Malaysian Airlines Flight MH370 Search Team Loses Sonar Detector Used To Map Seabed

The team searching for the missing Malaysian Airlines Flight MH370 has lost the sonar detector used in the operation, Australia’s Joint Agency Coordination Centre (JACC) announced Monday. The deep water detector, or towfish, was lost after it hit an underwater volcano and sunk to the ocean floor Sunday.

The device was being towed by the search vessel Fugro Discovery, which had returned to the search area in the southern Indian Ocean on Jan. 20 after being serviced at Fremont, Australia.
