<p>Crowdsourcing is playing a central role in the search for Malaysia Airlines Flight MH370, which vanished on March 8, 2014.</p>
<p>The Boeing 777, which disappeared while heading from Kuala Lumpur to Beijing, had 239 people aboard. Despite an exhaustive search for the plane over the past year, no trace of it has been found.</p>
<p>In an attempt to solve the mystery, 18 scientists and mathematicians around the world put their collective expertise together and calculated the most likely place the plane crashed.</p>
<p>Based on those calculations, search efforts have been moved south from the original site where ships thought they'd detected pings from one of the plane's black boxes, to a spot further south and west of Australia.</p>
<p>Michael Exner is a satellite scientist in Colorado who helped build some the satellites being used in the hunt for MH370. He describes how satellite data and other information has been incorporated into the crowdsourced calculations of MH370's potential crash site.</p>

</div>
</div>
</div>
</div>
</div>
<div class="q-box spacing_log_answer_content puppeteer_test_answer_content"><div class="q-text"><p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>The reason MH370 is so difficult to find is because the pilot turned off all tracking except one Inmarsat beacon that he was unaware of.</span></p>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>The Inmarsat beacon only provides timing pings, which means it can only be used to provide an arc of distance away from the satellite receiver. Not an exact location</span></p>
<div class="q-box"><div class="CssComponent-sc-1oskqb9-0 QTextImage___StyledCssComponent-sc-1yi3aau-0 cfUEeh"><div class="q-box unzoomed"><img class="q-image qu-display--block" src="https://qph.cf2.quoracdn.net/main-qimg-ea80dd133c4e3e16d8fb7c67bc840699"/></div>
</div>
</div>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>What complicates this further is that the distance pattern changed for the last ping. It was not evenly spaced apart like the previous pings, it was much closer to the previous ping, meaning that the aircraft had changed course between pings.</span></p>
<div class="q-box"><div class="CssComponent-sc-1oskqb9-0 QTextImage___StyledCssComponent-sc-1yi3aau-0 cfUEeh"><div class="q-box unzoomed"><img class="q-image qu-display--block" src="https://qph.cf2.quoracdn.net/main-qimg-09b8f5e3dad674bb61a95df71156ee4c"/></div>
</div>
</div>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>To make things much worse, multiple simulations completely ignored this and gave faulty information based on fuel burn simulations, while ignoring the ping data. They literally go right past the ping and keep going. Making them basically useless. In fact, they cause more harm than good.</span></p>
<div class="q-box"><div class="q-box"><img class="q-image qu-cursor--default qu-display--block" src="https://qph.cf2.quoracdn.net/main-qimg-c57687be56da468381f020754239319d"/></div>
</div>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>The search teams assumed that the change in ping meant the aircraft had turned and flown south. So they concentrated their efforts on the southern portion of the arc.</span></p>
<div class="q-box"><div class="q-box"><img class="q-image qu-cursor--default qu-display--block" src="https://qph.cf2.quoracdn.net/main-qimg-2a9e1c45096050373558ea5468f3b502"/></div>
</div>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>But this turned out to be incorrect. Because the last ping change doesn’t necessarily mean a turn. It just means velocity away from the satellite receiver changed. It can have multiple meanings besides a turn south.</span></p>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>There is a system called WSPRnet that has shown the ability to track aircraft passively using radio transmissions as a form of radar. This system was used to attempt to recreate the flight path, and appears to show the aircraft going into a holding pattern at the last ping line. All of the WSPRnet data matches the ping data, and it has been proven by tracking thousands of other aircraft during tests. So there is an extremely high chance that it is correct and the aircraft did not turn. It probably entered a holding pattern North of the search areas.</span></p>
<div class="q-box"><div class="CssComponent-sc-1oskqb9-0 QTextImage___StyledCssComponent-sc-1yi3aau-0 cfUEeh"><div class="q-box unzoomed"><img class="q-image qu-display--block" src="https://qph.cf2.quoracdn.net/main-qimg-734c6504eb27c4ae6f544cfa014713b3"/></div>
</div>
</div>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>To make this much more complicated, the current spread debris over a huge area. So it might not even be possible to find the main wreckage. It might be in bits all over the ocean floor.</span></p>
<div class="q-box"><div class="CssComponent-sc-1oskqb9-0 QTextImage___StyledCssComponent-sc-1yi3aau-0 cfUEeh"><div class="q-box unzoomed"><img class="q-image qu-display--block" src="https://qph.cf2.quoracdn.net/main-qimg-f6cdb2a737e948f8c6a93b7c577f3b03"/></div>
</div>
</div>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>So the best that can be hoped for is that some large chunks or engine components may be found one day. And if the aircraft floated at all after crash, they are unlikely to be directly at the point of impact.</span></p>
<p class="q-text qu-display--block qu-wordBreak--break-word qu-textAlign--start"><span>This obviously makes finding the wreck an absolutely daunting task.</span></p>
