Underwater drone to investigate sonar contacts in MH370 hunt

SYDNEY (AP) — A ship involved with the deep-sea sonar search for missing Malaysia Airlines Flight 370 is being fitted with a drone that will examine several sonar contacts of interest on the remote seabed west of Australia, officials said Wednesday.

None of the sonar contacts exhibit the characteristics of a typical aircraft debris field, said the Australian Transport Safety Bureau, which is heading up the hunt for the Boeing 777 in a desolate stretch of the Indian Ocean.

With the weather improving, the Chinese vessel Dong Hai Jiu 101 is being fitted with a video camera-equipped remotely operated vehicle that will scrutinize the sonar contacts.
