Sub-surface search for MH370 black box underway as more aircraft mobilized
An underwater search is now underway for the flight data recorder of missing Malaysia Airlines flight MH370.
A Chinese ship is joining an Australian submarine in the first sub-surface search for the flight's so-called black box.
Angus Houston, head of a joint agency coordinating the search in Perth, says today's search area has been refined based on updated analysis of images and other data.
"The towed pinger has been deployed today on Ocean Shield. The search is currently ongoing and of course it's not just Ocean Shield that's doing the search with a towed pinger but HMS Echo, the British Oceanographic ship which is coming on a converging course over a 240 kilometre track and it has good equipment for finding things on the floor of the Ocean."
The hunt for MH370's black-box comes even as search crews have yet to find any definative signs of the missing flight in nearly 4-weeks of searching.
The batteries of an airplane's black-box generally run out after around a month, which is adding urgency to the search for the airliner's flight-data recorder.
As the underwater search begins, more planes are being added to the surface search in the southern Indian Ocean.
An additional three civilian aircraft have been mobilized to help assist in the search for any signs of MH370, which disappeared March 8th with 239-passangers and crew onboard.
