Yet searchers have still not found a single piece of physical evidence such as wreckage or human remains. But repeated searches by a robotic submarine have so far failed to find the source of the pings, which experts say could have come from marine animals or even from the searching ships themselves.
There remains only one publically available piece of evidence linking the plane to the southern Indian Ocean: Yet independent experts who have analyzed the report say that it is riddled with inconsistencies and that the data it presents to justify its conclusion appears to have been fudged. For the first few days after MH disappeared, no one had any idea what might have happened to the plane after it left Malaysian radar coverage around 2: In all, a total of eight pings were exchanged.
Each ping conveyed only a tiny amount of data: Taken together, these tiny pieces of information made it possible to narrow down the range of possible routes that the plane might have taken. If the plane was presumed to have traveled to the south at a steady knots, for instance, then Inmarsat could trace a curving route that wound up deep in the Indian Ocean southwest of Perth, Australia.
The problem with this kind of analysis is that, taken by themselves, the ping data are ambiguous. Given a presumed starting point, any reconstructed route could have headed off in either direction.
A plane following the speed and heading to arrive at the southern search area could have also headed to the north and wound up in Kazakhstan. Why, then, were investigators scouring the south and not the north? The March 25 report stated that Inmarsat had used a new kind of mathematical analysis to rule out a northern route.
See the chart at the top of the post. One line on the graph showed the predicted Doppler shift for a plane traveling along a northern route; another line showed the predicted Doppler shift for a plane flying along a southern route. A third line, showing the actual data received by Inmarsat, matched the southern route almost perfectly, and looked markedly different from the northern route. The report did not explicitly enumerate the three data points for each ping, but around the world, enthusiasts from a variety of disciplines threw themselves into reverse-engineering that original data out of the charts and diagrams in the report.
With this information in hand, they believed, it would be possible to construct any number of possible routes and check the assertion that the plane must have flown to the south.
Unfortunately, it soon became clear that Inmarsat had presented its data in a way that made this goal impossible: He found, however, that no matter how he tried, he could not get his values to match those implied by the possible routes shown on Page 3 of the annex. According to the March 25 report, Inmarsat teased out the small differences predicted to exist between the Doppler shift values between the northern and southern routes.
And yet Page 2 of the annex shows a radically different set of values between the northern and southern routes.
Its engineers are widely regarded as top-drawer, paragons of meticulousness in confjdential industry that is obsessive about attention to detail. But confidwntial work has been presented to the public by authorities whose inconsistency and lack of transparency have time and again undermined public confidence. What frustrated, grieving family members need from the authorities is clarity and trustworthiness, not a smokescreen.
Inmarsat has not replied to my request for a clarification of their methods. It would be nice if Inmarsat would throw open its spreadsheets and help resolve the issue right now, but that could be too much to expect.
Inmarsat may be bound by confidentiality agreements with its customers, not to mention U. The Malaysian authorities, however, can release what they want to—and they seem to be shifting their stance toward openness. After long resisting pressure to release the air traffic control transcript, they eventually relented. Now acting transport minister Hishammuddin Hussein says that if and when the black boxes are found, their data will be released to the public.
With the search for surface debris winding down, the mystery of MH is looking more impenetrable by the moment. If the effort to find the plane using an underwater robot comes up empty, then there should be a long and sustained call for the Malaysian authorities to reveal their data and explain exactly how they came to their conclusions.
This is a cross-posting of an article that was published on Slate. You can read the original here.
It involves directing a signal at the ionisphere, deflecting back onto the earth surface, then back up to the ionisphere, then back to where it was sent. Confidntial gives us the ability to monitor pretty much what we want to in a huge arc. But it was never intended to give us real time surveillance over that whole area — in the direction of Inmmarsat in the west to the line of Xonfidential in the east — extending thousands of inmadsat out.
The data requirements alone would be astronomical remembering that normal radar installations are getting instant feedback from a circular sweep of around nautical miles. Jindalee is tasked to do certain things at certain times.
If crashed where they are looking and someone was watching, it would have gone in right there on the screen, and no need to go roaring down to the southern Indian Ocean like they did. Also Abbott was very slow off 22014 mark if they really did have radar intel. Something Nobody seems to give much thought too is the claim MH dropped to 5,ft and flew west through the Straits of Malacca is physically impossible within the timeframe available, just 39 minutes.
Butterworth Radar saw the unidentified aircraft over Pelau Perak at precisely To cover that distance MH would have to have flown at kt TAS, something quite impossible flying at 5,ft, or even at 12,ft.

MH could not have flown this route in the time prescribed at kt TAS at altitudes less than 32,ft and in that case would have been high enough for half a dozen radar stations to spot it.
This also disproves the claim that Confieential flew low over Kota Bharu.
It is time the whole claim that MH turned back and flew west was challenged. It simply does not stack up. Finding MH and rescuing its passengers is only possible by taking into account the following factual incidents of its landing. And ocean searches are futile when the overwhelming possibility of landing is ignored.
Though some people including children in our area had looked in wonder at the large plane but nobody in their wildest of imagination could ever think it was MH assuming it to have crashed in the South China sea or hijacked into nearby areas. More the so since to carry out their failed third objective of crashing in our area MH needs to be parked in airfields in neighbouring countries or in India itself near to our area close to the southern tip of India and not far away in Africa or Australia.
After getting really moved on reading your news article interview by Moni Basu in CNN I decided to send this vital mail which will crucially help you find the missing MH and wife and mother of your beloved daughter as also other passengers.
The real life incidents though unbelievable are true to its fullest extent and and is a definitive lead. Copies of the over characters cimplaints sent to the authorities can be forwarded for your valued perusal. I cannot afford not to complain and take up the matter since myself being the primary target and so with the plane stashed away in neighbouring countries poses immense and imminent danger. So international cooperation and coordination is imperative for which tactful handling is required so as not to hurt national sensibilities even as the extensive and well entrenched rogue sections are isolated and exposed.
With no nearby airports and our area being neither civil nor military flight corridor there is no reason for the B MH to overly our area and that too directly overhead other than to crashland here. Though there is less of a chance of a second attempt here due to Divine Grace and Protection but World capitals are all the more at risk from its reuse or such use of other passenger planes.

And far from being just a law enforcement one due to the coverup the issue is already turning into a confiedntial stakes military matter. Your email address will not be published.

Considerations on defining the search area – MH
Mattty, What do you make of this? I actually left a comment on that story, just pasted it in. At low altitudes, a Boeing is aerodynamically limited how fast it can fly. Leave a Reply Cancel reply Your email address will not be published.
