I do not know of any fly-by-wire system that allows external access (access from outside the plane).

Betcha the NSA does.

It would be the same as an outside source accessing a gaming joystick which is hardwired to the game controller.

Wireless fly by wire is still in the development phase and not incorporated on this jet.

So as I understand it an outside source could not “take over” the jet.

However, I have been wrong before too.
