I appreciate your effort to keep things simple and less confused. In times of challenge it is a necessity. But I wonder how Occam's Razor would have faired after the first plane hit the first trade tower. It would have sounded something like "man, what an accident that was." Simplicity is good, but humanity has a way of making things rather complicated.
Which is a simpler explaination in the WTC case, that a plane flying at near supersonic speed hits one of the tallest buildings in the world on a cloudless day, or that the plane was hijacked and flown into it on purpose? I would argue that it is the latter.
