6. I don't trust a word CNN says anymore
Mon Apr 7, 2014, 12:58 AM
Apr 2014

And at this point CNN is the only outfit I can find with anything recent to say on the subject:
http://www.cnn.com/2014/04/06/world/asia/malaysia-airlines-plane/

And that is just a rehash of the 2-day-old Chinese reports that have not been confirmed as far as I can tell, together with CNN's usual bullshit speculation.

I love this one. One guy is arguing that the plane was carefully guided in such a way as to avoid Malaysian radar. If you are going to crash the plane in the ocean, why do you care if anybody sees you on radar? It won't make a bit of difference.

And then another guy chimes in with, "On no, that is hogwash because there are all sorts of other radars there. That's a stupid theory. What really happened was that the plane was running away from another aircraft that was trying to shoot it down."

OK, he didn't say it exactly that way. here's what he said:

"I think the plane's being intentionally flown there, but I think it's still a mystery as to why. ... I think they would probably guess they're not avoiding anybody's radar, because there's a lot of radar in the area," he said. "I think they're avoiding getting shot down or colliding with another airplane."

I am getting to really hate these dumbasses.

Kuala Lumpur, Malaysia (CNN) - After a month of searching, investigators now have their "most promising" lead yet in finding Malaysia Airlines Flight

A pinger locator in the Indian Ocean has detected signals consistent with those emitted by aircraft black boxes, the head of the Joint Agency Coordination Center said Monday.

The sounds were heard at a depth of 4,500 meters (about 14,764 feet), retired Air Chief Marshal Angus Houston said.

"We've got a visual indication on a screen, and we've also got an audible signal. And the audible signal sounds to me just like an emergency locator beacon," Houston said.

Mon Apr 7, 2014, 01:41 AM
Apr 2014

200 km apart, so they can't both be right.

We now return you to the CNN 24-hour groundless speculation network for their regular diet of unfounded theories, invented "what if" facts, and irresponsible headlines.

If the Australians have actually found the pingers, then it shouldn't be any problem for one of the ships with more sensitive instrumentation to arrive on the scene on Monday North American time to confirm that.

This gives CNN a real dilemma. Should they continue their groundless speculation abut the "Chinese discovery" or should they instead switch full time to groundless speculation about the Australian findings? Aw what the hell, why not do both? Three is plenty of cable time to fill.

Mon Apr 7, 2014, 10:33 AM
Apr 2014

The plane could not have broken up and had parts separated by 600 km and you can't hear the ping 600 km away.

The stuff couldn't have drifted that far apart or else there would have been plenty of debris on the surface to find by now. The absence of debris suggests that the plane didn't break up into a million pieces.

The fact that somebody could draw a ling between two points is not really much of a breakthrough, I don't think.

They have precise GPS coordinates of both locations, They should be able to get ships out there to both sites to confirm that within the next 24 hours. The complete absence of other reports providing more tangible information suggests to me another over-hypes CNN wild goose chase.

27. They are still triangulating
Mon Apr 7, 2014, 11:39 AM
Apr 2014

The aim is to use triangulation to pinpoint the location of whatever is transmitting the pings, according to Cmdr. William Marks of the U.S. 7th Fleet. "For us in the Navy, this is kind of our bread and butter," he told CNN.

The crew of the ship does this by towing the pinger locator along a series of intersecting lines across a relatively small area of ocean.

If the sound is picked up along three different lines that cross at the same point, "that's a pretty positive indication of where the signal's coming from," Marks said.

But it's a slow and painstaking business. By the end of its runs Tuesday, Ocean Shield expects to have thoroughly covered only a 3-mile-by-3-mile box, according to Leavy.

Each run across the area takes the ship seven to eight hours. That's because it's moving slowly -- at about 3 knots (3.5 mph) -- and because turning around with the huge length of cable that's dragging the pinger locator through the ocean depths is a delicate, drawn-out process.

31. maybe not
Mon Apr 7, 2014, 06:05 PM
Apr 2014

Apparently the signals can be "moved" by conditions of the water reflecting the ping off the ocean floor...

"The black box may be giving off pings from the ocean floor. But if those pings hit a layer of warmer or colder water above, the signal might be refracted or reflected."

http://www.bbc.com/news/magazine-26721975

It doesn't say how far signals could be refracted/reflected off the ocean floor, so who knows, maybe that was what the Chinese vessel picked up. Or maybe they picked up something that was of the right frequency but was something else though I have no idea what the something else could be.

I think the Australian signal pick up is more promising given that it was stronger, lasted a lot longer and 2 signals were picked up simultaneously by that special towed search device. Seeing as there are two black boxes giving off identical signals, that sounds particularly promising.

I don't know if CNN said they actually found the black boxes or not. The statements from authorities were very careful in saying that they don't know yet but that it is the most promising lead thus far. It could be just an overblown OP title that CNN never actually said since there is no link to CNN saying such a thing.

I'll go with the cautious statements from the Australian authorities rather than any over hyped news reports from any network particularly seeing as they've been making an over hyped botch of everything about this story from the beginning.

It it were a very low frequency (i.e. whale range) I would be more of a believer.

It seems to me that if they have actually found the things, there would be more than just a few moments of recognition, assuming that the pingers are not moving.

37. no one but the OP is saying they were found
Mon Apr 7, 2014, 07:46 PM
Apr 2014

And the 37.5 frequency was chosen specifically because it doesn't sound like anything else naturally in the ocean. It isn't just the frequency either but the pulse timing - once every second.

Have you actually read anything about this discovery? The Australian ship towing the underwater search device found and held the "ping" for about 2 and 1/2 hours, lost it when they moved too far away, turned around and went back picking it up again in the same place for about 13 minutes when they picked up simultaneous identical pings from two sources which makes it seem reasonable that both black boxes were being picked up at the same time in the same place.

I'll go with what the experts have been saying about it.

If they are right over it, and they should be at this point, then they should be able to positively identify it rather shortly. It shouldn't take 4 days to confirm that.

Perhaps they are just being ultra-conservative, given all the false hopes they have thrown out along the way. We are well into Tuesday's daylight hours on the scene now. If it goes another day without a certain identification, that will not be a good sign.

on the weekend was troublesome. And since that time we are 3 days without any hint of a signal, apparently.
http://www.chicagotribune.com/news/chi-malaysia-plane-20140408,0,4089528.story

This is not good. I don't know what the failure profile looks like on these devices. If I were designing it, I would include circuitry to space out the pings once battery capacity got to 50% and keep making the pings less and less frequent to try to get the longest possible time with some pings. But I don't see any indication this is how the boxes are designed. Nonetheless, it is implausible that they had two separate strong signals on the weekend and then they both decided to die at that same instant.

Mon Apr 7, 2014, 10:44 AM
Apr 2014

It is a natural inclination of governments to find a scapegoat. And a dead scapegoat is even better because he cannot refute it.

It is absurd to think that:

a) A person intent on crashing the plane would just fly it until the fuel ran out. Why wait that long and take the chance that somebody would intervene. You wold just crash the plane straightaway.

b) A person intent on crashing the plane would execute a complex plan to avoid radar at all, because what difference would any of that make. If the guy had control of the plane, no radar could stop you from crashing it.

They are mixing up their conspiracy theories. If the plane was landed on a remote island US base run by Somalian pirates in order to let al Queda load it full of explosives and crash it into a tower, yes, in that case it would make sense to avoid radar. But that isn't where the pings came from.

Mon Apr 7, 2014, 10:53 AM
Apr 2014

The reported said the voice recorder will reveal the pilots' conversations. The VDR loops, and some of these only have enough storage for the last 30 minutes. It seems probable that there was nobody alive at that time, so I doubt the VDR will reveal much. The flight data recorder should show the final settings, and could probably reveal a lot about how the navigation was set up and if there were any systems that were extremely damaged.

they are able to salvage much of the plane. That wasn't the point.

The point was that there are a lot of families who don't know where their relatives ended up. Now they know where and that there is no hope. It will take a long time to find out how, if ever.

30. "If"
Mon Apr 7, 2014, 01:35 PM
Apr 2014

There have been about 50 false starts, and they all sounded equally promising. In fact they use practically the same language to introduce each one: "This is the most promising lead yet ..."

I hope this one turns out a lot better than the last 20.

As far as the reconstruction, anything they find could yield important clues.

If the voice data recorder actually shows pilots talking in the last 30 minutes, that would surely settle the big questions. I doubt that will be the case though. IF there isn't pilot talk, then they will want to find out if the aircraft was damaged, and that should show up in the data recorder, even if it only had the last hour of flight.

38. the last two hours with this plane
Mon Apr 7, 2014, 08:08 PM
Apr 2014
http://www.bbc.com/news/magazine-26721975

"The cockpit voice recorder continually records over itself as the flight goes on. US firm Honeywell Aerospace says the black box on the missing airliner - which it provided - only retains two hours of recording. That's the length of time that regulations demand. The principle is in place because it is normally the last section of a flight that determines the cause of the crash. But in the case of the Malaysia Airlines 777 it might well be the case that the key events happened long before the actual crash."

But it isn't the cockpit recorder that is likely to reveal much if any information but the data recorder.

The data recorder doesn't record over itself but retains the information of the entire flight.

http://www.wisegeek.com/what-is-a-flight-data-recorder.htm

Examination of the wreckage itself is likely what will reveal the most information just like most other plane crashes. But that's also what the black boxes are for - to find the bulk of the aircraft particularly when it's in water.

Statement from coordinator of hunt for missing jet
“Today I can report some very encouraging information which has unfolded over the last 24 hours. The towed pinger locator deployed from the Australian defense vessel Ocean Shield has detected signals consistent with those emitted by aircraft black boxes.

“Two separate signal detections have occurred within the northern part of the defined search area. The first detection was held for approximately 2 hours and 20 minutes. The ship then lost contact before conducting a turn and attempting to re-acquire the signal.

“The second detection on the return leg was held for approximately 13 minutes. On this occasion, two distinct pinger returns were audible. Significantly, this would be consistent with transmissions from both the flight data recorder and the cockpit voice recorder.

“Clearly, this is a most promising lead. And probably in the search so far, it’s probably the best information that we have had.

If the plane disintegrated, there should be a lot of floating debris and at least a few floating bodies by now, and they have found zero. If those are the real pingers, I bet the plan landed mostly intact and sank as a unit.
