It's a race against time, as this Australian ship is fitted with a high tech black box locator supplied by the US navy.br br The towed pinger locator, as its known, uses its highly sensitive listening equipment to detect any ultrasonic signals - "pings" - emitted from aircraft flight recorders.br br It's hoped it will be able to find the black box from the Malaysia airlines jet, which disappeared on March 8th.br br Pulled underwater behind a ship, the locator operates from a depth of about 6,000 metres.br br (SOUNDBITE) (English) US NAVY SUPERVISOR OF SALVAGE AND DIVING, CAPTAIN MARK MATTHEWS SAYING:br br "Once we do get a detection with the towed pinger locator, we would then deploy the Artemis, the under water vehicle here. Its an autonomous, it's basically a robot that can be programmed to go take a sonar mapping of the debris field. So we can properly identify where all the debris is.
