Also, some of the denser components of the aircraft were found to have gone straight through and landed ahead - one of the engine cores did this.
In fact, some landing gear was more recently discovered wedged between two buildings down the road this time last year.
All the "no-plane" theories just seem to be a form of denial and it makes sense that some people would react that way, as its a horrible thing to have happened. It was such an un-precedented event (no one has ever crashed an airliner in to a mock skyscraper in testing) and so many thousands of eye witnesses that its like that thing about bumble bees: according to maths, they can't fly but they obviously can so the maths were wrong.
