The capability to "take control" of ANY aircraft, in flight or otherwise, has been installed on ALL major airplanes since the Mid-1970s. ...:

"In the mid-seventies America faced a new and escalating crisis, with US commercial jets being hijacked for geopolitical purposes. Determined to gain the upper hand in this new form of aerial warfare, two American multinationals collaborated with the Defense Advanced Projects Agency (DARPA) on a project designed to facilitate the remote recovery of hijacked American aircraft.

"Brilliant both in concept and operation, “Home Run” [not its real code name] allowed specialist ground controllers to listen in to cockpit conversations on the target aircraft, then take absolute control of its computerized flight control system by remote means.

"From that point onwards, regardless of the wishes of the hijackers or flight deck crew, the hijacked aircraft could be recovered and landed automatically at an airport of choice, with no more difficulty than flying a radio-controlled model plane. The engineers had no idea that almost thirty years after its initial design, Home Run’s top secret computer codes would be broken...

"When the multinationals and DARPA finally came on the scene in the mid-seventies, aircraft systems were even more advanced, with computers controlling onboard autopilots, which in turn were capable of controlling all of the onboard hydraulics. In combination these multiple different functions were now known as the “Flight Control System” or FCS...

"In order to make Home Run truly effective, it had to be completely integrated with all onboard systems, and this could only be accomplished with a new aircraft design, several of which were on the drawing boards at that time. Under cover of extreme secrecy, the multinationals and DARPA went ahead on this basis and built “back doors” into the new computer designs.

"There were two very obvious hard requirements at this stage, the first a primary control channel for use in taking over the flight control system and flying the aircraft back to an airfield of choice, and secondly a covert audio channel for monitoring flight deck conversations. Once the primary channel was activated, all aircraft functions came under direct ground control, permanently removing the hijackers and pilots from the control loop.

"Remember here, this was not a system designed to “undermine” the authority of the flight crews, but was put in place as a “doomsday” device in the event the hijackers started to shoot passengers or crew members, possibly including the pilots. ..."

Once SomeOne, ANYONE, has access to the codes, all bets are off whether any particular flight will make it to it's destination.
