content: Every plane crash is a series of problems, it's never just one thing. It's possible a spark led to shorting some circuit, which led to some instrument misreading, which led to a confused pilot who blamed it on some other thing that had just popped up, while the co pilot was distracted, and then you find out someone in maintenance forgot to flip a switch for the redundant feature for that particular thing. It's always a long list of shit, you need a whole chain of links to crash a plane.
