Investigators still don't know what caused an EgyptAir jet to crash last year en route from Paris to Cairo, but they're seriously looking into the possibility that a co-pilot's iPhone or iPad Mini is to blame. The theory is that the co-pilot plugged the device into a socket not meant for such things, which eventually caused the lithium battery to explode and ignited a fire in the cockpit. The French-language newspaper Le Parisien details the theory about the crash that killed 66 people, with a translated summary at the Daily Beast.
"Cockpit plugs are not made for toasters or coffee pots," one source tells the French newspaper. "They’re for professional use." Earlier this month, a report in al-Jazeera said investigators had ruled out the possibility of a terrorists' bomb being to blame and were instead convinced it was an accident of some kind. "At this stage, the combustion or self-combustion of a tablet in the cockpit is the working hypothesis," a source told the outlet. In January, Fortune noted that pre-flight video from Paris' Charles de Gaulle airport showed the co-pilot putting his iPhone 6S and iPad Mini 4 atop the cockpit's instrument panel.
