CNN just reported that the US reported that to turn the plane Westbound, either the pilot or co-pilot punched 7-8 keystrokes into a keyboard situated between the pilot and co-pilot!!! This was deliberate.
That is not entirely correct...
The aircraft can be steered from what is called the "Mode Select Panel" - which is part of the autopilot.

By simply turning these knobs to the desired setting the aircraft will do what you want it to do, automatically.
A: IAS (Indicated Air Speed) - Setting this to a set speed will make the aircraft maintain this air speed. Nose the plane down, or climb the plane up, the aircraft will automatically set the throttle in order to maintain this speed.
B: Heading (direction) - Think of this like a 360 degree compass... well.. that's exactly what it is. Set the heading (compass heading) and the plane will turn to fly in that direction and hold that heading. So, all it would have taken to turn the plane west here would be a simple turn of the knob a few to the left and the plane would have tracked west. As you will notice in the video links below, the pilots "Steering wheel" does not even move or turn during this... its a seperate system. In fact, this is how large commercial airline type aircraft are mostly flown. *Shock Horror!* "You mean they don't use the Yoke to steer the plane?" - Well, they do, but far less than you would think... far far less!
The whole thing is pretty much done by twisting these three knobs!
C: ALT (Altitude) - Controls the planes height setting... self explanatory really...
