Oil Analysis per JACC Media Release

Re: Oil Analysis:
Quote: I am just pointing out that they have given themselves a little room to move!

Thanks Howard Hughes - Agreed, they have left the door slightly open to revise statement, if they do a further analysis of the oil and results become relevant to the flight ~ my comment was "generalized" and not exactly as worded per JACC media release.

Wreckage moving?

encounters 1 to 3 the plane seemed to be moving south at about 1 knot
.
Maybe it was floating at some great depth or tumbling across the seabed
I really doubt this, but I'd love to hear from a maritime expert.

After a month on the bottom, it's unlikely it would still be tumbling. One would expect it to have reached a resting place. If it's floating submerged... well, that would be a remarkable accidental balance of buoyancy, if possible at all.

Best guess... anomalous sound propagation. Although, it's surprising the detection ranges implied by that. Perhaps the ping detector is more sensitive than is expected for the "specified" detection ranges. Or, perhaps the sound was caught in a duct and thus was subject to a loss less than 1/r^2 spreading and 5db/km absorption.

No expert needed: it's simple physic matter!
If anything sank, it will be less and less buoyant with the pressure increasing. Even if the cabin sank in a whole, and it opened when it crashed on seabed, I don't see anything could be buoyant at ~5000 meters: all things which might float at the sea surface are crushed by the pressure (more than 7000 psi!). Polyethylene and like have an intrinsic density > 1: porous materials with "opened bubbles" are water impregnated and those with "closed bubbles" are crunched beyond floatting possibility. Even organic things which will slowly rot (sorry for the picture...) can't become buoyant with carbon dioxide or methane gassing: CO2 is solvable in water (and if protected from water, CO2 is a liquid at this pressure), and CH4 gives hydrate.
So...

Many theories have been put forward and there has been much speculation regarding the fate and final location of MH370. We have heard various reports of the aircraft being tracked on radar (or not) and of it following differing courses at various heights. We have seen an initial and fruitless search in the South China Sea and later, based on satellite info, we saw the search area shifted to the South Indian Ocean where we heard of 'signals' being detected which caused the Malaysian & Australian governments to express their confidence that the remains of MH370 would soon be found.

But, more than seven weeks after the event, it seems that we are no closer to understanding what actually happened to MH370 and are no closer to identifying it's final location.

How can this be?

It has to be time for a fresh look at all the available data and a re-think of the whole situation starting from scratch.

Nobody knows what happened but the authorities clearly believe it ended up were they are looking and they know more than we do. The defined area has not been properly examined. If nothing is found either the search wasn't good enough or it isn't there. Time then for the next big decision.

I'm inclined to agree with Ornis that they know more than we do, either way.


So either they know it's there, by whatever means (including the pings perhaps - but they certainly have more classified info that we're not party to) and they are looking in the right place, or they know it isn't there, and are looking in the wrong place for some obscure reason to do with obfuscating the truth.


More likely the first.


In which case I believe it's highly likely it will turn up there eventually. If you want to be a conspiracy theorist then that time might be once the geopolitical issues have been mostly ironed out and it's 'safe' to find it...

Despite all the "tech" information, not one shred of evidence has emerged, in the form of wreckage, despite a vast sea search and sat imagery.

My gut feeling still says they are looking in the wrong places!!!!

Somebody should start a rethink of this mystery!

One would think that either the aircraft was carefully and skilfully ditched, or some piece of wreckage would by now have turned up on some beach. Even at a few kt of current, it would have travelled 1000-2000nm by now.

This is completely bizzare, but then AF447 would have been too if it wasn't for the ACARS messages, and would have possibly never been found.

AF447 is not in the same catagory....at least it went down on it's flightpath and wreckage was soon found.

True, but it went down out of radar range and in between radio contacts and without those automatic messages the search area would have been huge too.

Yes, but, as with MH370, initial search was conducted close to where contact was lost and along the flightpath. Large peices of wreckage were soon located including the tail fin.

What bothers me with this MH is that despite massive satellite imagery nothing relating to MH370 has yet been located. Still think the search is in the wrong place!!!

I do not think the authorities had a lot to go on with an area selected just before the black boxes were due to die!
I see it as a clutching at straw site !
I am amazed how in this day and age that a jet of this size can fly for so long undetected! Just shows that if you ever wanted to attack any of these countries they would have no clue about you!
I know that in areas if the world I have flown in Europe you only have to go 1/2 a NM off track and someone jumps down your throat!
Even in Africa you are giving constant position reports and estimates as well as talking too other aircraft so this is amazing !

Why ?
Only one satellite over the Indian Ocean used primarily for ACARs that was switched off, no radar coverage there either, limited primary radar coverage on the original route, you can disappear in Scottish airspace quite easily.

And of course flying in Africa, well you answered your own statement, they use position reports like so many places in the world because of limited radar.

As far as I am aware, ELB do not carry source ident. Perhaps this is something else ICAO should be looking at.

I don't think we will ever know....better wait for the Movie!!!

ELTs do, ULBs don't. No idea about ELBs.

MH370 did not fly near any countries for much of its flight
We don't know that; MH370's actual flight path has yet to be established as a known fact and everything is based on theory at this time.

What we do know is that 370 deviated from it's original planned route early in it's flight. This was apparently not seen as sufficiently unusual to start alarm bells ringing immediately and I would suggest that the delay in raising the alarm meant that MH370 was effectively allowed to disappear, for reasons which are as yet unknown...

I haven't yet seen anyone in the media ask the question: "When it "disappeared" and was apparently then "seen" on Air defence radar an hour later, why was no action taken to intercept and identify it?"

This is the first thing that happens in Europe, the US and most areas when an airliner "disappears" or even loses radio contact. Malaysia is said to have a very advanced Air Defence System and yet it took no action....why?

Somebody needs to discover the wonders of Google.

Yes the media asked, and yes an answer was given. Back in March according to some newspaper articles I've found... so no doubt already discussed a million times on this thread, suggest you go back a few pages and have a read.
