For half a year after MH370’s right-hand flaperon washed ashore on La Réunion, no other pieces of aircraft debris turned up. Was that remarkable piece a one-off? And then, suddenly, everyting changed. The following February an American adventure-seeker named Blaine Alan Gibson found a trianguler piece of a with the words “No Step” on a sandbar in Mozambique. Experts confirmed that it, too, came from MH370. In an instant, Gibson became famous around the world, and his examples inspired others to look more carefully at coastlines in the western Indian Ocean. In short order another half-dozen had been turned in, several of them encrusted with marine organisms that could help scientists figure out where they drifted from. As they confronted all this new data, however, search officials found them grappling with some puzzles. At first, they couldn’t figure out how the flaperon had floated to La Réunion in the time in had—and once they resolved that problem to their satisfaction, they realized they were even more perplexed by the arrival of a piece of one of the engines in South Africa. Was there something about these pieces that they didn’t understand?

On July 29, 2015, a worker in the French territory of Réunion Island discovered MH370’s flaperon, the first confirmed piece of wreckage from the missing plane. It seemed like case closed, that the doomed plane crashed near the seventh arc in the Indian Ocean. But not everything added up. Between reverse drift models and sea life that was growing inconsistently on the debris, it raised the question: are we 100% sure that flaperon came from where authorities suspected?

So far in this podcast we’ve spent each episode diving into a particular aspect of the mystery. This time, we’re taking a different approach. We’re pulling back to look at the mystery from a global perspective in order to address the question: What is this case like? Just as every person has a unique character, a mystery can have a personality of its own, and MH370 certainly does. The dominant feature of that personality is strangeness. Time and again, a piece of evidence emerges which changes what we understand about the case – but then it turns out the evidence itself contains mysteries that themselves need to be elucidated. In today’s episode, we look at five of the most striking examples of this phenomena. Together, they raise the question: why is the MH370 like this? Is it just a matter of coincidence, or is there some underlying aspect of the case that keeps pulling it toward the unexpected? For more info, visit our show page at DeepDiveMH370.com.

By mid-2015, the search for MH370 had entered a kind of limbo. The designated seabed search area had been scanned without success. So what evidence was there that the plane had really gone south? Attention turned to the topic of floating debris and where it might be found. If the plane had impacted the ocean in the way the Inmarsat data implied — namely, with catastrophic velocity — then there should be many thousands of pieces of wreckage floating on the surface. Oceanographers turned to the science of drift modeling, which can produce probabilistic models of where floating objects in any given stretch of ocean might go. It seemed like the most likely place for stuff to wash ashore was going to be the western shore of Australia, where thousands of beachcombers waited expectantly. They were disappointed. But then a stunning discovery emerged thousands of miles away. For more info and for the video version of this podcast, visit our show page at https://www.deepdivemh370.com/p/episode-16-debris

Seven months after MH370 disappeared, ships leased from the Dutch maritime survey company Fugro were at last ready to begin searching the seabed that Australian scientists had defined using data mysteriously transmitted from the aircraft during its final six hours. Fugro’s ships faced a daunting task: searching a vast area, far from land, where abyssal plains and steep-walled canyons lay concealed beneath three miles of water. The search authorities were confident that success was right around the corner — at least at first. But as days turned to months turned to years without any sign of the missing plane, they began to wonder if they had made a mistake. Had one of their assumptions been wrong? Was it possible the plane wasn't in the underwater search area? And if so, where else could it have gone? More info at deepdivemh370.com.

If MH370 didn’t fly into the southern Indian Ocean but instead wound up in Kazakhstan, that implied that Russia was behind a sophisticated hijacking plot. Intrigued by the presence on the flight manifest of three Russian-speaking passengers, Jeff had already hired researchers in Russia and Ukraine to look into their background when he learned on July 17, 2014, that one of MH370’s 14 sister aircraft, a 777 operating as Flight MH17, had been shot down over eastern Ukraine. Jeff immediately suspected a possible link between the fate of the two flights, but at first, aviation experts and political pundits alike were convinced that the shoot-down had been a mistake and could not possibly have been connected to MH370’s vanishing. In time, however, powerful evidence emerged that undermined those early assumptions. More info at deepdivemh370.com. The video version of this episode can be found here: https://youtu.be/cf0lcbSNPAg

Careful analysis of satellite signals sent from MH370 to Inmarsat indicated that the plane had flown into a remote area of the southern Indian Ocean. But another possibility existed. The equipment that MH370 carried and the circumstances under which it operated together created a potential vulnerability that sophisticated hijackers could have exploited to make the plane appear to have flown south when it really headed north. If that occurred, then the plane would have flown instead to the northwest, over India, Nepal, China, and Kyrgyzstan before winding up in Kazakhstan. In today’s episode we discuss the details of the plane’s possible northern route, and explore whether it could have flown all that way without being detected by military radar.

Once the scientists at CSIRO had generated the probability distribution for the plane’s last known location on the 7th arc, the next question they had to answer was: how far did the plane travel from that point before it impacted the water? As we've discussed previously, their goal was to define a search box within which the plane was likely to be found. The plane’s location along the 7th arc defined the length of the rectangle, and the distance it could have traveled from the 7th arc would define the width of the search box. So the question of how far the plane could have flown after the last transmission depends on what the investigators thought was going on with the plane at that moment. They decided that, based on the nature of the Inmarsat signals, the plane had mostly run out of fuel and had already started its inevitable descent into the ocean. But had it plummeted steeply, or taken a long, gradual glide? More information at deepdivemh370.com.

In episode 11 of the podcast, Jeff and Andy discuss the elephant in the room: who are they to speculate on the mystery of missing Malaysia Air Flight MH370? They talk about their unique backgrounds, what brought them together for this podcast, as well as how the Bayesian Method provided authorities to look for the plane where they did.

In what’s sure to be the most controversial episode of the series so far, Jeff and Andy delve into the question of whether MH370 might have had a previously unrecognized security backdoor. In the months after the disappearance, a series of surprising facts emerged which, taken together, raised the possibility that the Inmarsat data guiding the official search might not be as infalliably trustworthy as previously assumed. One Independent Group member even identified a specific parameter in the plane’s Satellite Data Unit which, if switched, would make the plane look like it was going south when it was really going north. Whether or not this vulnerability was exploited, its existence means that there was now a second lens through which the evidence of the case could be viewed.

Do you think that this back door is a flat-out impossibility that should be discarded alongside theories of UFOs and black holes? Or a plausible hypothesis that needs to be explored further? Let us know in the comments.
