My worst student could fly a 757 into a building. flying one is the equivalent of flying a 172 into a building that is about 100 feet wide, about the same as a runway. You could see the WTC probably about 20 miles away that day, plenty of time to align up fairly well and just make one final correction right before hitting it. Again, pointing an airplane directly at a building when you have that much time is not hard, even for a horrible pilot. I don't know why you are even arguing this point, they obviously flew into the building.
As for the core collapsing first, why is this not feasable? The core has a much smaller foot print as compared to the outer shell, a much smaller amount of structural failure would start its collapse, and the beams are much closer together so that any destruction of one beam would be likely to also cause damage to other beams. Basically, the core could be brought down much easier than the outer structure, which it did. THis accounts for the initial shift of the antenna down 10 ft along with all of the core beams above it shifting down to the next lower floor. The core then continued to collapse basically straight down, being contained by the outer core. This downward pull while it was collapsing started the outer core down also, only lagging slightly behind it.
As for the "least risk point" this is where the pilot's inexperience comes in. Of course they had preferred that they hit them at the bottem, but because of the rest of the New York skyline and buildings around the WTC you would have to initiate your descent at a fairly high altitude are really drop it in at a perfect angle to miss other buildings below you and still hit the tower. Now this would have been tough for crappy pilots to do.
Still, the 60 or so floor that they did hit still isn't the "Least risk point" in the towers as well above it would be.
I really dont understand though the "least risk point". I assume that you are saying that the actual perpatraitors didn't really want very many casuaties so they hit the towers higher than you would assume, right?
