Rescuers are trying to narrow down the search area for the missing MH370 jetliner.
They believe it to be somewhere in the ocean West of the Australian city of Perth, where four acoustic signals were detected, which could have been produced by the plane’s flight recorder, RT reported.
However no new “pings” were heard in the past 24 hours, and the device’s battery is only designed to run for 30 days after any crash, which means it is already five days overdue.
The jet went missing shortly after taking off March 8 from Kuala Lumpur, bound for Beijing with 227 passengers and 12 crew on board.
The search operation for the plane is the most extensive in the history of aviation.
