Airplanes do not fly straight & level into the center of tall buildings on clear sunny days. They just don't.
I would completely agree with this. No way.
The 25th floor is not the center of a 30 floor building. If the pilot had no control of the flaps, then it can happen. Or are you saying that it is with 100% certainty that it can never ever happen? Guess you can't say that huh?
Right. If your control problems are so bad that you cannot avoid a clearly visible tall building, then you are not going to be flying straight and level either.
For this to have happened by accident, ALL controls would have to have been out. Otherwise the plane could have been crabbed or banked enough to avoid the building. If the plane had two engines, you could even have avoided the building simply by changing throttle controls.
To say a plane hit the most prominent building in that part of Italy, straight on, straight and level, with plenty of visibility, by accident is pure BS.
Some will say it is still possible this was a freak accident. Since anything can be possible if you accept high enough odds, I will say your odds of winning the lottery, twice, are better. If you want to find a benign explanation, pilot suicide for personal reasons is your best bet (which should not be ruled out).
Remember, if the public can be made to believe that it was an accident, then the terrorists will have failed in a big part of their mission: Cause terror.
If YOU were in charge, would you help the terrorists succeed, or would YOU try to deny them the result they crave. It is obvious what is going on.
BTW: Don't give me any of that "you are not an expert" crapola. I've spent lots of time flying in the Air Force, and what I just posted is obvious to anyone who knows how to fly.
