Because you can't hack a commercial plane. Even if you could the pilots can override the computer, or reboot it, and at that point they're back in control of the plane.
I've noticed a reoccurring theme to your posts. You seemed to think if tech isn't acknowledge by PUBLIC release, it's IMPOSSIBLE.
Of course there's stuff which is kept secret. As for hacking, plenty of things have been hacked into that were thought to be secure. Goodness, on a daily basis hackers find ways to circumvent security.
As a safety measure, Boeing has built in the ability for pilots to override the fly-by-wire system, giving the pilot the ultimate control over plane.

The fly-by-wire system replaces the steel cables. Period.
ya it sucks but hey,,,if it aint cable as in steel cable,,,its computer/electrical.
Engineers also left some of the original cable system intact as another backup system. In other words, Boeing has attempted to counter Murphy's Law such that if anything can go wrong there is a backup!
Hmmm..... early on the didn't the Malaysian government say this was a threat to their national security?
If you add the two together it implies they've known from the get-go what was up.
Do you have a source for that?
If that's confirmed I'm surprised they would seal the ATC communications. That will fuel some conspiracy theories and if I was a family member I'd want to know why it's sealed. I'm not even a family member and I still want to know.
Sorry in case this was posted already:
Malaysia says there's sealed evidence on MH370 that cannot be made public
MURDER BY PLANE CRASH
A hijack-proof piloting system for airliners is being developed to prevent terrorists repeating the 9/11 outrages. The mechanism is designed to make it impossible to crash the aircraft into air or land targets - and enable the plane to be flown by remote control from the ground in the event of an emergency. Scientists at aircraft giant Boeing are testing the tamper-proof autopilot system which uses state-of-the-art computer and satellite technology. It will be activated by the pilot flicking a simple switch or by pressure sensors fitted to the cockpit door that will respond to any excessive force as terrorists try to break into the flight deck. Once triggered, no one on board will be able to deactivate the system. Currently, all autopilots are manually switched on and off at the discretion of pilots. The so-called 'uninterruptible autopilot system' - patented secretly by Boeing in the US last week - will connect ground controllers and security services with the aircraft using radio waves and global satellite positioning systems. After it has been activated, the aircraft will be capable of remote digital control from the ground, enabling operators to fly it like a sophisticated model plane, manoeuvring it vertically and laterally. A threatened airliner could be flown to a secure military base or a commercial airport, where it would touch down using existing landing aids known as 'autoland function'. After it had landed, the aircraft's built-in autobrake would bring the plane safely to a halt on the runway. Boeing insiders say the new anti-hijack kit could be fitted to airliners all over the world, including those in the UK, within the next three years.
Perhaps the most unsettling information in regards to the missing Boeing 777 comes from retired 35 year Delta pilot, Field McConnell, who states that since 1995, Boeing Uninterruptible Auto Pilots have been equipped in Boeing planes. This information was apparently not released until March of 2007, following a subsequent lawsuit by McConnell. The modification was reported to the FAA, NTSB and ALPA ( airline pilots association). According to McConnell’s documents, Boeing is said to have stated that by end of 2009 all Boeing planes would be fitted with the BUAP - making them impossible to manually hijack within the plane but susceptible to remote control by the military, according the flight veteran.
McConnell and his associates further explain the device used to control aircraft through his site abeldanger.net, stating that Hillary Clinton and Rose Law Firm had originally obtained the patent for the Quartz Rate Sensor apparently used in many military crafts: “The QRS-11 GyroChip sensor is used on commercial aircraft to rotate the antenna to receive signals from satellites for the in-flight entertainment system, radar tracking and flight controls. If the aircraft is equipped with a uninterruptible autopilot, signals can be received from a satellite to remotely fly the aircraft. The sensor provides stabilization, flight control, and guidance. It also is used in missiles, Unmanned Aerial Vehicles (UAV ) and other military as well as space and industrial applications. Because of the sensitive nature of its military applications, the export of the technology is regulated.” The site continues by asserting what the device is specifically used for: “We allege that the QRS-11 can be used as part of a package of technology to guide aircraft equipped with uninterruptible autopilots turning them into weapons.”
A high-performance navigation system used primarily for automatic aircraft touchdowns promises centimeterlevel landing accuracy.
Using signals from orbiting GPS satellites and the ground-generated pseudolite signals, 110 autopilot-in-the-loop landings of a United Airlines Boeing 737 were completed. The integrity beacons provided consistent accuracies on the order of a few centimeters during each of the autopiloted runway touchdowns. The successful series was sponsored by the Federal Aviation Administration (FAA) as part of that agency's satellite navigation program.
IntegriNautics is now developing technology and products for a range of FAA, NASA, and Defense Department requirements, as well as commercial and international customers. Indeed, the first commercial sale of pseudolites took place in July 1997. The first pseudolites were sold to customers for use in applications such as aircraft landing research, indoor GPS-based sensing, and robotic vehicle control. A key element of the IntegriNautics product selection is a processor that acts as a turnkey, high-performance positioning system. Several types of GPS pseudolites are presently offered. Work is continuing with Stanford through the STTR program, run through the Langley Research Center.
