关于海巡号听到的声音，Angus Houston是这么说的：Some of the false leads that we've had actually had been the transmission

from the ship that was actually searching, and it got its own transmissions back again.

Closing in: Ocean Shield detects two more signals in search for MH370

Posted 18 minutes ago | Updated 7 minutes ago

An Australian search vessel has picked up two more signals from what could be the black box from missing Malaysia Airlines flight MH370.

The man in charge of the search, retired Air Chief Marshal Angus Houston, said the Ocean Shield picked up the traces on Tuesday afternoon and late on Tuesday night Perth time.

He said he now believed the search was closing in on the area of MH370's "final resting place".

"Hopefully with lots of transmissions we'll have a tight, small area and hopefully in a matter of days we will be able to find something on the bottom that might confirm that this is the last resting place of MH370," he said.

More to come.
