OK...this might be a bit whacky, but here goes. I think someone was able to hack into the plane's flight capabilities and shut the pilots' ability to fly the plane down, along with any ability to communicate. They then were able to fly the plane remotely. Not sure the result is any different, it's probably at the bottom of the ocean......but that's my guess.
The reason there isn't more out there about this is it would scare the sh*t out of everyone who flies, so China and the US settled on this way out of the way part of the Indian Ocean to search, while they figure out who did this cyber hijacking.
i think the radio would still work, wouldnt it?
and manual controls always override electric ones don’t they?
