Missing Malaysian jet news (1 Viewer)

I am so confused
Investigators reveal MH370 co-pilot tried to make a call from his mobile phone after the aircraft 'vanished' but 'was abruptly cut off' as U.S. deny reports the plane landed at their remote military base
The co-pilot of missing flight MH370 made a call from his mobile phone while the aircraft flew low over the west coast of Malaysia, it was revealed today as the U.S. denied reports the plane landed at a military base on the remote island of Diego Garcia.

Investigators have learned that the call was made from Fariq Abdul Hamid's mobile phone as the Boeing 777 flew low near the island of Penang, on the north of Malaysia's west coast.

The New Straits Times reported the aircraft, with 239 people on board, was flying low enough for the nearest telecommunications tower to pick up Fariq's signal.

The call ended abrupty, however it has been learned that contact was definitely established with a telecommunications sub-station in Penang state.

The paper said it had been unable to ascertain who Fariq was trying to call 'as sources chose not to divulge details of the investigation.'

It added: 'The telco's (telecommunications company's) tower established the call that he was trying to make.

'On why the call was cut off, it was likely because the aircraft was fast moving away from the tower and had not come under the coverage of the next one,' the paper said, quoting 'sources'.

The plot thickens....
That is the last thing I think I would have expected to hear at this point. I figured they were all dead after communications were lost

:oldunsure:
It has been pretty clear for a while the pilot did it. The question is who the #### did he call?
Ahhhh but Malaysia is taking back that all passengers have been cleared message they made awhile back. Now everyone is being investigated, again. :coffee:

It was from the co-pilots phone. I suppose it's misleading since it could have been anyone using his phone. I don't know. Who knows besides the aliens that abducted all of them.

 
What doesn't make sense to me is that the ping is broadcast at such a high frequency (37.5 kHz). The higher the frequency, the higher the absorption loses. In fact a lot higher. Even signals broadcast very loud (160 dB) can get absorbed somewhat quickly within a few miles. It makes more sense to broadcast a lower frequency at a lower decibel level if you are hoping to track it over a very long distant.

 
has the FFA settled this thing and indicted the proper people?

are we calling this a conspiracy theory by the clearly inept Malaysian government and have we declared war on them yet? should the political leaders be jailed? executed? both?

we all know that they should have had this thing solved within seconds and the failure to do so means they are criminal

GET ME SOME ROPE!

Not really criminal. This is what you get when you have Barney Fife running an investigation. No offense. ;)

I hear somewhere it was because nothing else on Earth, man made or natural used that frequency

It still makes no sense. After a few miles, the most sensitive equipment is not going to be able to pick it up. Other frequencies would travel much further and could overcome background noises and still be detected.

It's not our fault. It took days to solve the Boston bombings. We've been conditioned.

 
It's getting to the interesting part. They'll deploy these submergibles and search within the area they determined it was based on the iffy pings they heard last week. If they come up empty, the search will essentially be off. Just watch the conspiracy theorists then., And the passengers' families will go into riot mode.

But what good is the ping if hearing it doesn't allow you to narrow down the search area?

"The good news is we hear the ping - the bad news is that we only know it's within 200 miles of our search vessel." :shrug:

 
I wonder if this event will change the way black boxes and such function. Seems like making them so that they can spit out easily-traceable GPS coordinates from the bottom of the Marianas Trench -- and do it for 5 years or so -- would be highly desirable. This is a one-in-a-zillion event, though ... any changes would have to be cheap.

I think you just negated the possibility.

???? The loudness of the signal at the reciever will give a good indication of how far away the transmitter is. You know how loud the signal is at the source should be, you know how loud the signal at the reciever is. It is pretty simple task to determine the distance the signal has traveled if you know the properties of the air or water it is travelling in. The longer range of the sound would also make it easier to triangulate on the box and locate it. It makes very little sense to use that high of a frequency since it severely limits the range at which it could be detected.

 
So has everyone but CNN moved on? They have kinda hitched their wagon to this plane story. At this point with all the time and $ wasted, just give up and wait for some debris to arrive on shore somewhere.

We either have a murder or terrorist attack which killed over 200 people or we have a dangerous problem on an aircraft which endangers tens of thousands of people everyday. Either way it is important to get issue to get to the bottom of.

If I designed the black box transmitter it would have been solved a long time ago.

A little dramatic, don't you think? The law of "things that happen sometimes" dictates that occasionally something goes wrong with a mechanical device, airplanes included. And the terrorist bent? Come on...

As a whole we are more anal about aircraft safety than other vehicles. It is proably due to a couple reasons. First because airplane accidents get massive news coverage. And secondly, people need more assurance when they fly than when they take ground transportation.

If only we had turned to you. Alas.

So what's your ETA for resolving this current state of affairs? You keep telling us it's easy, there's a way to do it. And I believe you.

How long?

A U.S. official with firsthand knowledge of the investigation into the disappearance of Malaysia Airlines Flight 370 told CNN's Pamela Brown today that a cell phone tower in Penang, Malaysia -- about 250 miles from where the flight disappeared -- detected the co-pilot's phone searching for service around the time the plane vanished.The revelation follows reporting over the weekend in a Malaysian newspaper that co-pilot Fariq Abdul Hamid had tried to make a telephone call while the plane was in flight. However, the U.S. official -- who cited information shared by Malaysian investigators -- said there was no evidence the co-pilot had tried to make a call.

The details do appear to reaffirm suggestions based on radar and satellite data that the plane turned around and was likely flying low enough to obtain a signal from a cell tower, the official said.

Apparently they should have turned to me. It is a horrible design to locate in a deep area of the ocean. A lower frequency ping would have been found a long time ago. Now it is impossible if the battery is dead, which it most likely is. They will have to stumble across the wreckage on the ocean floor.

You know what they should get - a big ### magnet, attach it to a plane and fly over the search area - it will pull the plane from the bottom of the ocean. I'm sure of it.

Sometimes #### just happens.

People need to realize that no amount of planning, design, security, or foresight can prevent #### from happening sometimes.

 
I just looked at the specs for those acoustic beacons. The guys on CNN kept going on how loud they were, 160 dB. They described the noise as if it would be as loud as a gunshot. What those CNN 'experts' (or misinformation idiots more accurately) don't realize is the specifications for those beacons don't use the typical 20uPa as reference, but 1uPa for their dB calculation. Yeah, it they used the 20uPa as the reference dB it would be equivalent of the sound pressure level of a gun shot. But because it used 1uPa as a reference, it is more equivalent to a whisper at 34 dB. It is no wonder the damn thing is so hard to find. It not only transmits at a high frequency which gets killed by attenuation, it is only transmitting at the level of a whisper (assuming our ears would be capable of hearing such a high frequency, which we are not).
