Australia says cost not a concern in MH370 search

PERTH - Australia said Wednesday cost was not a concern in the search for Malaysia Airlines Flight MH370, after the mini-sub plumbing the depths of the Indian Ocean for wreckage ended its ninth mission empty-handed.

Australia is leading the multinational search for the Boeing 777 which vanished on March 8 carrying 239 people, and is bearing many of the costs of the mission expected to be the most expensive in aviation history.

"There will be some issues of costs into the future but this is not about costs," Defense Minister David Johnston told reporters in Canberra.

"We want to find this aircraft. We want to say to our friends in Malaysia and China this is not about cost, we are concerned to be seen to be helping them in a most tragic circumstance."

China, whose citizens made up two-thirds of the passengers onboard the ill-fated flight, and Malaysia are among eight countries including Australia which have committed assets to the Indian Ocean search.

But with no confirmed sightings of debris from the flight on the surface so far, the search moved underwater nearly two weeks ago and is yet to find any sign of the aircraft.

Speaking to reporters in Canberra, Prime Minister Tony Abbott said searchers still believed the plane crashed in the Indian Ocean.

"Our expert advice is that the aircraft went down somewhere in the Indian Ocean where they have identified a probable impact zone which is about 700 kilometers (435 miles) long, about 80 kilometers wide," he said.

Abbott said based on the detections from what Australia still believed was the black box recorder, an underwater search area of just under 400 square kilometers (154 square miles) was being scoured.

"We haven't finished the search, we haven't found anything yet in the area that we're searching, but the point I make is that Australia will not rest until we have done everything we humanly can to get to the bottom of this mystery," he said.

Australia's Joint Agency Coordination Centre (JACC) said the device looking for the plane on the seabed had scanned more than 80 percent of its target zone and was now on its 10th dive.

"No contacts of interest have been found to date," it said.

The torpedo-shaped autonomous underwater vehicle called a Bluefin-21 is searching an area at least 4,500 meters (15,000 feet) deep defined by a 10-kilometre radius around a detection of a signal believed to be from the plane's black box heard on April 8.

'Reasonable hope'

A surface search involving up to 10 military aircraft and 12 ships was also scheduled for Wednesday, despite suggestions last week that this effort would be scaled down in coming days.

JACC later suspended the air search activities due to bad weather, which had resulted in heavy seas and poor visibility, but said the ships would continue their work.

The visual hunt covers an area totaling about 37,948 square kilometers, some 855 kilometes northwest of Perth, JACC said.

Johnston said Australia was tracking the cost of the mission, and if the Bluefin-21 failed to spot wreckage the search would move into a new phase, but said Canberra was committed to the task.

"We move to the next phase which is a more intensive single sideband sonar type program, I suspect, but let's take advice of the experts as to where we go forward," he said.

Johnston said Australia was talking with its partners about the assets needed for the next phase of the search for the plane which mysteriously diverted en route from Kuala Lumpur to Beijing.

Abbott said Australia would not abandon the search and let down the families of the six Australians and 233 other people onboard "by likely surrendering while there is reasonable hope of finding something."

"At the moment we are conducting an underwater search with the best equipment that is currently available," he said.

"If at the end of that period, we find nothing, we are not going to abandon the search. We may well re-think the search, but we will not rest until we have done everything we can to solve this mystery." — Agence France-Presse

Chinese, Australian ships try to verify potential ‘pings’ from Malaysia jet

SYDNEY/PERTH, Australia - Chinese and Australian ships hunting for a missing Malaysia Airlines jetliner have picked up separate acoustic signals in different parts of a vast Indian Ocean search area and are trying to verify if one could be from the plane's black box recorders.

Australian search authorities said on Sunday a Chinese patrol vessel, the Haixun 01, had picked up a fleeting "ping" signal twice in recent days in waters west of Perth, near where investigators believe Malaysia Airlines Flight MH370 went down on March 8.

More planes and ships were being sent to assist in that area, but meanwhile, Australia's HMAS Ocean Shield had reported a separate "acoustic event" some 300 nautical miles away.

The Ocean Shield is carrying sophisticated U.S. Navy equipment designed to pick up signals sent from the black boxes, which may hold the key to why the aircraft ended up thousands of kilometers off course.

"We are treating each of them seriously. We need to ensure before we leave any of those areas that this does not have any connection with MH370," Retired Air Chief Marshal Angus Houston, head of the Australian agency coordinating the operation, told a media conference in Perth.

A black box detector deployed by the Haixun 01 picked up the signal with a frequency of 37.5kHz per second - the same as emitted by flight recorders - at about 25 degrees south and 101 degrees east, Xinhua reported on Saturday.

Australian search authorities said such a signal would be consistent with a black box, but both they and Xinhua stressed there was no conclusive evidence linking it to the Boeing 777.

"The 37.5kHz is the specific frequency that these locator pingers operate on," said Anish Patel, president of Sarasota, Florida-based Dukane Seacom, which made the black box locator.

"It's a very unique frequency, typically not found in background ocean noise," such as whales or other marine mammals, he told Reuters.

Southern area back in focus

Houston said analysis of earlier satellite data had again led investigators to refine the search area towards the southern part of the corridor.

"The area of the highest probability is, what we think, the southern part where Haixun 01 is operating. That is why we are really interested in the two acoustic encounters that Haixun 01 has had."

The water was around 4,500 meters (14,800 ft) deep in that part of the search area, Houston added.

Australian Prime Minister Tony Abbott said he was "hopeful but by no means certain" that the reported pulse signals were related to MH370.

"This is the most difficult search in human history. We are searching for an aircraft which is at the bottom of a very deep ocean and it is a very, very wide search area," Abbott told reporters in Tokyo, where he is on a visit.

Up to a dozen planes and 13 ships will be scouring three separate areas about 2,000 km (1,240 miles) northwest of Perth, Australia's Joint Agency Coordination Centre said on Sunday.

Sonar equipment

Authorities have not ruled out mechanical problems as a cause of the plane's disappearance, but say the evidence, including loss of communications, suggests it was deliberately diverted.

Malaysian authorities have faced heavy criticism, particularly from China, for mismanaging the search and holding back information. Most of the 227 passengers were Chinese.

Malaysia said on Saturday it had launched a formal investigation into the plane's disappearance that would include experts from Australia, the United States, China, Britain and France.

Normally, a formal air safety investigation is not launched until wreckage is found. But there have been concerns that Malaysia's informal investigations to date have lacked the legal standing of an official inquiry convened under U.N. rules.

Under International Civil Aviation Organization rules, the country where the aircraft is registered leads the investigation when the incident takes place in international waters.

Malaysian Defense Minister Hishammuddin Hussein said the investigation would comprise three groups: one would examine maintenance records, structures and systems; an "operations" group would study flight recorders, operations and meteorology; and a "medical and human factors" group would look into psychology, pathology and survival. — Reuters

Corrected satellite data shifts focus south in search for MH370 — official

PERTH — Corrected satellite data has shifted the focus for the hunt for missing Malaysia Airline Flight MH370 to the south, the head of the agency coordinating the search mission said Sunday.

"The whole of the existing search area remains the most likely area that the aircraft entered the water, but based on the new advice the southern area now has a higher priority," retired air chief marshal Angus Houston said.

The Chinese ship Haixun 01, which has detected some signals that could be from the plane's beacons, is in this more southern area of the Indian Ocean search zone. — Agence France-Presse

Biggest search yet for Malaysian jet in Indian ocean

PERTH - Four weeks after the disappearance of a Malaysia Airlines jetliner, searchers on Saturday launched the most intensive hunt yet in the southern Indian Ocean, trying to find the plane's black box recorders before their batteries run out.

Up to 10 military planes, three civilian jets and 11 ships will scour a 217,000-sq-km (88,000-sq-mile) patch of desolate ocean some 1,700 km (1,060 miles) northwest of Perth near where investigators believe the plane went down on March 8 with the loss of all 239 people on board.

"If we haven't found anything in six weeks we will continue because there are a lot of things in the aircraft that will float," Retired Air Chief Marshal Angus Houston, the head of the Australian agency coordinating the operation, told reporters.

"Eventually I think something will be found that will help us narrow the search area."

Authorities have not ruled out mechanical problems as a cause but say the evidence, including the loss of communications, suggests Flight MH370 was deliberately diverted thousands of kilometres from its scheduled route from Kuala Lumpur to Beijing.

Dozens of flights by a multinational taskforce have so far failed to turn up any trace of the plane, and investigators concede the task has been made more difficult by the lack of data.

The Boeing 777 was briefly picked up on military radar on the other side of Malaysia and analysis of subsequent hourly electronic "handshakes" exchanged with a satellite led investigators to conclude the plane crashed far off the west Australian coast hours later.

Sonar search

Sonar equipment on two ships joining the search may help find the plane's black box voice and data recorders that are key to unlocking what happened on the flight. The black box is equipped with a locator beacon that transmits "pings" when underwater, but its batteries may only last 30 days.

Australian authorities said the so-called Towed Pinger Locator will be pulled behind navy ship HMAS Ocean Shield, searching a converging course on a 240-km (150-mile) track with British hydrographic survey ship HMS Echo.

Experts have warned the Towed Pinger Locator may be of little use unless investigators can get a much better idea of exactly where the plane went into the water, because its limited range and the slow speed at which it must be pulled behind the ship mean it cannot cover large areas of ocean quickly.

"I won't even call it an area. What we are doing is we are tracking down the best estimate of the course that the aircraft was on," US Navy Captain Mark Matthews told Reuters. "It takes a couple of days on each leg so its a slow-going search."

Britain is also sending HMS Tireless, a Trafalgar-class nuclear submarine with sonar capabilities, and a Malaysian frigate was due to arrive in the search area on Saturday.

Malaysian Prime Minister Najib Razak and his Australian counterpart, Tony Abbott, this week toured RAAF Base Pearce, near Perth, from where aircrews seven countries have been operating.

"The world expects us to do our level best, and I'm very confident we will indeed show what we can do together as a group of nations; that we want to find answers, that we want to provide comfort to the families and we will not rest until answers are indeed found," Najib said.

Malaysian authorities have faced heavy criticism, particularly from China, for mismanaging the search and holding back information. Most of the 227 passengers were Chinese. — Reuters

New images show more than 100 objects in Indian Ocean that could be MH370 debris

PERTH/KUALA LUMPUR - New satellite images have revealed more than 100 objects in the southern Indian Ocean that could be debris from a Malaysian jetliner missing for 18 days with 239 people on board, Malaysia's acting transport minister said on Wednesday.

The latest sighting came as searchers stepped up efforts to find some trace of Malaysia Airlines Flight MH370, thought to have crashed on March 8 after flying thousands of miles off course.

"It must be emphasized that we cannot tell whether the potential objects are from MH370," Hishammuddin Hussein told a news conference. "Nevertheless, this is another new lead that will help direct the search operation."

The images were captured by France-based Airbus Defence & Space on Monday and showed 122 potential objects in a 400 sq km (155 sq mile) area of ocean, Hishammuddin said. The objects varied in size from one meter to 23 meters (75 ft) in length, he said.

A dozen aircraft from Australia, the United States, New Zealand, China, Japan and South Korea were once more scouring the seas some 2,500 km (1,550 miles) southwest of Perth in the hunt for wreckage on Wednesday, after bad weather the previous day forced the suspension of the search.

"The crash zone is as close to nowhere as it's possible to be but it's closer to Australia than anywhere else," Australian Prime Minister Tony Abbott said, before leading the country's parliament in a moment's silence.

"A considerable amount of debris has been sighted in the area where the flight was last recorded. Bad weather and inaccessibility has so far prevented any of it from being recovered. But we are confident that it will be."

Malaysian Prime Minister Najib Razak this week confirmed Flight MH370, which vanished while flying to Beijing from Kuala Lumpur, had crashed in the southern Indian Ocean.

Citing satellite-data analysis by British company Inmarsat, he said there was no doubt the Boeing 777 came down in one of the most remote places on Earth—an implicit admission that everyone on board had died.

Recovery of wreckage could unlock clues about why and how the plane had diverted so far off course in one of aviation's most puzzling mysteries. Theories range from a hijacking to sabotage or a possible suicide by one of the pilots, but investigators have not ruled out technical problems.

Australia, China and France have all released satellite images over the past week showing possible debris in the same general area as the latest sighting, but no confirmed wreckage has been located.

Passenger relatives distraught

An Australian navy ship returned to the area after being driven away by gale force winds and 20-meter (66 ft) waves on Tuesday, while a Chinese icebreaker and three Chinese navy vessels were now in the search zone.

Two Chinese ships were looking for a two-meter floating object spotted earlier in the day by an aircraft, China's state news agency Xinhua reported.

The United States has sent an undersea Navy drone and a high-tech black box detector which will be fitted to an Australian Defense vessel due in Perth in the coming days.

The so-called black boxes—the cockpit voice recorder and flight data recorder—record what happens during flight, but time is running out to pick up locator beacons that stop about a month after a crash due to limited battery life.

Malaysia said on Tuesday that the US "Towed Pinger Locator" would not arrive in the search area until April 5, which would give it only a few days to find the black box before the beacon battery would be expected to run out.

The prolonged and so far fruitless search and investigation have taken a toll, with dozens of distraught relatives of Chinese passengers clashing with police in Beijing on Tuesday, accusing Malaysia of "delays and deception."

Malaysia's confused initial response to the plane's disappearance and a perception of poor communications have enraged many relatives of the more than 150 Chinese passengers and have strained ties between Beijing and Kuala Lumpur.

Chinese special envoy, Zhang Yesui, met Malaysia's Najib on Wednesday and called for "unremitting efforts" to find the plane, Xinhua said.

Multinational investigation

Flight MH370 vanished from civilian radar screens less than an hour after taking off and investigators believe someone on the flight may have shut off the plane's communications systems.

Partial military radar tracking showed it turning west and re-crossing the Malay Peninsula, apparently under the control of a skilled pilot.

The air crash investigation is shaping up as one of the most costly and difficult ever. Normally, an official investigation can only begin once a crash site has been identified. That would give Malaysia power to coordinate and sift evidence.

A government source told Reuters that Malaysia would lead the investigation, but hoped other countries, especially Australia, would play a major role. —Reuters
