Not quite sure where the current best estimate of crash position is but it seems to be at about 30 degrees South, 97 degrees East.

So not in roaring forties and not in the dark at 8:11am Malaysian time.

I would add to the above comment that it is unlikely that you could ditch a 777 in the open ocean which is subject to large swells without it breaking up on impact.
An ocean is very different surface to land on compared to a river....such as the Hudson.

On another topic:
I suspect Freescale is just "bigging up" the status of their 20 employees lost in the accident. They were probably just general workers rather than key executives/dept heads.
If one of our employees was lost then I expect my company would start pumping out the PR about how essential they were and how it was a tragic loss and how we are all devastated: yeah I'll bet. Meanwhile back at the ranch the other employees would have already put in their CV's for the post and the company would actually be wondering whether we could do without the positions anyway.

Bono, if you look at the grey underlay you will see that it shows track coverage of the whole area but with gaps.

It is standard search procedure to set out post-flight the actual areas searched. Subsequent searches will thentry and cover the gaps.

The yellow overlay is the total area and when that is searched further gaps will appear.

Now we know in this case that the geographical location of those gaps moves hour by hour so really it is luck if you don't miss any on the refly.

Following a ditching, wouldn't the aircraft structure be subject to very high pressures as it sank?
This would surely at some point cause disruption to the fuselage permitting some buoyant objects to spill out and find their way to the surface?

Admittedly in much smaller quantities than with a high speed impact.

I haven't seen any posts related to the aircraft being within range of Singapore radar. What did I miss?

Just going back to the change in phraseology used in the last RT transmission..

How on earth can it have taken 3 weeks for this info to be clarified? Who listened to the ATC tape initially and why was the false information published?

I was thinking the same thing ETOPS. For weeks we have people commenting on what the use of 'all right, good night' could mean. Nearly all of the conclusions were rubbish. Now we find out the final transmission was something a little different. Not that it makes much difference.

But like you said, why has it taken weeks for this information to be realised?

XUE LONG

Been watching the marinetraffic.com website for the last few days and notice the XUE LONG was slowly moving out of the search area and now its off the coast of Karratha and its destination is CN SHA looks like its going back home at a steady speed of 15.3 knots.

Ok my post disappeared as usual,

I'll re-phrase..Malaysia Airlines is majority owned by the Government of Malaysia and the Captain was a supporter of the opposition leader who has recently been reconvicted of a made up crime, and the Captain was present at the court case, and also recently divorced. So maybe in a state that wasn't conducive to work..

Whilst your question is valid for the public at large, do you suppose that this is new information to the authorities?

Further to my post about the XUE LONG leaving the search area and currently off the coast of Karratha and heading back north, I notice there is a Chinese search vessel HAI XUN 31 moving around Christmas Island.

Is there something going on around there? One vessel searching and another heading there way?

Let us not loose sight of the fact that the current possible location is based on a mathematical extraction of the Inmarsat data (as the data itself contains no pinpointing reference) combined with an estimation of fuel endurance.

Nothing else that we are aware of except the fact that the aircraft has not been located anywhere else.

I find the lack of debris in the areas that have been searched to indicate that the plane did not crash there
I guess I'm not the only one to have the nagging feeling - exactly as I stated, when the first search area turned up nothing - that they were looking in the wrong place - and, as this search area has turned up exactly nothing, the logical conclusion is - the search is still in the wrong place.

Please show me the past aircraft crashes onto the open ocean surface, where no damage was done, and no debris was left floating.

The basic problem is the sheer paucity of real information such as speed and altitude in the last sector of the flight path.
The aircraft could have ditched 200NM further North, or gone 200NM further South than the initial search area.
I'm of the opinion a lot more work needs to go into pulling together any of the smallest shreds of evidence, that could produce a more precise definition of the actual flight path.

Perhaps a "convention" is needed, where all the experts get brought together to have a serious "idea-bashing" meeting - which might produce better results, than individual agencies working alone and independently.

Primary Radar Coverage

Is there any way anyone could possibly have known how poor/switched off the primary radar coverage for that part of Asia and Australia (especially considering all the hype regarding JORN) actually was, prior to this event?

It is normal practice to give POB and registration in many parts of the world (it confirms the billing process!) Certain areas require more information. "security check complete, ADC number xxx, etc."

It is not too unusual to repeat the FL350 Level call if you think you may have forgotten it. It was 0108 local time after all!

Sir Richard

Thanks.
I remember situations where I did repeat report messages ; they involved higher-than-normal stress level.

NoD - All I'm stating is that comparing a crash on a calm icy river with an Airbus as against a crash on a windy open ocean with swell and waves with a 777, is the equivalent of comparing apples with oranges. We have no ditching crash record for a 777 to refer to for comparison. We have a crash into a seawall, and that crash showed us the 777 is built like a tank - but it still can't be compared to a ditching for comparison purposes.

Somewhere out there, there's some identifiable pieces of MH370 wreckage, and they will almost certainly appear in the next few weeks.
It just needs a particularly alert person, and the right circumstances. It will probably be a fisherman.

How many times have people found a critical item that was being searched for, that couldn't be found - despite thorough searches being carried out - and the finder found it by pure accident, by looking at the right place, at the right time, in the right light?

I think nearly everbody expected,that some debris would have been found after 3 weeks.Somehow the mystery deepens.
This is truly an extraordinaire accident,we still have 3 possibilties :
1.Technical faillure
2.Pilot action/suicide
3.Third party

Maybe we shall think about an event nearly already forgotten, ca. 3 weeks before MH370 we had those mysteries fires on the airline with know name.
The culprit was still onboard,when thea/c landed in DXB.
Sometime i think it`s to much coindience,two unusual events in such a short time in the same region.

The fewer the number of pieces of wreckage on impacting the water, the lower the chances of discovery. Even a bad ditching in the dreaded 'roaring forties' may only result in a few pieces of wreckage; a wing, a tail an engine, etc., compared with hundreds of pieces from a high speed impact. It's also well outside any expected search area. Anyone planning this is unlikely to have known about the ACARS pings, much less the doppler effects resolving the ambiguity of direction. Finessing the ditching is rather irrelevant to someone planning this. Suiciding prior to impact does dramatically increase the chances of discovery due to the fragmentation of the aircraft, but this does involving guessing the perpetrator's mindset.

The same scenario in other optional ocean regions involves a far greater chance of eventual discovery because of greater radar coverage and much shallower water.
