As you can see, the expert pilots fly very straight. The flight of 77 was crap. He varied the bank and pitch in a non pilot way. But a non pilot idiot could fly and hit buildings as done on 9/11 with ZERO training. You should research this, many people have put in new pilots in the exact simulators, which are harder to fly than the real plane, and hit buildings the first time.
Turbulence? What time was the impact? You know, on 9/11 was not a big day for turbulence. And the terrorist on 77 came in at high speed and a high angle. Normal landing angles are 2.5 to 3 degrees; 77 came in at 4 to 6 degrees, not level, never at the same precise pitch for more than a second, and his bank angle was floating around like a new pilot who was not interested in flying. It seemed he was only trying to hit the biggest office building around. Bet he could not find the White house, it is too small. You have failed to bring facts, are you unable to find facts on 9/11?
The flying you saw on 9/11 was not the best, it was inexperience pilot at best. You do not understand a bad flight, bad flying looks okay from the ground, but sucks if you are in the plane. These pilots lacked the experience to do even simple turns like you are use to.
In my 34 years of flying I know anyone could fly the way the terrorist did, and without prior flight training. I have trained new pilots in 300,000 pound aircraft. You are not correct, there was no precision at all you have failed to do research; you have failed to get the minimum knowledge on flying. Total failure.
