governments have said a series of sonar signals, or "pings", traced to the area may have emanated from the plane's "black box" and present the most credible lead as to its whereabouts.

However no pings have been detected in almost two weeks and authorities now fear that, with the flight data recorder's battery several weeks past its expected expiry date, the black box may not emit further signals.
A US Navy remote controlled submarine, the Bluefin-21, was on its ninth mission scanning the largely unmapped stretch of sea bed where the pings are believed to have come from, with still no trace found, Australian search officials said today.
"Bluefin-21 has searched approximately two-thirds of the focused underwater search area to date. No contacts of interest have been found to date," the Joint Agency Coordination Centre said in a statement.
