Even more morbid in retrospect
Just saw this discussion from last November and December in an online forum about what would happen if a passenger jet hit the WTC. A couple of posters at the time said it was too morbid a topic to discuss... Most of the thread is about accidental collision, btw, not intentional. And most of the posters concluded that most of the damage would be to people on the ground. No experts, just people theorizing.
