This "unhackable" system sounds good, but only if its unhackable. If the hijacker could find a way to hack this, it would make things easier to kill everyone, not harder.
Think of it this way, what if the hacker were to "invert" the softwall gps coordinates so that the plane thought it were on the wrong side of the soft-wall? The plane would then automatically fly into a building regardless of what the pilot was doing.
