Submarine to search for the missing Boeing 777

A Bluefin-21 robot submarine is to be lowered, perhaps in a few days, on the bottom of the Indian Ocean, in the region where acoustic signals were detected, signals that could be coming from the MH370 plane, announced the Australian authorities on Tuesday.

"We should continue the signal detection for several days before the batteries discharge" and before the signal is lost, declared the head of the operations, Angus Houston.

"We need additional transmission to better in order to better define the search area," he added.

Two signals were captured during the weekend, one for two hours and 20 minutes and the other for 13 minutes. During the second detection, two distinct waves were heard, separately.

They could come from the two black boxes of the Boeing 777 aircraft belonging to Malaysia Airlines, which disappeared from the radar screens since March 8, with 239 people on board.

The signals were captured far away, on the west coast of Australia, in the Indian Ocean area, in which apparently the Boeing 777 could have crashed.

But the Australian Ocean Shield ship, equipped with signal detector, detected nothing on Monday.
