A mini-sub hunting for Malaysian jet MH370 was Tuesday set for a second sweep of the remote Indian Ocean seabed, after aborting its first search when it encountered water deeper than its operating limits.
The unmanned submarine loaded with sonar deployed Monday night from the Australian ship Ocean Shield which has spearheaded the hunt for the Boeing 777 that vanished on March 8.
"After completing around six hours of its mission, Bluefin-21 exceeded its operating depth limit of 4,500 metres (15,000 feet) and its built in safety feature returned it to the surface," Australia's Joint Agency Coordination Centre said.
"The six hours of data gathered by the Autonomous Underwater Vehicle is currently being extracted and analysed," JACC said.
The AUV had been due to spend 16 hours collecting data. US Navy Captain Mark Matthews said the vehicle had exceeded programmed operational limits and automatically resurfaced.
"In this case the vehicle's programmed to fly 30 metres over the floor of the ocean to get a good mapping of what's beneath," he told CNN from Perth.
Charts had put the depth at 4,200-4,400 metres, he said.
"It went to 4,500 metres and once it hit that max depth, it said this is deeper than I'm programmed to be, so it aborted the mission."
Search zone adjusted
Matthews, a search and recovery expert, said the crew would now refine the task to cope with the depth encountered.
"It happened in the very far corner of the area it's searching. So they are just shifting the search box a little bit away from that deep water."
The US navy's AUV Bluefin-21 would embark on a second mission during the day, weather permitting, JACC said. Agency chief Angus Houston announced Monday the end of more than three weeks of listening for signals

I find it more disturbing that they didn't know how deep that area of the Indian Ocean really is.
damnit,, Why cant we have batteries that last more than 30 days in the Black Box?
How dare you present such a reasonable summary of science of the pinger issue? Tin foil hats are being thrown to the floor in outrage.
No — the pressure inside and out is equalized by the water seeping in as it sinks.
And as the water outside seeps in forcing all the air out it will sink floatables and all trapped inside.
Imagine how much tin foil will fly when they find the plane on the ocean floor.
By now even if they account for every piece of the plane, whackjobs will claim the CIA, Chinese , New World Order et al meticulously placed it there after secretly killing everyone at a secret location in a secret program created by the Bush family for the illuminati.
I find it disturing that this charade has gone on for so long. They must be covering up something really bad.
Those low hanging engines would be a problem and they along with the wings would probably be the first things to break off followed by the tail section — however the fuselage would likely remain mostly intact —
Remember the Ethiopian Boeing ditching in the Comoros:
The fuselage there survived mostly intact even though the plane came in at a high rate of speed because the pilot couldn’t use the flaps since he was fighting off hijackers at the time. Then he had the misfortune of the left engine hitting
coral reef below which spun the aircraft.
The pilot of the MH370 wouldn’t be hitting any coral reef, his flaps would be working, he would be coming in at a slower speed, and he would not be fighting off any hijackers because he is the hijacker, and thus his fuselage would likely be in much better shape.
No way would it have all held together. The pressure at those depths would have twisted and crushed that plane into many pieces.

Exactly right..I don’t know, but the crush depth for a submarine is about 2,000 ft I think. Can you imagine the psi on an aluminum fuselage at 10-15,000 ft? I can’t either.
Wrong.
Aliens will definitely be in the mix.
I heard the opposite.
Though I do not know whether the source was well-informed.
An airplane is not a submarine. One or two windows broken, and it would seem to have lost it’s seal.
Who is paying for the search?
Send down the trained sperm whale with a camera.
RE: Who is paying for the search?
From BBC:

EXCERPT:
But mounting a search operation on this scale, and for this length of time, does not come cheap. The bill so far probably runs to £20-25m ($33-42m), estimates Peter Roberts, senior research fellow in sea power and maritime studies at the Royal United Services Institute (Rusi).
This includes the cost of fuel, spare parts, and transporting supplies, as well as the relocation of staff - even costs such as cancelled leave can push up the final bill.
Most of the financial burden will be borne by the countries who have contributed their forces.
For example, Australia deployed a navy replenishment vessel, HMAS Success, two weeks ago. It costs AU$550,000 a day to operate, says the Department of Defence, so that comes to $7.7m ($7.2m; £4.3m) already.
And that is just a single ship. HMAS Toowoomba, which has also been involved, costs AU$380,000.
The US Department of Defense set aside $4m to help the search: between 8 and 24 March, it spent $3.2m, a spokesman told reporters in Washington.
The UK has sent a survey ship, HMS Echo, which is equipped with sensitive underwater detection equipment. The UK Ministry of Defence (MoD) is not yet putting a price tag on the British role.
“The operation to locate flight MH370 is ongoing as is the work to fully identify the costs,” the MoD told the BBC in a statement.
In the end, the cost of sending HMS Echo to the waters off Australia will be met from Treasury contingency funds, says Mr Roberts. Governments will take the costs within their budget “and accept they have to do it”.

To make a long story short — TAXPAYERS DO ( which means because the USA is involved, YOU AND I do ).
My theory is: another plane dropped some “black boxes” in this area, but flight 370 actually flew north and landed
at one of many air fields up north. What is your theory?
I had a feeling we were paying for it.
You're assuming it was a controlled attempt to ditch on the water. More likely the airplane hit the water nose first in one piece. That would still leave the wrechage of the fuselage and wings tightly grouped and limit the size of the debris field. It would be similar to that EgyptAir flight that the co-pilot dove into the sea off of Nantucket. The Navy and Coast Guard were there within hours and the debris field was limited. It was the smell of the jet fuel in the water that was the strongest evidence of the crash site.
Since it likely had fuel for another 300+ miles and there was a live pilot at the helm flying it to that location, and subsequent absence of debris from a fuselage which likely sunk intact, that is a logical assumption to make.
More likely the airplane hit the water nose first in one piece.
And how do you arrive at that assumption?? That's not how the Boeing Ethiopian airliner in the Comoros went in. The big engines there hit first and would have here.
It would be similar to that EgyptAir flight that the co-pilot dove into the sea off of Nantucket.
A dive into the ocean is not a ditch -- one is pilot suicide and the other is pilot survival.
The video of the ditching in the Comoros is all over the internet. Go watch it.
And as you do imagine how much better it would have been if the plane was being landed at a slower speed, with operable flaps, in deeper water without a coral reef, wings not tipping into the water, flown by a pilot not fighting off crazed hijackers at the time.
And the pilot of the MH370 had 5 hours of undisturbed contemplation in the cockpit to figure out how to do it successfully and swim away.
And you know both of those because...?
Because of the previous likely flight paths charted out on this map:

And the one now most likely that’s not on the map to the area where black box pings were heard — where the 811 Arc intersects the S20 Parallel — atleast 300 miles shorter to the north and east.
