A completely isolated system with a good old-fashioned manual switch to shut down the entire system if necessary.
One person on a plane may have issues hacking in to the 787, but what if that person was connecting his PC to a whole farm of hackers during a long-haul flight? An organization with time and resources could have a network of 10 or 20 people all working furiously to get into the system via this one person's PC. Each competent person added to the effort exponentially raises the chances of success.
I'm with everyone else. The only truly secure network is one with no physical connection to another network. If the passenger network is needed for emergency redundancy then connect it to the plane's mission critical network only via a physical switch in the cockpit that turns on an obvious light and periodically announces via voice that it is indeed connected. That same switch, when flipped, simultaneously physically disables all passenger access. This switch is covered, controlled via a key or biometric device, and separate from the one that turns on and off the passenger network.
"Please tell Microsoft about this error," is not what you want to see while in a tailspin from 50,000 feet.
