Malaysia Airlines Flight MH370 missing!

I don't think there's much more they can do to find it. Maybe continue their side scan sonar robotic sub search for a little longer but beyond that, even the location is rather tenuous as it depends on some very intricate timing calculations from the satellite that, even with a tiny margin of error, could mean they're way off by 1000's of kms. History shows that often these mysteries go on for decades before anything concrete turns up, if ever. Consider the Helderberg - to this day there are still unresolved questions about what happened. Maybe new technology and better analysis techniques will come to the fore one day, or new information will come out years down the line.
 
As someone said the other day it's like finding a needle in a haystack and they're yet to locate the haystack.
 
UNDERSEA SEARCH FOR MH370 TO EXPAND: AUSTRALIA
by Madeleine COOREY

Australia's prime minister Monday announced an expanded search across a huge swathe of seabed where Flight MH370 might have crashed seven weeks ago, admitting it is now "highly unlikely" any surface wreckage will be found.

A massive hunt for the Malaysia Airlines Boeing 777 in the southern Indian Ocean has so far yielded nothing either on the surface or below, baffling authorities who are struggling to explain the loss of the aircraft.

"I regret to say that thus far, none of our efforts in the air, on the surface, or undersea have found any wreckage," Tony Abbott said.

He added it was now "highly unlikely" authorities would find surface debris, noting that an area of more than 4.5 million square kilometres (1.5 million square miles) had been scanned from the air.

"By this stage, 52 days into the search, most material would have become waterlogged and sunk."

Flight MH370 disappeared on March 8 carrying 239 people and is believed to have crashed in the southern Indian Ocean off west Australia after mysteriously diverting from its Kuala Lumpur to Beijing journey.

Abbott said the search would now enter a new phase of intensified undersea efforts, with authorities scouring the ocean floor over an area of about 56,000 square kilometres.

"If necessary, of the entire probable impact zone which is roughly 700 kilometres by 80 kilometres," he said when asked about the extent of the search area.

The search zone has been defined by analysis of satellite data. Searchers' hopes were boosted by several detections of transmissions believed to have come from the plane's black box flight recorders before their batteries died.

But the US Navy submersible Bluefin-21, scouring a 400-square kilometre zone centred around one of these transmissions, has failed to yield results.

Abbott announced a hugely expanded underwater search involving different technology, possibly a specialised side-scan sonar.

The announcement could raise questions over the satellite data Malaysia has used to settle on the suspected Indian Ocean crash zone, said Ravikumar Madavaram, consultant for aerospace & defense at Frost & Sullivan in Malaysia.

Families of relatives, frustrated by the lack of progress, have also questioned whether the data needs to be reviewed.

"We have finished the entire Bluefin search area, so we could be searching in the wrong window. We should go back and double-check our satellite data and assumptions and expand possibilities of where it could be," said Ravikumar.

He added: "it's going to be a costly affair" after Abbott's indication of an expanded seabed search.

Abbott said the Australian government, in consultation with Malaysian authorities, was willing to engage one or more commercial companies to undertake the work.

He estimated it would cost Aus$60 million (US$55.8 million) and take six to eight months.

So far, the eight nations involved in the Indian Ocean search --Australia, New Zealand, Malaysia, Japan, South Korea, the United States, Britain and China -- have borne their own costs, but Abbott said Canberra would ask for help in funding the next stage.

Australia is working closely with Malaysia and China, whose citizens made up most of those onboard the flight, and Beijing said it would actively support the next phase.

In the meantime the Bluefin-21 and several ships would maintain the search and a team of experts in Kuala Lumpur from Malaysia, China, Australia, Britain and the US would work on refining where to look.

Abbott said authorities still had "a considerable degree of confidence" that the signals picked up were from the black box and were determined to pursue that lead.

The anguish of families has repeatedly spilled over into anger against the Malaysian government and airline for their handling of the unprecedented event -- but the lack of wreckage had them questioning the search on Monday.

Steven Wang, whose mother was on the plane, said the expansion plan suggests the search was not looking in the right place.

"But they just search the whole ocean, and it is such a big ocean, and you cannot search everywhere. It will take years," he said.

Sarah Bajc, whose American partner Philip Wood was on the flight, questioned why Australia continued to pour assets into searching in one area.

"Why not just open up the raw (satellite) data for independent review and let's see what happens?" she asked in an email to AFP.

Selamat Omar of Malaysia, whose 29-year-old son Khairul Amri Selamat was on the plane, said there were still many unknowns.

"With no sign of a crash, I have to think that my son could still be alive," he said.

What were the underwater pings from then Mr Consultant?

MALAYSIA TO LEAD PROBE INTO ILL-FATED MH70: MINISTER

A former head of Malaysia's civil aviation department will lead an investigation into a missing jet that will also include members of the US National Transportation Safety Board and other agencies, authorities said Tuesday.

Hishammuddin Hussein, Malaysia's acting transport minister, said Kok Soo Chon would head the team probing the disappearance of Malaysia Airlines flight MH370 with 239 people on board.

"The main purpose of the international investigation team is to evaluate, investigate and determine the actual cause of the incident so similar incidents could be avoided in the future," he said in a statement.

"It is imperative for the government to form this independent team of investigators which is not only competent and transparent but also highly credible."

The anguish of families, who have alleged Malaysia was hiding information, has repeatedly spilt over into angry protests against the government and airline since the Boeing 777 vanished on March 8 on a flight from Kuala Lumpur to Beijing.

Kok, who was also a former permanent representative to the Montreal-based International Civil Aviation Organisation, is expected to face a tricky task.

While family members are demanding information, investigators have no answers as to why the plane veered dramatically off course. Malaysia believes it was deliberately diverted but it is not known by whom.

Based on calculations involving the plane's speed and fuel and satellite data, investigators believe it crashed somewhere in the southern Indian Ocean west of Australia.

Asked about media reports citing an Australian firm's claim to have detected possible aircraft wreckage in the Bay of Bengal, Hishammuddin said the international search team was verifying the information.

"Need more corroboration n verification b4 we deploy assets," he said later on his Twitter account.

Malaysian media quoted Adelaide-based GeoResonance, a marine exploration company, as saying it has detected possible wreckage 5,000 km (3,125 miles) from the current search location.

The investigation body, which has already started work, has accredited representatives from the US National Transportation Safety Board, Britain's Air Accidents Investigation Branch and China's Aircraft Accident Investigation Department among other agencies.

Weeks of air and sea searching, including a deep-sea sonar scan by an unmanned mini-submarine, have found nothing.

Australia Monday announced an expanded search involving different technology across an area of about 56,000 square kilometres (22,400 sq miles).

Did they ever check where MH370 twin was and if its still in Tel Aviv as it may explain the Maldives sighting?

Were the 100% verified as being from the plane? They only ever said that they were "consistent" with a black box pinger, so not exactly conclusive.

Most "solid" lead they had i guess,fact that they received it on 33kHz seemed a bit suspect to me instead of closer to the 37.5kHz it was supposed to be at.Think the manufacturer reckoned that much shift was ok tho....1sec pulses don't seem like it would have been anything other than something man made.
I really don't think they could have got the Doppler shift sum's THAT wrong for it to be sitting N instead of S of the equator myself.

This article is worth a look at from the info coming out about the Bay of Bengal "wreckage" that's been mentioned.
http://www.cbsnews.com/news/malaysi...ance-wreckage-of-a-commercial-airliner-found/

Check out the engine image - nice echo of the APU in the tail section perhaps? - Don't really make alot of sense why it would be facing sth tho.

Interesting, but clearly whoever wrote that didn't understand the science:

By measuring the sound waves from the plane's final pings, engineers from Inmarsat were able to determine the aircraft's location relative to the satellite; it's the same effect that makes an approaching vehicle sound different to the human ear than one moving away. The analysis of this data from Inmarsat suggested the plane had travelled south, reported Pegues.

Sound waves pinging a satellite? Really?

Although it's intriguing because the original calculations suggested a north-south arc and it was only their adjustment for the miniscule variations in the signal timing interval that lead them to conclude it was on the southerly part of the arc. Bear in mind that those calculations apparently even included the estimated time the signal would take through the various components on the satellite circuitry, so plenty of margin for error. This looks like it would place it along the northern arc instead, I think, which adds to the credibility of the finding.
 
Hehe, sound waves to Inmarsat. What a hoot.

(In fairness to the writer, it might have been a tech-illiterate and over-zealous sub-editor who mangled his copy.)

This is an exciting development. Bay of Bengal. Yikes.

I thought there was also a confirmed connection with a cell tower along the southern route? That's also pretty far from the Maldives where some eyewitnesses thought that they saw something but closer to shore for a fishing boat to have noticed something. The pictures look very interesting though.
 
Australian company GeoResonance. From their website:

Subsurface exploration has never been so precise - we detect the nuclei of targeted substances.
GeoResonance Remote Sensing and On-Site Survey will delineate your deposit in weeks not years.
Any commodity. Any tenement. Anywhere.


Fascinating to see what this turns up.

My first question is, could a flight from last known position to Bay of Bengal allow for the seven Inmarsat pings? Enough time? On a phone now so can't do a rough plot.

If your interested in the doppler side of this there's been a bunch of guys crunching possibilities for a while here(in the comments section) http://tmfassociates.com/blog/2014/03/24/understanding-the-satellite-ping-conclusion/#comments

I really don't see how they could have got the northern or southern arc choice wrong as the movements N or S of the Sat will be a known & if the resulting frequency shift was higher or lower then surely it must conclude which way(closer or further from the Sat) the plane was moving,even if you thumbsuck a constant.
Over my head but its interesting to follow.

PLANES HEAD HOME AS MH370 SEARCH SCALED BACK

The intensive aerial search for surface wreckage from Flight MH370 officially ended Wednesday as the hunt was drastically scaled back with ships also moving out of the remote Indian Ocean area where the plane is believed to have gone down.

Australian authorities said the focus would transition "over the coming weeks" to a more intensified undersea search in the quest to find out what happened to the Malaysia Airlines flight with 239 people aboard that disappeared on March 8.

Eight nations have been involved in the unprecedented hunt -- Australia, New Zealand, Malaysia, Japan, South Korea, the United States, Britain and China -- with more than 300 sorties flown across a vast expanse of remote ocean looking for debris.

But with nothing to show for their efforts from scanning more than 4.5 million square kilometres (1.5 million square miles) from the air since March 18, the planes have been stood down.

"Most of the aircraft will have left by the end of today," a spokesman for the Australian-led Joint Agency Coordination Centre told AFP, although an Australian P-3 Orion would remain on standby in Perth.

The United States, Japan, New Zealand and Malaysia all confirmed that their aircraft were returning to base. There was no immediate word Wednesday from China, which accounted for most of the passengers on board.

As many as 14 ships from Australia, China and Britain were also involved in scanning the ocean surface for debris or black box signals but many of these are also pulling out.

"Some need to head back to port and refuel and give the crew a rest, others will go back to doing what they were doing for their respective nations before they joined the search," the spokesman said.

"In essence, the surface search has been scaled back. We will keep a few vessels out there and others on standby, but the large-scale air and sea search has ended."

On Monday, Australian Prime Minister Tony Abbott announced the focus would shift to an expanded underwater search across a huge swathe of seabed where the plane might have crashed, admitting it was now "highly unlikely" that any surface wreckage would be found.

The US Navy submersible Bluefin-21 has been scouring a 314-square kilometre zone centred around one of the transmissions believed to have come from the plane's black box flight recorders before their batteries died.

But it too has failed to find anything with poor weather hampering efforts on Wednesday.

Abbott said an area of up to 56,000 square kilometres of the ocean floor would be scoured in the new search with the Bluefin remaining in operation along with other technology, possibly a specialised side-scan sonar.

MALAYSIA ASSESSING POSSIBLE PLANE WRECKAGE CLAIM

The countries searching for the missing Malaysian jet are assessing a claim by a resource survey company that it found possible plane wreckage in the northern Bay of Bengal, Malaysia's defense minister said.

The location is far from where the underwater and surface search has been concentrated for weeks. Australia-based GeoResonance Pty Ltd. stressed that it is not certain it found the Malaysia Airlines plane missing since March 8, but it called for its findings to be investigated.

The company uses imaging, radiation chemistry and other technologies to search for oil, gas or mineral deposits. In hunting for Flight 370, it used the same technology to look on the ocean floor for chemical elements that would be present in a Boeing 777: aluminum, titanium, jet fuel residue and others.

GeoResonance compared multispectral images taken March 5 and 10 - before and after the plane's disappearance - and found a specific area where the data varied between those dates, it said in a statement. The location is about 190 kilometers (118 miles) south of Bangladesh.

Malaysian Defense Minister Hishammuddin Hussein said Tuesday that China and Australia were aware of the announcement. "Malaysia is working with its international partners to assess the credibility of this information," a statement from his office said.

The Joint Agency Coordination Center, which is heading up the search off Australia's west coast, dismissed the GeoResonance report, given that the arc of ocean search crews have been scouring for weeks is well south of the Bay of Bengal.

"The joint international team is satisfied that the final resting place of the missing aircraft is in the southerly portion of the search arc," the center said in a statement.

GeoResonance said it began trying to find the plane before the official search area moved to the southern Indian Ocean. "The only motivation is to help the families of the missing passengers and crew, knowing the company has the technology capable of the task," it said.

Flight 370 was carrying 239 passengers and crew from Kuala Lumpur to Beijing when it disappeared the morning of March 8. Radar tracking and communications from the cockpit showed the plane reached cruising altitude without incident, but it veered off course for unknown reasons and flew west across the Malay Peninsula.

India, Bangladesh and other countries to the north have said they never detected the plane in their airspace. The jet had contact with a satellite from British company Inmarsat for a few more hours, and investigators have concluded from that data that the flight ended in the southern Indian Ocean.

An underwater signal consistent with an aircraft's black boxes was detected in that search area off western Australia on April 8, but no conclusive evidence has been found.

GeoResonance said it gave its preliminary findings to investigators on March 31 and was surprised by a lack of response. That claim could not be confirmed.
