All the permutations of what can go wrong on an airplane are scary enough to speculate about. But here's a frightening reality: the Federal Aviation Administration has issued a warning that a software glitch on 787 Dreamliners could potentially cause aircraft to lose all electrical power.
So, uh, yeah. That's terrifying.
Laboratory tests have revealed that if a 787 is powered without rest for 248 days, generator units will go into what's called failsafe mode. This could happen at any time during the course of a flight, and would shut down all of the aircraft’s electrical power. According to The Independent, 787s are also "vulnerable to hacking attacks" and "difficulties with batteries that have seen them catching fire." Yikes.
