Malaysia Airlines flight MH370 makes it clear: we need to rethink black boxes                              Your  iPhone is more powerful than the evidence-collecting computers in the  cockpit. Simple changes could mean faster answers for plane crashes<img src="http://static.guim.co.uk/sys-images/Guardian/Pix/pictures/2014/3/9/1394381453126/Malaysian-Airlines-possib-009.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />         Why is a normally safe aircraft – the Boeing 777-200 – missing over the South China Sea, <a href="http://www.theguardian.com/world/2014/mar/09/malaysia-airlines-missing-plane-investigation-widens-live" target="_blank">with all 239 passengers and crew on board Malaysia Airlines flight 370 presumed dead</a>?I'l tell you why: it was a fireball ignited by faulty lithium-ion batteries carried on board by cellphone-wielding passengers.No, it wasn't. It was a bomb planted by terrorists – possibly the passengers who were reportedly carrying stolen passports.Rubbish:  it was structural failure triggered by internal damage sustained in an  airport fender-bender involving the same aircraft two years ago.These,  of course, are not answers. It would be generous to call them theories.  They are really a tiny sample in an online orgy of wild guesses that  erupted on social media over the weekend, in the hours after the  aircraft was reported missing off the coast of <a href="http://www.theguardian.com/world/malaysia" target="_blank">Malaysia</a>.As  search teams continue scanning the waves for signs of debris, these  online truth-seekers should be asking a different question: why couldn't  the plane itself tell us exactly what happened when it went off-radar?In  one of the most galling anachronisms of modern aviation technology, the  "black box" that carries most if not all of the answers seems to have  vanished, too.Depending on the location of the wreckage, it could  be days, months or even years before anyone turns up the black box –  which is usually orange – and there remains a remote possibility that  the device and its precious recordings of audio and flight sensor data  will never be found at all.The ongoing mystery of <a href="http://www.theguardian.com/world/malaysia-airlines-flight-mh370" target="_blank">Malaysia Airlines flight MH370</a>  is the fault of a bizarre quirk in our networked society. Even cars  have broadband connectivity now, but the modern jet airliner – perhaps  our most technologically evolved mode of transport – still exists in the  age of radio.Air traffic controllers today must orchestrate the  most congested airspace using primarily voice commands. You can send and  receive text messages from most aircraft, surf the web and even stream  House of Cards. The system that powers the plane is limited to  pre-dial-up internet connection speeds.There is simply no  datalink onboard an aircraft with the bandwidth to continuously stream  the volumes of data collected and stored during every second of a flight  by the flight data recorder and the cockpit voice recorder.The  result is a dangerous silence in the immediate and sometimes extended  aftermath of what appears to be the worst airline crash in more than a  decade. In the absence of data, the biological temptation to seek  patterns within the flimsiest of available evidence is overwhelming.In  the aftermath of the Air France flight 447 crash in 2009, speculation  focused on particular technologies with the Airbus A330. It took nearly  two years for an international search team to locate and raise the  flight recorders lying at the bottom of 4,700 meters of water. The  actual data told a different tale of a bizarre sequence of fatal errors  made by a confused and disoriented flight crew attempting to fly through  a major storm.Until the wreckage of Malaysian flight 370 is  found, it is impossible to know how long it will take to recover that  little box inside the 777-200.We shouldn't have to wait at all.  There are technologies in existence or development today that can  address this glaring gap in the aviation safety net.To be fair,  it's not quite that easy. It's relatively simple and cheap for a black  box to gather and store megabytes worth of flight data every second. It  is much harder and much more expensive to continuously transmit that  information by satellite or radio transmission.But even a little  data is better than almost none, which the disappearance of flight 370  makes clear. It should be rather straightforward to install a processor  connected to the black box that can select a subset of the most relevant  data. A recent patent application filed by Boeing describes such a  system, which specifies a limited data set including the precise  location of the aircraft and the flight control inputs by the pilot or  the automation system.There will be costs to mandating such a  system, but the benefits are clear. Multi-national search and recovery  teams involving a fleet of ships and search aircraft should no longer be  necessary. Critical safety data could provide clues of system or  structural failures much faster, making the entire <a href="http://www.theguardian.com/world/air-transport" target="_blank">air transport</a> system safer.Most  of all, the commercial aircraft upon which we depend for transportation  and economic growth need to finally enter the Information Age. Then  searches for missing planes won't have to resemble the hunt for Amelia  Earhart.</blockquote>
