All this confusion over flight 370 has me wondering if it would be possible to hack into an airplane and control the autopilot or other on-board systems in a way that the pilots couldn't regain control.
I know some basic searching reveals some articles such as this one. If the plane can't be hacked, could someone with the proper knowledge snip or disable the pilot's override?
Disclaimer: I know 0 about aviation, but I am a programmer. So my guess would be that anything that doesn't have a physical disconnect would be vulnerable to being hacked without being able to override it.
Additional Disclaimer: This is a question about curiousity / possibility, not a how-to.
