News Contact lost with 777-200ER of Malaysia Airlines

[ISProgram]

The transcript's been released...

From here:

I find it interesting that there was a discrepancy between the actual words said by the copilot and what was reported (Goodnight, Malaysian Three Seven Zero vs. All Right, Good Night).

I think if one reinterprets what the copilot actually said, there might be a small chance he played a intentional and deliberate role in the disappearance of the plane. Not like you guys haven't come to that theory anyways...

Malaysia's seriously losing any credibility it currently has...

As predicted, all of the floating junk found so far is just random junk.

Someone should call Robert Redford, you could make a good story out of this.:lol:
"For days we were looking for wreckage on the ocean only to realize...everything we ever threw away is in the ocean."

Really I say, the coverage shown on this forum on the case of the plane is a lot more complete than that available in the media of my country and I read online. This forum is the only medium where I find scientific information and more accurate data:thumbup:.

Reddit found a thing that doesn't mean anything.

Because we have people on here who are actually have an idea of how airplanes work versus.. well.. you know.

The chinese coast guard cutter "Haijing 1001" has picked up a modulated sound at 37.5 kHz, the frequency commonly used for the sonar beacons of Black Boxes, while searching in the southern Indian Ocean.

The BBC is covering this now, I have to wonder if its for real though:

A Chinese ship searching for the missing Malaysia Airlines plane in the southern Indian Ocean has picked up a pulse signal, Chinese media say.

They say the signal has a frequency of 37.5kHz - the same as those emitted by the flight recorders.

However there is no evidence so far that it is linked to MH370.

Dozens of ships and planes have joined the search, with the operation moving into its most intensive phase before batteries on the data recorders fade.

On Saturday the Haixun 01 - one of two Chinese ships in the area - picked up the signal at about 25 degrees south latitude and 101 degrees east longitude, the state-run Xinhua news agency said.

"It is yet to be established whether it is related to the missing jet," it cautioned.

China's Liberation Daily reported that three people on board had heard the signals, which were not recorded as they came suddenly.

Surely if it is one of the black boxes the signal will still be there so they can go back and just record it.

 

[Urwumpe]

Surely if it is one of the black boxes the signal will still be there so they can go back and just record it.

Its a bit harder, since the acoustics in the ocean are pretty complex, but it is a very good sign, that the black box is nearby and alive - only very few other things could produce such a signal.

You can really hear a signal shortly for a few seconds, and then never find it again, because the conditions in the ocean changed and the sound reaches the surface a few hundred meters away from your position.

If the signal was real. Remember that the Chinese have been seeing debris for weeks.

We have a new map though.......

The Australian ship "Ocean Shield" has also picked up 37.5 kHz signals, but at two different locations.

That sounds suspicious to me too.

[Urwumpe]

Again, it is not unusual for sonar:

Thats an example of a sound source in the SOFAR channel, a region where ocean water has minimal speed of sound inside it.

If the sound source would be below the "thermocline", you could only record weak sounds on the surface and that only in small spots where the sound can penetrate the thermocline, for example after bouncing back from the ocean floor after being reflected by the thermocline.

 

[Artlav]

Thermocline?
I thought the sounds are picked up by the underwater towed buoys, located well below that?

 

[Urwumpe]

Thermocline?
I thought the sounds are picked up by the underwater towed buoys, located well below that?

In such latitudes the thermocline can be as deep as 1000 meters - that is very hard to reach by towed sonar (since the cable length is usually limited to about 2 kilometers).

 

[garyw]

Thermocline?
I thought the sounds are picked up by the underwater towed buoys, located well below that?

No towed array, it was picked up by a Chinese SAR ship. How they picked it up isn't known but another ship with a proper towed sonar array is heading there now.

The batteries for the black boxes are due to hit 30 days tomorrow which is the end of their rated time. It is expected that they'll stay working but the strength of the signal will probably diminish.
The batteries were due to be replaced in June as they would have reached the end of their service life then.

 

[Screamer7]

Let's hope for the best.
This riddle needs to be solved.
For two reasons, the relatives of the missing passengers, and as well for the aviation industry.

 

[Topper]

I just read that the signal has been redetected only 1.4 miles from the original signal which was detected by the Chinese ship Haixun 01, and they say that this is an "encouraging lead":

...Houston said the characteristics of the sounds reported by the Chinese are "consistent with the aircraft black box."...

[Cairan]

Remember, the "rated" operational time before replacement of the black box batteries while in standby is to be certain that if they are indeed needed in the case of a crash, they'll be able to provide the required 30 day operational period once triggered.

There is probably some juice left in those batteries, let's hope for one thing to go right in this investigation!

 

[Urwumpe]

The Australian ship Ocean Shield had 2.5 hours of contact with the Black Box before the Signal was lost. The search region for the Ocean shield has been reduced to a 3 x 3 nm square for today.

2.5 hours is a very good track, it is possible that the Black box could get tracked good enough today, to locate it by side scan sonar and ROVs even after the battery failed.
