Malaysia Airlines Plane "Loses Contact"

I think this too. One minute we're being told that its almost impossible in the vast and deep Indian Ocean to receive these pings because they are only powerful enough to travel a few thousand meters and the next we're told several vessels have reported them as if by a miracle.

As I understood it the ping from the data recorders was only powerful enough do help you pinpoint the recorder in the debris field itself. 3000 meter range. And yet the water depth is 4500 meters.

Some ones telling porkies somewhere,

They dangle the receiver on 3,500m of string and by some miracle they are in range. Clever, huh.

Is there an actual authoritative bit of info on this, rather than someone said?

Maybe they have not chucked one in the deeper parts to see if they can find it.

With that depth of water you'd still have to be within a few dozen kilometres, maximum, if what they originally reported as the strength of the data recorders pinger was at all accurate.

The first ship to hear the ping was a Chinese vessel which didn't use a towed array, they used surface level devices.
The Australians then dropped sonar buoys, again surface devices, whilst a ship was sent to the area.


The Chinese ship' reports were later totally discounted, as the Australians picked up their signals over 300 kilometres further away.

Which is still pretty lucky considering they originally said they were searching a huge area of the ocean with no confirmed wreckage spotted.

If their still searching in a years time, are we going to be saying "are they even looking in the right area?".

Or do they know the right area all along?

What wiki says

http://en.wikipedia.org/wiki/Underwater_locator_be...

2 - 6 kilometres.... Which must mean they must be almost on top of it to find it in 4500m depth of water.....

Doesn't stack up to me.

Signal propagation in water is a complex beast.

surely the pings arent from the plane

I dont think so. They have nothing imo . Now i dont even believe its in the sea.

Tony Abbott quoted on the 11th April by BBC

Australian leader Tony Abbott says authorities are confident that signals heard in the Indian Ocean are coming from the "black box" flight recorders of the missing Malaysia Airlines plane.

This, it is a whole science that both the UK and US spent a small fortune on mastering in the Cold War. It is a great shame that HMS Tireless or an equivalent wasn't in the areas much earlier when the box was 'live'.

I'm not convinced they even know where the area is, never mind which bit of the area to look in.

Me neither. No one has yet explained the massive slice of luck involved in suddenly searching a new area and detecting a 'signal'. The planes were originally searching over a thousand miles south west of the place where they suddenly decided to look for signals.

Never sure of wiki. Who edited, what context they are using etc. Uses terms such as "can be" etc. The link the article in wiki uses is more forthcoming.

Agree. Time will tell.

Or not, as the case may be.

Even the Express has got hold of the possibility of it having landed somewhere. Better than the almost daily cures for my (current) arthritis and (expected) dementia...lol....

[Le Mans Visitor]

Are they still activley looking for this plane, seems the news feeds have dried up.

How do they find space for it in amongst the conspirabks about Diana being murdered by a crack unit of renegade SAS directed by Phil the Greek via MI6?

Or 'luck' = data from a hunter/killer sub that is kept quiet to preserve secrecy on how good its detection kit is

Probably lots of things we are not told. And probably nothing untoward if you were to stand back and look at the whole picture with a dispassionate eye. Reading how they found the lost nukes in the med and lost submarines, there are ways and means and we are not going to get all the information spoon fed us first hand. They will not go to the internet and say "hey google experts, scan this for us and see if it is legit".

ABC is reporting that "material" washed ashore on the SE of WA has been secured by Police and that the ATSB is examining photos of it to see if it is related to the flight.

More experts checking photos - seems to be an ongoing theme.

No point reporting the fact that theys till havent found anything
