The above graph is taken from the DSTG book “Bayesian Methods in the Search for MH370, ” page 90. It shows the probability distribution of MH370’s endpoint in the southern Indian Ocean based on analysis of the different autopilot modes available to whoever was in charge of the plane during its final six hours. It was published earlier this year and so represents contemporary understanding of these issues. As you can see, the DSTG estimated that the probability that the plane hit the 7th arc north of 34 degrees south longitude is effectively zero.

I interviewed Neil Gordon, lead author of the paper, on August 11. At that time, he told me that experts within the official search had already determined that the BFO values at 0:19 indicated that the plane was in a steep descent, on the order of 15,000 feet per minute.

Such a rate of descent would necessarily indicate that the plane could not have hit the ocean very far from the 7th arc. Nevertheless, Fugro Equator, which was still conducting its broad towfish scan of the search area at the time, spent most of its time searching the area on the inside edge of the search zone in the main area, between 37.5 and 35 degrees south latitude, about 25 nautical miles inside the 7th arc. At no point between the time of our interview and the end of the towfish scan in October did Equator scan anywhere north of 34 degrees south.

Shortly thereafter, the ATSB hosted a meeting of the experts it had consulted in the course of the investigation, and the result of their discussion was published on December 20 of this year as “MH370 – First Principles Review.” This document confirms what Gordon told me, that the group believed that the BFO data meant that the plane had to have been in a steep dive at the time of the final ping. What’s more, the report specified that this implied that the plane could not have flown more than 25 nautical miles from the 7th arc, and indeed most likely impacted the sea within 15 nautical miles.

By the analysis presented above, a conclusion is fairly obvious: the plane must have come to rest somewhere south of 34 degrees south, within 25 nautical miles of the seventh arc. Since this area has already been thoroughly scanned, then the implication is that the plane did not come to rest on the Indian Ocean seabed where the Inmarsat signals indicate it should have.

I would suggest that at this point the search should have been considered completed.

Nevertheless, the “First Principles Review” states on page 15 that the experts’ renewed analysis of the 777 autopilot dynamics indicates that the plane could have crossed the 7th arc “up to 33°S in latitude along the 7th arc.”

Then in the Conclusions section on page 23 the authors describe “a remaining area of high probability between latitudes 32.5°S and 36°S along the 7th arc,” while the accompanying illustration depicts a northern limit at 32.25 degrees south.

In other words, without any explanation, the northern limit of the aircraft’s possible impact point has moved from 34 degrees south in the Bayesian Methods paper in early 2016 to 33 degrees south on page 15 in the “First Principles Review” released at the end of the year. Then eight pages later within the same report the northern limit has moved, again without explanation, a half a degree further north. And half a page later it has moved a quarter of a degree further still.

Is the ATSB sincere in moving the northern limit in this way? If so, I wonder why they did not further search out this area when they had the chance, instead of continuing to scan an area that they apparently had already concluded the plane could not plausibly have reached.

I should point out at this point that the area between 34 south and 35.5 south has been scanned to a total widtch of 37 nautical miles, and the area between 32.5 and 34 has been searched to a total width 23 nautical miles. Thus even if the ATSB’s new northern limits are correct, they still should have found the plane.

As a result of the above I would suggest that:

a) Even though most recent report describes “the need to search an additional area representing approximately 25,000 km²,” the conduct of the ATSB’s search does not suggest that they earnestly believe that the plane could lie in this area. If they did, they could have searched out the highest-probability portions of this area with the time and resources at their disposal. Indeed, they could be searching it right now, as I write this. Obviously they are not.

b) The ATSB knew, in issuing the report, that Malaysia and China would not agree to search the newly suggested area, because it fails to meet the agreed-upon criteria for an extension (“credible new information… that can be used to identify the specific location of the aircraft”). Thus mooting this area would allow them to claim that there remained areas of significant probability that they had been forced to leave unsearched. This, in effect, would allow them to claim that their analysis had been correct but that they had fallen victim to bad luck.

c) The ATSB’s sophisticated mathematical analysis of the Inmarsat data, combined with debris drift analysis and other factors, allowed them to define an area of the southern Indian Ocean in which the plane could plausibly have come to rest. A long, exhaustive and expensive search has determined that it is not there.

d) The ATSB did not fall victim to bad luck. On the contrary, they have demonstrated with great robustness that the Inmarsat data is not compatible with the physical facts of the case.

e) Something is wrong with the Inmarsat data.

Australian officials have concluded that the $180 million search for missing Malaysia Airlines Flight 370 has failed. In a report timed to coincide with the wind-down of the two-year-long inspection of the southern Indian Ocean, a panel of experts convened by the Australian Transport Safety Board opined that the plane most likely lies somewhere in a zone of open ocean about the size of New Hampshire to the northeast of the current search area.

This new zone probably won’t be examined. The three countries responsible for the search — Australia, Malaysia, and China — have already stated that no further attempts to find the plane will be undertaken, unless compelling new evidence emerges.

In short, the biggest mystery in the history of modern aviation doesn’t look like it will be solved anytime soon. So it’s a good moment to take stock about what we know and what to expect in the future as we try to make sense of frustrating and tragic irresolution:

The investigators now say they have a pretty good handle on how the plane went down.

Ironically, while admitting failure, the Australian report reflects the experts’ increased confidence that they understand more or less what happened the night of the vanishing.

Based on automatic signals — “pings” — exchanged between the plane and a navigation satellite during the final six hours MH370 was in the air, investigators believe that after the airliner vanished from radar screens over the Malacca Strait it must have taken a final turn to the left and flown south on a magnetic compass heading (one of several possible navigational modes a plane can use). It then flew straight until it ran out of fuel and dived into the ocean at high speed, smashing apart into small fragments.

The scenario would be consistent with pilot suicide, but the report does not mention the secret Malaysian police report leaked earlier this year that revealed that captain Zaharie Ahmad Shah had saved a set of points on his home flight simulator in which he flew with zero fuel in the remote southern Indian Ocean. The simulator data could reasonably be interpreted as evidence he planned a suicide flight, or it could be a freak coincidence. The ATSB has long maintained silence regarding the possible identity of the perpetrator, saying that its job is to figure where MH370 went, not why it went there.

The plane is almost certainly not in the huge patch of ocean investigators spent two years searching.

The investigators long believed that the plane’s impact point lay within a nearly 50,000-square-mile rectangle calculated by Australia’s Defense Science Technology Group. But this high-probability zone has now been searched out using towed side-scan sonar arrays and autonomous underwater vehicles. Apparently, the plane isn’t there.

Some observers have speculated that the wreckage might have been missed by the sonar scan, perhaps falling into the shadow of a seamount or the depths of a ravine. The report, however, throws cold water on this idea, explaining that the technology is capable of searching all but the most rugged 1.2 percent of the search area, and therefore, “There is a high degree of confidence that the previously identified underwater area searched to date does not contain the missing aircraft.”

The new proposed search area probably won’t be examined.

If the plane isn’t in the priority search area, then it must be somewhere else. But the range of possibilities is limited. If it crashed any farther north, the debris field would have been spotted during the massive aerial search conducted just after the disappearance. If it crashed south of the current search area, debris would have been swept to the coast of Australia and likely been discovered by beachcombers. By a process of elimination, then, the endpoint could only be in a fairly tightly constrained area, about one eighth the size of the current search zone and adjacent to its northeastern edge.

“The participants of the First Principles Review were in agreement on the need to search [this] additional area,” the report states. But this extra area is large — about 10,000 square miles — and it would take months and tens of millions of dollars to scan. In its previous agreement with China and Malaysia, Australia stipulated that the search would only continue if “credible new evidence leading to the identification of a specific location of the aircraft” were found. This new analysis will not likely fit that bill.

What if the new area is searched and the plane still isn’t found?

That, the report states, “would exhaust all prospective areas for the presence of MH370.” That is to say, if the plane isn’t there, then the searchers weren’t just unlucky, their analysis was altogether wrong, and something else entirely must have happened to the plane.
But what? One possibility is that they misinterpreted one of the satellite pings. For instance, the ATSB has long puzzled over the value of the final ping but recently became convinced it must indicate that the plane was plummeting in a steep, fatal dive. If this conclusion is wrong, and the plane was instead being held in a long Sullenberger-esque glide by a suicidal pilot, then the plane’s endpoint could lie anywhere in a much larger swath of ocean.

Another possibility is that the ATSB misinterpreted all the satellite data. After MH370 disappeared from radar over the Malacca Strait, it was electronically invisible, flying over empty ocean in the dark of a moonless night. It could have gone anywhere in the world and no one would have been the wiser. Then, mysteriously, just three minutes later, its satellite communication system switched back on. This is not something that happens accidentally, or that most pilots know how to do. And yet, it is this baffling event that provided everything investigators know about the plane’s final hours. Could this strange satcom behavior have been the result of tampering by sophisticated hijackers, in order to feed investigators misleading clues? Twice I’ve asked teams within the investigation whether the satcom data could have been altered; both times they told me that they assumed that it was good.

Now that the ATSB has thrown in the towel, such questions will remain in limbo. The search will not be officially ended, only suspended. This means that according to international aviation treaties search officials will not have to issue a comprehensive final report. And so potentially vital clues about the fate of the airplane will remain hidden away indefinitely.

The mystery will endure.

(This article originally ran on December 21, 2016, in New York magazine.)

The search isn’t officially over yet–the crew of the Fugro Equator still has a Christmas and New Year’s at sea to look forward to, as well as most of the month of January–but it looks like Australia is throwing in the towel on the current seabed search as it issues its First Principles Review looking at what it learned during the last three years and where it thinks the plane’s main wreckage still might be.

The upshot of the report is quite similar to the postmortem posted here in September entitled Commentary on Neil Gordon Interview. In short, the First Principles report argues that the debris most likely is located in a small (25,000 sq km) area to the northeast of the 120,000 sq km search area, and that if it isn’t there, the ATSB has no idea where it is.

Personally, I’d like to see them go ahead and search that area, but as I read the tea leaves Malaysian and China will not allow it. They’re done. (They’ve heard the “we’re absolutely certain it’s in this area but oops it’s not so we promise it’s in the next area” line before.)

So what did the report contain that was new?

What we didn’t learn, to my great dismay, was anything about the biofouling or anything more about the mechanical breakage of the debris, and what it could have told us about how the plane came apart. Patrick De Deckker’s findings might be buried forever.

There were, however, some interesting revelations:

• For the first time, the ATSB went into some detail explaining just how much of the seabed it might have missed because the seabed terrain was too steep or rough. They reckon this to amount to about one percent of the total.
• Search team members agreed that “the distance required to be searched from the arc could be reduced to 25 NM from the 7th arc.” At one time officials believed that the plane could have gone as far as 100 nm, so excluding that possibility greatly reduces the search zone size.
• For the first time, the ATSB has said that the quantity of debris collected in the western Indian Ocean by itself is useful in reducing the search area: “From the number and size of items found to date from MH370 there was definitely a surface debris field, so the fact that the sea surface search detected no wreckage argues quite strongly that the site where the aircraft entered the water was not between latitudes 32°S4 and 25°S along the 7th arc.”

For me, the most exciting part of the report is the section provided by the CSIRO discussing how the debris might have drifted. The piece de resistance is a photograph provided by the French showing how the actual Réunion flaperon floated when put in the test tank (above). There are two stable states, both of which require heavily-encrusted parts of the flaperon to stick out well clear of the water. This is clearly impossible–barnacles can not live high and dry.

In the past, during discussions of this topic on this forum, people have said, “but wave action might flip the flaperon over so the whole thing might stay wet.” I’ve pooh-poohed this, saying that the flaperon looked quite heavy, and riding low in the water it would be no meant feat for a wave to flip it over. But lo and behold, the report contains a fifteen second video of a replica flaperon being tossed around in a choppy sea by 20 knot winds, and by god if it isn’t flipping over all the time. And therefore I acknowledge that it’s easy to imagine a flaperon getting continually flipped over, so that no barnacle would stay out of the water for more than a few seconds. However, what I cannot imagine is that a state of 20 knot winds is going to persist for 15 months. At some point, the wind is going to die down, and all the barnacles on the high side are going to die. Then the wind will pick up, the flaperon will get flipped over, and the barnacles on the other side will die. The only barnacles that would be able to survive such flip-flopping would the those in the band between the two exposed “poles.”

This is a really obvious problem that the French addressed in their own original secret report (though as I’ve written they couldn’t reconcile it). I find it a little surprising that CSIRO didn’t engage in the topic at all. I wish they’d let me write the questions for their FAQ!

As it stands, I feel that the photograph above provides a huge clue as to what happened to MH370.

UPDATE 12/20/16: To clarify this “huge clue,” here are some pictures of the trailing edge, which according to the French tank test should have been sticking out of the water (right-click to expand). (You can see a video of a replica floating in this way here.)

 

 

As As I wrote back in September, Patrick De Deckker is an Australian scientist to whom the French authorities entrusted a 2.5-cm-long Lepas anatifera shell.  De Deckker has analyzed the shell to determine the ratio of magnesium to calcium within it. Because this depends on the temperature of the water in which the barnacle is growing, and the shell is laid down sequentially like the rings of a tree as it gets bigger, the barnacle can essentially serve as a record of the water temperature of the ocean it floated through. This raises the question: can this analysis tell us something about the route the flaperon traveled?

In August, De Deckker told an Australian journalist: “The start of the growth was around 24 degrees (Celsius) and then for quite some time, it ranged between 20 and 18 degrees (Celsius). And then it went up again to around 25 degrees.”

To me this suggested an obvious route of inquiry: all we had to do was sift through the Global Drifter Program for drifters that wound up in the vicinity of Réunion during the months of July or August of any given year (the flaperon washed up at the end of July, 2015) and see which of them experienced that kind of temperature profile.

I asked for volunteers to help sift through NASA or NOAA databases available online, but no one came forward. Fortunately, my brother-in-law John Swart, a database whiz, came to my rescue. He gave me a copy of Filemaker and showed me how to import data from NOAA’s Global Drifter Program.

Every day, four times a day, these drifters transmit their position and temperature via satellite to the nerds at NOAA. Using this location information we can plot how each one arrived in the vicinity of Réunion. In the Google Earth screengrab above you can see the path that each of 16 drifters took from the start of the calendar year to July/August (the data spans from 2000 to 2015). The upshot: many of the drifters started out fairly close to Réunion, and sort of swirled around. Some came from fairly far away, however–some from the northeast, others from the east or southeast (the direction of the 7th arc).

You can view the drifters’ movement by dropping this .kmz file into Google Earth.

So how did all these paths relate to temperature? With Mr Swart’s help I tabulated all the temperature data for the 16 drifters I examined. Here are the results for 12, as much as will fit in a Filemaker chart (click to expand):

Not that, as time passes, the range of temperatures shrinks, as the drifters converge on the waters near Réunion. (If you have FileMaker you can look at the underlying data set here. CSV here. Excel here.)

I should point out that according to the world’s leading Lepas Anatifera expert, Cynthia Venn of Bloomsburg University, barnacles this size are probably only a couple months old, perhaps as much as four months if we want to be really conservative. So we should look for a U-shaped temperature pattern somewhere between day 90 and day 210.

The closest we see to this pattern would, I suppose, be drifter 71030 or 41337. But neither of these experienced water temperature lower than 21 degrees. (Of the four drifters that didn’t fit on the graph,  the coldest temperature experienced was 23 degrees.)

To my mind, this suggests that the flaperon may not have arrived at Réunion through a natural process of drift.

To be sure, there are other possible explanations for this apparent anomaly. We don’t really know, or instance, how accurate Dr De Deckker’s paleothermometry really is. And it may be that by statistical fluke the flaperon happened to wander off into cold water and back again.

But these findings emerge in the context of other hard-to-explain aspects of the recovered aircraft debris:

— As confirmed by French investigators, the flaperon somehow acquired a population of Lepas barnacles even though its natural tendency was to float high in the water

— The majority of the debris has been collected in a statistically unlikely way

— The majority of collected debris is uncharacteristically devoid of marine life

— On the pieces that do have marine life, it appears to be too small given the amount of time spent at sea.

Taken together, these incongruities raise significant doubts about the provenance of the MH370 debris recovered to date.

While the Australian authorities have bent over backwards to explain their analysis of the Inmarsat data and how it lead them to define the seabed search area, they have been completely silent on the topic of biofouling (except to say that it exists). I wonder if it is because, like the French investigators who were unable to reconcile how high the flaperon floated in the water, they are stumped by inconsistencies in their data.

Australian officials have stated that they will release a comprehensive report on their findings after the seabed search is finished. Given that the last ship, the Fugro Equator, has now started its final stretch at sea, and the last mission lasted about six weeks, the search will likely be wrapped up by the end of January. Hopefully we will have some answers soon after that.

UPDATED 12/12/16: Just to underline the extraordinary implausibility of Blaine Alan Gibson’s finds, I’ve taken the extra step of putting in bold the three (3) separate occasions when Gibson hit the jackpot with a one-in-a-million stroke of luck. See if you can spot them below. My personal favorite is the one with the ATV.

On December 8, 2016, the Twitter account voice370 (@cryfortruth) Tweeted the following:

Another piece of potential debris washed up the shore and found by B.A. Gibson on the same beach where NOK Jiang found a piece yesterday. pic.twitter.com/PdXCkYX4oI

— voice370 (@cryfortruth) December 9, 2016

In a Facebook post the same day, Grace Subathirai Nathan (one of the NOK on the current debris-finding expedition to Madagascar) posted about the same find:

Another piece of debris found earlier today. This time by private citizen Blaine Alan Gibson while he was with two French journalists Pierre Chabert and Renaud Fessaguet.
He walked past the spot on the beach where next of kin Jiang Hui found a piece yesterday and nothing was there then 30 mins later on the way back the waves washed the piece on debris to the shore.
This just goes to show that debris can be there one minute and gone the next and vice versa.

She included some of the images that were also in the Tweet, among them this one:

I’ve already written in the comment section of the preceding post that I find it quite extraordinary that a purported piece of MH370 apparently washed up on the shore within half an hour of Blaine’s passing by the spot. The ocean is vast, the number of pieces of MH370 necessarily limited. The odds of finding a piece of the plane on any given stretch of sand is very small; the odds of finding something that washed ashore within the last half hour must be infinitesmal.

One would also would not expect a newly washed-ashore piece of debris to be free of biofouling, as I’ve discussed before. Something that just came out of the ocean, if free of biofouling, must have spent time ashore, gotten picked clean, then washed back out to sea, only to come ashore again within a few days. Truly miraculous.

I’ve voiced suspicions in the past about Gibson’s self-financed investigation. He said that he found his first piece of MH370 debris, so-called “No Step,” 20 minutes after starting his first beach search. Though it was found on a sand bar that is awash at high tide, it, too, was remarkably free of biofouling. Since then, he has found more than half of the pieces of suspected debris. All have have been completely innocent of marine life. His finds have excited remarkably little enthusiasm among the authorities; the Malaysians waited six months to retrieve one batch, and then only made that effort after their inaction was the subject of unflattering news stories.

Gibson is clearly an eccentric; before he found “No Step” he was bouncing around the Indian Ocean littoral, investigating crackpot theories and making himself known to the authorities and next-of-kin. In the past he has, he says, tried to find the Ark of the Covenant. A recent article in the Guardian had this bit:

Blaine Gibson, a lawyer turned investigator who arrived on Madagascar six months ago, said he has seen debris from the plane used to fan a kitchen fire by a nine-year-old girl on the island.

“It was light and it was solid and it was part of the plane,” said Gibson, 59. “When I put the word out around the village, another guy turned up with another piece he had been using as a washing board for clothes.”

Are we to believe that he walked up on a girl fanning a fire and, lo and behold, she happened to be fanning it with a piece of MH370? Instead of any of a billion suitable small, light, flat objects that exist in the world? What’s more, I am troubled by Gibson’s suggestion that the residents of this region are so materially impoverished that they would eagerly size on any scrap of material that comes their way and put it to immediate use—to incorporate into a shelter, to burn for fuel, to fan a fire with, or to use as a washboard. In fact I find this idea rather bonkers.

Some people feel that it is unacceptable to question Blaine Alan Gibson; they say that he has inspired and given hope to the next-of-kin. As I’ve said before, I feel that if we are going to solve this mystery, we have to put every piece of evidence under intense scrutiny, regardless of however someone may or may not feel emotionally about that scrutiny.

Indeed, I find the fact that Gibson and his associates try to aggressively silence questions about his finds even more arousing of suspicion.

UPDATE 12/11/16: A couple of points I’d like to add to the above:

— In September, Gibson enlisted the aid of Australian aviation journalist Geoffrey Thomas in claiming that two pieces of debris that he’d found likely came from the electronics bay, showed evidence of fire damage, and therefore supported the hypothesis that the plane had come to grief due to an accidental fire. This theory, while favored by some, is very much at odds with other evidence in the case. Australian authorities responded by saying that “contrary to speculation there is no evidence the item was exposed to heat or fire.”

— More on Gibson’s background from SeattleMet:

For the next 25 years, Gibson lived a life that could be described as unconventionally adventurous. After a short stint at Seafirst, he moved to Olympia and worked for three years in the office of Washington state senator Ray Moore. Then he joined the U.S. Department of State. But he didn’t last long there either; in the late ’80s he could see that the Soviet Union was on the verge of collapse and decided to capitalize on it. For 10 years he lived off and on in the newly capitalist Russia, serving as a consultant to new business owners and fattening a bank account that would later fund his globe-trotting.

When I interviewed him after the “No Step” find, he told me that he speaks fluent Russian.

— Based on the total quantity of debris found in the last year and a half, one observes that the pieces turn up quite infrequently. Yet Gibson has now twice found debris with a camera crew present. In June he found three pieces while accompanied by a crew from the France 2 TV show “Complément d’enquête.” From the same SeattleMet piece:

In the first week of June he did, in fact, go to Madagascar. And on June 6 he led a French television news crew to a thin strip of land off the island’s east coast. They rode quads along the beach, and at the north end he signaled for the party to stop. The camera crew had a good reason to follow him: He is, to this day, still the only person to find a piece of Flight 370 while actually looking for it. And he’d done enough research to have a good idea where he might find more. But come on, it was still a one-in-a-million find. There’s no way he’d actually uncover another.
Right?

With the cameras trained on him, Gibson dismounted and started walking. And as he got closer to the object that had caught his eye, he could see that it was gray fiberglass. It was almost a clone of No Step. Later, he found a handful of other pieces, one of which looked exactly like the housing for a seat-back TV monitor. He couldn’t be sure, but he had a pretty good idea they came from Flight 370.

To recap, Blaine and a TV crew rode in ATVs along the beach until he signaled them to stop, got out, and pointed to a piece of MH370 debris. Holy. Shit.

— This is the piece that NOK Jiang Hui found the day before Blaine discovered his on the same beach. Again, pretty clean:

 

— Note: I’ve take out a paragraph in the original in which I said that the location of the debris in the sand appears to be way too far from the water to have washed up there within the last half hour. Several commenters pointed out that the piece appears to straddle the wet/dry line demarcating the high water mark, and I concede that point.

UPDATE 12/12/16: There’s a story in Der Spiegel today about a tree trunk that washed up in New Zealand. The remarkable size and density of these organisms is so striking that this entirely natural phenomenon struck those who came upon it as something fantastical and alien.

I bring this up to emphasize how extraordinary it is that all the debris recovered by Blaine Alan Gibson, and indeed all of the suspected pieces of MH370 debris save two, have been recovered in a nearly pristine state. Yes, objects which spend some time ashore can become picked clean in time. But many of the pieces of debris recovered so far have been found within hours of being deposited. As I’ve previously written in some detail, such pieces would be expected to be colonized by a variety of marine organisms. If you look at galleries of objects which have washed ashore after having spent a similar amount of time at sea, such as tsunami debris collected in the US Northwest and Hawaii, it collectively looks very, very different from MH370 debris. Don’t take my word for it; there are links to such image galleries at the end of the piece linked above.

 

A few things have happened recently in MH370 world that are worth taking note of.

No FMT. The seabed search in the southern Indian Ocean is all over but the shouting, and as a result I see that a consensus is forming that there could have been no “final major turn” into the southern Indian Ocean. Rather, if the plane went south, it must have loitered somewhere beyond the Malacca Strait until after 18.40 before finally flying a straight southerly path from 19:40 onward. This loiter, following a high-speed dash across the Malay Peninsula and up the strait, is quite bizarre, given that no attempt was made by anyone on board the plane to contact the ground, either to ask for help or to negotiate a hostage situation. So the presumption of a loiter doesn’t really shed light on motivation, it does effectively put yet another nail in the coffin of accident/malfunction scenarios.

More of the secret Royal Malaysian Police report released. Mick Rooney, aka @airinvestigate, has released a portion labelled “Folder 6: Audio and Other Records.” The new section contains an expert report analyzing the cockpit/ATC audio up to 17:21, which concludes (with less than 100% confidence) that it was probably Zaharie who uttered the final words “Good night, Malaysia 370.” It also includes ACARS data and the Inmarsat logs which had already been released back in 2014. In perusing the document I was not able to identify anything that would alter our collective understanding of the case, but I hope that others will offer their own assessments. And I applaud Mick for being the only one with the moral backbone to release this information. I am sure that more will follow. UPDATE: The next batch is here: “Folder 5: Aircraft Record and DCA Radar Data.”

Debris trail goes cold. I’ve plotted, above, the number of pieces of debris that have been found each month since MH370 disappeared. After the first piece of debris was found in July, 2015, a smattering of further pieces was found until April, May, and June of this year, when the number spiked and then dropped off again before ceasing altogether. This is a puzzling distribution, since drift models show that the gyres of the southern Indian Ocean act as a great randomizer, taking things around and around and spitting them out after widely varying periods of time. Would expect, therefore, to see the number of pieces found to gradually swell and then fall off again.

There is a complicating factor to this assumption, of course. Even if the pieces do arrive in a certain pattern, overlaid on top of this is the effect of an independent variable: the degree to which people are actively searching for them. It must be noted that a considerable amount of the June spike is attributable to Blaine Alan Gibson’s astonishing haul on the beaches of Madagascar that month. Indeed, Gibson by himself remains responsible for more than half of the 22 pieces of debris found thus far.

Earlier this week, several frustrated family members announced that they would be organizing their own beachcombing expedition, to take place next month. If their efforts prove less fruitful than Blaine Alan Gibson’s, it may raise questions as to what exactly was the secret to Gibson’s success.

Mick Rooney, aka @Airinvestigate, has released further documents from the secret Royal Malaysian Police investigation into the disappearance of MH370. I asked him if he could tell me anything about how the documents were sourced or why they are being released now, but he says that he is bound by an oath of confidentiality not to discuss further.

Those familiar with recent events surrounding the case might be able to hazard a guess.

Here are the files:

data-from-flight-simulator-computer

This 14-page document includes technical information about the data found on Zaharie’s flight simulator hard drives. It appears that the machine crashed multiple times in the months before MH370’s disappearance. The document also includes a log of when the flight sim was played, the last time being on March 15, 2014, a week after the plane disappeared (presumably this reflects activity by investigators.) Prior to that, the sim had last been played on February 20, two weeks before the disappearance. This suggests that Zaharie was not using his flight simulator to practice vanishing in the weeks before his disappearance.

This 7-page document seems to have been machine-translated from Malay, and appears to describe a preliminary investigation of the computer hard drives by a Malaysian police technician. It lists the various hard drives found with the flight-sim computer. Among the information recovered were passwords and account information for Zaharie’s hobbies and interests, as well as information about an online bookstore, Zaharie’s various social media accounts, and online shopping. Of particular note, investigators found a deleted folder labeled “777TwinTower” which contains pictures of a Malaysia Airlines plane flying toward the Kuala Lumpur city center. Given widely held suspicion that Zaharie took MH370 on a suicide flight, and that fact that terrorists flew two planes into New York’s twin towers in 2001, this will no doubt raise eyebrows. However, this document notes that: “These images have been taken from the computer screen to play a simulated airplane. The assessment believed that the owners of these computers have taken one of those images for the purpose of being used as an icon on the account.” That is to say, an innocent interpretation of this folder and its contents would be that Zaharie, a proud Malaysian 777 pilot, wanted to create an image of his plane flying past an iconic Malaysian landmark.

After a section discussing the seven deleted points from the flight simulator, which have been much discussed in this forum, the report concludes with a brief Summary: “The results of the examination of the goods were found that no any activity outside the common. The overall computer use to host gaming Flight Simulator only. Nor has any information source which directly indicates there any plans to eliminate MH370 found.”

This 31-page document appears to contain all of the saved data in the seven above-mentioned flight simulator points. Hopefully independent flight simulator experts will look it over and render an opinion for the rest of us who lack the expertise to properly grapple with it.

Overview

How does this new information alter our understanding of the MH370 mystery?

For me, it is noteworthy that so little incriminating information was found on any of Zaharie’s computers, even (especially) among the deleted files. The way we use computers these days, they are essentially extensions of our brains. Any passing fancy that drifts through our head is likely to be reflected in our internet search history, in notes we write to ourselves, and so on. When Andreas Lübitz was in the throes of his final mental dissolution, he spent a great deal of time online reading about mental disorders and researching ways to commit suicide. It’s all right there to be seen. Yet on Zaharie’s computer there is nothing. Indeed, he seems to have been spending his time prior to the disappearance doing things like making instructional DIY home-repair videos and pretending to fly an antique DC-3 airplane. Not, it would seem, the behavior of someone contemplating his imminent extinction.

In the light of this newly released information, it is easier to understand why the Malaysian police came to the conclusion that nothing about Zaharie’s behavior points to him  being the culprit.

Twitter user @AirInvestigate just tweeted this picture. Thanks to reader Ventus45 for posting the link in comments. This presumable is part of the 1,000-page Royal Malaysian Police report that the Independent Group and others have been sitting on for months.

When Victor Iannello described the contents of this report to me, he implied that the only parts that were interesting were 1) the pages describing the flight simulator hard drive data points in the southern Indian Ocean, and 2) confirmation of the Penang cell-phone tower connection with Fariq’s phone. Apparently there was nothing in the rest of it that suggested any hint of what might have happened during the fateful final flight.

Here I’ve used Google Earth to drop a 32 km radius circle centered on Bandar Baru Air Itam on top of a map of MH370’s flight path taken from the “Bayesian Methods” e-book:

UPDATE 11/12/16: @Airinvestigate has posted a second part of the document on Twitter. He describes it as “parts clipped & redacted.”

Interesting to note that the Malaysian police are on the same page with many of those here in this forum in concluding that the plane was flying in excess of 500 knots and at an altitude of 35,000 to 45,000 feet–very clearly not the behavior of someone looking for an emergency landing spot.

Earlier today, the Australian Transport Safety Board released a document entitled “MH370 — Search and debris examination update.” Perhaps occasioned by the recent completion of the towfish scan of the Indian Ocean seabed search area, the document updates earlier ATSB reports and offers some intriguing insights into what may have happened to the plane. Some thoughts:

— The first section of the report expands upon an assertion that the ATSB made in an earlier report: that the BFO values recorded at 0:19 indicate that the plane was in an increasingly steep dive. Indeed, the newly published calculations indicate that the plane was in an even steeper dive than previously reckoned: between 3,800 and 14,600 feet per minute at 00:19:29, and between 14,200 and 25,000 feet per minute at 00:19:37. On the lower end, this represents an acceleration along the vertical axis from 37.5 knots to 144 knots in eight seconds, or 0.7g. On the higher end, this represents an acceleration along the vertical axis from 140 knots to 247 knots, likewise about 0.7g. If the plane were freefalling in a vacuum, its acceleration would be 1.0g; given that the airframe would be experiencing considerable aerodynamic drag, a downward acceleration of 0.7 would have to represent a near-vertical plunge, which a plane would experience near the end of a highly developed spiral dive.

— The second section describes end-of-flight simulations carried out in a Boeing flight simulator in April of this year. These tests were more detailed than others carried out previously. Evidently, modeled aircraft were allowed to run out of fuel under various configurations of speed, altitude, and so forth, and their subsequent behavior observed. Thus, the exercise modeled what might have happened in a “ghost ship” scenario. Notably, it was found to be possible for the plane to spontaneously enter the kind of extremely steep dive described in the previous section. This being the case, the report states, the plane “generally impacted the water within 15 NM of the arc.” This is not surprising, considering that the plane had already lost altitude and was plummeting straight downward. This offers a tight constraint on where the plane could plausibly be if the 0:19 BFO analysis is correct.

Search crews in the remote southern Indian Ocean have completed a task so vast and technically ambitious that it once seemed impossible: to scan a three-mile-deep, 120,000 sq km swathe of seabed using a side-scan sonar “towfish” in hopes of finding the wreckage of missing Malayia Airlines 777 MH370. After considerable delay due to mechanical problems and bad weather, the final square miles were scanned on October 11 by the research vessel Fugro Equator. The $180 million project turned up no trace of the missing plane, though searchers did find several long-sunken sailing ships.

The Fugro Equator will next use an AUV, or autonomous sub, to scan selected areas where the rugged seabed topography was too rough for adequate imaging by the towfish. “The total combined area of the spots that will be surveyed with the AUV is very limited, but still required to ensure that no area has been missed,” says Fugro spokesman Rob Luijneburg.

The Australian National Transport Board (ATSB), which is overseeing the search, expects this fill-in work to be completed by the end of February.

The fact that that the Pennsylvania-sized towfish scan had been completed was first noticed by Richard Cole, a space scientist at University College London who has been meticulously logging the search ships’ movements via online tracking services and then posting charts of their progress on Twitter. “At the completion of Equator’s last swing in mid-October the target of 120,000 square kilometers had been achieved, at least as far as my calculations show,” Cole wrote me last week. Both Fugro and the ATSB subsequently confirmed Cole’s observation.

The 120,000 sq km area has special significance in the effort to find MH370, because ministers from the four countries responsible for the search have made it clear that if nothing turns up within it, the search will be suspended. Unless new evidence emerges, the mystery will be left unsolved.

Plans to search the seabed were first mooted during the summer of 2014, after officials realized that metadata recorded by satellite-communications provider Inmarsat contained clues indicating roughly where the plane had gone. At first, investigators were confident that the wreckage would be found within a 60,000 sq km area stretching along the 7th ping arc from which the plane is known to have sent its final automatic transmission. When nothing was found, ministers from the four governments responsible for the search declared that the search zone would be doubled in size.

In December, 2015, officials declared that the search would be completed by June, 2016. In July of 2016, Malaysia’s transport minister indicated that it would be finished by October; weeks later, a meeting of the four ministers pushed the completion back to December. Last week, the Australian Safety Transport Board announded that “searching the entire 120,000 square kilometre search area will be completed by around January/February 2017.”

In an email to me, ATSB communications officer Dan O’Malley said his organization will issue a report on the seabed search once the full scan is completed. Under ICAO guidelines, Malaysia will only be obligated to release a comprehensive final report on the investigation once it has been formally terminated; so far, Malaysia has only talked of suspending the search, not ending it.

The bulk of the work has been carried out by ships pulling a sidescan sonar device on a long cable. This so-called “towfish” uses reflected sound waves to create an image of the sea floor. By sweeping up and down the search zone in much the same way that a lawnmower goes back and forth across a lawn, searchers have been able to build up a comprehensive image of the search area’s bottom.

But, just as a landscaper might have to use a weedwhacker to clean up areas around rocks or stumps, searchers will have to fill in gaps in the scan where underwater mountains, volanoes and escarpments have prevented the towfish from getting a close enough look.

“A total area for search by the AUV is difficult to give because it concerns a number of relatively small spots that all are relatively difficult to reach and in difficult terrain,” Luijnenburg says.

The fill-in work will be carried out by an Autonomous Underwater Vehicle deployed from the Fugro Equator. The Kongsberg Hugin 100 is capable of diving to depths of up to 15,000 feet and can maintain a speed of 4 knots for up to 24 hours before being retrieved by the mothership. Whereas the side-scan sonar of the towfish has a resolution of 70 cm, the AUV’s sonar has a resolution of  10 cm, and so can image the seabed in much greater detail, as well as taking photographs when necessary.

Meanwhile, as the AUV work progresses, a Chinese vessel will deploy an Remotely Operated Vehicle (ROV) to take photographs of targets previously identified as being of interest. The ATSB has stated that none of these targets are “category one” targets, namely those likely to have come from MH370, however. Says Cole, “In the absence of category one targets there must be a list of targets from the sonar search that look the most interesting, so the question is how far down that list they are going to go.”

While the fill-in work must be carried out in order for the work to be declared 100 percent done, little prospect remains that the missing plane will be found in the southern Indian Ocean.
