Underwater drone to probe sonar contacts in missing plane hunt
A ship involved with the deep-sea sonar search for missing Malaysia Airlines Flight 370 is being fitted with equipment to examine several sonar contacts on the remote sea bed west of Australia.
The Australian Transport Safety Bureau said none of the sonar contacts had the characteristics of a typical aircraft debris field, but some exhibited man-made properties and must be investigated before they could be eliminated as having come from the Boeing 777.
Officials have previously said that more than 20 sonar contacts required closer examination by an underwater drone.
The transport bureau is heading up the search for the plane in a desolate stretch of the Indian Ocean off Australia's west coast.
The aircraft vanished with 239 people on board during a flight from Kuala Lumpur, Malaysia, to Beijing, on March 8 2014.
