you want to put a stop to aeroplanes?
Another plane crash?

It's the only sane thing to do with thousands being killed every week by these deathtraps

I always said nowt good would become of it.
Most of today's air accidents are computer related.
Reading the prof pilots forum, most long haul pilots say the same thing.
They are trained only to be computer operators and flying by the seat of the pants, especially in an emergency has long gone out of the window and in most cases is no longer possible anyway.

It takes a series of things to fuck up before disaster strikes. Hence why they are so rare.
If it wasnt for the vast improvements these computers make the pilots would be flying by the seat of the pants much more often.

Give some examples of a plane crashing due to a computer error. The latests have been suicide pilot and surface to air missile and poor weather. The one in the Hudson was a bird strike. The one in Samui was due to weather/pilot misjudgement.....
Im pretty sure there was an incident where a plane lost all but the most basic of controls and the pilot managed to gluide the thing across the Atlantic and land it safely.

..and a good thing to.
Aircraft computer systems have become increasingly complex and complicated and way beyond the understanding of most pilots unless of course they have time to read a thousand page book of instructions as they nosedive towards disaster.

Lots of them, it's usually a case of rubbish in and rubbish out when a system has failed and the pc gives totally wrong information, where under normal circumstances a pilot would have been aware what the problem was and able to counteract it.
The Air France disaster was one of a few which occurred because a blocked pitot tube left the computer totally confused and hence aircrew without a clue what to do until it was too late.

Not often the tubes remained blocked though. Often they freeze, then unfreeze again. Just got oto find ways of stopping it happening. Planes are much much safer not as result of the technology.
Re: Air France crash. Did the computer or humans decide which route to take?
At 1h 36m, the flight enters the outer extremities of a tropical storm system. Unlike other planes' crews flying through the region, AF447's flight crew has not changed the route to avoid the worst of the storms.

The last air crash doc i watched last week related to an airbus flight testing the computer system reactions under various circumstances.
The final test was to ensure that the computer would bring the craft under control if a stall situation began to develop.
Unfortunately it didn't do as programmed by which time it was too late for the crew to save the plane and themselves.

f***ing scary innit? i dare not fly....

Look at the Air France crash... Pilots f***ing up, again.
The Airbus's stall alarm is designed to be impossible to ignore. Yet for the duration of the flight, none of the pilots will mention it, or acknowledge the possibility that the plane has indeed stalled—even though the word "Stall!" will blare through the cockpit 75 times. Throughout, Bonin will keep pulling back on the stick, the exact opposite of what he must do to recover from the stall.
The plane has climbed to 2512 feet above its initial altitude, and though it is still ascending at a dangerously high rate, it is flying within its acceptable envelope. But for reasons unknown, Bonin once again increases his back pressure on the stick, raising the nose of the plane and bleeding off speed. Again, the stall alarm begins to sound.
Still, the pilots continue to ignore it, and the reason may be that they believe it is impossible for them to stall the airplane. It's not an entirely unreasonable idea: The Airbus is a fly-by-wire plane; the control inputs are not fed directly to the control surfaces, but to a computer, which then in turn commands actuators that move the ailerons, rudder, elevator, and flaps. The vast majority of the time, the computer operates within what's known as normal law, which means that the computer will not enact any control movements that would cause the plane to leave its flight envelope. The flight control computer under normal law will not allow an aircraft to stall, aviation experts say.
But once the computer lost its airspeed data, it disconnected the autopilot and switched from normal law to "alternate law," a regime with far fewer restrictions on what a pilot can do. In alternate law, pilots can stall an airplane.
It's quite possible that Bonin had never flown an airplane in alternate law, or understood its lack of restrictions. Therefore, Bonin may have assumed that the stall warning was spurious because he didn't realize that the plane could remove its own restrictions against stalling and, indeed, had done so.

Madness, most have been pilot error or outside influence such as a bloody great missile being fired at them, for example.

The computer wrongly identified the missile as another harmless effort on goal by Altidore!
