Sydney - An Australian ship picked up the electronic pulse matching that of a plane's black-box flight recorder for over two hours, search officials looking for a missing Malaysian airliner said Monday.
The acoustic signals picked up by the Ocean Shield are in a different part of the Indian Ocean from those reportedly monitored by a Chinese ship last week.
"The audible signal sounds to me just like an emergency locator beacon," search coordinator Angus Houston said.
He described the finding as the "most promising lead so far" in the search for Malaysia Airlines flight MH370 that disappeared on a Kuala Lumpur to Beijing flight March 8 with 239 people on board.
The Ocean Shield, which is towing a pinger locator 3,000 metres below the surface, detected a signal for two hours and 20 minutes in its first run along a 3.2-kilometre course.
On its return run there was a second series of pulses consistent with both the flight recorder and the cockpit voice recorder that lasted for an unspecified period.//Deutsche Presse Agentur
