Malaysia airlines plane may have crashed 239 people on board #20

[time]

The Benthos locator being used by the Chinese in the photo is an American product. Ironically, I wouldn't be surprised if the Americans were using one "Made in China".

I am appreciating your humor

"I am very skeptical, along with everyone else," said Peter Goelz, former managing director of the National Transportation Safety Board. "The Chinese have not been good team players in this. Many have thought that they have been manipulating the situation."

Wow-- that's pretty gutsy to say to MSM. I appreciate the honestly.


Also, unrelated, it makes sense if the plane is found farther AWAY from Australia than the precious searches were looking because I feel that Australia would've seen the plane in their airspace if it had been THAT close to Perth.

In my fantasy world, black box detectors would be hoisted down by cranes from any source, in a number of different areas simultaneously.fwiw
Including under Arctic ice...

“It cannot be confirmed that the pulse signal detected by the Haixun 01 is related to a black box from MH370,” the news service quoted the center as saying. False alerts can be triggered by sea life, including whales, or by noise from ships.

The Chinese vessel, Haixun 01, was searching about 1,020 miles northwest of Perth, Australia, on Saturday when it picked up the pulse signal, Xinhua reported.

On Saturday, 10 military planes, 3 civilian jets and 11 ships were scheduled to search an area about 1,050 miles northwest of Perth, and the signal reported by the Chinese ship appeared to come from that area, according to coordinates provided by Xinhua.

according to the pinger manufacture there should be 2 pinger signals..IMO, if the Chinese heard only 1 then the other recorder battery has run out or something has happened to it
also, he says the pinger has a distinct sound so not to confuse it with other noises usually heard in the ocean


http://wtvr.com/2014/04/05/new-findings-may-refocus-search-for-malaysia-airlines-jet/

A China Central Television correspondent aboard the Haixun-01 (pronounced “high shuen&#8221 reported that the 37.5 kHz signal was detected on Saturday every second for 1.5 minutes.

The signal “is the standard beacon frequency” for the plane’s cockpit voice recorder and the flight data recorder, said Anish Patel, president of pinger manufacturer Dukane Seacom.

“They’re identical.”

The frequency was chosen for use in the recorders “to give that standout quality that does not get interfered with by the background noise that readily occurs in the ocean.”

But he said he would like to see more evidence. “I’d like to see some additional assets on site quickly — maybe some sonobuoys,” he said, referring to 5-inch-long (13-centimeter) sonar systems that are dropped from aircraft or ships.

And he said he was puzzled that only one signal had been detected, since each of the recorders was equipped with a pinger, which is also called a beacon.

So it's highly unlikely that the "pings" are coming from other ships or whales, dolphins, etc?

The Australian government agency coordinating the search for the missing plane said early Sunday that the electronic pulse signals reportedly detected by the Chinese ship are consistent with those of an aircraft black box.

Thank you everyone for all your posts and updates. I'm very pleased a signal may have been found today with the flight data recorders batteries nearly ready to give up although it is not the outcome we all wanted. I will post if I find out any news about future press conferences in Australia or Malaysia in the coming hours.

A new Associated press article from Australia has been posted in the last 30 minutes with all the information about this latest news.

"A Chinese ship that is part of the search effort detected a "pulse signal" in southern Indian Ocean waters, China's official Xinhua News Agency reported. Xinhua, however, said it had not yet been determined whether the signal was related to the missing plane, citing the China Maritime Search and Rescue Center.

Xinhua said a black box detector deployed by the ship, Haixun 01, picked up a signal at 37.5 kilohertz (cycles per second), the same frequency emitted by flight data recorders.

Malaysia's civil aviation chief, Azharuddin Abdul Rahman, confirmed that the frequency emitted by Flight 370's black boxes were 37.5 kilohertz and said authorities were verifying the report."

Aviation Analyst Mary Schiavo is optimistic about the pinger being heard in this CNN video

http://www.cnn.com/video/data/2.0/v...a-cctv-announcement-pinger-detection.cnn.html

Honeywell Aerospace, which made the boxes in the missing Malaysia Airlines plane, said the Underwater Acoustic Beacons on both the flight data recorder and cockpit voice recorder operate at a frequency of 37.5 kilohertz plus or minus 1 kilohertz.

If the sounds can be verified, it would reduce the search area to about 10 square kilometres, William Waldock, an expert on search and rescue who teaches accident investigation at Embry-Riddle Aeronautical University in Prescott, Arizona said.

Unmanned robot subs with sidescan sonar would then be sent into the water to try to locate the wreckage, he said.

John Goglia, a former US National Transportation Safety Board member said, "It will have to be explored. I guarantee you there are other resources being moved into the area to see if it can be verified."

I have heard the Pinger sound on CNN...still trying to locate that video and it does not sound like, what I have heard, whale noise to be

I have also read that some experts are saying the ping can be from another source.. And then I thought WHAT other source? the locator beacon sends a signal for 30 days (give or take) so unless another airplane or vessel has gone missing in the same area over the past month what else could it be?

But I could be wrong because I have read that whale noise and interference from shipping noise can create False Alerts...sigh

http://ac360.blogs.cnn.com/2014/03/28/what-black-box-pings-really-sound-like/

There's a video here from Anderson Cooper's show on CNN, you'll hear the pinging at about 1:05.

I saw that too but didn't listen to it and can't find it now. CNN and other mms said the sounds heard can only be human-made (not wildlife, etc) BUT that doesn't mean it's not a random submarine or another searching vessel.

Yes, but, they ARE officially part of the multinational search team.

Yeah, but China appears to roll a bit like the honey badger. Just sayin’…

On Saturday, Australian officials coordinating operations from Perth said 10 military planes, three civil jets and 11 ships were participating in the search over an area of about 84,000 square miles.

It was not immediately clear whether China’s patrol ship Haixun 01 was counted among those 11 ships, and Australian search coordinators have made no mention that any Chinese vessel participating in the search was equipped with a black-box pinger detector. Photos carried by Chinese press showed Chinese searchers in a small vessel lowered from the Haixun using a hand-held commercial pinger detector.

The command center spokesman would not discuss why Australian officials had made no mention that a Chinese ship also carried a pinger detector.

…

Maybe they swung by Canadian Tire and picked one up and just haven’t submitted the receipt yet. *shrug*


I wonder what the chances are that a Chinese ship could recover one or both recorders without anyone else knowing…


Oh well, if nothing else, at least they might be able to rule out this area if it turns out that they haven’t actually found anything.

 

[JerseyGirl]

Radar expert Professor Hugh Griffiths says it's difficult to see what else it could be. "A signal like that at 37.5 kilohertz and at a regular one second ping rate, it couldn't really come from anything else. It may have been weak and it may have been fleeting but there's not anything else that could make a signal like that."

The Chinese heard it on Friday. They cleared the area of all ships, went back on Saturday and heard it again.

That's been reported upthread.

I kind of hate that only China heard it.

Yes! thanks,
That is the video I have been searching for.
I wished they would have stopped taking when the pinger began to 'tock'..but we are able to hear it..
It is distinct.
