The major reasons why not a shred of wreckage has been found, are:

1. This is the first B777 out of over 1100 built that has crashed into water - anywhere. Thus we have no real comparisons to figure out how a B777 might behave when run out of motion lotion and then ditched. They're a very robust aircraft, and trying to compare the ditching of the Airbus A320 into the Hudson is trying to compare apples with oranges.

2. I think few very people have much understanding of the sheer vastness of the Indian Ocean. This is an Ocean where you can fly for 10 hrs at 550-600mph and not see a single solitary piece of land - and very few ships. Most shipping travels between Fremantle and Singapore, Japan and China - and only a relatively few go from Fremantle to the ME and India and Europe.

3. If the aircraft ditched in the current search area (as this is still the highest possibility of all the scenarios), any wreckage will have been driven by prevailing winds and currents in a Westerly, or Sth-Westerly direction.
Some permanently buoyant wreckage will possibly be merely circulating in eddies in the mid-Indian Ocean, far beyond any current aerial search area.

Possibly 50% of the initially-floating wreckage will have sunk by now.
In time, perhaps in weeks to come, some small pieces of identifiable wreckage may appear around Mauritius, Reunion, Madagascar, or the Seychelles.
I'm personally amazed that no reward offers for MH370 wreckage, to fisherman in the regions surrounding the Indian Ocean, have been made, to assist in wreckage recovery and ID.

4. I'm of the personal opinion that the Bluefin-21's capabilities are being stretched, and that better equipment is needed.
I feel that dedicated sea-floor mapping ships would be better suited to the search for the wreckage, from here on in.

I don't own this space under my name. I should have leased it while I still could

Thinking about that screen shot.

It was heavily synthesised as the only plot was that of MH370. There must have been other plots but they appear to have been suppressed.

A simple screen shot would have shown the contact at one moment. This short was clearly a composite showing an initial track, a dark period, and then a regain until it ran out of radar range.

What caused the initial 'dark' period?

Either they had no plot for some technical reason or the aircraft was at a medium level and ran out of radar range at that level.

Contact was then gained as the aircraft was climbed to a greater altitude and finally lost at that higher altitude when it was too far from the radar site.

I am just a Aussie person, of which we normally try very hard to try and fix problems if we can. With the evidence we have at hand. But surely we should have
Some evidence. Nothing floating. I agree how hard this must be be for the workers on this job
I have had to find 1 yacht in port Phillip , Victoria Aus it took 4 hours with air support. I wish them all the best but with not :1 bit of plane ?? How long do we
Keep searching .

Interesting re debris.

Smart of the police to take and send photos

Hope they can tell from the photos but won't take long once the ATSB get hold of it.

Long way but 7 weeks is long enough and that would follow the current down the coast
which is the major current.

I think they are talking about the South Equitorial current
which is further north.

Have a look on Google.

MH370 search: 'Object of interest' found on Western Australian coast - CNN.com


Australian Transport Safety Bureau Chief Commissioner Martin Dolan described the object as appearing to be sheet metal with rivets.
"It's sufficiently interesting for us to take a look at the photographs," he said.
But Dolan also added strong words of caution: "The more we look at it, the less excited we get."
The object was picked up near Augusta, some 300 kilometers (186 miles) south of Perth, a source with the Australian Defence Force told CNN.
The source also described the object as having rivets on one side with what appears to be a fiberglass coating.
When asked about the shape and scale of the object, the source described it as "kind of rectangular," but torn and misshapen.
The source said it was too difficult to estimate the size because they had only seen one photo with no clear scale.
The object of interest is in the custody of a police agency in Western Australia. Authorities there wouldn't comment further because it's a federal investigation.

Debris

Anything resembling fibreglass on the inner fuselage of a 777?

Lack of any physical evidence. All the circumstantial evidence we have says it should be on the sea bed around where they're currently searching with the AUV, but nothing's turned up in the right place yet, on the surface or under it.

I strongly suspect it's down there somewhere, but, until something is found, people will continue to consider other possibilities.
What if the plane broke up shortly before entering the water?

That would account for the ULB pings (the black boxes are there but not the rest of the aircraft), the satellite arcs (the rest of the aircraft is nearby but just outside of the narrow search area defined by the ULB pings) and the lack of debris field (if the breakup occurred at a low altitude).

I would think it more likely to be a component in wing panels/flap covers etc

Oz or Africa

In recent years several pleasure boats which have broken their moorings in W.A., have end up on the East African coast and Madagascar.

"He said the debris appeared to be sheet metal with rivets."

It's BIG !

"Senior Sergeant Steve Principe at Busselton Police Station told The Busselton-Dunsborough Mail the object in their possession, which had washed up on a beach at Scott River near Augusta, was eight feet (2.43 metres) tall, half a metre wide and was an alloy type of metal.

I'm not actually clear whether a fiberglass coating is plausible on parts that are not structurally composite, perhaps that broadens the areas it might be from.


Reading the Boeing site as we speak..

Hmmm...let me think about this.
Something that is in the sea....and is made of fibreglass !

It's a tricky one that.

Why not wait until they say, yes, it is from MH370 and release the photo
then we can play jigsaw and work out where it fits

That's a good point.


Regarding the radar plot you posted about on the previous page, Pontius,


forgive me but is it a plot from one particular radar operator or something cobbled together from two different ones? If it was the latter that might explain the bit in the middle with no information.


I'm probably way off. I like your theory better.
