I said improbable/impossible. Besides, the crux of my point was the novice pilot performing the maneuver.
Have you, a non-pilot, ever tried to fly a plane?
You will find that it isn't very hard to get it to fly where you want it to fly. Boeing designs on purpose such that they generally fly where you push them with the controls.
You will also find that you can't fly the course you're aiming quite as smoothly as an experienced pilot does. Your path will look rather wobbly.
In the end, if you aim to hit the runway, you will succeed, but might crash on the runway, and maybe your course will be off so you skid off the track. But still, you will
hit the runway.
And that's exactly what we saw Hanjour do: He managed to push the 757 where he wanted it to go, but on a pretty wobbly path. He barely managed to hit a HUGE target that is much wider than a runway and a few times as high as your plane.
So all as you would expect from an inexperienced pilot.
Shaky, yes. Not only possible, but relatively easy.
If you don't believe me, try to find yourself a flight simulator, and do it yourself. You'll be surprised how easy it is to crash a plane like the 757 into a huge target.
