Submersible's search for Malaysian Airlines Flight MH370 returns to site of first ‘ping’
Bluefin-21 submersible to search area where first signal presumed to be from flight recorder of missing Flight MH370 was detected
An Australian naval vessel carrying an underwater drone involved in the search for Malaysia Airlines Flight MH370 left port on Saturday on its second mission to scan part of the Indian Ocean where the longest sonar ‘ping’ was heard over a month ago.
The Ocean Shield is heading to the area where a signal was first located and heard for some two hours on April 5, about 1,600 kilometres northwest of Perth to launch the Bluefin-21 submersible.
More than two dozen countries have been involved in the hunt for the Boeing 777 that disappeared from radar shortly after taking off from Kuala Lumpur for Beijing with 239 people, mostly Chinese, on board in one of the world’s greatest aviation mysteries.
Weeks of daily searches have failed to turn up any trace of the plane, even after narrowing the area to an arc in the southern Indian Ocean. Batteries on the black box voice and data recorders have gone flat.
The search had been centred on a 314-square-kilometre area around the second ‘ping’ located and monitored for about 13 minutes on April 5, and which search authorities identified as their strongest lead.
With the search of that area complete, the focus is shifting to the area where the first, and longer, signal was detected the same day, US Navy Captain Mark Matthews told journalists at a naval base near Perth.
