if the towers fell at anything BUT free fall I'd be worried...
When you are running at a bunker and someone hits you with a paintball (going 250FPS!!!) do you fly backwards or flip over? NO! this isn't a freakin hollywood film...
Now look at the towers, you have what 20 stories above the impact site? when those floors gather momentum and hit the already damaged floors beneath them, they aren't going to slow down.. THATS PHYSICS...
Here is another analogy, when you are driving on the highway and hit a bug, how much does your car slow down? Physically it DOES slow down, but not by any measurable amount.
